by A. Prevost, C. Dekeister, P. Caron, P. Imbert, Z. Cavallier, F. Lauwers, F. Boutault on 28/02/2020 at 12:00 am
Thyroid-associated ophthalmopathy can result in proptosis. In such cases, orbital decompression surgery is often warranted to reduce the adverse impact on patient quality of life. Due to the anatomical complexity of the orbit, navigation can be of considerable assistance during orbital decompression. The objective of this study was to evaluate the benefits of using a surgical navigation device in orbital decompression surgery. A retrospective study was performed based on patients who underwent decompression surgery with (N+) or without (N−) a navigation device between 1997 and 2017.
The effect of omega-3 in temporomandibular joint synovial tissues of rats with induced arthritis: pilot study
by T. Barbin, F.C. Groppo, F.C. Toledo, Y.M. Costa, J.T. Clemente-Napimoga, S.R. Figueroba on 28/02/2020 at 12:00 am
This study evaluated the effect of systemic administration of omega-3 on the expression of interleukins IL-1β and IL-10 and tumour necrosis factor alpha (TNF-α) and on the thickness of cartilage in the temporomandibular joint (TMJ) inflammatory model induced by complete Freund’s adjuvant (CFA). Thirty-two adult rats were divided equally into four groups: control, CFA (induced arthritis), and induced arthritis animals treated with dexamethasone or omega-3. The TMJs were then removed and assigned to histomorphometric analysis or immunoassay.

by B.R. Keyser, A.K. Banda, L.G. Mercuri, G. Warburton, S.M. Sullivan on 26/02/2020 at 12:00 am
The aim of this study was to survey an international group of temporomandibular joint surgeons regarding their outcomes with alloplastic total joint replacement in skeletally immature patients and to review the literature linked to autogenous reconstruction and alloplastic replacement of the temporomandibular joint (TMJR) in this population. A total of 24 custom/patient-specific TMJ Concepts devices were implanted into 14 patients (eight male and six female). Their mean age was 14 years (range 7–17 years).
Dental implant placement in alveolar cleft patients: a retrospective comparative study on clinical and aesthetic outcomes
by J.M. Alberga, K. Stellingsma, H.J.A. Meijer, H.A. Oostenbrink, A. Vissink, G.M. Raghoebar on 22/02/2020 at 12:00 am
The aim of this retrospective study was to assess the clinical and aesthetic outcomes, and patient satisfaction, following dental implant therapy in cleft patients. Implant survival, changes in marginal bone level, pocket probing depths, plaque and bleeding indices, aesthetics, and patient satisfaction were assessed in 17 alveolar cleft patients and 17 matched controls. At follow-up (mean 72.4±46.4 months), one implant had been lost in the cleft group. Mean marginal bone loss at follow-up was −0.4±0.4mm in cleft patients and −0.2±0.4mm in controls.
Imaging characteristics of the mandible and upper airway in children with Robin sequence and relationship to the treatment strategy
by Z. Mao, N. Zhang, L. Shu, Y. Cui on 20/02/2020 at 12:00 am
Some patients with Robin sequence (RS) may respond to conservative therapy, while others require surgery; however, there are currently no objective anatomical criteria to gauge surgical indication. The purpose of this study was to explore the imaging characteristics of the mandible and upper respiratory tract in children with RS and examine how individual morphometric parameters influence the treatment strategy. Cone beam computed tomography (CBCT) images were obtained from 57 children with RS. Twenty parameters were measured as potential surgical indicators.
In response to the Letter to the Editor entitled “Confounding factors in the efficacy of intraosseous and submucosal dexamethasone injection in mandibular third molar surgery”
by W. Powcharoen on 20/02/2020 at 12:00 am
We are grateful for the author’s interest in our recent trial entitled “Comparison of intraosseous and submucosal dexamethasone injection in mandibular third molar surgery: a split-mouth randomized clinical trial”1. We also appreciate the valuable comments that will support important findings of this trial. As mentioned in the Letter to the Editor, the author raised three interesting points.
