- The use of cutting/positioning devices for custom-fitted temporomandibular joint alloplastic reconstruction: current knowledge and development of a new systemby S. Sembronio, A. Tel, M. Robiony on 20/10/2020 at 12:00 am
Alloplastic replacement of the temporomandibular joint (TMJ) is the treatment of choice in cases of TMJ end-stage disease. Improvements in computer-aided design/computer-aided manufacturing (CAD/CAM) translated into the possibility ongf designi very precise TMJ prostheses based on the anatomy of each single patient. Custom-made TMJ prostheses are described in the most recent literature and provide facilitations in terms of ease of placement and accuracy. Although before the era of custom-made surgical guides, they did not play a prominent role in the field of TMJ surgery, their use has become mandatory when custom-made prostheses are used.
- Intermittent intracranial condylar dislocation with minimal functional sequelaeby A. Zumbrunn Wojczyńska, B. Schuknecht, D.A. Ettlin on 17/10/2020 at 12:00 am
Degenerative changes of the temporomandibular joint (TMJ) present with a broad spectrum of morphological alterations. However, erosions leading to a glenoid fossa defect and condylar impingement of the temporal lobe are a rare finding. A 77-year-old female patient presented with limited mouth opening and pre-auricular pain during mastication on the left side. She denied any neurological dysfunction. Her medical history included poliomyelitis, multiple cancers, and osteonecrosis of the left tibial plateau.
- Three-dimensional stereophotogrammetry measurement of facial asymmetry in patients with congenital muscular torticollis: a non-invasive methodby H. Vallen, T. Xi, M. Nienhuijs, W. Borstlap, T. Loonen, B. Hoogendoorn, L. van Vlimmeren, T. Maal on 14/10/2020 at 12:00 am
The aim of this study was to evaluate three-dimensional (3D) stereophotogrammetry based methods for measuring craniofacial asymmetry in patients with congenital muscular torticollis (CMT). This study focused on the differences in craniofacial asymmetry in CMT patients compared with a healthy control group using 3D photographs. The difference in facial asymmetry between the CMT group and control group was measured using two methods to analyse facial asymmetry in distinct anatomical regions: (1) mirroring and surface-based registration to analyse the overall facial asymmetry; (2) the ‘coherent point drift’ based method.
- A 21-year analysis of the publication patterns and level of scientific evidence in three major oral and maxillofacial surgery journalsby D. Beteramia, A. Sklavos, A. Saha, D. Hyam on 14/10/2020 at 12:00 am
High-quality research in surgical sciences is constrained by a number of barriers including funding, blinding, adjusting for surgical experience, and inability to recruit sufficient numbers. As a result, surgeons have been reported to accept lower levels of scientific evidence to validate procedures. Our study analysed the quantity and quality of publications in three journals in Oral and Maxillofacial Surgery over a 21-year period. A retrospective analysis of all issues published between 1998 and 2018 in the International Journal of Oral and Maxillofacial Surgery, the British Journal of Oral and Maxillofacial Surgery and the Journal of Oral and Maxillofacial Surgery was conducted.
- Three-dimensional assessment of root migration and rotation patterns after coronectomy: bone-embedded roots versus soft tissue-covered rootsby Z.-Y. Yan, F. Wang, X.-Y. Yan, N. Ge, C.-B. Guo, K. Liu, N.-H. Cui on 14/10/2020 at 12:00 am
In this study, a three-dimensional evaluation was performed to explore differences between bone-embedded and soft tissue-covered roots after mandibular third molar (M3M) coronectomy. Patients were recruited according to the results of cone-beam computed tomography, 6 months after coronectomy. Completely bone-embedded M3Ms were assigned to group B, while completely soft tissue-covered M3Ms were assigned to group S. Data were recorded using digital software. A total of 213 M3Ms in 181 patients were investigated, of which 170 were assigned to the two study groups.
