- Accuracy of mandibular proximal segment position using virtual surgical planning and custom osteosynthesis platesby J. Harding, J.K. Hartsfield, A.S. Mian, B.P. Allan, S. Naoum, R.J.H. Lee, M.S. Goonewardene on 30/04/2021 at 12:00 am
The purpose of this study was to determine whether the use of custom osteosynthesis plates increased the accuracy of proximal segment position following bilateral sagittal split osteotomy in a cohort of 30 patients when compared to a control group of 25 patients who had surgery with conventional plates. Surgery was performed by a single surgeon between October 2015 and December 2017. Post-surgical cone beam computed tomography scans were segmented using Mimics Innovation Suite (Materialise NV), and surface-based superimposition was achieved using ProPlan CMF (Materialise NV).
- SH3BP2-related fibro-osseous disorders of the maxilla and mandible: A systematic reviewby Janina Kueper, Casey Tsimbal, Bjorn R. Olsen, Leonard Kaban, Eric C. Liao on 30/04/2021 at 12:00 am
Cherubism is a disorder of bony overgrowth of the jaws that manifests in childhood. SH3BP2 gene variants have been associated with cherubism; this gene plays a major role in bone homeostasis. Due to its rare occurrence, there is as yet no comprehensive understanding of the natural history and clinical course of the disease. The aim of this review was to compile and analyze all cases of SH3BP2-related cherubism and cherubism-like disorders. Thirty publications were identified, including 92 individuals from 34 families, who were diagnosed with SH3BP2-related fibro-osseous lesions of the jaw.
- Posterior occipital gunshot wound causing orbital roof blow-in fracture with encephaloceleby N. Callahan, L. Moles on 29/04/2021 at 12:00 am
Isolated orbital roof fractures are rare fractures that usually occur in conjunction with other facial bone fractures during high velocity trauma. This report concerns a patient with an isolated orbital roof fracture with encephalocele, including its diagnosis, surgical management, and clinical follow-up. This case required a multidisciplinary approach to safely repair the fracture, reduce the encephalocele, restore the orbital volume, and restore the patient’s form and function.
- Removal of patient-specific reconstruction plates after mandible reconstruction with a fibula free flap: is the plate the problem?by K. Kreutzer, C. Steffen, S. Nahles, S. Koerdt, M. Heiland, C. Rendenbach, B. Beck-Broichsitter on 28/04/2021 at 12:00 am
Computer-aided microvascular mandible reconstruction is an increasingly common procedure in oral and maxillofacial surgery. The aim of this retrospective single-centre study was to evaluate the rate and specifics of hardware removal after fibula free flap (FFF) fixation with a patient-specific reconstruction plate. The study included patients who underwent hardware removal between April 2017 and October 2019. Statistical analyses were performed regarding the different indications for plate removal (dental implantation versus complication) and the surgical approach (intraoral versus extraoral).
- Soft tissue-based registration of intraoral scan with cone beam computed tomography scanby J.T. Deferm, J. Nijsink, F. Baan, L. Verhamme, G. Meijer, T. Maal on 28/04/2021 at 12:00 am
The aim of this study was to evaluate a novel soft tissue-based method to register an intraoral scan (IOS) with a cone beam computed tomography (CBCT) scan. IOS and CBCT data were obtained from eight dentate patients (mean age 21±2 years; three male, five female) and 14 fully edentulous patients (mean age 56±9 years; eight male, six female). An algorithm was developed to create a soft tissue model of the CBCT scan, which allowed a soft tissue-based registration to be performed with the IOS. First, validation was performed on dentate jaws with registration of the palatal mucosal surface and accuracy evaluation at the level of the teeth.
- Diffusion-weighted imaging with histogram analysis of the apparent diffusion coefficient maps in the diagnosis of parotid tumoursby A.A.K. Abdel Razek, B.N. Gadelhak, I.A. El Zahabey, G.A.E.A. Elrazzak, B. Mowafey on 21/04/2021 at 12:00 am
The aim of this study was to investigate the role of diffusion-weighted imaging (DWI) with histogram analysis of apparent diffusion coefficient (ADC) maps in the characterization of parotid tumours. This prospective study included 39 patients with parotid tumours. All patients underwent magnetic resonance imaging with DWI, and ADC maps were generated. The whole lesion was selected to obtain histogram-related parameters, including the mean (ADCmean), minimum (ADCmin), maximum (ADCmax), skewness, and kurtosis of the ADC.
