- Detection of facial landmarks by a convolutional neural network in patients with oral and maxillofacial diseaseby Mengkun Ding, Yifan Kang, Zhihang Yuan, Xiaofeng Shan, Zhigang 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.

The purpose of this study was to investigate the prognostic value of prognostic nutritional index (PNI) in oral squamous cell carcinoma (OSCC) patients and to undertake a comparative evaluation of the prognostic value of comparing PNI, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) in terms of prognostic utility. A retrospective study was conducted involving 203 consecutive patients with OSCC who were treated with radical surgery with curative intent.
- Major head and neck surgery as a risk factor for postoperative atrial fibrillationby Akilesh Ramasamy on 01/03/2021 at 12:00 am
The study by Weyh et al.1 on the risk of atrial fibrillation (AF) in major head and neck surgeries is an interesting exploratory analysis of retrospective data. The interpretation of retrospective data to associate a complex multifactorial phenomenon like AF to major head and neck surgery has severe limitations. I wish to share some observations about the same, in reference to the data presented.

- Technique for modified transantral orbital decompression for improved cosmesis in stable thyroid eye diseaseby J.E. Lu, M. Bergman, M.A. Burnstine on 28/02/2021 at 12:00 am
Functional and aesthetic rehabilitation of exophthalmos in stable thyroid eye disease (TED) can be achieved with a variety of surgical approaches. This article illustrates modifications of the classic transantral technique to provide a graded orbital decompression and achieve improved cosmesis. A retrospective chart review was performed of stable TED patients who elected to undergo the modified transantral decompression; illustrative cases are described. This modified transantral orbital decompression allows for graded orbital decompression surgery, adding to the range of treatment options for stable TED patients.
- Variables associated with stability after Le Fort I osteotomy for skeletal class III malocclusionby C.C. Lee, O. Xhori, R.J. Tannyhill, L.B. Kaban, Z.S. Peacock on 28/02/2021 at 12:00 am
The purpose of this study was to assess skeletal stability and predictors of relapse in patients undergoing an isolated Le Fort I osteotomy. A retrospective cohort study of 92 subjects undergoing Le Fort I osteotomy for Class III malocclusion was implemented. Predictor variables were demographic and perioperative factors. The primary outcome variable was postoperative skeletal position with relapse defined as >2mm sagittal and/or vertical change at A-point on serial lateral cephalograms at immediate postoperative, 1 year, and latest follow-up time points.
- Response to Letter to the Editor “Ectomesenchymal chondromyxoid tumour on the lateral border of the tongue: some historical and clinical considerations”by K. Sakurai, K. Nakamori, M. Yamazaki, J.-i. Tanuma on 27/02/2021 at 12:00 am

- Measurement of hydraulic pressure on the sinus membrane for safer control during transcrestal sinus liftingby J.H. Ro, J.H. Moon, M.C. Cheon, C.J. Park on 26/02/2021 at 12:00 am
The aim of this study was to determine the hydraulic pressures necessary to separate and lift the sinus membrane from the sinus floor in order to ensure a more controlled and safer hydraulic transcrestal sinus lifting surgery and prevent sinus membrane perforation. A flow-regulating hydrodynamic device with a pressure sensor was used in nine patients. The hydraulic pressure was found to increase steadily up to a mean peak of 25.0±13.0kPa, which is comparable to the medium suction power of ordinary vacuum cleaners.
- Staged autogenous calvarial bone grafting and dental implants placement in the management of oligodontia: a retrospective study of 20 patients over a 12-year periodby A. Laventure, G. Raoul, R. Nicot, J. Ferri, L. Lauwers on 26/02/2021 at 12:00 am
Oligodontia demands multidisciplinary management due to its repercussions on dentofacial growth. To place implants to realize implant-borne fixed denture, preimplant surgery may be necessary if bone volumes are insufficient. Our aim was to assess bone increase following autogenic bone grafting and to discuss prosthetic options. Twenty patients followed for oligodontia, who underwent bone grafting, were treated from 2008 to 2019. Transversal and vertical bone levels were measured pre- and postoperatively to assess alveolar ridge augmentation.