Confounding factors in the efficacy of intraosseous and submucosal dexamethasone injection in mandibular third molar surgery
by D. Patel on 20/02/2020 at 12:00 am
I read with great interest the article by Kaewkumnert et al.1 in a recent issue of the International Journal of Oral and Maxillofacial Surgery. The authors performed a randomized trial of 27 patients undergoing third molar extractions who received an intraosseous injection of dexamethasone 4mg to one side of the mandible and a submucosal injection to the other side. They concluded that both techniques of dexamethasone injection were effective in controlling pain and swelling after mandibular third molar surgery, but that the submucosal injection was superior for the control of trismus.
Cross-septal returned flap: modified endoscopic technique for bilateral closure of septal perforation
by Y. Rusetsky, Z. Mokoyan, O. Spiranskaya, S. Arutyunyan on 20/02/2020 at 12:00 am
Endoscopic approaches for septal perforation closure have achieved a certain popularity. Many of the flaps described provide unilateral closure of the perforation. Thus, complete restoration of the normal multilayer septal anatomy is still challenging, particularly in children. This article presents a modified technique for endoscopic bilateral surgical repair of nasal septal perforations. A novel cross-septal returned flap was performed in nine patients with nasal septal perforations. The mean size of the perforation was 17.7mm in the sagittal axis and 16.9mm in the vertical axis.

by J.-K. Ku, P.-Y. Yun, Y.-K. Kim, J.H. Kim on 18/02/2020 at 12:00 am
A dacryolith is a rare finding and can be considered as a complication of a Le Fort I fracture. A case of dacryolith and nasolacrimal duct obstruction after surgery for a Le Fort I fracture is described, and the reasons for and prevention of this condition are discussed.
Does the Brown classification of maxillectomy defects have prognostic prediction for patients with oral cavity squamous cell carcinoma involving the maxilla?
by Q. Sun, W.-B. Zhang, M. Gao, S. Yu, C. Mao, C.-B. Guo, G.-Y. Yu, X. Peng on 18/02/2020 at 12:00 am
The aim of this study was to investigate the correlation between the maxillectomy defect, T stage, and prognosis of patients with maxillary squamous cell carcinoma (SCC). The Brown classification system was used to appraise the maxillectomy defects due to maxillary SCC. The clinical data of 137 patients with maxillary SCC during the period 2000–2010 were reviewed; 105 patients were followed up. Preoperative T stage and postoperative maxillectomy class were recorded. The relationship between the maxillectomy defect class and T stage of maxillary SCC was analysed.
Three-dimensional facial volume analysis using algorithm-based personalized aesthetic templates
by A. Jorien Tuin, Jene W. Meulstee, Tom G.J. Loonen, Joep Kraeima, Fred K.L. Spijkervet, Arjan Vissink, Johan Jansma, Rutger H. Schepers on 18/02/2020 at 12:00 am
Three-dimensional stereophotogrammetry is commonly used to assess volumetric changes after facial procedures. A lack of clear landmarks in aesthetic regions complicates the reproduction of selected areas in sequential images. A three-dimensional volumetric analysis was developed based on a personalized aesthetic template. The accuracy and reproducibility of this method were assessed. Six female volunteers were photographed using the 3dMDtrio system according to a clinical protocol, twice at baseline (T1) and twice after 1year (T2).

by X. Liu, S. Wan, A. Abdelrehem, M. Chen, C. Yang on 07/02/2020 at 12:00 am
This article introduces a modified surgical approach combining condylotomy with posterior disc attachment release for the resection of large non-malignant masses located in the infratemporal fossa and involving the skull base. This retrospective study included 14 patients treated at Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University between January 2010 and December 2016. Clinical evaluations (visual analogue scale (VAS) for pain, maximum inter-incisal opening (MIO), and complications) and radiological findings (magnetic resonance imaging (MRI) and computed tomography (CT)) were collected pre- and postoperatively.
CYFRA 21-1 and MMP-9 as salivary biomarkers for the detection of oral squamous cell carcinoma: a systematic review of diagnostic test accuracy
by A.M. AlAli, T. Walsh, M. Maranzano on 05/02/2020 at 12:00 am
Tissue biopsy with histopathological examination is still considered the gold standard to diagnose oral squamous cell carcinoma (OSCC). This systematic review explored the diagnostic test accuracy of two salivary biomarkers in adults suspected of OSCC. The Cochrane Library, MEDLINE, and Embase databases were searched for clinical studies evaluating the diagnostic accuracy of salivary biomarkers in detecting OSCC. Studies were eligible for inclusion if only singular salivary biomarkers were evaluated in three or more studies.
