- Investigating the correlation between bone density and fracture frequency in the mandibular condyle with micro-computed tomographyby A.J. Thirunavukarasu, A. Ferro, S. Singh Dubb, D.L. Hamilton, C. Brassett on 22/01/2021 at 12:00 am
Fractures of the mandibular condyle are common and include diacapitular fractures that affect the condylar head. The medial part of the condylar head is least commonly fractured, possibly due to decreased propensity for lines of force to run in the region. Micro-computed tomography (X-ray microtomography) of five temporomandibular joint specimens was conducted to explore whether trabecular bone structure correlates positively with fracture prevalence, which could reflect adaptation in response to lower exposure to physiological loads throughout life.
- Orthognathic surgery in Covid-19 times, is it safe?by P. Glen, F. Aurora, S. Thomas, D. Kissun on 21/01/2021 at 12:00 am
Covid-19 has impacted the provision of orthognathic surgery globally. Uncertainty around its effects and transmission in aerosol generating procedures (AGP’s) has led to disagreement within maxillofacial surgeons into the safety of orthognathic surgery during the pandemic.We present a local case series of orthognathic surgery undertaken during the Covid-19 pandemic. To our knowledge no such similar study has been reported worldwide.
- More evidences are needed in reducing the suicide risk in head and neck cancer patientsby Lin Du, Hong-Lin Chen on 21/01/2021 at 12:00 am
We read with interest a structured review by Twigg et al.1 evaluating the prevalence of suicide in head and neck cancer (HNC) survivor and appropriate interventions in reducing the suicide risk in head and neck cancer patients, and commend the authors on this review. Here, we offer some discussion points regarding this structured review.
- Donor site local anaesthetic infusion catheter as an opioid sparing agent in free flap reconstruction of the head and neck: a valuable adjunct to an enhanced recovery protocolby Cían J. Henry, Conor P. Barry on 21/01/2021 at 12:00 am
This paper presents the results of a retrospective case-controlled cohort study to investigate the effectiveness of a donor site local anaesthetic infusion protocol in reducing opioid requirements, length of Intensive Therapy Unit (ITU) stay and the incidence of post-operative delirium. Adult free flap head and neck patients were identified from a prospective database. Eighty-six patients were included. There was a significant reduction in mean opioid requirement (p < 0.001). Post-operative delirium was observed in 12 out of 35 patients before introduction of the protocol, and 10 out of 51 patients after introduction (p = 0.139).
- Response to: “More evidences are needed in reducing the suicide risk in head and neck cancer patients”by J.A. Twigg, J.M. Anderson, G. Humphris, I. Nixon, S.N. Rogers, A. Kanatas on 21/01/2021 at 12:00 am
We thank the authors for their interest in our review paper “Best practice in reducing the suicide risk in head and neck cancer patients: a structured review”1 and for their constructive and insightful comments. While there are multiple observational studies evaluating suicide risk among HNC patients, there is a conspicuous dearth of evidence relating to suicidal ideation or demonstrating the utility of specific interventions to reduce the frequency or intensity of suicidal thoughts, or indeed reduce risk of suicide attempts or completion in this high-risk population.
- Evaluation of the course of the marginal mandibular branch of the facial nerve: a fresh cadaveric studyby A. Sindel, Ö. Özalp, N. Yıldırımyan, N. Oğuz, M. Sindel, V. llankovan on 19/01/2021 at 12:00 am
The aim of this study was to determine the course of marginal mandibular nerve (MMN) in relation to the inferior border of the mandible from the gonion until its terminal insertion to the depressor anguli oris, relating the position to a palpable anatomical landmark with emphasis on the depth of the nerve in relation to platysma and the deep cervical fascia. Twelve fresh adult cadavers were dissected and the mandibular base was contoured using needles with 5mm gaps, starting from the mandibular angle to the muscular termination point of the nerve bilaterally.