- The Sydney Modified Alberta Reconstruction Technique (SM-ART) for dental rehabilitation following mandibulectomy or maxillectomyby M. Johal, D. Leinkram, C. Wallace, J.R. Clark on 14/10/2020 at 12:00 am
The Sydney Modification of the Alberta Mandibular Reconstruction technique (SM-ART) is a hybrid of the Rohner method and the Alberta Reconstructive Technique (ART). SM-ART differs from ART in three ways, notably the use of custom plates, intraoral placement of implants via three-dimensionally printed guides and a skin graft buried deep into the skin paddle of the fibula flap in the first stage of the reconstruction.
- Bleomycin sclerotherapy in lymphangiomas of the head and neck region: a prospective studyby P. Tiwari, V. Pandey, R.N. Bera, S.P. Sharma, N. Chauhan on 12/10/2020 at 12:00 am
Intralesional sclerotherapy for lymphatic malformations (LMs) has become a modality of choice because of the high morbidity and recurrence rates with surgical excision. Traditionally, the macrocystic variant has shown good results with sclerotherapy. This prospective study was performed to evaluate the role of bleomycin sclerotherapy in the management of different radiological variants of LM. A total of 142 patients were included in this study. The lesions were classified as macrocystic, microcystic, or mixed LMs on the basis of ultrasonography.

The study by Huang et al. titled “Preliminary experience with promethazine hydrochloride injection in the sclerotherapy of oral mucocele” aimed to assess the short-term efficacy and safety of administering promethazine hydrochloride injections to treat oral mucoceles1. It is an interesting and unique study that gives us significant data regarding the efficacy of promethazine hydrochloride in the treatment of mucoceles of the minor salivary glands1.
- Skeletal, dental and facial aesthetic changes following anterior maxillary segmental distraction by tooth-borne device in patients with cleft lip and palateby Z. Zhang, P. Zhang, S. Li, J. Cheng, H. Yuan, H. Jiang on 11/10/2020 at 12:00 am
Maxillary skeletal deficiency secondary to cleft lip and palate (CLP) remains a significant challenge. The aim of this study was to present the comprehensive skeletal, dental and facial aesthetic outcomes of anterior maxillary segmental distraction osteogenesis (AMSDO) for treatment of maxillary hypoplasia in patients with CLP. Twelve patients with maxillary hypoplasia treated with AMSDO by a customized tooth-borne distractor were included. Three-dimensional changes of anterior maxillary segment, upper incisor and pharyngeal space were measured by three-dimensional reconstruction derived from cone beam computed tomography (CBCT) data.
- One-step lateral window approach for removal of benign minor sinus pathologies combined with transcrestal sinus floor elevation without bone grafts: a retrospective studyby W.-B. Park, K.L. Kang, J.S. Park, J.-Y. Han on 10/10/2020 at 12:00 am
The aim of this study was to evaluate the clinical and radiographic outcomes of a lateral window approach for removal of benign minor sinus pathologies combined with transcrestal sinus floor elevation. From 2014 to 2018, all patients who received sinus pathology removal via a lateral window approach combined with transcrestal sinus floor elevation were screened. The serous exudate or minor sinus pathology was drained or removed via lateral window approach. Subsequently, transcrestal sinus floor elevation without grafting and simultaneous implant placement were performed.
- Evaluation of long-term hard tissue relapse following surgical–orthodontic treatment in skeletal class II patients: A systematic review and meta-analysisby L. Gaitan-Romero, S. Shujaat, H. Ma, K. Orhan, E. Shaheen, D. Mulier, G. Willems, C. Politis, R. Jacobs on 08/10/2020 at 12:00 am
This systematic review and meta-analysis was performed to evaluate the long-term hard tissue stability and relapse factors following surgical–orthodontic treatment in skeletal class II patients. A literature search was conducted using Embase, Cochrane Central, Web of Science, and PubMed, yielding 3184 articles published up to January 2019. Risk of bias was assessed following the Cochrane handbook. Ten articles met the inclusion criteria. A total of 1079 patients were followed up for 5–13 years. The qualitative findings showed a variety of extrinsic and intrinsic factors affecting long-term stability.