Comparison of hand-sewn versus modified coupled arterial anastomoses in head and neck reconstruction: a single operator’s experience
by Z. Guo, W. Cui, M. Hu, B. Yu, B. Han, Y. Li, X. Tang, C. Li, L. Li on 05/02/2020 at 12:00 am
Microvascular coupler devices have gained wide acceptance as an alternative to the traditional hand-sewn technique in reconstructive surgery. However, no study has directly compared the efficacy of the coupler and hand-sewn techniques in arterial anastomosis during head and neck reconstruction surgery. A total of 123 patients who underwent surgery performed by a single surgeon between 2016 and 2018 were included in this retrospective study. The patients were divided into the coupler group and the hand-sewn group according to the technique of arterial anastomosis used.
The effect of alcohol on facial Trauma outcomes: an analysis of the National Trauma Data Bank
by E. Paw, J.K. Canner, E.R. Haut, M. Manukyan on 31/01/2020 at 12:00 am
Maxillofacial trauma costs emergency departments approximately one billion dollars annually. Facial trauma has increased since 2000 and has been attributed to both increased use of computed tomography and interpersonal violence. Alcohol, male sex, and age 18–35 years are significant risk factors for interpersonal violence. This study is novel in using a large database to look at the effect of alcohol on clinical outcomes in facial trauma. A data analysis was performed in Stata/MP 14.2 using variables coded from the National Trauma Data Bank (NTDB); logistic regression was applied.

by D.-D. Wang, H.-Y. Luo, C.-B. Guo, J.-H. Meng on 31/01/2020 at 12:00 am
The objective of this study was to summarize diagnostic points and treatment strategies for diffuse tenosynovial giant cell tumours (D-TSGCTs) of the temporomandibular joint (TMJ), and to evaluate the expression of proteins related to bone destruction and recurrence. The clinical and histopathological characteristics of 24 cases were analysed retrospectively. TRAP staining and immunohistochemical staining for MMP-9, MMP-13, and Ki-67 were performed. The median age of the patients was 45.5 years; the female to male ratio was 1.7:1.
Regional differences in temporomandibular joint inflammation in patients with juvenile idiopathic arthritis: a dynamic post-contrast magnetic resonance imaging study
by K. Buch, Z.S. Peacock, C.M. Resnick, H. Rothermel, L.B. Kaban, P. Caruso on 31/01/2020 at 12:00 am
The purpose was to determine whether there are regional differences in temporomandibular joint (TMJ) inflammation in patients with juvenile idiopathic arthritis (JIA). This was a retrospective study of all patients with dynamic, contrast-enhanced magnetic resonance imaging through the TMJs at Massachusetts General Hospital between January 2015 and July 2016. The patient cohort included those with a history of JIA and control patients who underwent MRI for other routine clinical purposes. TMJ inflammation was quantified as the difference between post-gadolinium and pre-gadolinium articular T1 signal intensity normalized to post-gadolinium signal intensity of the longus capitis muscle.
Long-term comparison study of philtral ridge morphology with two different techniques of philtral reconstruction
by F.C.-S. Chang, C.G. Wallace, Y.-C. Hsiao, J.-J. Huang, C.S.-W. Liu, Z.-C. Chen, P.K.-T. Chen, J.-P. Chen, Y.-R. Chen on 30/01/2020 at 12:00 am
Cleft lip and/or cleft palate are the most common congenital craniofacial anomalies. Philtral ridge morphology is an important aesthetic component of unilateral cleft lip (UCL) repair. To this end, we have developed two techniques of philtral ridge reconstruction: (1) asymmetric mattress muscle sutures, and (2) overlapping mattress muscle sutures. The objective of this retrospective cohort study was to compare their outcomes in UCL repairs. Group I patients (n=30) underwent UCL repair before August 2003, including philtral ridge reconstruction by asymmetric mattress muscle sutures.