- Immediate implant placement in edentulous oral cancer patients: a long-term retrospective analysis of 207 patientsby J.G.H. Wetzels, G.J. Meijer, A.F.J. de Haan, M.A.W. Merkx, C.M. Speksnijder on 25/02/2021 at 12:00 am
Although the functional benefits of implants in the rehabilitation of edentulous cancer patients are well-known, most studies report on postponed implant placement. The outcome of immediate implant placement regarding successful rehabilitation, implant loading and survival is unclear. Two hundred and seven edentulous oral cancer patients that received implants during ablative surgery at the Radboud University Medical Centre between 2000 and 2011 were included. Data regarding the oncological treatment, implant placement, follow-up and prosthodontic rehabilitation were recorded retrospectively with a follow-up period of 5–17 years.
- Outcomes of osseointegrated implants in patients with benign and malignant pathologies of the head and neck: a 10-year single-centre studyby D. Khadembaschi, S.C. Borgna, N. Beech, M.D. Batstone on 25/02/2021 at 12:00 am
The surgical management of head and neck pathologies involving the maxilla and mandible results in significant functional and aesthetic deficits, and ultimately reduced quality of life. Composite free flaps used for reconstruction address many of these deficits and create a foundation for the use of osseointegrated implants to support prosthetic replacement of the dentition. There are few comparative studies examining outcomes of implants in native and reconstructed bone in head and neck cancer patients.
- Saliva flow rates and clinical characteristics of patients with burning mouth syndrome: A case–control studyby S. Werfalli, M. Drangsholt, J.M. Johnsen, S.K. Jeffrey, S. Dakhil, R.B. Presland, L. LeResche on 25/02/2021 at 12:00 am
Burning mouth syndrome (BMS) is a chronic pain condition that most commonly affects postmenopausal women older than 50 years of age. Xerostomia is a common complaint among BMS patients. However, previous studies showed inconsistent findings regarding saliva flow rate reduction. This study examined saliva flow rates, degree of mucosal hydration, xerostomia, and clinical characteristics in BMS patients compared with healthy controls. Unstimulated whole saliva (USWS) was collected through passive drooling; residual mucosal saliva (RMS) was collected using filter paper strips.
- Is there a difference in treatment effect of different intra-articular drugs for temporomandibular joint osteoarthritis? A systematic review of randomized controlled trialsby A. Liapaki, J.R. Thamm, S. Ha, J.L.G.C. Monteiro, J.P. McCain, M.J. Troulis, F.P.S. Guastaldi on 25/02/2021 at 12:00 am
A systematic review based on the PRISMA guidelines was conducted to investigate and compare treatment with hyaluronic acid (HA), corticosteroids, and blood products in patients with temporomandibular joint osteoarthritis (TMJOA). The MEDLINE/PubMed, Embase, and Cochrane Library databases were searched for articles published until September 25, 2019. Articles met the inclusion criteria if they reported patients with TMJOA, a comparison group, and a follow-up period of at least 6 months. The mean and standard deviation for TMJ pain and maximum mouth opening (MMO) were reported.
- Trichilemmal carcinoma of the scalpby J. Usseglio, E. Pagès, A. Guyot, J. Laloze, J. Ferri on 25/02/2021 at 12:00 am
This report describes the case of an 86-year-old male who presented with a large scalp tumour. Imaging revealed a large vertex mass, without intracranial extension, and multiple nodular subcapsular hepatic lesions suspected to be secondary in nature. Surgical resection was performed. Pathological examination revealed an adnexal carcinoma of follicular origin, thus a trichilemmal carcinoma. Controlled wound healing (budding of the diploë) was completely successful within 12 months. The patient refused the assessment and treatment of his metastases.
