- Bone characteristics in condylar hyperplasia of the temporomandibular joint: a microcomputed tomography, histology, and Raman microspectrometry studyby J.-D. Kün-Darbois, H. Bertin, G. Mouallem, P. Corre, T. Delabarde, D. Chappard on 27/09/2022 at 12:00 am
Unilateral condylar hyperplasia (UCH) of the temporomandibular joint is a progressive deformation of the mandibular condyle of unknown origin. UCH is characterized by excessive growth of the condylar head and neck, leading to an increase in size and volume. The aim of this study was to investigate the characteristics of the bone in patients with UCH using microcomputed tomography (micro-CT), histology, and Raman microspectroscopy. The mandibular condyles of six patients with UCH were analysed using micro-CT, histology, and Raman microspectrometry and imaging, and the results were compared with those obtained for a normal control subject.
- Effectiveness of different treatments for odontogenic keratocyst: a network meta-analysisby E.A. Al-Moraissi, A. Kaur, R.S. Gomez, E. Ellis on 20/09/2022 at 12:00 am
Odontogenic keratocysts (OKC) are benign but aggressive lesions. As there is a lack of well randomized clinical studies assessing the effectiveness of the different treatment options for OKC, a network meta-analysis (NMA) was performed to identify the best treatment option with the lowest recurrence rate. An electronic search was performed following the PRISMA guidelines to identify all clinical studies comparing treatment options against enucleation alone. The outcome variable was recurrence. The predictor variables were treatments.
- Incidence of occult cleft palate on prenatal magnetic resonance images obtained for non-cleft indicationsby C.M. Resnick, A. Paige, S. Jindal, A.M. Gordon, J.A. Estroff on 20/09/2022 at 12:00 am
Prenatal diagnosis of craniofacial anomalies has improved family education and preparedness. Isolated cleft palate, however, remains difficult to identify sonographically. The aim of this study was to investigate the rate of incidental cleft palate identified on fetal magnetic resonance imaging (MRI) following the ultrasound detection of non-cleft abnormalities. This was a retrospective study of pregnant women who had fetal MRI performed between 2003 and 2017. To be included, the woman had to have been referred for fetal imaging for a non-cleft indication, with subsequent identification of an isolated cleft palate on MRI.
- Reply to the Letter concerning “Combination of fluorescence visualization and iodine solution-guided surgery for local control of early tongue cancer”by T. Morikawa on 18/09/2022 at 12:00 am
We wish to thank the authors for their Letter. The aim of our study was to improve the local control rate by using fluorescence visualization,1 and although the authors’ proposal is different from that purpose, we would like to state our thoughts.
- Prediction of nodal metastasis based on intraoral sonographic findings of the primary lesion in early-stage tongue cancerby S. Kawano, T. Hattori, Y. Mikami, T. Chikui, T. Kawazu, T. Sakamoto, Y. Maruse, S. Tanaka, E. Hamada, M. Hiwatashi, Y. Shiraishi, K. Oobu, T. Kiyoshima, S. Nakamura on 17/09/2022 at 12:00 am
The aim of this study was to clarify the correlation between imaging findings obtained using intraoral ultrasonography (US) and pathological findings of tongue cancers, and to examine the predictive value of intraoral US findings with respect to occult nodal metastasis. This was a retrospective study based on the medical records of 123 patients with T1–2N0 tongue cancer. The depth of invasion (DOI) on intraoral US was positively correlated with the pathological invasion depth (PID) (ρ = 0.7080, P < 0.0001).
- Extracapsular dissection with a transparotid facial nerve dissection approach versus partial superficial parotidectomy for benign tumours in the tail of the parotid gland: a single-centre retrospective study of 89 patientsby Zhigang Liu, Bin Wang, Lihong Yang on 17/09/2022 at 12:00 am
The aims of this study were (1) to evaluate the transparotid facial nerve dissection approach (TFND), in which the intraparotid cervicofacial or temporofacial division is identified first through a superficial lobe incision; and (2) to compare extracapsular dissection with a TFND (ECD-TFND) with partial superficial parotidectomy with a retrograde approach (PSP) for benign tumours in the tail of the parotid gland with respect to surgical outcomes. Eighty-nine patients underwent PSP or ECD-TFND for benign tumours in the tail of the parotid gland: 49 were treated surgically with PSP and 40 with ECD-TFND.