A pedicled palatal periosteal flap for the closure of oro-antral fistula
by K. Blal, M. Alterman, J. Abu Tair on 28/01/2020 at 12:00 am
Various surgical techniques have been developed for oro-antral fistula (OAF) closure, all of which have some drawback. Twenty consecutive patients with an OAF were enrolled in this prospective study. A trapezoid full-thickness flap extending from the palatal area to the buccal gingiva was raised, including the fistula at its centre. The palatal free end aspect was split into two layers and the deep periosteal layer was folded deep to the flap over the bony defect, thereby sealing the fistula. The superficial layer was returned to its primary position and sutured.
Endoscopic sinus surgery for dental implant displacement into the maxillary sinus—a retrospective clinical study
by A. Safadi, O.J. Ungar, I. Oz, I. Koren, A. Abergel, S. Kleinman on 28/01/2020 at 12:00 am
The aims of this retrospective clinical study were to present our management protocol for the retrieval of impacted dental implants that have become displaced into the maxillary sinus cavity and to define the role of endoscopic sinus surgery in this setting. All 24 patients (25 implants) who underwent surgical retrieval of dental implants displaced into the maxillary sinus between 2012 and 2019 were included. Data on surgical interventions and complications were collected retrospectively. Eleven patients (46%) had chronic sinusitis associated with the migrated implant.

by F.L. Shoukair, A. Maly, T.K. Haran, N. Hirshoren, J. Abu Tair on 28/01/2020 at 12:00 am
Considering the confusion in the literature regarding local recurrence, spread, or metastases of pleomorphic adenoma (PA) in the head and neck region, the aim of this study was to enhance understanding of the characteristics of metastasizing pleomorphic adenoma (MPA) by reviewing the literature and presenting a case. English language articles with proof of metastases were included in the literature review. Of the 80 cases in the literature with MPA, 46 were female and 33 were male (sex missing for one case).
Oral health-related quality of life in tumour patients treated with patient-specific dental implants
by P. Jehn, S. Spalthoff, P. Korn, M. Stoetzer, M. Gercken, N.-C. Gellrich, B. Rahlf on 25/01/2020 at 12:00 am
Dental rehabilitation after surgically acquired bone deficiency related to tumour treatment remains a challenge. The insertion of patient-specific implants geared to the contour of the remaining bone is a feasible method of supporting fixed or removable dentures. As oral health-related quality of life (OHRQoL) is of great interest in these cases, 12 individuals treated with patient-specific implants for severe bone deficiency were surveyed and their Oral Health Impact Profile (OHIP) scores after dental rehabilitation were evaluated.
The use of xenografts to prevent inferior border defects following bilateral sagittal split osteotomies: three-dimensional skeletal analysis using cone beam computed tomography
by H.C. van der Helm, J. Kraeima, T. Xi, J. Jansma, R.H. Schepers on 24/01/2020 at 12:00 am
The aim of this retrospective study was to investigate grafting in the osteotomy gap during bilateral sagittal split osteotomy (BSSO), using a xenograft and fibrin glue. Hard tissue defects in the inferior mandibular border were assessed using cone beam computed tomography scans taken 1 week and 1year postoperatively. The study group of 20 patients underwent bone grafting during BSSO (mean age 26.1years; mean horizontal displacement 8.5mm) and the control group of 20 patients did not (mean age 30.2 years; mean horizontal displacement 7.6mm).
Oral Epstein–Barr virus-positive mucocutaneous ulcer: gingival presentation of a benign lymphoproliferative lesion
by D.T.S. Li, A.W.I. Lo, Y.-X. Su on 22/01/2020 at 12:00 am
Epstein–Barr virus-positive mucocutaneous ulcer (EBVMCU) is a benign lymphoproliferative lesion related to iatrogenic or age-related immunosuppression in patients with prior Epstein–Barr virus (EBV) infection. Although the clinical presentation may resemble malignant disease, the course of EBVMCU is indolent, and regression is expected when immunosuppression is reduced. We present a case of EBVMCU in the gingiva of a 59-year-old male patient with long-standing pemphigus vulgaris. The initial presentation was suspicious for oral cavity cancer, which was ruled out by biopsy.