- Three-dimensional evaluation of distal and proximal segment skeletal relapse following isolated mandibular advancement surgery in 100 consecutive patients: A one-year follow-up studyby S. Shujaat, E. Shaheen, C. Politis, R. Jacobs on 19/04/2021 at 12:00 am
The aim of this study was to perform a three-dimensional evaluation of the skeletal relapse of the proximal and distal mandibular segments following isolated bilateral sagittal split osteotomy advancement surgery. One hundred consecutive patients (mean age 25.8±11.7 years), comprising 65 female patients (mean age 26.4±12.1 years) and 35 male patients (mean age 24.6±11.0 years) requiring mandibular advancement without genioplasty, were enrolled prospectively in the study. Cone beam computed tomography scans were acquired for each patient at three time-points: preoperatively, immediately (1–6 weeks) after surgery, and 1 year after surgery.
- Lateral skull base surgery for posterior oral cavity cancerby Z.-H. Ren, Z.-M. Yang, T.-F. Fan, H.-J. Wu on 19/04/2021 at 12:00 am
The aim of this study was to better understand posterior oral cavity cancer (POCC) and its surgical treatment. This was a retrospective study of 76 patients who were diagnosed with POCC and underwent surgical treatment. Twenty-eight patients were treated with anatomical unit resection surgery (AURS) and 48 patients with conventional surgery. After initial treatment with curative intent, the patients were followed-up regularly with clinical examinations and imaging; the median duration of follow-up was 30.9 months (range 2–67 months).
- Protuberant fibro-osseous lesion of the temporal bone: report of four cases and review of the literatureby J. Bouaoud, F. Larousserie, L. Galmiche-Rolland, C. Bouvier, A. Picard, R.H. Khonsari on 14/04/2021 at 12:00 am
‘Bullough lesions’, also referred to as protuberant fibro-osseous lesions (PFOL), are rare temporal bone lesions initially described in 1999. Since only 12 cases have been reported, several key issues, such as their origin and recommended management strategies, remain unresolved. This article reports the largest cohort included in the literature to date, comprising four patients with PFOL. PFOL appears to be characterized by female and right-side predominance. These lesions were consistently located regarding the mastoid, generally diagnosed in early adulthood, without functional symptoms, and were always fibro-osseous.
- Venous superdrainage using superficial circumflex iliac vein in deep circumflex iliac artery perforator flap with iliac crest for oromandibular reconstructionby W.-J. Wu, L. Zheng, J. Zhang, X.-M. Lv, M.-W. Huang, Y. Shi, S.-M. Liu on 14/04/2021 at 12:00 am
The deep circumflex iliac artery perforator flap with iliac crest (DCIAPF) is considered a favourable single-flap option for oromandibular reconstruction. The aim of this study was to evaluate the effectiveness of venous superdrainage using the superficial circumflex iliac vein (SCIV) in the DCIAPF for oromandibular reconstruction. The data of 22 patients (12 female, 10 male) aged 10–76 years (median 53 years) who underwent simultaneous oromandibular reconstruction with a DCIAPF were reviewed retrospectively.
- Spatial deviations of the temporomandibular joint after oncological mandibular reconstructionby W.-F. Yang, W.S. Choi, W.-Y. Zhu, C.-Y. Zhang, D.T.S. Li, J.K.-H. Tsoi, A.W.-L. Tang, K.-W. Kwok, Y.-X. Su on 14/04/2021 at 12:00 am
Spatial deviations of the temporomandibular joint (TMJ) after oncological mandibular reconstruction are important to the aesthetic and functional rehabilitation. The aim of this study was to clarify whether and how three dimensionally (3D) printed patient-specific surgical plates, and the preservation of the condyle or ramus, affect spatial deviations of the TMJ. A total of 33 patients who underwent mandibular reconstruction via computer-assisted surgery were included. Regarding absolute deviations, patients in the 3D-printed plate group showed smaller TMJ deviations compared to those in the conventional plate group.
- Evaluation of the posterior superior alveolar artery location and diameter with a newly defined stable planeby H. Akçay, F. Kalabalık, B. Tatar on 13/04/2021 at 12:00 am
The aim of this study was to analyse the vertical location of the posterior superior alveolar artery (PSAA) using a reliable new reference plane regardless of tooth and alveolar bone, and to measure the diameter in each posterior tooth region, which is of relevance to lateral sinus floor elevation surgery. A total of 270 sinuses in 139 patients were examined in this study. The A-plane was defined by A-point and the bilateral jugal points on reconstructed three-dimensional images. The distance from the PSAA to the defined plane was measured in four regions: first premolar (P1), second premolar (P2), first molar (M1), and second molar (M2).