- Arthrocentesis versus non-surgical intervention as initial treatment for temporomandibular joint arthralgia: a randomized controlled trial with long-term follow-upby Y.H. Tang, L.M. Vos, A.J. Tuin, J.J.R. Huddleston Slater, B. Gareb, N.B. van Bakelen, F.K.L. Spijkervet on 15/09/2022 at 12:00 am
Arthrocentesis for arthralgia of the temporomandibular joint (TMJ) is often only indicated when conservative, non-surgical interventions have failed. However, performing arthrocentesis as initial therapy may facilitate earlier and better recuperation of the joint. The aim of this study was to assess the efficacy of this therapy with a long-term follow-up. Eighty-four patients were randomly allocated to receive either arthrocentesis as initial treatment (n = 41) or non-surgical intervention (n = 43).
- Risk factors for lower border notching after bilateral mandibular sagittal ramus advancement: three-dimensional evaluationby A. Masson, A. Veyssiere, A. Briant, P. Weill, R. Preud’homme, H. Benateau on 14/09/2022 at 12:00 am
Bilateral sagittal split osteotomy (BSSO) mandibular advancement can cause mandibular lower border notching (MLBN). The objective of this study was to calculate the incidence of MLBN and identify risk factors. This single-centre, retrospective study was performed between January 2018 and November 2020, in the Maxillofacial Surgery Department, Centre Hospitalier Universitaire, Caen. Patients who underwent BSSO advancement and had cone beam computed tomography (CBCT) scans obtained preoperatively, immediately postoperative (within 1 week), and late postoperative (≥1 year) were included.
- An innovative universal protocol for orthognathic surgery three-dimensional virtual simulationby F. Melhem-Elias, B.A.Q. Reis, F.A.C. Afonso, M.D.A. Barretto, M.C.Z. Deboni on 14/09/2022 at 12:00 am
The aim of this technical note is to describe a protocol for three-dimensional virtual simulation of orthognathic surgery that has been designed to be easily implemented, without the need for any special clinical apparatus, software brand, or computed tomography sequence. The protocol comprises innovative concepts and simplified steps for image segmentation, creation of a composite skull, control of the condylar position, and sequencing of bimaxillary surgery. This protocol was applied by the developers in about 2000 cases performed between 2015 and 2022, and has become quite popular among local surgeons.
- Indocyanine green lymphography for early detection of oral cancerby G. Chisci, Guido Gabriele, Paolo Gennaro on 13/09/2022 at 12:00 am
We read with interest the paper by Morikawa et al.1 reporting their study on the role of iodine solution and fluorescence visualization in guided surgery for oral dysplasia.
- Ambulatory sagittal split ramus osteotomy: strategy for enhanced recovery after surgeryby Y. Hattori, H. Uda, A. Niu, K. Yoshimura, Y. Sugawara on 10/09/2022 at 12:00 am
The sagittal split ramus osteotomy (SSRO) has been performed mainly on an inpatient basis because of the duration of anaesthesia and the potential risk of postoperative complications, such as bleeding, pain, nausea, and vomiting. However, advances in both surgical and anaesthetic management have enabled the reduction of these risks and shortened the length of hospital stay. Thus, the SSRO may be feasible even in the ambulatory setting in elective cases. The clinical records of all patients who underwent an outpatient SSRO between August 2011 and September 2020 at Lilla Craniofacial Clinic were reviewed retrospectively.