Fraser syndrome: review of the literature illustrated by a historical adult case
by J. Bouaoud, M. Olivetto, S. Testelin, S. Dakpe, J. Bettoni, B. Devauchelle on 22/01/2020 at 12:00 am
Fraser syndrome (cryptophthalmos–syndactyly syndrome) is a rare autosomal recessive malformation disorder. The first description of the syndrome was reported by George Fraser in 1962. Diagnosis is based on the major and minor criteria established by van Haelst et al. in 2007. Unilateral or bilateral cryptophthalmos, syndactyly, unilateral renal agenesis, and genital anomalies are the most frequent anomalies. Several maxillofacial, oro-dental, ear–nose–throat, hormonal, and anorectal disorders are reported.
Effectiveness of occlusal splint therapy in the management of temporomandibular disorders: network meta-analysis of randomized controlled trials
by E.A. Al-Moraissi, R. Farea, K.A. Qasem, M.S. Al-Wadeai, M.E. Al-Sabahi, G.M. Al-Iryani on 22/01/2020 at 12:00 am
A network meta-analysis (NMA) of randomized controlled trials (RCTs) was performed to assess the effectiveness of various types of occlusal splint in the management of temporomandibular disorders (TMDs) and to rank them according to their effectiveness. An electronic search was undertaken to identify RCTs published until August 2019. Predictor variables were control, non-occluding splint, hard stabilization splint (HSS), soft stabilization splint (SSS), prefabricated splint, mini-anterior splint, anterior repositioning splint (ARS), and counselling therapy (CT) with or without HSS.
Comparison of islanded facial artery myomucosal flap with fasciocutaneous free flaps in the reconstruction of lateral oral tongue defects
by S.T. Joseph, Naveen B.S., M.T. Mohan, J. Tharayil on 21/01/2020 at 12:00 am
The aim of this study was to determine whether the islanded facial artery myomucosal flap (iFAMM) is a good alternative to fasciocutaneous free flaps (FCFF) in the reconstruction of lateral oral tongue defects. This was a retrospective study of 40 patients with oral tongue cancers (lateral lesions not >4 cm) operated on between August 2014 and March 2017, who underwent primary reconstruction with either an iFAMM or FCFF. The two groups were compared with respect to intraoperative time, total intensive care unit (ICU) and hospital stay, complications, speech, swallowing, aesthetics, donor site morbidity, and economic feasibility.

by B.C. Lopes da Silva, G.F. Machado, E.F. Primo Miranda, E.L. Galvão, S.G.M. Falci on 20/01/2020 at 12:00 am
The aim of this systematic review was to compare the triangular and envelope flaps in mandibular third molar surgery with regard to pain, oedema, and trismus. Secondary outcomes assessed were dehiscence, ecchymosis, alveolar osteitis, periodontal condition, and surgical time. The PRISMA guidelines and recommendations in the Cochrane Handbook were followed, and the review was registered before commencement (PROSPERO; CRD42018112373). The literature search was conducted in the Web of Science, PubMed, Virtual Health Library, Cochrane Library, and Scopus databases and in the grey literature; randomized clinical trials, indexed through November 2018 were included.
Chimeric posterior tibial artery flap: clinical application in oral and maxillofacial reconstruction
by M.A. Mashrah, L. Mai, Q. Wan, C. Pan on 13/01/2020 at 12:00 am
The objective was to describe the utility of the chimeric posterior tibial artery flap (CPTAF) in the restoration of compound defects in the oral and maxillofacial region. Patients who underwent head and neck reconstruction using a CPTAF between February 2018 and February 2019 were included. Special consideration was given to the distribution of septocutaneous perforators (SPs), indications, flap survival, and complications. Nine patients were included. All flaps survived. One patient developed a surgical site infection, which was managed conservatively.

by S. Yanamoto, Y. Denda, Y. Ota, T. Hasegawa, M. Akashi, M. Okura, S.-I. Yamada, H. Kurita, N. Yamakawa, T. Kirita, M. Ueda, M. Umeda, the Japan Oral Oncology Group (JOOG) on 13/01/2020 at 12:00 am
Extranodal extension (ENE) of lymph node metastasis and the presence of a positive or close margin (PCM) are major risk factors for head and neck squamous cell carcinoma recurrence. This retrospective multicentre cohort study compared the prognostic impact of postoperative radiotherapy (RT) and concurrent chemoradiotherapy (CCRT) in oral squamous cell carcinoma (OSCC) patients at high risk of recurrence. One hundred and eighteen patients with PCM and/or ENE who underwent definitive surgery plus either adjuvant RT or CCRT using cisplatin for OSCC were investigated.