- Endoscope-assisted greater neurovascular palatal bundle release in cleft palatoplastyby T. Yamanishi, K. Otsuki, T. Harada, T. Kurimoto on 10/04/2021 at 12:00 am
Performing surgery in the oral cavity is difficult because of the limited view of the surgical field. Intraoral surgery for infantile oral disorders, such as cleft palate, is even more challenging. Endoscopy provides a minimally invasive approach and clear surgical view in surgeries with a constrained field of view. To date, very few reports have described endoscope-assisted palate surgery for children with cleft palate. At the authors’ institution, endoscopes have been used in primary palatoplasty using the double-opposing Z-plasty technique.
- A conceptual framework for treating jaw deformities in patients with abnormal condyles: preservation versus replacement of the glenoid fossa–disc–condyle–ramusby J.C. Posnick, L.B. Kaban on 10/04/2021 at 12:00 am
This article outlines a conceptual approach to the reconstruction of jaw deformities associated with abnormalities in the mandibular condyle. The authors describe a hierarchy of reconstruction, emphasizing use of the least invasive and progressing to the most complex and invasive techniques, depending on the nature and severity of the underlying deformity, prior operations, patient age, and stage of growth. Consider joint preservation orthognathic surgical correction, followed by biological techniques for replacement of the condyle, and avoid replacing a functional temporomandibular joint based only on radiographic remodeling and concerns about potential future flare-ups of disease based on anecdotal data.
- Non-grafted versus grafted sinus lift procedures for implantation in the atrophic maxilla: a systematic review and meta-analysis of randomized controlled trialsby S.A.N. Lie, R.M.M.A. Claessen, C.A.W. Leung, H.-A. Merten, P.A.W.H. Kessler on 10/04/2021 at 12:00 am
The aim of this systematic review and meta-analysis was to critically evaluate the currently existing clinical evidence on the efficacy of graftless maxillary sinus membrane elevation for implantation in the atrophic posterior maxilla. A search protocol without limitations to November 2020 was followed by two independent researchers. Randomized controlled trials using the lateral window approach for graftless sinus membrane elevation were included. Uncontrolled, retrospective, non-comparative studies, case reports, and experimental studies in animals or cadavers were excluded.
- What has the National Cancer Database taught us about oral cavity squamous cell carcinoma?by N. Graillon, O. Iocca, R.M. Carey, K. Benjamin, S.B. Cannady, L. Hartner, J.G. Newman, K. Rajasekaran, J.A. Brant, R.M. Shanti on 08/04/2021 at 12:00 am
The wealth of data in the National Cancer Database (NCDB) has allowed numerous studies investigating patient, disease, and treatment-related factors in oral cavity squamous cell carcinoma (OCSCC); however, to date, no summation of these studies has been performed. The aim of this study was to provide a concise review of the NCDB studies on OCSCC, with the hopes of providing a framework for future, novel studies aimed at enhancing our understanding of clinical parameters related to OCSCC. Two databases were searched, and 27 studies published between 2002 and 2020 were included.
- A simple method for preconditioning radial forearm flaps in the case of an insufficient ulnar vascular supply: a retrospective clinical analysisby N. Tödtmann, A. Weber, S. Hollstein, M. Kunkel on 07/04/2021 at 12:00 am
Due to its versatile applicability, many reconstructive surgeons use the radial forearm flap (RFF) as the first choice for soft tissue replacement. Donor site limitations of the flap arise with an insufficient blood supply along the ulnar artery. This study presents a simple and safe method for RFF preconditioning by recruitment of the deep palmar arch via the ulnar artery. Fourteen patients scheduled for RFF surgery between 2013 and 2018 showed an insufficient vascular supply according to the Allen test, which was confirmed by digital subtraction angiography (DSA).
- Immunohistochemical expression levels of cyclin D1 and CREPT reflect the course and prognosis in oral precancerous lesions and squamous cell carcinomaby Y.J. Siril, A. Kouketsu, H. Saito, T. Takahashi, H. Kumamoto on 07/04/2021 at 12:00 am
Cyclin D1 is the most essential progressive regulator of the cell cycle, and its transcription is enhanced by CREPT (cell cycle-related and expression-elevated protein in tumour). These molecules regulate cell growth, and their aberrant expression can cause malignant transformation. In this study, the expression of these molecules was explored to investigate the molecular alterations in oral precancerous lesions and squamous cell carcinoma. Cyclin D1 and CREPT expression was examined immunohistochemically in tissue specimens from 55 patients with oral epithelial precursor lesions (OEPLs) and 84 patients with oral squamous cell carcinoma (OSCC).