- Relationships between squamous cell carcinoma antigen and cytokeratin 19 fragment values and renal function in oral cancer patientsby K. Obata, H. Yutori, K. Yoshida, Y. Sakamoto, K. Ono, S. Ibaragi on 09/09/2022 at 12:00 am
Squamous cell carcinoma antigen (SCC-Ag) and cytokeratin 19 fragment (CYFRA) are used to screen and monitor oral cancer patients. However, recent studies have reported that tumour markers become elevated as renal function decreases, regardless of tumour progression. A retrospective study was performed of 423 oral cancer patients who underwent blood testing for these tumour markers and other blood analytes during a 10-year period. The values of SCC-Ag and CYFRA increased significantly with decreasing renal function (P < 0.01), and the values were abnormal at a median 2.6 ng/ml for SCC-Ag and 4.7 ng/ml for CYFRA in the group with estimated glomerular filtration rate (eGFR) values of< 30 ml/min/1.73 m2.
- “Volume and location of the defect as predictors of speech outcome after glossectomy: correlation with a classification”—Would collateral reinnervation improve the outcome?by S. Mishra, V.U.S. Rao, S. Thakur, A. Subash on 08/09/2022 at 12:00 am
We read with great interest the article titled “Volume and location of the defect as predictors of speech outcome after glossectomy: correlation with a classification” by Bhattacharya et al.1 The oral tongue is one of the most common sites of oral cavity malignancy and is a critical organ for speech and swallowing. The functions of the oral part of the tongue include speech and articulation, as well as mastication, oral hygiene, and the oral phase of swallowing.2 The oropharyngeal tongue is important for the pharyngeal phase of swallowing and prevention of aspiration, and hence the repair of the defect post glossectomy becomes crucial in restoring the form and function of the tongue.
- CAD/CAM and conventional reconstruction of the mandibular condyle by fibula free flap: a clinical and radiological evaluationby M. Maurer, J.M. Gottsauner, J.K. Meier, T.E. Reichert, T. Ettl on 07/09/2022 at 12:00 am
The aim of this study was to analyse the radiological and clinical outcomes of condylar reconstruction by fibula free flap (FFF), comparing conventional freehand and CAD/CAM techniques. Fifteen patients (nine CAD/CAM, six freehand) who underwent condylar reconstruction with a FFF were reviewed retrospectively regarding pre- and postoperative computed tomography/cone beam computed tomography scans and clinical function. After surgery, all patients were free of temporomandibular joint pain. Mean postoperative mouth opening was 30.80 mm, with no significant difference between the freehand and CAD/CAM groups.
- Buccal fat pad as a sealant in palatal mucosa tearing: technical noteby F. Hernández-Alfaro, D. Soriano-Martín, G. Molins-Ballabriga, A. Valls-Ontañón on 05/09/2022 at 12:00 am
For patients with a dentofacial deformity undergoing a planned segmentation of the maxilla for the management of a transverse maxillary arch discrepancy, palatal mucosa tearing may occur during sawing or palatal expansion traction, giving rise to an oronasal communication. This technical note describes the covering of a tear in the palatal mucosa using a buccal fat pad (BFP) flap, in the context of maxillary segmentation during Le Fort I osteotomy. Through the limited buccal incision used for the Le Fort I osteotomy, a small incision is made in the right periosteum posteriorly, and a supraperiosteal dissection is performed to access the BFP.

- Prosthetically guided mandibular reconstruction using a fibula free flap: three-dimensional Bologna plate, an alternative to the double-barrel techniqueby A. Tarsitano, F. Ceccariglia, M. Bevini, L. Breschi, P. Felice, C. Marchetti on 26/08/2022 at 12:00 am
The fibula free flap represents the gold standard for mandibular reconstruction. However, when harvested as a single barrel, this flap does not allow the native mandibular height to be restored, which is required for implant-supported dental rehabilitation of the patient. The aim of this study was to present a new design for a patient-specific three-dimensionally printed reconstructive plate (3DBO-PSI) that positions the fibula bone at the height of the resected mandibular alveolar bone while restoring the mandibular profile to ensure a correct morphological outcome.