In vivo investigation of temporomandibular joint regeneration: development of a mouse model
by M.A. Hakim, F.P.S. Guastaldi, A. Liapaki, D.Y. Ahn, M.-L. Mueller, M.J. Troulis, J.P. McCain on 13/01/2020 at 12:00 am
Temporomandibular joint (TMJ) reconstruction is traditionally invasive. Several investigators have developed animal models, including mouse models, to study the TMJ. However, there are no detailed descriptions of a mouse model to be followed for additional research. The goal of this project was to study minimally invasive TMJ regeneration using tissue engineering in mice. As part of the project, a detailed mouse model was developed, which is described in this article. Eight carcasses were used to study the anatomy of the TMJ of the mouse and 36 mice were used to describe the surgical approach and perioperative management.
Relevance of 3D virtual planning in predicting bony interferences between distal and proximal fragments after sagittal split osteotomy
by A. Valls-Ontañón, R.D.J. Ascencio-Padilla, A. Vela-Lasagabaster, A. Sada-Malumbres, O.L. Haas-Junior, J. Masià-Gridilla, F. Hernández-Alfaro on 13/01/2020 at 12:00 am
After sagittal split osteotomy, the mandibular distal and proximal fragments do not always align themselves passively to one another, resulting in bony interferences and subsequent anomalous settlement of the condyles. Predicting these interferences could be an important ancillary procedure for avoiding intra- and postoperative surgical complications, rendering orthognathic surgery more effective and safer. This study evaluated the relevance of virtual surgical planning in assessing the displacement of the proximal segments after virtual distal segment repositioning, for predicting bony interferences between the segments and thus avoiding related intra- and postoperative surgical complications.
“One-piece” patient-specific reconstruction plate for double-barrel fibula-based mandibular reconstruction
by W.F. Yang, W.S. Choi, W.Y. Zhu, Y.X. Su on 28/12/2019 at 12:00 am
Segmental mandibular defects require reconstruction. The fibula flap serves as a versatile flap in restoring mandibular contour and bony height. With the advances in computer-aided design and additive manufacturing technology, an innovative “one-piece” patient-specific reconstruction plate to facilitate double-barrel fibula flap shaping and bone securing was developed; the plate is described in this study. The “one-piece” plate is fabricated with individualized specifications and is mainly composed of three components: the long-bar reconstruction plate, a short-bar plate, and connecting bars.
Adenoid cystic carcinoma of the palate with isolated cutaneous metastasis: a unique case and review of current and future treatment modalities of metastatic disease
by L.T.D. Armstrong, S.S. Subramaniam, S. Borgna on 28/12/2019 at 12:00 am
Adenoid cystic carcinoma (ACC) is an aggressive salivary gland neoplasm characterized by high rates of local recurrence, early metastasis, and a poor long-term prognosis. Approximately 20–50% of cases result in distant metastasis, commonly involving the lung, bone, liver, and brain. Cutaneous metastasis is a rare occurrence, with a small number of cases reported previously in the context of multiple metastatic sites of involvement. We present a unique case of ACC of the hard palate with isolated cutaneous metastasis.
Clinical efficacy of acellular dermal matrix for plastic periodontal and implant surgery: a systematic review
by W. Lu, G. Qi, Z. Ding, X. Li, W. Qi, F. He on 27/12/2019 at 12:00 am
This review was performed to validate the clinical efficacy of acellular dermal matrix (ADM) for plastic periodontal and implant surgery. Four electronic databases and a manual search were utilized to select randomized clinical trials (RCTs) published until March 2019. Overall, 28 RCTs were included: 25 on teeth and three on implants. For plastic periodontal surgery, ADM exhibited a comparable gingival recession reduction (RecRed) and soft tissue thickness (STT) gain to connective tissue graft (CTG).