- Study on the lateral pterygoid muscle status after artificial temporomandibular joint replacementby Y.Q. Zhong, Q. Sun, D.M. He, L.X. Zou, C. Lu on 03/04/2021 at 12:00 am
The purpose of this study was to explore the status of the lateral pterygoid muscle (LPM) after detachment in artificial temporomandibular joint replacement (TJR) surgery. Patient clinical and computed tomography imaging data were collected before and after unilateral artificial TJR with LPM detachment. The volume of the LPM on the operated and unoperated sides was measured before and after surgery (at 1, 3, 6, 12 months) using ProPlan CMF 3.0 software. The volumes of the LPM on both sides, the patient’s mandibular movements, quality of life (QoL), and pain and diet scores (visual analogue scales) were evaluated and compared at the different follow-up stages.
- Lymphovascular invasion as a prognostic tool for oral squamous cell carcinoma: a comprehensive reviewby M. Mascitti, L. Togni, V.C.A. Caponio, K. Zhurakivska, M.E. Bizzoca, M. Contaldo, R. Serpico, L. Lo Muzio, A. Santarelli on 01/04/2021 at 12:00 am
Oral cancer is the most common malignancy of the head and neck region, characterized by a poor prognosis. Novel prognostic markers are needed to better stratify these patients. Lymphovascular invasion (LVI) has been included in the eighth edition of the AJCC Cancer Staging Manual as an additional prognostic factor, but its influence on the recurrence risk and lymph node metastasis is relatively understudied. This is a comprehensive review of the literature on the clinical and prognostic role of LVI in oral cancer.
- Technique to manage intraoperative cuff leak from damaged endotracheal tube pilot balloonby D. Hao, J.J. Johnson, S.S. Patel, C.A. Liu on 29/03/2021 at 12:00 am
We report a technique that was utilized to manage an intraoperative airway complication occurring during orthognathic surgery wherein the endotracheal tube pilot balloon was inadvertently damaged during the procedure. Readily available operating room materials were used to safely and rapidly repair the damaged endotracheal tube pilot balloon. This allowed the perioperative team to avoid emergent endotracheal tube exchange and potential airway complications.
- Use of the temporal extension of the buccal fat pad for closure of oro-antral communicationsby N. Rathod, B. Khobaragade, K. Ganesan on 24/03/2021 at 12:00 am
Oro-antral communications/fistulae (OAC/OAF) can cause significant patient morbidity, with treatment for defects greater than 5mm in size requiring surgical reconstruction. This technical note evaluates the effectiveness, and proposes the use of, the temporal extension of the buccal fat pad (TEBFP) for the closure of large OAC. The TEBFP can be an effective means of large OAC closure due to its ease of harvesting, with minimal damage to surrounding structures or aesthetic changes. The use of the TEBFP provides stability, versatility, and tension-free closure, with minimal postoperative complications.
- A population-based study of the epidemiology of oral squamous cell carcinoma in the Netherlands 1989–2018, with emphasis on young adultsby A.A.H. Al-Jamaei, B.A.C. van Dijk, M.N. Helder, T. Forouzanfar, C.R. Leemans, J.G.A.M de Visscher on 24/03/2021 at 12:00 am
There has been an increasing trend in oral squamous cell carcinoma (OSCC) in patients under 45 years of age. The aim of this study was to evaluate the burden of OSCC in the Netherlands between 1989 and 2018 among young adults (age 20–34 years) when compared to adults (age 35–44 years), and to describe the burden in older groups as well, utilizing cancer registry data to characterize incidence patterns by age, sex, and risk factors. A total of 18,963 cases of OSCC were reported. The overall incidence rate, as measured by annual percentage change (APC), increased significantly from 1989 to 2010 by 1.3% per year (95% confidence interval (CI) 0.9–1.7%) but decreased thereafter by −0.9% (95% CI −2.5% to 0.7%).