- A non-invasive method for the assessment of gingival thickness in the aesthetic zone and the concept of the gingival geometric ratio in an Asian populationby R.L.K. Chow, S.L. Lau, Y.Y. Leung, J.K.F. Chow on 24/08/2022 at 12:00 am
The aim of this study was to investigate the gingival thickness and biologic width in the aesthetic zone (maxillary central and lateral incisors) in an Asian population using cone beam computed tomography (CBCT) as a non-invasive measurement method, prior to immediate implant placement. The gingival geometric ratio is introduced as a new parameter for assessing soft tissue stability and hence predicting the aesthetic outcome. The gingival thickness, biologic width category (normal, high, and low crest), and gingival geometric ratio (shape and configuration of the gingival tissues) were assessed for 171 central and 175 lateral incisors on high-resolution CBCT images.
- Diagnostic performance of SPECT–CT imaging in unilateral condylar hyperplasiaby L.H.E. Karssemakers, J.W. Nolte, C. Rehmann, P.G. Raijmakers, A.G. Becking on 22/08/2022 at 12:00 am
Nuclear imaging plays an important role in the diagnostic path of patients with unilateral condylar hyperplasia (UCH). The purpose of this study was to determine the performance of single-photon emission computed tomography–computed tomography (SPECT–CT) in a large group of patients with suspected UCH. This study prospectively included 156 patients with a clinical presentation of progressive mandibular asymmetry. All patients underwent 99 mTc-HDP SPECT–CT and extensive baseline and follow-up documentation.
- Do dental implants facilitate bone invasion in patients with oral squamous cell carcinoma? A case seriesby J. Verstraeten, P.J. Slootweg, V.M. Cuijpers, G.J. Meijer on 22/08/2022 at 12:00 am
Osseointegrated dental implants in the vicinity of oral squamous cell carcinoma (OSCC) will become more common given the increasing popularity of dental implants. Reports and studies of OSCC around dental implants are rare, as is the topic of how to handle OSCC surgically when implants are in contact with the tumour. In view of this uncertainty, a histological study was performed to assess tumour behaviour around implants. The aim was to determine whether an implant facilitates inward growth of the tumour and how this should be taken into account during staging and treatment planning.

The aim of this study was to evaluate the resorption of the iliac bone after maxillary reconstruction with a vascularized free iliac flap. Twenty-seven patients with maxillary defects who underwent maxillary reconstruction with the vascularized free iliac flap between January 2017 and January 2021 were included. Computed tomography (CT) images taken at 1 week, approximately 6 months, and 1 year after the surgery were used for evaluation. The total iliac bone thickness and height, cortical bone thickness, and cancellous bone density were measured in the CT images.
- The role of anterior segmental osteotomies in orthognathic surgery for protrusive faces in a Southeast Asian population: 10-year retrospective data of 51 patients treated in a single centreby C.W. Yong, T.J.H. Sng, B. Quah, C.K.J. Lee, A.A.T. Lim, R.C.W. Wong on 22/08/2022 at 12:00 am
Bimaxillary protrusion is a dentofacial deformity common in the East Asian population. It is often difficult to decide between orthodontic and surgical retraction to treat patients with bimaxillary protrusion, especially if surgery to correct skeletal base discrepancies is also required. The objective of this study was to investigate the treatment outcomes of surgical versus orthodontic retraction in patients with bimaxillary protrusion undergoing orthognathic surgery. A retrospective cohort study was conducted, where the medical records and radiographs of 51 patients with bimaxillary protrusion who had an anterior segmental osteotomy concomitant with orthognathic surgery were examined.