- The impact of a surgery-first approach on oral health-related quality of lifeby S. Vongkamolchoon, S.P. Sinha, Y.-F. Liao, Y.-R. Chen, C.S. Huang on 25/02/2021 at 12:00 am
Orthognathic surgery using a surgery-first approach (SFA) has been shown to result in better quality of life (QoL) throughout the treatment duration; however, the effects of gender, age and type of dentofacial deformity on SFA-related QoL remain unknown. In total, 228 consecutive patients underwent SFA for correction of dentofacial deformities (skeletal class III, bimaxillary protrusion and facial asymmetry). We assessed their QoL before surgery and at 1, 6 and 12 months after surgery using the Orthognathic Quality of Life Questionnaire (OQLQ).
- Do sex hormone imbalances contribute to idiopathic condylar resorption?by M. Yuan, Q. Xie, P. Shen, C. Yang on 23/02/2021 at 12:00 am
Idiopathic condylar resorption (ICR) is an aggressive form of temporomandibular joint disease that most frequently presents in adolescent girls during the pubertal growth spurt. Although numerous studies have indicated that the etiopathogenesis of ICR may be related to estrogen deficiency, the decisive role of estrogens remains controversial, and other sex hormone disturbances have not yet been investigated in this regard. Therefore, the aim of this study was to ascertain the role of serum estrogen levels and also the roles of other sex hormones in the pathogenesis of ICR.
- Short implants (≤6mm) as an alternative treatment option to maxillary sinus liftby P. Carosi, C. Lorenzi, F. Lio, M. Laureti, N. Ferrigno, C. Arcuri on 23/02/2021 at 12:00 am
The aim of this systematic review was to evaluate survival rate of short dental implants placed in the posterior area of the maxilla. The electronic literature search of studies published between January 1, 2010 and February 29, 2020 was performed using specific word combinations. The outcome was to meta-analyse the implant survival rate (ISR). The search generated 238 potential studies. After screening procedures, only nine randomized controlled trials fulfilled the inclusion criteria and were selected for qualitative and quantitative analysis.
- Variation between natural head orientation and Frankfort horizontal planes in orthognathic surgery patients: 187 consecutive casesby F. Hernández-Alfaro, M. Giralt-Hernando, P.J. Brabyn, O.L. Haas, A. Valls-Ontañón on 22/02/2021 at 12:00 am
The purpose of this study was to assess the relationship between the Frankfort horizontal (FH) and natural head orientation (NHO), their correlation between patients’ malocclusion, and the impact of counterclockwise rotation (CCW) on the FH-NHO angle variation after orthognathic surgery. An evaluation of 187 consecutive patients was performed at the Maxillofacial Institute (Teknon Medical Center, Barcelona). FH-NHO° was measured pre- and postoperatively at 1 and 12 months, after three-dimensional (3D) superimposition using a software (Dolphin®).
- Short-term use of an exposed polypropylene barrier in the preservation of alveolar bone after extraction: randomized clinical trialby C.C.V. dos Santos, K.R. Tonini, M.A.A. Silva, P.S.P. de Carvalho, D. Ponzoni on 22/02/2021 at 12:00 am
This study was performed to evaluate the short-term preservation of alveolar bone volume with or without a polypropylene barrier and exposure of the area after extractions. Thirty posterior tooth extraction sockets were distributed randomly to a control group (n=15; extraction and suture) and a barrier group (n=15; extraction, barrier, and suture). All sutures and barriers were removed 10 days postoperatively. Cone beam computed tomography scans taken with the aid of a tomographic guide were obtained preoperatively, immediately postoperative, and at 120 days postoperative.
- Submandibular gland obstruction caused by an implant-retained lower denture: a report of three casesby E.H. van der Meij, L.J. Beumer, A. Matthews-Brzozowski, J.G.A.M. de Visscher on 22/02/2021 at 12:00 am
The aim of this study was to investigate the role of lower dentures in the development of distally located stenoses of Wharton’s duct and to further identify contributing factors to this mechanism.In a database of 352 patients with submandibular gland obstruction, three patients with four obstructed glands with stenosis of the ostium of Wharton’s duct suspected to be caused by a lower denture were identified and further retrospectively analysed by studying medical records, operation reports, and clinical photographs.