- The efficacy of intra-articular injectable platelet-rich fibrin application in the management of Wilkes stage III temporomandibular joint internal derangementby D. Torul, B. Cezairli, K. Kahveci on 23/03/2021 at 12:00 am
The aim of this retrospective study was to compare the effectiveness of hyaluronic acid (HA) and injectable platelet-rich fibrin (i-PRF) in the management of Wilkes stage III internal derangement, and to evaluate the biosupplementation capacity of i-PRF. The records of all 54 relevant patients with Wilkes stage III internal derangement confirmed by magnetic resonance imaging and treated with arthrocentesis alone or in combination with HA or i-PRF were selected. The outcome variables were pain intensity at rest (VASr) and in function (VASf), evaluated with a visual analogue scale, and maximum mouth opening (MMO), evaluated in millimetres; assessments were made preoperatively, immediately after the procedure, and at 1 week, 1 month, and 3 months postoperatively.
- Extracraniofacial anomalies in Treacher Collins syndrome: A multicentre study of 248 patientsby Caroline A. Beaumont, David J. Dunaway, Bonnie L. Padwa, Chris Forrest, Maarten J. Koudstaal, Cornelia J.J.M. Caron on 19/03/2021 at 12:00 am
Treacher Collins syndrome (TCS) is a congenital malformation of the craniofacial structures derived from the first and second pharyngeal arches. The craniofacial deformities are well described in the literature. However, little is known about whether there are associated extracraniofacial anomalies. A retrospective study was conducted using data from four craniofacial units. Medical charts were reviewed for the presence and type of extracraniofacial anomalies, as well as age at diagnosis. A possible correlation between the severity of the phenotype and the presence of extracraniofacial anomalies was assessed using the Hayashi classification.
- Three-dimensional morphological analysis of neocondyle bone growth after fibula free flap reconstructionby Y. Yu, H.Y. Soh, S. Bai, W.-B. Zhang, Y. Wang, X. Peng on 19/03/2021 at 12:00 am
The aim of this retrospective study was to verify the three-dimensional morphological change in neocondyle bone growth after fibula free flap (FFF) reconstruction. The independent variables were age, sex, and diagnosis. Outcome variables included the direction and volume of neocondyle bone growth, and the time to a stable neocondyle following bone growth. The outcome variables were measured on postoperative computed tomography scans using iPlan 3.0. Of the 35 patients included, 25 showed neocondyle bone growth.
- Ocular and adnexal anomalies in craniofacial microsomia: Type and prevalence in a multicentre cohort studyby W. Rooijers, R.W. Renkema, S.E. Loudon, T. Khoshnaw, B.L. Padwa, D.J. Dunaway, M.J. Koudstaal, C.R. Forrest, C.J.J.M. Caron on 19/03/2021 at 12:00 am
The aim of this multicentre retrospective cohort study was to describe and categorize the types of ocular and adnexal anomalies seen in patients with craniofacial microsomia (CFM) and to determine their prevalence. In addition, the relationship between the OMENS-Plus and Pruzansky–Kaban classification for each patient and the presence of ocular anomalies was investigated. A total of 881 patients with CFM from four different craniofacial centres were included. Data on ocular anomalies were gathered from the patient charts.
- Malignant transformation of calcifying epithelial odontogenic tumour with solitary pulmonary metastasisby A.S. Tabaksert, G. Jenkins, P. Sloan, J. Adams on 17/03/2021 at 12:00 am
This report describes the management of a case of calcifying epithelial odontogenic tumour (CEOT) that underwent malignant transformation and metastasized to the lung. The solitary pulmonary metastasis was discovered incidentally on computed tomography (CT) imaging of the neck. It appears that only one previous case with proven pulmonary metastasis has been reported in the literature, which involved multiple pulmonary deposits managed with platinum chemotherapy. The long-term prognosis of metastatic CEOT is therefore unknown.
- New method for quantification of the relative severity and (a)symmetry of isolated metopic synostosisby O.D.M. Kronig, S.A.J. Kronig, H.A. Vrooman, J.F. Veenland, L.N.A. Van Adrichem on 17/03/2021 at 12:00 am
Trigonocephaly is the result of premature fusion of the metopic suture and its severity can vary widely. However, there is no gold standard for quantification of the severity. This study was performed to quantify severity using the Utrecht Cranial Shape Quantifier (UCSQ) and to assess forehead symmetry. Nineteen preoperative non-syndromic trigonocephaly patients (age ≤1 year) were included for the analysis of severity and symmetry. Severity according to the UCSQ was based on the following combined variables: forehead width and relative skull elongation.