Accuracy of mandible-independent maxillary repositioning using pre-bent locking plates: a pilot study
by H. Imai, K. Fujita, Y. Yamashita, Y. Yajima, H. Takasu, A. Takeda, K. Honda, T. Iwai, K. Mitsudo, T. Ono, S. Omura on 27/12/2019 at 12:00 am
The double splint method is considered the gold standard for maxillary repositioning, but the procedure is lengthy and prone to error. Recent splintless methods have shown high repositioning accuracy; however, high costs and technical demands make them inaccessible to many patients. Therefore, a new cost-effective method of mandible-independent maxillary repositioning using pre-bent locking plates is proposed. Plates are bent on maxillary models in the planned position prior to surgery. The locations of the plate holes are replicated during surgery using osteotomy guides made from thermoplastic resin sheets.
Is alteration of the occlusal plane stable with isolated nasomaxillary fixation of the Le Fort I osteotomy?
by S.M. Susarla, R.E. Ettinger, K. Preston, H. Kapadia, M.A. Egbert on 26/12/2019 at 12:00 am
The purpose of this work was to evaluate the stability of maxillary position in the setting of occlusal plane rotations in bimaxillary surgery with rigid fixation of the mandible and bilateral nasomaxillary fixation at the Le Fort I level. This was a retrospective assessment of patients undergoing bimaxillary surgery for the correction of dentofacial deformities with occlusal plane alterations. Demographic measures assessed included age, sex, history of craniofacial anomaly, segmental maxillary osteotomy, and maxillary bone grafting.

by Matthew Yekikian, Laurent Ganry, Rui Fernandes on 21/12/2019 at 12:00 am
The purpose of this study was to identify complication rates of thyroidectomies performed within the Department of Oral and Maxillofacial Surgery, University of Florida Health – Jacksonville, and to compare these with quantified data regarding complications of thyroidectomies performed by other specialties. A retrospective cohort analysis was implemented to determine complication rates amongst patients treated in the department between January 2012 and December 2017. Data variables included demographics, ASA status, social history, and preoperative signs and symptoms.
Upper airway stimulation as an alternative to maxillomandibular advancement for obstructive sleep apnoea in a patient with dentofacial deformity: case report with literature review
by S.O. Hong, S. Poomkonsarn, G. Millesi, S.Y.C. Liu on 21/12/2019 at 12:00 am
Obstructive sleep apnoea (OSA) is characterized by repeated upper airway collapse leading to oxygen desaturation resulting in cardiovascular and neurocognitive sequelae. Upper airway surgeries such as palatopharyngoplasty, tongue base surgery, and maxillomandibular advancement can improve patient tolerance of continuous positive airway pressure, quality of life, and the severity of OSA. Upper airway stimulation (UAS) of the hypoglossal nerve is a contemporary US Food and Drug Administration-approved treatment modality for OSA with a fundamentally different mechanism.
Single-stage bone resection and cranioplastic reconstruction: comparison of a novel software-derived PEEK workflow with the standard reconstructive method
by Philippe Dodier, Fabian Winter, Thomas Auzinger, Gabriel Mistelbauer, Josa M. Frischer, Wei-Te Wang, Ammar Mallouhi, Wolfgang Marik, Stefan Wolfsberger, Lukas Reissig, Firas Hammadi, Christian Matula, Arnulf Baumann, Gerhard Bavinzski on 20/12/2019 at 12:00 am
The combined resection of skull-infiltrating tumours and immediate cranioplastic reconstruction predominantly relies on freehand-moulded solutions. Techniques that enable this procedure to be performed easily in routine clinical practice would be useful. A cadaveric study was developed in which a new software tool was used to perform single-stage reconstructions with prefabricated implants after the resection of skull-infiltrating pathologies. A novel 3D visualization and interaction framework was developed to create 10 virtual craniotomies in five cadaveric specimens.
Virtual planning, simultaneous dental implantation and CAD/CAM plate fixation: a paradigm change in maxillofacial reconstruction
by T. Seier, L. Hingsammer, P. Schumann, T. Gander, M. Rücker, M. Lanzer on 20/12/2019 at 12:00 am
Prosthetic rehabilitation in patients undergoing reconstructive surgery using vascularized free flaps is challenging, and functional rehabilitation of the patient with a fixed prosthesis is rare. Virtually planned maxillofacial reconstruction including simultaneous dental implantation according to the prosthodontic ideal position of the implants could further enhance dental rehabilitation. The data of 21 patients undergoing fibula free flap reconstructive surgery with CAD/CAM patient-specific reconstruction plates during the years 2015–2018 were analysed, including the applicability of the virtual plan, flap survival, duration of surgery, ischemia time, simultaneous dental implantation, implant exposure, and postoperative complications.