- Temporomandibular joint reconstruction with medial femoral condyle osseocartilaginous flap: a case seriesby L. Xia, B. Jie, Y. Zhang, J. An, L. Zheng, Y. He on 08/10/2020 at 12:00 am
Reconstruction for large-scale temporomandibular joint (TMJ) defects can be challenging. We have used the medial femoral condyle (MFC) osseocartilaginous flap for repair of TMJ defects. The aim of this paper was to describe our technique and to present the preliminary results. The MFC osseocartilaginous flap was used as a free vascularized graft for TMJ defect in four patients who had undergone resection for benign tumor of the TMJ region (n = 2) or TMJ ankylosis (n=2). A computer-assisted technique was used in all cases.
- Preliminary experience with promethazine hydrochloride injection in the sclerotherapy of oral mucoceleby A. Chen on 08/10/2020 at 12:00 am
In this study, we took advantage of the corrosiveness of promethazine hydrochloride injection, i.e., its chemical corrosiveness at the injection site, for sclerotherapy of mucocele1. In previous reports, the more serious complications may have been caused by perivascular extravasation or unintentional intra-arterial injection, which is a common feature of all chemical corrosive sclerosants2. Therefore, in the sclerotherapy procedure, we emphasized that it is necessary to puncture into the lesion and aspirate saliva with viscous wire drawing to ensure correct positioning, and then inject the drug into the lesion1.
- Enhancement of bone perfusion through cortical perforations to improve healing of medication-related osteonecrosis of the jaw: a retrospective studyby Y. Guo, C. Guo on 03/10/2020 at 12:00 am
Medication-related osteonecrosis of the jaw (MRONJ) is generally difficult to treat. So far, no optimal strategy for MRONJ has been established. The aim of this study was to determine whether a new surgical technique, i.e. curettage with cortical perforations of healthy adjacent bone that enhances bone perfusion would be more effective than standard curettage in treating patients with MRONJ. Twenty-eight MRONJ patients who underwent curettage treatment with or without cortical perforation technique at our institution between June 2014 and May 2016 were included in this retrospective study.
- Evaluation of DNA methylation in matched oral swab and tissue specimens from Chinese patients with oral squamous cell carcinomaby R. Sun, W.-B. Zhang, Y. Yu, H.-Y. Yang, G.-Y. Yu, X. Peng on 03/10/2020 at 12:00 am
The DNA methylation statuses of the paired box 1 (PAX1) and zinc finger protein 582 (ZNF582) genes have shown promise in the detection of oral squamous cell carcinoma (OSCC). The aim of this study was to investigate the ability of PAX1 and ZNF582 methylation to distinguish OSCC and the adjacent normal tissue among cancer patients. This study included 67 patients with OSCC. The methylation levels of these two genes were analysed in tissue specimens (lesion site and adjacent normal site) and in oral swabs (lesion site and contralateral normal site).
- Proceedings from the OMS Resurgence Conference for resuming clinical practice after COVID-19 in the USAby T.T. Wang, H.S. Moon, A. Le, L.R. Carrasco, N. Panchal on 30/09/2020 at 12:00 am
The COVID-19 pandemic has altered and reshaped the delivery of oral and maxillofacial surgery (OMS) over the past few months. As the USA gradually lifts restrictions and re-opens, surgeons must adjust accordingly. Therefore, the OMS Resurgence Conference: Safely Resuming Practice with a New Normal was organized for 11 May 2020 to gather and disseminate expert opinions and recommendations for OMSs to thoughtfully resume work with efficiency and safety. This manuscript offers a summary of the highlights from the conference discussion.