- Decreased recurrence of symptoms in oral lichen planus with intralesional injection of hyaluronic acid and triamcinoloneby F. Agha-Hosseini, F. Atyabi, K. Akbari, M.-S. Moosavi on 16/03/2021 at 12:00 am
Oral lichen planus (OLP) is a chronic non-infectious, inflammatory, immunological disease. In contrast to skin lesions, which are often self-limiting, oral lesions rarely heal on their own and can be resistant to local and systemic treatments. In this clinical trial, hyaluronic acid (HA) was mixed with triamcinolone for intralesional injection to reduce side effects in the treatment of OLP. This randomized clinical trial with a split-mouth design was performed on 28 patients with OLP. The mouth was divided randomly into two sides: a test side, which received HA combined with triamcinolone, and a control side, which received triamcinolone alone.
- Squamous cell carcinoma of the tongue in 5-year-old girl with dyskeratosis congenitaby Kim JH, Kim CS on 15/03/2021 at 12:00 am
Dyskeratosis congenita is a rare inherited bone marrow failure syndrome with three distinct clinical features: nail dystrophy, reticular skin pigmentation, and oral leukoplakia. The case of a 5-year-old female patient diagnosed with squamous cell carcinoma of the tongue is reported here. An autosomal dominant type 3 TINF2 mutation subsequently confirmed the diagnosis of dyskeratosis congenita. The traditional tongue cancer treatment was adapted for this young patient. While the tongue cancer lesions and leukoplakia were removed, the deep margins were minimized to preserve the tongue muscles and flap surgery was avoided.
- First bite syndrome after parotidectomy: a single-centre experienceby K. Lammek, D. Tretiakow, A. Skorek on 14/03/2021 at 12:00 am
The aim of this study was to investigate the prevalence of first bite syndrome (FBS) among post-parotidectomy patients and to analyse the risk factors for its occurrence. The study involved 111 adult patients operated for benign parotid tumours. After surgery, the participants were asked to assess the presence of food-related pain and the nature of the pain. Participants also answered questions on complications after parotidectomy. FBS was found in seven patients (6.3%). Sex (P=0.036) and age (P=0.002) differed significantly between patients with and without FBS.
- Could implant position influence the peri-implant parameters in edentulous mandibles of diabetics rehabilitated with overdentures? A split-mouth randomized studyby A. Conte, B. Ghiraldini, P.H.F. Denófrio, F.V. Ribeiro, S.P. Pimentel, M.Z. Casati, M.G. Corrêa, F.R. Cirano on 11/03/2021 at 12:00 am
This randomized controlled trial assessed the impact of crestal level position of implants installed in type 2 diabetes mellitus (T2DM) patients rehabilitated with overdentures. Twenty-two mandibular edentulous T2DM patients were submitted to implant placement for retention of an overdenture. By means of a split-mouth design, two implants were installed: one at supracrestal level (SL) and one at crestal level (CL). Clinical, immunoenzymatic and tomographic analyses were performed at prosthesis placement (baseline) and after 6, 12 and 24 months following implant loading.
- Hearing changes after temporomandibular joint arthroscopy: a prospective studyby D.F. Ângelo, A. Moreira, D. Sanz, R. São João on 10/03/2021 at 12:00 am
Temporomandibular Joint (TMJ) arthroscopy is considered an effective and safe minimally invasive surgical approach. While the long-term outcomes of arthroscopy tend to be positive and free of secondary effects, patients occasionally complain about their hearing following the treatment. The aim of this prospective study was to investigate possible hearing changes associated with TMJ arthroscopy. Pure-tone audiograms were performed in patients two weeks before TMJ arthroscopy and repeated six weeks after intervention.
- Volume and location of the defect as predictors of speech outcome after glossectomy: correlation with a classificationby S. Bhattacharya, K. Thankappan, S.V. Sukumaran, M. Mayadevi, D. Balasubramanian, S. Iyer on 10/03/2021 at 12:00 am
The evaluation of speech outcomes after resection and reconstruction of the oral tongue remains largely unsystematic. A cross-sectional study was performed to analyse the speech outcomes of patients who underwent curative treatment with appropriate reconstruction. Sixty-nine patients were assessed for speech intelligibility and phonetics using a validated speech intelligibility assessment tool in the local language. Volume defects were classified as class I (less than one third), II (one third to half), III (half to two-thirds), or IV (two-thirds to total glossectomy).