- INTRAORAL ANASTOMOSIS IN MAXILLARY MICROVASCULAR RECONSTRUCTION AFTER ONCOLOGICAL EXCISIONby A. Bueno de Vicente, F. Almeida, J.A. Nuñez, M. Picon, J. Acero on 19/02/2021 at 12:00 am
Microvascular anastomosis using an intraoral approach can avoid unnecessary external incisions thus improving patient satisfaction. Furthermore, in case of short pedicle flaps, the lack of proximity of the recipient vessels can be a problem in microvascular reconstruction of the midface. We present our experience in six patients treated for tumours affecting the midface and reconstructed with microvascular flaps through anastomosis to the intraoral aspect of the facial vessels, with the aim of reviewing the use of this technique.
- The effect of zirconia and titanium surfaces on biofilm formation and on host-derived immunological parametersby K. Kniha, N. Heussen, A. Modabber, F. Hölzle, S.C. Möhlhenrich on 19/02/2021 at 12:00 am
The aim of this study was to analyse the effect of zirconia and titanium surfaces on biofilm formation and host-derived parameters. Studies comparing zirconia and titanium surfaces were selected up to September 1, 2019. The outcome measures were surface roughness, contact angle, bacterial count, bacterial adherence, biofilm thickness, bacterial distribution, and specifically investigated biofilm and specific host-derived immunological parameters. Random-effects meta-analyses of in vitro and in vivo studies were conducted.

The objective of this study was to investigate the accuracy of fine needle aspiration cytology (FNAC) and biopsy for the clinical diagnosis of minor salivary gland tumours (MSGTs). This retrospective study of 32 MSGT cases was conducted over a 5-year period. Clinical features including age, sex, and location of the tumour were obtained from the patient clinical records. All cases were also assessed histologically according to the 2017 World Health Organization Classification of Head and Neck Tumours.
- Quantitative description of masseter muscle involvement in craniofacial microsomiaby W. Han, X. Yang, X. Chen, W. Mooi, Z.M. Aung, M. Sun, H. Xu, Y. Zhang, G. Chai on 18/02/2021 at 12:00 am
Masseter deficits are common in craniofacial microsomia (CFM), however studies on masseter muscle involvement are limited. The aim of this study was to describe the morphology and functional involvement of the masseter muscles quantitatively. Ninety-eight patients with CFM who underwent three-dimensional computed tomography and surface electromyography were included. The mean action potential during maximum voluntary contraction in the intercuspal position was recorded. Asymmetry of the compound muscle action potential (ACMAP) was calculated as an indicator of functional involvement.
- Evaluation of facial aesthetics by laypersons in patients undergoing intraoral quadrangular Le Fort II osteotomy compared with conventional Le Fort I osteotomyby J. Cede, A. Graf, J. Zeitlinger, F. Wagner, K. Willinger, C. Klug on 16/02/2021 at 12:00 am
In this study we compared the aesthetic outcome of (1) Le Fort I (LFI) osteotomy and (2) intraoral quadrangular Le Fort II (IQLFII) osteotomy for surgical correction of skeletal class III dysgnathia involving midfacial deficiency. The aim was to investigate whether laypersons see differences in facial changes that occur due to variations of the osteotomy cuts. The patient collectives consisted of 23 patients in each group. Pre- and postoperative photographs were presented in a random sequence to 40 layperson raters.
- Analysis of local invasion and regional spread in malignant sublingual gland tumour: Implications for surgical planningby W. Park, M. Park, K. Choi, Y. Heo, S.Y. Choi, J. Cho, Y.-H. Ko, H.-S. Jeong on 15/02/2021 at 12:00 am
Malignant tumours arising from the sublingual glands are very rare, and the extent and frequency of local invasion or regional spread in malignant sublingual gland tumour (MSLT) has not been fully studied due to the disease rarity. To provide comprehensive features of local and regional spread of MSLT, we reviewed 20 surgical cases for detailed pathological analyses among 26 cases diagnosed as having primary MSLT. Adenoid cystic carcinoma (ACC) was the most common pathological subtype, followed by mucoepidermoid carcinoma.