- Blunt cerebrovascular injuries in the craniofacial fracture population—Are we screening the right patients?by T. Puolakkainen, L. Vähäsilta, F. Bensch, M. Narjus-Sterba, M.L. Wilson, H. Thorén, J. Snäll on 26/09/2020 at 12:00 am
Current knowledge of blunt cerebrovascular injuries (BCVIs) in craniomaxillofacial fracture (CMF) patients is limited. The purpose of this study was to determine the occurrence of BCVIs in patients with all types of CMF. This retrospective study included CMF patients in a level 1 trauma centre during a 3-year period. Patients who were not imaged with computed tomography angiography and patients with mechanisms other than blunt injury were excluded. The primary outcome variable was BCVI. A total of 753 patients were included in the analysis.
- Second metatarsal free transfer in total temporomandibular joint reconstruction for ankylosis in a child: 10-year follow-upby M. Olivetto, J. Bettoni, S. Testelin, S. Dakpé, B. Devauchelle on 26/09/2020 at 12:00 am
The management of temporomandibular joint (TMJ) ankylosis requires complete removal of the ankylosed block and the prevention of recurrence. For this purpose, the ramus–condyle unit can be reconstructed with a second metatarsal free flap. This article reports the use of this flap in a young patient treated for left TMJ ankylosis, post costochondral graft for the treatment of hemifacial microsomia. Data from the 10-year follow-up are reported. The glenoid fossa was reconstructed with a graft of the second metatarsal base, enabling the juxtaposition of two cartilaginous joint surfaces, with the aim of optimizing the functional result and preventing the recurrence of ankylosis.
- Trust, but verify: response to “Titanium plate removal in orthognathic surgery: prevalence, causes and risk factors. A systematic literature review and meta-analysis”by B. Gareb, N.B. van Bakelen, P.U. Dijkstra, A. Vissink, R.R.M. Bos, B. van Minnen on 26/09/2020 at 12:00 am
We read with great interest the work of Gómez-Barrachina et al.1. Their systematic review covers the prevalence, causes, and risk factors of titanium plate removal in orthognathic surgery. We have some concerns, however, regarding the completeness of the review due to the search strategy used and the interpretation of funnel plots.

- Validity of computed tomography in diagnosing midfacial fracturesby M.F. de Carvalho, J.N.M. Vieira, R. Figueiredo, P. Reher, B.R. Chrcanovic, M. das Graças Afonso Miranda Chaves on 23/09/2020 at 12:00 am
The aim of this study was to evaluate the sensitivity, accuracy, and reliability of two-dimensional computed tomography (2D-CT) scans (axial, coronal, sagittal planes) and three-dimensional computed tomography (3D-CT) reconstructions in diagnosing midfacial fractures in relation to actual fractures identified clinically and during surgery (gold standard). The imaging diagnosis was performed by a radiologist and an oral and maxillofacial surgeon. Sixty-two patients with a total of 429 midfacial fractures were included.
- Where is the ‘wisdom’ in wisdom tooth surgery? A review of national and international third molar surgery guidelinesby Y. Gadiwalla, R. Moore, N. Palmer, T. Renton on 20/09/2020 at 12:00 am
The objective of this narrative review was to identify and evaluate published international guidelines on mandibular third molars (M3M) and to assess their clinical scope and the validity of the recommendations. The search strategy used data obtained from a variety of sources including MEDLINE, national regulatory bodies, national dental and surgical colleges and associations, and military medical departments. Adherence to clinical guideline development was investigated using the AGREE II instrument (Appraisal of Guidelines for Research and Evaluation).
- Immediate dental implant placement with a horizontal gap more than two millimetres: a randomized clinical trialby B.M. Naji, S.S. Abdelsameaa, A.Y. Alqutaibi, W.M. Said Ahmed on 17/09/2020 at 12:00 am
The purpose of this study was to evaluate the horizontal dimensional changes in buccal alveolar bone immediately after dental implant placement in the upper premolar area with horizontal gaps >2mm. A total of 48 patients were enrolled in this randomized clinical trial and were randomly assigned to one of three groups. Group I (flap with graft; n=16) patients received an immediate implant with bone graft, membrane, and primary flap closure. Group II (flap without graft; n=16) patients received an immediate implant with primary flap closure only.