- Real-time screening tool for identifying post-traumatic stress disorder in facial trauma patients in a UK maxillofacial trauma clinicby K. Howson, E. Yeung, L. Rayner, K. Fan on 09/03/2021 at 12:00 am
Post-traumatic stress disorder (PTSD) is a distressing consequence of a traumatic event associated with an increased suicide risk and reduced quality of life. Surgeons often have low confidence in identifying psychological problems. The prevalence of PTSD following facial trauma ranges from 23% to 41%. This highlights the importance of identifying and managing at-risk patients to optimize both mental and physical recovery. IMPARTS (Integrating Mental and Physical healthcare: Research, Training and Services) provides electronic screening tools to guide the non-mental health clinician in the ‘real-time’ identification, documentation, and management of potential mental health problems.
- Use of a ‘low and short’ medial cut limits sagittal ramus osteotomy interferencesby J.C. Posnick, B.E. Kinard on 09/03/2021 at 12:00 am
The traditional ‘high and short’ medial cut of the sagittal ramus osteotomy (Hunsuck modification) is a frequent cause of lingual plate interferences in patients undergoing mandibular yaw or cant corrections. We describe how the modified ‘low and short’ medial cut of the sagittal ramus osteotomy reduces lingual plate interferences with improved passive alignment of the osteotomy segments.
- Intraoperative real-time navigation and intraoperative three-dimensional imaging for patient-specific total temporomandibular joint replacementby M.-T. Neuhaus, A.-N. Zeller, P. Jehn, B. Lethaus, N.-C. Gellrich, R.M. Zimmerer on 08/03/2021 at 12:00 am
Customized solutions for replacement of the temporomandibular joint (TMJ) along with surgical guides enable precise and fast transfer of the virtual plan to the patient. However, these guides lack information on screw vectors and length, and well-defined borders for bony resections towards the medial skull base. This retrospective study was performed to investigate the feasibility and benefit of real-time navigation and intraoperative three-dimensional imaging during total TMJ replacement (TJR), as well as patient clinical outcomes.
- Response to “Major head and neck surgery as a risk factor for postoperative atrial fibrillation”by A.M. Weyh, C.S. Elayi, J.N. Catanzaro, K. Esmail, M. Yekikian, A.M. Bunnell, R.P. Fernandes on 07/03/2021 at 12:00 am
We are writing in response to the Letter to the Editor regarding our manuscript titled “Head and neck surgery is a risk factor for atrial fibrillation: incidence and outcomes”. We thank the author for their comments.
- Arthroscopic versus open disc repositioning and suturing techniques for the treatment of temporomandibular joint anterior disc displacement: 3-year follow-up studyby A. Abdelrehem, Y.-K. Hu, C. Yang, J.-S. Zheng, P. Shen, Q.-C. Shen on 06/03/2021 at 12:00 am
The aim of this study was to evaluate the outcomes of temporomandibular joint (TMJ) arthroscopic and open disc repositioning procedures in the management of anterior disc displacement (ADD). All consecutive patients treated with arthroscopic (group I) or open (group II) disc repositioning between April 2014 and August 2018 were included prospectively. The patients were assessed clinically (1, 3, 6, 12, 24, and 36 months postoperative) and with magnetic resonance imaging (MRI). The statistical analysis was performed using IBM SPSS Statistics v.22.0; P < 0.05 was considered significant.
- Effect of computer-assisted design and manufacturing cutting and drilling guides accompanied with pre-bent titanium plates on the correction of skeletal class II malocclusion: a randomized controlled trialby S. Liu, J. Li, C. Xu, H. Zhou, C. Liao, W. Fei, E. Luo on 05/03/2021 at 12:00 am
This study was performed to assess the effect of correcting skeletal class II malocclusion based on the application of computer-assisted design and manufacturing (CAD/CAM) cutting and drilling guides accompanied with pre-bent titanium plates. Fifty patients with skeletal class II malocclusion were recruited into this prospective randomized controlled clinical trial and assigned to two groups. Patients underwent bilateral sagittal split ramus osteotomy directed by CAD/CAM cutting and drilling guides accompanied with pre-bent titanium plates (group A) or CAD/CAM splints (group B).
- Detection of facial landmarks by a convolutional neural network in patients with oral and maxillofacial diseaseby M. Ding, Y. Kang, Z. Yuan, X. Shan, Z. Cai on 04/03/2021 at 12:00 am
Facial nerve dysfunction is common in patients with Bell’s palsy, trauma, tumour, or iatrogenic injuries. Imaging assessment is the most convenient method for patients and their treating physician. With developments in artificial intelligence (AI), manual work will be replaced. In this study, a database of facial images of patients with oral and maxillofacial diseases was set up to develop a facial nerve functional assessment system based on AI. This database was then used to evaluate the accuracy of a state-of-the-art algorithm for facial landmark detection named ‘HRNet’.