- Diagnostic yield of sentinel lymph node biopsy in oral squamous cell carcinoma T1/T2-N0: systematic review and meta-analysisby M. Mallo Magariños, M. Suárez Ajuria, X. Marichalar Mendía, Ó.

A systematic search based on PRISMA guidelines, including a computer search with specific keywords, reference list search, and manual search was performed. Relevant articles were selected after three search rounds for final review based on six predefined inclusion criteria, followed by a round of critical appraisal. Eleven publications, including eight randomized controlled trials and three prospective clinical studies, were included in the review.
- Prognostic value of elective neck dissection in adenoid cystic carcinoma of head and neck: a meta-analysis. A call for randomized trials and international consensusby P. Suton, I. Luksic on 15/02/2021 at 12:00 am
Adenoid cystic carcinoma of head and neck (AdCCHN) is an uncommon salivary gland cancer characterized for infrequent neck metastases, and high rate of local and distant recurrence. The aim of this meta-analysis was to analyse the significance of elective neck dissection (END) in terms of overall survival (OS) in patients with AdCCHN. A systematic literature search and meta-analysis was performed. Endpoint assessed by this meta-analysis included 5-year OS (death from any cause). Statistical heterogeneity was assessed using the Cochrane Q test and I2 statistic.
- Vertical bone augmentation and regular implants versus short implants in the vertically deficient posterior mandible: a systematic review and meta-analysis of randomized studiesby H. Terheyden, G.J. Meijer, G.M. Raghoebar on 12/02/2021 at 12:00 am
The aim of this study was to perform a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing the outcomes of short dental implants (≤7mm) versus vertical bone augmentation followed by regular dental implants (>7mm) in the deficient posterior mandible. In total, eight RCTs (six using interpositional sandwich grafting and two using a guided bone regeneration technique) were reported in 17 articles at different time points. In the meta-analysis of the sandwich group, the relative risk (RR) for implant loss at 1year was in favour of short implants (RR 0.41, P=0.02), while no significant difference was found at 3 years (RR 0.65, P=0.43), 5 years (RR 1.08, P=0.86), or 8 years (RR 1.53, P=0.52).
- Odontogenic gingival epithelial hamartoma with a pleomorphic histological appearance: a case report and review of the literatureby H. Sakamoto, S. Fujita, M. Umeda, S. Rokutanda on 11/02/2021 at 12:00 am
Odontogenic gingival epithelial hamartoma (OGEH) is a rare odontogenic epitheliallesion. Distinguishing OGEH from peripheral ameloblastoma can pose a differential diagnostic challenge. We report a case of OGEH affecting the lower gingiva in a 78-year-old male patient. The lesion presented as a large, painless, pedunculated mass with a pleomorphic histological appearance. A diagnosis of OGEH was made after the exclusion of peripheral ameloblastoma and peripheral adenomatoid odontogenic tumour. Previous studies have reported differences in sex and age between patients with OGEH and peripheral ameloblastoma; this suggests that peripheral ameloblastoma is not derived from OGEH.
- Prevalence of early and late oral implant loss among smokers: a nationwide survey in Japanby T. Nagao, J. Fukuta, T. Sugai, H. Kawana, A. Matsuo, S. Hamada, K. Miura, K. Seto on 10/02/2021 at 12:00 am
A cross-sectional, nationwide survey was conducted in Japan to examine the relationship between tobacco smoking and oral diseases including implant failure. A questionnaire survey was sent to designated facilities by post, and 158 answered questions regarding implant loss. Smoking status, number of implant failures, and other related variables were collected from the participating dentists as secondary data. A total of 1966 patients who were treated with dental implants by participating dentists during the survey period were analysed.