- Effect of platelet-rich fibrin on the control of alveolar osteitis, pain, trismus, soft tissue healing, and swelling following mandibular third molar surgery: an updated systematic review and meta-analysisby J. Zhu, S. Zhang, X. Yuan, T. He, H. Liu, J. Wang, B. Xu on 16/09/2020 at 12:00 am
The purpose of this study was to estimate the effect of platelet-rich fibrin (PRF) on the control of alveolar osteitis (AO), pain, trismus, soft tissue healing, and swelling following mandibular third molar surgery. A comprehensive search of the literature was conducted through PubMed, Embase, Web of Science, and Cochrane Library up to May 2019. Randomized controlled studies conforming to the inclusion criteria were included. The record screening and data extraction were conducted by two authors independently.
- Safety concerns for facial topography customized 3D-printed N95 filtering face-piece respirator produced for the COVID-19 pandemic: initial step is respiratory fit testingby A.R. Scott, J. Hu, C. Gan, J.A. Morris, K.W. Meacham, D.H. Ballard on 14/09/2020 at 12:00 am
We commend the authors of the article “Custom-made 3D-printed face masks in case of pandemic crisis situations with a lack of commercially available FFP2/3 masks”1 for their determination in providing rapid solutions to personal protective equipment (PPE) shortages during times of crisis. However, we feel that it is misleading to provide a face mask solution without discussion of proper fit testing (quantitative or qualitative), which importantly may put individuals trying to replicate it at increased risk.
- Reply to Scott et al., “Safety concerns for facial topography customized 3D-printed N95 filtering face-piece respirator produced for the COVID-19 pandemic: initial step is respiratory fit testing”by P.E. Haers, G.R.J. Swennen on 14/09/2020 at 12:00 am
The safety concerns raised in the letter of Scott et al. are correct and have obviously to be addressed.
- Accuracy of fit analysis of the patient-specific Groningen temporomandibular joint prosthesisby B.J. Merema, J. Kraeima, M.J.H. Witjes, N.B. van Bakelen, F.K.L. Spijkervet on 14/09/2020 at 12:00 am
Total joint replacement (TJR) with a prosthesis can be indicated for patients with severe temporomandibular joint (TMJ) dysfunction. Surgical accuracy is necessary for correct translation of the preoperatively predicted functional outcome, wear, and biomechanical behaviour of the patient-specific TMJ-TJR prosthesis. This study describes the first clinical applications of the patient-specific TMJ-TJR prosthesis according to the Groningen principles (G-TMJ-TJR), which was developed and validated in a prior human cadaver test study.

The aim of this study was to highlight several misleading imaging and clinical aspects of parotid gland lymphoma, taking our personal experience and relevant literature reports into consideration. The records of all patients diagnosed with lymphoma in the parotid gland between 2005 and 2017 were examined retrospectively. Sixty-seven patients were included in this study. The mean age was 61.4 years. The most frequent histological entities were marginal zone B-cell lymphoma (31.3%) and follicular lymphoma (28.4%).
- Diagnostic performance of mobile cone beam computed tomography versus conventional multi-detector computed tomography in orbital floor fractures: a study on human specimensby A.S. Lacagne, E. Brumpt, A. Barrabé, E. Pomero, B. Chatelain, F. Grillet, E. Weber, A. Malakhia, M. Pons, S. Aubry, C. Meyer, N. Sigaux, A. Louvrier on 10/09/2020 at 12:00 am
The aim of this study was to evaluate the diagnostic accuracy of mobile cone beam computed tomography (MCBCT) versus multi-detector computed tomography (MDCT) in orbital floor fractures. Twenty-four fresh cadaver heads were used, and one orbital floor was fractured for each head by transconjunctival approach. MDCT and MCBCT were performed on each of the heads. The images obtained were then analysed independently by eight evaluators. The radiological characteristics of the orbital floor fractures were visualized with good interpretation agreement between the two images.