Prognostic significance of lymphovascular invasion in patients with salivary duct cell carcinoma of the head and neck
by Y.M. Park, M.A. AlHashim, S.O. Yoon, Y.W. Koh, S.-H. Kim, J.Y. Lim, E.C. Choi on 19/12/2019 at 12:00 am
The purpose of this study was to evaluate the treatment outcomes of patients who underwent surgery with curative intention after the diagnosis of salivary duct cell carcinoma (SDC) in the head and neck area and to analyse the prognostic factors and treatment failure pattern. Fifty-nine patients treated between March 2003 and December 2018 were enrolled in the study. The mean follow-up period was 45.5 months (range 12–189 months). The 5-year overall survival rate was 54.7% and the 5-year disease-free survival rate was 56.8%.
Inflammatory pseudotumour of the alveolar process of the maxilla as clinical manifestation of IgG4-related disease: a case report and literature review
by W.L. Kouwenberg, F.J. Dieleman, S.M. Willems, A.J.W.P. Rosenberg on 18/12/2019 at 12:00 am
IgG4-related disease (IgG4-RD) is an uncommon immune-mediated condition considered to be a systemic disease, described in multiple organ systems. IgG4-RD that involves the maxillary and sinonasal region is rare. This report presents a very rare presentation of IgG4-RD in the maxillary alveolar process. The patient presented with left-sided facial pain, headache, and mobility and loss of teeth. The first biopsy and resection specimen reports were inconclusive and showed a non-specific chronic inflammatory process.
Assessment of the contralateral facial artery pedicle nasolabial island flap for buccal defect repair
by X. Zhou, S.-E. Zhang, P. Nueangkhota, Y.-J. Liang, Y.-X. Su, G.-Q. Liao on 15/12/2019 at 12:00 am
The facial artery pedicle nasolabial island flap (FAPNIF) is widely used for oral and maxillofacial reconstruction. However, its use in reconstruction after malignant tumour resection is limited by the possibility of ipsilateral cervical lymph node metastasis along the facial artery. Through fine dissection, it was found that the contralateral FAPNIF can be used to repair the defect after buccal carcinoma resection. The aim of this study was to evaluate the clinical outcomes of the contralateral FAPNIF for buccal defect repair.
Real-time optical vascular imaging: a method to assess the microvascular circulation of myofascial free flaps used in the head and neck region
by P. Bastos, A. Fry, L. Cascarini, E. Yeung, R. Cook on 13/12/2019 at 12:00 am
Microvascular free flaps are considered the gold standard in head and neck reconstructive surgery. Myofascial flaps, in particular, are useful in certain oral and maxillofacial reconstruction cases, where mucosal regeneration over the transplanted tissue is planned. Despite high success rates, 1–6% of free flaps fail. A plethora of methods are available to assess transplanted tissue viability after reconstruction, including clinical observational monitoring, surface Doppler, implantable Doppler probe, colour Doppler sonography, laser Doppler flowmeter, surface temperature and indocyanine green angiography.
Biodegradable versus titanium osteosynthesis in maxillofacial traumatology: a systematic review with meta-analysis and trial sequential analysis
by B. Gareb, N.B. van Bakelen, P.U. Dijkstra, A. Vissink, R.R.M. Bos, B. van Minnen on 06/12/2019 at 12:00 am
Titanium osteosynthesis is currently the fixation system of choice in maxillofacial traumatology. Biodegradable osteosynthesis systems have the ability to degrade in the human body. The aim of this study was to conduct a systematic review, with meta- and trial sequential analyses, to assess the efficacy and morbidity of biodegradable versus titanium osteosynthesis after maxillofacial trauma. MEDLINE, Embase, and CENTRAL were searched for randomized controlled trials and prospective and retrospective controlled studies.