- Registration of magnetic resonance and computed tomography images in patients with oral squamous cell carcinoma for three-dimensional virtual planning of mandibular resection and reconstructionby M. Polfliet, M.S. Hendriks, J.-M. Guyader, I. ten Hove, H. Mast, J. Vandemeulebroucke, A. van der Lugt, E.B. Wolvius, S. Klein on 04/02/2021 at 12:00 am
The aim of this study was to evaluate and present an automated method for registration of magnetic resonance imaging (MRI) and computed tomography (CT) or cone beam CT (CBCT) images of the mandibular region for patients with oral squamous cell carcinoma (OSCC). Registered MRI and (CB)CT could facilitate the three-dimensional virtual planning of surgical guides employed for resection and reconstruction in patients with OSCC with mandibular invasion. MRI and (CB)CT images were collected retrospectively from 19 patients.
- Donor site morbidity of composite free flaps in head and neck surgery: a systematic review of the prospective literatureby J. Russell, K. Pateman, M. Batstone on 30/01/2021 at 12:00 am
Composite free flaps represent the cornerstone for the repair of osseous defects in the head and neck. For many patients, there are often multiple defect-suitable donor sites that may be utilised as part of the reconstructive process. Therefore, to optimise patient outcomes, an evidence-based approach to donor site selection is required to maximise quality of life and long-term functionality. A systematic review of the literature was conducted in accordance with PRISMA guidelines to evaluate the evidence for donor site selection based on minimising the associated donor site morbidity and optimising patient functionality postoperative.
- Revisiting straight-line repair in unilateral complete cleft lip: a comparison with rotation-advancement repairby J.H. Ha, Y.T. Koo, S.O. Park, I.-K. Kim, J.-H. Chung, S. Kim on 30/01/2021 at 12:00 am
Rotation-advancement repair (RAR) has been the most widely used technique for unilateral cleft lip repair. We recently used a straight-line repair with medial orbicularis muscle lengthening (SLR-ml) technique, based on the hypothesis that it could minimize the postoperative scar appearance without causing s short-lip deformity when muscle reorientation is performed correctly. A retrospective cohort study was conducted on unilateral complete cleft lip patients who underwent cheiloplasty between 2009 and 2017.
- Three-dimensional measurement of radiographic bone–implant contact lengths of zygomatic implants in zygomatic bone: a retrospective study of 66 implants in 28 patientsby T.-Y. Huang, Y.-J. Hsia, M.-Y. Sung, Y.-T. Wu, P.-C. Hsu on 25/01/2021 at 12:00 am
Zygomatic implant treatment is widely applied for severe maxillary atrophy to help rehabilitate the maxillary dentition. This retrospective study was performed to evaluate the actual radiographic bone–implant contact (rBIC) lengths of zygomatic implants. The records of 28 patients who underwent zygomatic implant surgery and subsequent follow-up examinations between August 2013 and September 2018 in the Department of Oral and Maxillofacial Surgery, Taipei Tzu Chi Hospital were reviewed. The surgeries were performed by a single surgeon using the same treatment protocol.
- Surgical complications related to temporomandibular joint arthroscopy: a prospective analysis of 39 single-portal versus 43 double-portal proceduresby D.F. Ângelo, R.A.D. Araújo, D. Sanz on 22/01/2021 at 12:00 am
Temporomandibular joint (TMJ) arthroscopy is a minimally invasive surgical procedure proposed for diverse TMJ intra-articular disorders. A prospective study was designed with the aim of investigating intraoperative and postoperative surgical complications for single and double-portal TMJ arthroscopy. All interventions were performed by one surgeon with the same surgical protocol. A total of 55 patients were enrolled, resulting in 82 TMJ arthroscopies (28 unilateral and 27 bilateral). A total of 39 single portal (47.57%) and 43 double-portal (52.43%) arthroscopies were performed.
- Distinguishing craniomorphometric characteristics and severity in metopic synostosis patientsby L. Chandler, K.E. Park, O. Allam, M.A. Mozaffari, S. Khetpal, J. Smetona, N. Pourtaheri, X. Lu, J.A. Persing, M. Alperovich on 19/01/2021 at 12:00 am
The decision about which metopic synostosis patients should undergo surgery remains controversial. Multiple measures for radiographic severity have been developed in order to determine the optimal criteria for treatment. The aim of this study was to perform an extensive craniomorphometric analysis of patients who underwent surgery for metopic synostosis to validate and compare the various severity scales developed for this non-syndromic craniosynostosis. A comparative morphometric analysis was performed using computed tomography scans of preoperative metopic synostosis patients (n=167) and normal controls (n=44).