- Comparison between computer-guided and freehand dental implant placement surgery: A systematic review and meta-analysisby F.C. Yogui, F.R. Verri, J.M. de Luna Gomes, C.A.A. Lemos, R.S. Cruz, E.P. Pellizzer on 10/09/2020 at 12:00 am
The purpose of this systematic review was to compare computer-guided (fully guided) and freehand implant placement surgery in terms of marginal bone loss, complications, and implant survival. This review followed the PRISMA guidelines and was registered in the PROSPERO database (CRD42019135893). Two independent investigators performed the search of the PubMed/MEDLINE, Scopus, and Cochrane Library databases for studies published up to April 2020 and identified 1508 references. After a detailed review, only four studies were considered eligible.
- Do positional changes of the inferior alveolar canal after sagittal split mandibular osteotomy affect neurosensory recovery?by O. Doganay, A. Houle, M.D. Han, M. Miloro on 10/09/2020 at 12:00 am
The purpose of this study was to assess the pre- and postoperative position and dimensions of the inferior alveolar canal (IAC) following sagittal split osteotomy (SSO) and identify any association with postoperative neurosensory deficit (NSD) at 1 year. This retrospective cohort study enrolled consecutive patients who had SSO performed to correct skeletal malocclusion. The pre- and postoperative cone beam computed tomography data were superimposed to visualize differences in IAC position and dimensions.
- Accuracy of maxillary repositioning surgery using CAD/CAM customized surgical guides and fixation platesby A. Wong, M.S. Goonewardene, B.P. Allan, A.S. Mian, A. Rea on 09/09/2020 at 12:00 am
The advent of three-dimensional imaging and computer-aided surgical simulation (CASS) have brought about a paradigm shift in surgical planning. The aim of this study was to assess the accuracy of maxillary repositioning surgery using computer-aided design and manufacturing (CAD/CAM) customized titanium surgical guides and fixation plates. Thirty consecutive adult patients, 13 male and 17 female, with a mean age of 29.2 years and 25.5 years, respectively, requiring Le Fort I maxillary osteotomy, with or without simultaneous mandibular surgery, were evaluated retrospectively.
- The healthcare burden and associated adverse events from total alloplastic temporomandibular joint replacement: a national United States perspectiveby Kevin C. Lee, Nikita Chintalapudi, Steven Halepas, Sung-Kiang Chuang, Firat Selvi on 08/09/2020 at 12:00 am
The purpose of this study was to provide a United States perspective on alloplastic total joint replacement. We sought to estimate the inpatient burden and report the most common adverse events using two administrative datasets. The National Inpatient Sample was queried from October 2015 to December 2016 for total joint replacement admissions using International Classification of Diseases 10th revision codes, and the Manufacturer and User Facility Device Experience registry was queried from January 2009 to September 2019 using manufacturer brands.
- The impact of delayed diagnosis on the outcomes of oral cancer patients: a retrospective cohort studyby A. Thomas, S. Manchella, K. Koo, A. Tiong, A. Nastri, D. Wiesenfeld on 08/09/2020 at 12:00 am
The contemporary literature is discordant regarding the role of delayed diagnosis in the prognosis of patients with oral cancer. This study examined data on a previously reported cohort of 101 patients with oral squamous cell carcinoma diagnosed at a single institution between 2008 and 2010. The time interval between symptom onset and initial histological diagnosis (diagnostic delay) was recorded for each patient, as were demographic data and cancer features such as T stage, nodal status, and smoking status.

A systematic review of the frontal sinus fracture management literature was undertaken to document measurable outcomes, with emphasis on complications associated with the various treatment strategies. A comprehensive electronic search was undertaken in October 2018. Randomized controlled trials (RCT), controlled clinical trials, retrospective and prospective studies describing the management of frontal sinus fractures and complications were included. Twenty-four publications were included: one reporting a prospective RCT and 23 reporting consecutive case series studies (four prospective, 19 retrospective).