- Evaluation and comparison of anti-inflammatory properties of ibuprofen using two drug delivery systems after third molar surgery: using chitosan microspheres as a carrier for local drug delivery in to the third molar socket and through the oral routeby Karthik KP, Balamurugan R on 19/01/2021 at 12:00 am
We undertook this study to assess the analgesic and anti-inflammatory properties of ibuprofen when administered through two drug delivery systems after mandibular third molar surgery. The study was conducted on 100 patients who required the surgical removal of impacted mandibular third molars under local anaesthesia. The study subjects were divided into two groups of 50 patients each. Patients in the study group were given ibuprofen-incorporated chitosan-based microspheres, which were packed into the third molar sockets after removal of impacted teeth.

- Minimize damage of heat generated during drilling procedureby Yang Yao, Jianyu Chen on 17/01/2021 at 12:00 am
It’s significant for clinicians to reduce the impact of heat produced during drilling procedure. The conclusion that drilling with higher speed produces less heat and maintains more viability than lower speed interests us greatly. After reading the article by Hamdy A. M. Marzooka et al (In-vitro assessment of bone viability with different implant drill speeds.)1, we have several questions to ask.
- BAOMS QOMS (Quality and Outcomes in Oral and Maxillofacial Surgery): a specialty-wide quality improvement initiative, progress since conceptionby M.W. Ho, F. Puglia, D. Tighe, G.A. Chiu, F. Ridout, I. Hutchison, M. Mason, J.M. McMahon on 17/01/2021 at 12:00 am
The long-term sustainability of providing oral and maxillofacial care in the NHS relies on the specialty’s ability to demonstrate the cost-effectiveness of its treatment and the clear health benefits in line with best evidence-based practice, both in terms of objective outcomes and meeting patient expectations. However, the specialty lags behind other surgical specialties in terms of publication of clinical outcomes across the UK e.g. Vascular Services Quality Improvement Programme, Perioperative Quality Improvement Project (PQIP)1 and Trauma Audit and Research Network (TARN)2.
- What is a better modality of maxillomandibular fixation, Bone supported Arch Bars or Erich Arch Bars? A Systematic Review and Meta-analysisby Anuj Jain, Saumya Taneja, Anshul Rai on 17/01/2021 at 12:00 am
Any procedure aimed at management of maxillofacial fracture is incomplete without a meticulous maxillomandibular fixation (MMF). Since decades, Erich Arch Bars (EABs) are being used for this purpose. But with advent of Bone supported Arch Bars (BSABs), more surgeons are preferring them over conventional EABs. The present study is designed to identify which among the aforementioned two MMF modalities is a better one.
- Stability of fixation methods in large mandibular advancements after sagittal split ramus osteotomy: an in vitro biomechanical studyby K. Kuik, J.-P.T.F. Ho, M.H.T. de Ruiter, C. Klop, C.J. Kleverlaan, J. de Lange, A. Hoekema on 16/01/2021 at 12:00 am
Sagittal split ramus osteotomy (SSRO) with large mandibular advancements is a common surgical procedure and could be indicated for patients with sleep apnoea. As a large variety of fixation methods is used for the stabilisation of SSRO, a biomechanical test model was used to analyse which fixation technique was most stable. For this in vitro study, 80 polyurethane hemimandibles with a prefabricated SSRO were used as substrates. Loads in Newtons were recorded at displacements of the mandibular incisive edge at 1mm, 3mm and 5mm.

- Safer Surgical Practice: A Guide for Surgeons (not just for pandemics)by A.G.C. Hay-David, J.B.T. Herron, P.A. Brennan on 15/01/2021 at 12:00 am
The surgical working environment has changed considerably since the World Health Organisation (WHO) declared the coronavirus outbreak, COVID-19 (SARS-CoV-2), a pandemic on 11 March 2020. Measures remain in place to reduce the risk of spread from patients to surgeons, nosocomial infection and amongst healthcare workers. However, despite these protective measures, healthcare staff are at risk with the number of health workforce deaths increasing worldwide.This article sets out to explore the roles and responsibilities of the surgeon during these extraordinary times and discuss how we can improve our practice to reduce the risk of harm to patients, surgical staff and ourselves.