- Nasomaxillary effects of miniscrew-assisted rapid palatal expansion and two surgically assisted rapid palatal expansion approachesby A.S. Jesus, C.B. Oliveira, W.H. Murata, E.S. Gonçales, V.A. Pereira-Filho, A. Santos-Pinto on 18/01/2021 at 12:00 am
This retrospective study was performed to evaluate nasomaxillary changes in 36 patients at an advanced stage of skeletal maturity who underwent miniscrew-assisted rapid palatal expansion (MARPE) or surgically assisted rapid palatal expansion (SARPE) with/without an alar base cinch. Cone beam computed tomography images taken before and after expansion were analysed. Changes in the width of the dental arch (D66S, D66I), maxillary base (MxMol), and nasal floor and nasal cavity in the molar and canine regions (NaFMol, NaFCan, NaCMol, NaCCan) were compared, as well as changes in the choanal aperture (CA) and nasal soft tissue (NW).
- Denosumab for the management of central giant cell granuloma of the jaws—a case seriesby M.A. Pogrel, M. Hossaini-Zadeh on 16/01/2021 at 12:00 am
Denosumab has been suggested as a medical treatment for central giant cell granuloma of the jaws. This study included eight patients, seven female and one male, aged between 19 and 32 years, with biopsy-proven central giant cell granuloma of the mandible. The patients were treated with subcutaneous injections of 120 mg of denosumab in a regime consisting of three injections at weekly intervals followed by five injections at monthly intervals over a 6-month period. They were followed up for between 60 and 71 months clinically and radiographically with panoramic radiographs and cone beam computed tomography scans.
- Surgical resection of clinically benign tumours in the maxillomandibular deep lobe of the parotid gland via sternocleidomastoid muscle–parotid space approachby D.-c. Wang, Z.-p. Sun, X. Peng, Y.-d. Zhao, C.-l. Ni, C. Mao, Y.-x. Guo, C.-b. Guo on 16/01/2021 at 12:00 am
This article reports the surgical resection of clinically benign tumours in the maxillomandibular deep lobe of the parotid gland via sternocleidomastoid muscle–parotid space (SPS) approach. The use of maxillary–mandibular planes to subdivide the deep lobe of the parotid gland in order to establish the tumour location and accessibility is introduced. This approach, which does not raise a skin flap, may preserve the superficial lobe. Ten patients with clinically benign tumours in the maxillomandibular deep lobe of the parotid gland were treated via the SPS approach.
- Longitudinal recovery pattern of neurosensory deficit after Le Fort I osteotomyby A.B. Alolayan, Y.Y. Leung on 13/01/2021 at 12:00 am
The purpose of this study was to investigate the incidence and recovery pattern of neurosensory deficit (NSD) following Le Fort I osteotomy, and to identify the possible risk factors that might contribute to the complication. A prospective longitudinal observational study on the incidence of NSD was conducted on patients who received Le Fort I osteotomy. Subjective and objective standardized neurosensory assessments were performed preoperatively as the baseline, and postoperatively at 2 weeks, 6 weeks, 3 months, 6 months, 12 months, and 24 months.
- Efficient in-house 3D printing of an orthognathic splint for single-jaw casesby W. Mascarenhas, N. Makhoul on 11/01/2021 at 12:00 am
The purpose of this paper is to outline a simple and effective digital protocol for in-house 3D-printing of orthognathic splints for use during single-jaw orthognathic surgery. Using this protocol, an intraoral scanner, and virtual planning software, computer-designed splints were fabricated by a rapid prototyping machine in-house. The protocol was utilized for 35 consecutive patients requiring single-jaw orthognathic surgery between January 2019 and March 2020. The total time from initial scan to splint fabrication for each case was between 5 and 9hours, including 3minutes for scanning of models, 4.5minutes for development of the splint, and 4–8hours for rapid prototyping and post-processing.