- Is low or high body mass index in patients operated for oral squamous cell carcinoma associated with the perioperative complication rate?by W. Do, T. Elzerman, R. de Bree, A. Rosenberg, T. Forouzanfar, E.M. Van Cann on 27/08/2020 at 12:00 am
The aim of this study was to analyse the effect of body mass index (BMI), both low and high values, on the perioperative complication rate in patients with oral squamous cell carcinoma (OSCC). The medical records of 259 patients operated between 2014 and 2017 for OSCC were reviewed. Univariate and multivariate analyses were performed. Sixty of the 259 patients developed 87 complications. Low or high BMI was not associated with the perioperative complication rate. A longer operating time and increased blood loss were associated with a higher perioperative complication rate and higher Clavien–Dindo grade.
- Evaluation of airflow characteristics before and after septoplasty in unilateral cleft patients with a deviated nasal septum: a computational fluid dynamics studyby M. Ramanathan, P. Ramesh, N. Aggarwal, A. Parameswaran, H.F. Sailer, A.E. George on 27/08/2020 at 12:00 am
The aim of this study was to evaluate changes in airflow characteristics before and after septoplasty in unilateral cleft lip and palate (UCLP) patients using computational fluid dynamics (CFD) models. The study was designed as a prospective cohort study involving pre- and postoperative computed tomography data from 12 UCLP patients with a deviated nasal septum who underwent septoplasty. CFD analysis of nasal airflow was conducted to study changes in velocity, pressure, volume, nasal resistance, and wall shear stress of the nasal domain before and after surgery.
- Challenges of tracheostomy in COVID-19 patients in a tertiary centre in inner city Londonby E. Yeung, P. Hopkins, G. Auzinger, K. Fan on 27/08/2020 at 12:00 am
The rapid global spread of SARS-CoV-2, the causative agent of COVID-19, has dominated healthcare services, with exponential numbers requiring mechanical ventilation in the intensive care unit (ICU). Tracheostomy facilitates respiratory and sedative weaning but risks potential viral transmission. This study reviewed the tracheostomy provision, techniques, and outcomes for a single-centre prospective cohort during the resource-pressured COVID-19 period. Seventy-two of 176 patients underwent tracheostomy at a median 17 days: 44 surgical (open), 28 percutaneous.
- Role of structures in the masticator space in selecting patients with resectable T4b oral cancer: findings from a survival analysisby Ajay Kumar, Rahul Singh, Manu Santhosh, Sandeep Vijay, Nigil Surendran, Guru Charan Sahu, Naveen George, Raveena Nair, Sithara A, Aswathi K, Adharsh Anand, Sajith Babu Thavarool on 26/08/2020 at 12:00 am
Oral squamous cell cancers involving the masticatory space are staged as unresectable cancers and their treatment is difficult. Curative treatment with extensive surgery followed by adjuvant therapy is one of the treatment options. In this retrospective study, the survival of 123 patients (93 with T4a cancers, 30 with T4b cancers), treated during the period August 2009 to August 2015, was evaluated. The majority had bucco-alveolar cancers (62.6%), were male (61.8%), and were tobacco users (76.4%).
- Arthroscopic diagnosis and medical management of calcium pyrophosphate deposition disease in the temporomandibular jointby D.D. Choi, D. Smith, C.M. Davis, J.P. McCain on 26/08/2020 at 12:00 am
Calcium pyrophosphate deposition disease (CPPD) is a crystal arthropathy that can involve the temporomandibular joint. It is known to accelerate the osteoarthritic process, often initially presenting with advanced level of disease. The management of CPPD in the rheumatology and orthopedic literature is one of early diagnosis and medical management of acute attacks. The cases of three patients who presented with initial complaints of joint pain and limited mouth opening are presented. Preoperative imaging identified calcifications in two of these patients.
- Neck involvement and disease recurrence in adenoid cystic carcinoma of the minor salivary glands: the role of surgery in primary and progressive diseaseby J. Moratin, A. Ledermann, A.D. Schulz, K. Metzger, O. Ristow, C. Hofele, M. Engel, J. Hoffmann, K. Freier, K. Lang, S. Adeberg, D. Horn, C. Freudlsperger on 23/08/2020 at 12:00 am
The aim of this study was to analyse the rates of metastatic events and clinical outcomes of patients with adenoid cystic carcinoma (ACC) of the minor salivary glands and to critically evaluate the role of surgical therapy. A retrospective cohort study was designed including all patients with ACC of the oral minor salivary glands treated in the study department during the years 2010–2017. Relevant clinicopathological data were analysed to determine factors with an impact on overall survival (OS) and progression-free survival (PFS).