- Long-term prognosis of burning mouth syndrome following treatmentby M.-J. Kim, J.-H. Choi, H.-S. Kho on 20/08/2022 at 12:00 am
The purpose of this study was to evaluate the long-term prognosis of patients with burning mouth syndrome (BMS) after the termination or discontinuation of treatment and to identify the clinical characteristics that might affect that prognosis. Of 769 patients with an oral burning sensation, 202 with primary BMS who had been treated for at least 3 months were included. Among them, 28 patients who responded to the treatment and 25 patients who did not were assigned to responder and non-responder groups, respectively.
- Effects of maxillomandibular advancement on respiratory function and facial aesthetics in obstructive sleep apnoea patients with versus without maxillomandibular deficiencyby N. Zhou, J.P.T.F. Ho, F. Lobbezoo, G. Aarab, N. de Vries, J. de Lange on 20/08/2022 at 12:00 am
The aim of this study was to compare the effects of maxillomandibular advancement (MMA) on respiratory function between obstructive sleep apnoea (OSA) patients with and without maxillomandibular deficiency, and to compare the changes in facial aesthetics after MMA between the two groups. MMA-treated patients who had both baseline and follow-up polysomnography (PSG) data and lateral cephalograms were enrolled in this retrospective study. In addition to PSG and cephalometric data, patient satisfaction with postoperative breathing and facial aesthetics, and overall satisfaction with the treatment were assessed.
- Transmucosal pterygomaxillary disjunction using a piezoelectric device, in the context of the minimally invasive Le Fort I osteotomy protocolby F. Hernández-Alfaro, M. Ghuloom, M. Giralt-Hernando, A. Lázaro-Abdulkarim, A. Valls-Ontañón on 18/08/2022 at 12:00 am
The aim of this study was to assess the accuracy and clinical implications of pterygomaxillary junction (PMJ) disjunction with a transmucosal PMJ osteotomy using a piezoelectric hand-piece device, in the context of Le Fort I osteotomy, by evaluating the level of PMJ disarticulation and the need for bone trimming around the pedicle. An ambidirectional 1-month follow-up cohort study was designed involving consecutive patients undergoing minimally invasive maxillary Le Fort I osteotomy through the twist technique.
- Mandibular morphology and distraction osteogenesis vectors in patients with Robin sequenceby D.W. Duarte, I.J. Fleith, R.C. Pinheiro, M.F. Machado, E.M. Zanin, M.V.M. Collares on 17/08/2022 at 12:00 am
The aims of this cohort study were to compare the mandibular morphology between patients with Robin sequence (RS) and controls, and to examine the effects of mandibular distraction osteogenesis (MDO) using different vectors. Measurements of the mandibles of 80 patients with RS and 46 controls aged< 90 days were made using computed tomography. The data were compared among isolated RS patients (n = 58), syndromic RS patients (n = 22), and controls. Patients with RS exhibited significantly shorter ramus and body lengths and larger symphyseal angles than controls (all P < 0.001).
- Can surgeons rely on growth-related changes to achieve lip height and width symmetry in unilateral complete cleft lip repair?by K. Alkebsi, Y. Abdo, B.M. Abotaleb, K.A. Sakran, Y. Huang, B. Shi on 17/08/2022 at 12:00 am
Surgeons face difficulties achieving simultaneous lip height and width symmetry while repairing unilateral complete cleft lip, so one is often sacrificed at the expense of the other. The aim of this study was to evaluate the effect of growth on lip height and width symmetry, to guide the surgeon to the best decision. The study patients (N = 105) were divided into two groups based on the treatment method: 42 were treated with the modified rotational advancement technique (MRA group) and 63 with the Millard rotation-advancement technique (RA group).
- Use of free flaps with supermicrosurgery for oncological reconstruction of the maxillofacial regionby L. Zheng, X.-M. Lv, Y. Shi, M.-W. Huang, J. Zhang, S.-M. Liu on 17/08/2022 at 12:00 am
Supermicrosurgery involves the dissection and anastomosis of vessels<0.8 mm in diameter with minimal donor site morbidity. This study evaluated the feasibility and outcomes of free flaps using supermicrosurgery to repair oncological defects in the maxillofacial region. Forty-two patients were treated with supermicrosurgery to repair oncological defects in the maxillofacial region between December 2015 and February 2021. The supermicrosurgery technique was used for different types of free flap, including 24 superficial circumflex iliac artery perforator flaps, seven anterolateral thigh flaps, three peroneal artery perforator flaps, five medial femoral condyle osteo-adipofascial flaps, and three profunda artery perforator flaps.