- Patients’ narratives of orthognathic treatment for facial asymmetry: a qualitative studyby J.E. Kettle, Z. Marshman, L. Winchester, L. Hardwick, R. Bolt, N. Lee on 12/01/2021 at 12:00 am
To explore patients’ experiences of orthognathic treatment for facial asymmetry and their adaptation to facial changes after surgery, we did a qualitative, cross-sectional study of patients after treatment for non-cleft asymmetry at two UK sites. A total of 15 patients aged 19-40 years were approached after being identified using patient databases and clinical notes. Individual and photo-elicitation interviews were conducted covering experiences prior to treatment, during treatment, and after surgery.
- Pleomorphic dermal sarcoma: a clinical and histological review of 49 casesby C.M. Bowe, B. Godhania, M. Whittaker, S. Walsh on 10/01/2021 at 12:00 am
Pleomorphic dermal sarcoma (PDS) is a rare mesenchymal neoplasm that shares histopathological features with atypical fibroxanthoma (AFX), but has additional features of deep invasion of the superficial subcutis, tumour necrosis, and vascular and perineural invasion, which confers a risk of local recurrence and metastases. To study the clinical and pathological spectrum more comprehensively, we retrieved 49 cases of pleomorphic dermal sarcoma from our departmental files. There was a strong male predominance (n=45).
- Extranodal extension in head and neck squamous cell cancer: is there a role for further stratification?by G. Tirelli, M. Tofanelli, E. Sacchet, R. Bussani, V. Shafiei, A. Gatto, P. Boscolo-Rizzo, N. Gardenal on 10/01/2021 at 12:00 am
To investigate the prognostic significance of the stratification of extranodal extension (ENE) into ENE minor (ENEmi, up to 2mm) and ENE major (ENEma, over 2mm) in non-HPV-related squamous cell cancers of the head and neck, we retrospectively reviewed microscopic slides from neck dissection specimens of ENE-positive patients and subcategorised them into ENEmi and ENEma. We then compared the two groups in terms of overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS).
- Stability and surgical complications of tooth-borne and bone-borne appliances in surgical assisted rapid maxillary expansion: a systematic reviewby M.E. Muñoz-Pereira, O.L. Haas-Junior, L. Da Silva Meirelles, A. Machado-Fernández, R. Guijarro-Martínez, F. Hernández-Alfaro, R.B. de Oliveira, R.M. Pagnoncelli on 08/01/2021 at 12:00 am
The objective of this systematic review was to evaluate the stability and complications of tooth-borne (TB), bone-borne (BB) and hybrid (TB-BB) appliances in surgically assisted rapid maxillary expansion (SARME). Database searches were conducted (PubMed, Embase, Cochrane Library and SciELO), as well as a grey literature search (Google Scholar) and hand searches of reference lists. Forty-six articles were included after study selection (κ=0.854). After eligibility assessment, 16 articles and one article from the grey literature were processed (κ=0.866) and six articles were selected by hand searching, for a total of 23 articles included.
- Role of Carnoy’s solution as treatment adjunct in jaw lesions other than odontogenic keratocyst: A systematic reviewby Babu Lal, Rudra Deo Kumar, Ragavi Alagarsamy, Shanmuga Sundaram D, Ongkila Bhutia, Ajoy Roychoudhury on 08/01/2021 at 12:00 am
Carnoy’s solution (CS) is routinely used as adjuvant therapy in the management of odontogenic keratocyst (OKC) and a few other benign lesions. The purpose of this study was to explore the evidence of application and efficacy in benign lesions other than OKC. We have systematically reviewed published articles to identify the evidence of CS in benign jaw lesions other than OKC following the PRISMA guidelines. The search was conducted in PubMed, Google Scholar, Semantic Scholar, and Cochrane Library database, to find relevant articles from 1980 to March 2020.