- Medication-related osteonecrosis of the mandible: an unusual presentation and treatmentby R. Rothweiler, P.J. Voss, R. Schmelzeisen, M.C. Metzger on 23/08/2020 at 12:00 am
A 71-year-old woman was referred to the clinic with extensive medication-related osteonecrosis of the jaw (MRONJ) involving the mandible. She had received 7 years of zoledronate therapy. On cone beam computed tomography, the MRONJ presented as a large sequestrum spanning from the left to the right condylar process, surrounded by thick sub-periosteal bone. The sequestrum was excised via an intraoral approach, leaving the newly formed sub-periosteal bone as a neo-mandible. The patient recovered well from the operation and was discharged 5 days after surgery.
- Feasibility of virtual surgical simulation in the head and neck region for soft tissue reconstruction using free flap: a comparison of preoperative and postoperative volume measurementby S. Yokoi, N. Nishio, Y. Fujimoto, M. Fujii, K. Iwami, Y. Hayashi, K. Takanari, M. Hiramatsu, T. Maruo, N. Mukoyama, H. Tsuzuki, A. Wada, Y. Kamei, M. Sone on 19/08/2020 at 12:00 am
In the head and neck region, preoperative evaluation of the free flap volume is challenging. The current study validated preoperative three-dimensional (3D) virtual surgical simulation for soft tissue reconstruction by assessing flap volume and evaluated fat and muscle volume changes at follow-up in 13 head and neck cancer patients undergoing anterolateral craniofacial resection. Patients received 3D virtual surgical simulation, and the volume of the planned defects was estimated by surgical simulation.
- Short-term condylar and glenoid fossa changes in infants with Pierre Robin sequence undergoing mandibular distraction osteogenesisby S.M. Susarla, E. Mercan, K. Evans, M.A. Egbert, R.A. Hopper on 17/08/2020 at 12:00 am
The purpose was to evaluate short-term changes in condylar and glenoid fossa morphology in infants with Pierre Robin sequence (PRS) undergoing early (age <4 months) mandibular distraction osteogenesis (MDO) for the management of severe airway obstruction. Computed tomography data from infants with PRS who had MDO were compared to those of age-matched control infants without facial skeletal dysmorphology. Surface/volume, linear, and angular measurements of the condyle and glenoid fossa were obtained and compared between infants with PRS and controls.
- Reply to Letter to the Editor “Comfort and compliance with the use of facemasks during COVID-19 infection”by P.E. Haers, G.R.J. Swennen on 17/08/2020 at 12:00 am
We thank the author for their letter. The author correctly states that it is essential to use the mask in real-life situations before its widespread production. This is indeed correct, and no mask should be used until proven safe and not to cause complications, in particular dermatological issues.
- Comparison of postoperative complications and facial nerve recovery rates after conventional and partial superficial parotidectomy of benign parotid tumours: a prospective studyby M.A. Al-Aroomi, M.A. Mashrah, B.M. Abotaleb, J. Sun, N.A. Al-Worafi, Y. Huang, F. Xie on 17/08/2020 at 12:00 am
The aim of this study was to compare postoperative complications and facial nerve (FN) recovery rates between conventional superficial parotidectomy (CSP) and partial superficial parotidectomy (PSP) as surgical treatment for benign parotid tumours. A prospective study was conducted on 55 consecutive patients who underwent either CSP (n=35) or PSP (n=20) for benign parotid tumours. The primary outcomes were FN injury, FN recovery rates, and Frey syndrome. Secondary outcomes were operative time, hospital stay, sialocele, haematoma, and auricular numbness.