- Correlation between the main clinical, imaging, and arthroscopy findings in patients with temporomandibular disordersby M. Fernández-Ferro, V. Fernández-González, Á. Salgado-Barreira, E. Santos-Armentia, P. Valdés-Sarmiento, A. Fernández-García, D. Gómez-Rey, J. Fernández-Sanromán on 17/08/2022 at 12:00 am
The purpose of this work was to prospectively correlate the most characteristic clinical symptoms of temporomandibular disorders, such as pain and limitation of mouth opening, with the findings of magnetic resonance imaging (disc position, degenerative changes, and effusion) and arthroscopy findings (roofing, synovitis, chondromalacia, adhesions, and perforations). These examinations were performed in 298 patients diagnosed with internal derangement refractory to conservative treatment. The mean age of the patients was 38.59 years; 92.6% were female.
- Tension pneumocephalus: case report and reviewby J.S. Jundt, A. Bohnen, B.S. Galbraith, J. Melville on 16/08/2022 at 12:00 am
Tension pneumocephalus is a rare complication of frontal sinus fracture or neurosurgical intervention resulting from compression of the brain by entrapped air, leading to seizure, altered mental status, brain herniation, and death. This report presents a case of traumatic tension pneumocephalus associated with an anterior and posterior table frontal sinus fracture in a patient with pneumosinus dilatans and osteogenesis imperfecta.
- Intraoperative evaluation of the resected bone margin in mandibular cancers using a trephine drill and frozen section analysisby P. Hegde, V. Gunishetty, V. Shetty, U. Shetty, S. Abraham, S. Bajjuri on 15/08/2022 at 12:00 am
The objective of this study was to evaluate the accuracy and feasibility of intraoperative frozen section analysis of samples harvested with a trephine drill from the bone resection margins to identify malignancy. Thirty-five patients who were diagnosed with locally advanced oral squamous cell carcinoma involving the mandible were included in this study. After tumour resection, bone samples were collected from the resection margin of the specimen using a trephine drill. Sampling yielded a cylindrical specimen of bony tissue that included both cortical and cancellous areas.
- Natural course of severe temporomandibular joint osteoarthrosis evaluated by a novel condylar remodelling scoring system and quantitative volumetric analysisby C.-K. Sun, Y.-B. Li, H.-S. Ma, G. Li, Z.-P. Sun, L.-S. Sun on 13/08/2022 at 12:00 am
Temporomandibular joint osteoarthrosis (TMJ-OA) frequently causes mild, moderate, or severe condylar morphological changes. A novel condylar remodelling scoring system (CRSS) based on three-dimensional cone beam computed tomography images is proposed, which is used to grade condylar morphological changes. In the CRSS, the condyle is divided into 10 regions by 11 reference points. For each increase in the number of regions involved in TMJ-OA, one point is subtracted from the full score of 10. The intra-class correlation coefficients for intra- and inter-observer agreement (range 0.656–0.898 and 0.841–0.906, respectively) indicated that the CRSS had good reliability.
- Stability of nasal symmetry following primary cleft lip and nasal repair: five years of follow-upby K. Alkebsi, K.A. Sakran, Y. Abdo, B. Shi, C. Li on 13/08/2022 at 12:00 am
Despite advances in cleft lip treatment, various levels of residual deformity remain after primary repair of cleft lip and palate. The aim of the current study was to compare the stability of short- and long-term postoperative nasal symmetry. This retrospective study included 100 consecutive non-syndromic patients with unilateral complete cleft lip who underwent primary cleft lip repair with follow-up of 5 years. Measurements taken from basal and frontal standard photograph views, obtained preoperatively (T1) and immediately (T2), 1 year (T3), and 5 years postoperative (T4), were analysed.