- Complications after different methods for fixation of mandibular angle fractures: network meta-analysis of randomized controlled trialsby S.G.M. Falci, G.M. de Souza, I.A. Fernandes, E.L. Galvão, E.A. Al-Moraissi on 04/03/2021 at 12:00 am
The aim of this review was to compare mandibular angle fracture fixation methods that were evaluated through randomized clinical trials considering postoperative complications. Additionally, different treatment methods were ranked based on their performance. A systematic review was performed based on the Cochrane and PRISMA guidelines. The quality of evidence and network meta-analysis were conducted using the GRADE tool and R software, respectively. Four databases were searched, and the papers were selected based on the PICOS strategy.
- Use of facial vein graft with vascularized composite auricular helical rim flap for alar rim defectsby L. Zheng, S. Liu, X. Lv, Y. Shi on 04/03/2021 at 12:00 am
Nasal alar defects lead to facial disfigurement, and nasal ala reconstruction is an important treatment option. The vascularized composite auricular flap based on the superficial temporal artery is an ideal option for a full-thickness nasal alar defect. However, the pedicle length and the discrepancy in artery diameter between the recipient vessel and flap pedicle continue to be major problems for free auricular composite tissue transfer. Considering that the angular artery is occasionally absent and the course of the infraorbital segment of the facial vein is constant, there are often no suitable vessels around the recipient site for anastomoses to the short pedicle of the flap.
- Use of a stackable surgical guide to improve the accuracy of the lateral wall approach for sinus grafting in the presence of a sinus septumby K.N. Teixeira, M.A. Sakurada, A.G. Philippi, T.M.S.V. Gonçalves on 04/03/2021 at 12:00 am
The identification and management of interfering maxillary sinus septa is essential to anticipate and prevent membrane perforation and other complications during sinus grafting. A computer-guided sinus approach based on a new magnetic stackable surgical guide was planned, to transfer the exact position of the septum and optimize the positioning of the lateral access windows. This technique reduces the risk of sinus membrane injury, thereby increasing the safety and efficacy of the procedure.
- A study of unfavorable splits in the sagittal ramus osteotomy with a short lingual cutby N. Tomomatsu, N. Takahara, K. Nakakuki, A. Kimura, Y. Kurasawa, M. Terauchi, T. Yoda on 04/03/2021 at 12:00 am
In the bilateral sagittal split osteotomy, a short lingual cut is made on the medial side of the ramus; however, in some cases, a true fracture occurs on the buccal side of the ramus. The purpose of this study was to evaluate the relationship between the splitting pattern of the mandible and the form of the mandible, the surgical technique used, and the postoperative occurrence of relapse after ‘unfavorable’ splits. The investigation examined 143 patients in whom a short lingual cut was attempted.
- Clinicopathologic factors associated with malignant transformation of oral leukoplakias: a retrospective cohort studyby F. Jäwert, H. Pettersson, E. Jagefeldt, E. Holmberg, G. Kjeller, J. Öhman on 02/03/2021 at 12:00 am
It is clinically challenging to identify oral leukoplakias that have a high risk of undergoing malignant transformation. The aim of this retrospective study was to elucidate the associations between malignant transformation of oral leukoplakias and various clinicopathologic factors. Patients with a diagnosis of clinical oral leukoplakia, verified through histopathologic examination and with access to digital images of the lesion, were retrospectively included for the period 2003–2013. Using the clinical images, all lesions were re-evaluated regarding diagnosis and clinical subtype.
- Surgical management of the odontogenic keratocyst: A 20-year experienceby S. Mohanty, J. Dabas, A. Verma, S. Gupta, A.B. Urs, S. Hemavathy on 02/03/2021 at 12:00 am
The objective of this study was to describe the authors’ long-term experience with the management of odontogenic keratocysts (OKCs). All OKC cases treated at the study centre between 1999 and 2015, with a minimum of 5 years of follow-up by December 2019, were reviewed retrospectively. Operative procedures including decompression/marsupialization, enucleation (E), E+Carnoy’s solution (CS), E+CS+peripheral ostectomy (PO), and resection were assessed for complete resolution, partial resolution, and recurrence rates.