- Evaluation of bone gain in horizontal ridge augmentation using titanium mesh in combination with different flap advancement techniques: a randomized clinical trialby S. Bahaa, N. Diab, N. Zazou, M. Darhous, A.E. El Arab, H. ElNahass on 10/08/2022 at 12:00 am
The aim of this study was to investigate and compare the clinical and radiographic bone gain in guided bone regeneration with titanium mesh, for four different advancement techniques: periosteal releasing incision (PRI), double flap incision (DFI), modified periosteal releasing incision (MPRI), and coronally advanced lingual flap (CALF). Forty patients with a partially edentulous mandible were allocated randomly to four study groups (PRI, DFI, MPRI, CALF; 10 patients in each). Clinical bone gain (primary outcome) and radiographic bone gain were evaluated.
- Preoperative MRI for oral tongue squamous cell carcinoma: timing and correlation to histopathologyby N. Rozendorn, G. Greenberg, O. Madgar, I. Gluck, M. Vered, E. Alon, A. Dobriyan on 08/08/2022 at 12:00 am
Magnetic resonance imaging (MRI) is an integral part of the evaluation of local and regional disease in tongue squamous cell carcinoma prior to surgery. The aim of this study was to evaluate the accuracy of MRI in assessing tumour dimensions, as well as the impact of the time-lag from diagnostic biopsy on the accuracy of MRI. The medical records of 64 patients with tongue carcinoma were reviewed retrospectively. Tumour maximum diameter and tumour depth of invasion were compared between pathology and MRI (T1- and T2-weighted).
- Anterolateral thigh flap with a central hole for the repair of extensive oral defects in patients treated for chemotherapy-induced trismusby R. Li, Z. Meng, Y. Zhang, Y. He on 05/08/2022 at 12:00 am
Trismus is a rare complication of chemotherapy. The usefulness of a modified anterolateral thigh (ALT) flap for the repair of extensive oral defects in patients treated for chemotherapy-induced trismus was evaluated. Between 2019 and 2021, three patients with chemotherapy-induced trismus underwent scar excision. A thinned ALT flap with a central hole was designed to repair the resultant oral mucosal defects. The patients were followed up for a mean 9.3 months (range 4–18 months). The mean pre- and intraoperative maximum inter-incisal opening (MIO) was 0.7 cm (range 0–2.0 cm) and 3.6 cm (range 3.4–3.7 cm), respectively, indicating a significant operative effect.
- Does the presence of third molars during sagittal split mandibular ramus osteotomy favour complications? Systematic review and meta-analysisby B.B. de Souza, M.L.M. da Silveira, W.R.M. Dantas, R. A.C. Almeida, A.R. Germano on 04/08/2022 at 12:00 am
The aim of this systematic review and meta-analysis was to assess whether the presence of inferior third molars during sagittal split mandibular ramus osteotomy increases the risk of intraoperative and postoperative complications. The PRISMA protocol was followed in this study, and the review was registered in the PROSPERO database (CRD42020147642). A search was conducted in the MEDLINE (PubMed), Web of Science, Cochrane Central, and Scopus databases on November 1, 2021. Nineteen articles were included, and the variables analysed were unfavourable fractures, infection, neurosensory disturbance, removal of osteosynthesis material, and duration of surgery.
- Use of the high-dose pulsed hyaluronidase protocol in the management of impending skin necrosis associated with hyaluronic acid fillers: a systematic reviewby S. Al-Alam Sansur, D. Destang on 04/08/2022 at 12:00 am
Impending skin necrosis resulting from inadvertent intravascular injection of hyaluronic acid (HA) fillers can lead to tissue loss and significant scarring. In recent years, management trends have shifted from multimodal approaches to the sole use of high doses of hyaluronidase. The aim of this systematic review was to evaluate the effectiveness of the high-dose pulsed hyaluronidase management protocol in preventing skin necrosis and possible subsequent scarring. An online search of the bibliographic databases PubMed and Embase yielded 3039 articles.
- Three-dimensional dentoskeletal changes following minimally invasive surgically assisted rapid palatal expansion: a prospective studyby I. Camps-Perepérez, R. Guijarro-Martínez, B.M. da Rosa, O.L. Haas Jr., F. Hernández-Alfaro on 28/07/2022 at 12:00 am
Dentoskeletal changes in minimally invasive surgically assisted rapid palatal expansion (SARPE) were evaluated using cone beam computed tomography (CBCT). This was a prospective study of 30 patients who underwent minimally invasive SARPE performed under local anaesthesia plus sedation by the same surgeon, in an ambulatory setting. Pre- and postoperative CBCT images were obtained for each patient. A statistically significant increase in the linear transverse dimensions of the maxilla occurred systematically.
- The earliest known reported occurrence of dentigerous cyst in a six-month-old childby M. Patel, K. Schultz, E. Rosenfeld on 21/07/2022 at 12:00 am
The earliest reported case of the occurrence of a dentigerous cyst is described; the cyst surrounded an unerupted permanent tooth bud in a 6-month-old infant. Most commonly these lesions present between the second and third decades of life. They rarely occur before 10 years of age and have not been documented prior to 1 year of age. In the case reported here, the treatment instituted was extraction of the adjacent deciduous tooth and enucleation of the cyst along with the permanent molar tooth bud.
- Three-dimensional evaluation of postoperative stability: a comparative study between surgery-first and surgery-late protocolsby A. Valls-Ontañón, S. Triginer-Roig, I. Trujillo, P.J. Brabyn, M. Giralt-Hernando, F. Hernández-Alfaro on 21/07/2022 at 12:00 am
The main objective of this study was to compare the stability of the surgery-first and surgery-late approaches according to the standardized centre protocols, by three-dimensional evaluation after 1 year of follow-up. A retrospective study was designed that included a test group (surgery-first protocol) and a control group (surgery-late protocol), with a follow-up period of at least 1 year (average 14 months; range 12–24 months). Stability was evaluated using linear and angular measurements by superimposing cone beam computed tomography images obtained at specific points in time: preoperatively, 1 month after surgery, and at the end of the orthodontic treatment.
- Evaluation of facial soft tissue asymmetric changes in Class III patients after orthognathic surgery using three-dimensional stereophotogrammetryby E. Nike, O. Radzins, P. Pirttiniemi, V. Vuollo, A. Slaidina, A. Abeltins on 21/07/2022 at 12:00 am
The aim of this study was to investigate changes in facial soft tissue asymmetry over time after orthognathic surgery in Class III patients using three-dimensional stereophotogrammetry. The study included 101 patients with a skeletal Class III malocclusion (72 female, 29 male; age range 19–53 years, mean age 28.6 years) who underwent orthognathic surgery. The minimum follow-up was 12 months. Three-dimensional photographs were acquired using the 3dMDtrio stereophotogrammetry system, and 21 anthropometric landmark positions were evaluated at three time points: before surgery (T0), 6 months (T1) and 12 months (T2) after surgery.
- Clinical outcomes and cost-effectiveness of superficial parotidectomy versus extracapsular dissection of the parotid glandby D. Tretiakow, A. Skorek, T. Przewoźny on 19/07/2022 at 12:00 am
We read with interest the article by Vanroose et al. entitled “Clinical outcomes and cost-effectiveness of superficial parotidectomy versus extracapsular dissection of the parotid gland: a single-centre retrospective study of 161 patients”.1 The authors presented their observations and suggested that extracapsular dissection (ECD) of the parotid gland tumour showed excellent clinical outcomes and a reduction in complications compared to superficial parotidectomy in the case of superficial benign parotid gland tumours.