- Prevalence of lower limb venous disease in surgeons: a case study and results of a survey by the BAOMS Reconstruction Surgical Subspecialty Interest Group (SSIG)by Derek Falls, Michael Nugent, Ajay Wilson, Michael Ho on 08/01/2021 at 12:00 am
We report a case of venous leg ulceration in a Reconstructive Oral and Maxillofacial Surgeon. An online survey was created by the BAOMS Reconstruction SSIG primarily targeting head and neck surgeons to investigate the perceived risk and occurrence of venous leg disease. Two respondents had received treatment for lower limb venous disease thus compromising their ability to work, while 13 had symptoms of early venous disease. Our study shows an interesting area of concern for occupational health in surgeons, particularly those carrying out long operations as will be the case for Reconstruction SSIG members.

We have repeated the study during the second lockdown, and present our findings highlighting the main differences and learning issues as the services have evolved during the pandemic.
- Use of knotless barbed sutures for closure of intraoral incisions for maxillofacial trauma: a randomised controlled trialby A.K. Sharma, G.P. Thulasi Doss, E. Panneerselvam, S.K. Ganesh, V.B. Krishna Kumar Raja on 28/12/2020 at 12:00 am
The objective of this study was to assess the efficacy of knotless barbed sutures in intraoral wound closure for maxillofacial trauma in comparison with conventional (vicryl) sutures. This was a randomised controlled clinical trial involving 40 patients with isolated mandibular angle fractures who required intraoral incisions for open reduction and internal fixation (ORIF). The sample was randomised into the study group (20 patients) and control group (20 patients). Following fracture fixation by a standardised surgical protocol, the wound closure was done with bidirectional knotless barbed suture and vicryl for the study and control groups, respectively.
- Remifentanil-related muscle rigidity during osteotomy proceduresby Ben J Steel, Katrina A Denholm, Upma Misra, David JW Keith, Robert J Banks on 28/12/2020 at 12:00 am
We write to draw attention to muscle rigidity as an important adverse effect of remifentanil use in anaesthesia. Remifentanil is a short-acting synthetic opioid often used in combination with propofol as a form of TIVA (total intra-venous anaesthesia) or with inhalational agents. These drug combinations provide good equilibrium between depth of anaesthesia and recovery time and obtund noxious stimuli. Use of remifentanil in orthognathic surgery has been advocated to produce conditions of hypotensive anaesthesia, associated with reduced blood loss and haemodynamic stability intra-operatively.
- Effect of glucosamine sulphate on the temporomandibular joint of ovariectomised ratsby S.R. Figueroba, J.C. Moreira, K.S. Amorim, L.D.L.L. Cunha, T.M.L. Morais, L.E.N. Ferreira, F.C. Groppo on 28/12/2020 at 12:00 am
Glycosamine is an amino-monosaccharide present in connective and cartilage tissues that contribute to the maintenance, resistance, flexibility, and elasticity of these tissues. This study aimed to determine the in vivo effects of glucosamine sulphate (GS) on the temporomandibular joint (TMJ) of ovariectomised rats (OVX).Thirty-two rats were distributed into four groups as follows: G1, sham-OVX+saline solution; G2, sham-OVX+glucosamine sulphate (80mg/kg) – oral administration; G3, OVX+saline solution; G4, OVX+glucosamine sulphate (80mg/kg) – oral administration.
- Some weighting of publication rates should be used to more fairly reflect the productivity of trainees. Re: Variation in UK Deanery publication rates in the British Journal of Oral and Maxillofacial Surgery: where are the current ‘hot spots’?by A. Begley, P. Magennis on 25/12/2020 at 12:00 am
We commend Turner et al1 for their hard work but would point out that to compare BJOMS publication rates without considering the number of trainees in each rotation risks misrepresenting their productivity.
- Evaluation of segmental mandibular resection without a microvascular reconstruction in patients affected by medication-related osteonecrosis of the jaw: a systematic reviewby Roberto Sacco, Gezala Umar, Raphael Capelli Guerra, Oladapo Akintola on 24/12/2020 at 12:00 am
Medication-related osteonecrosis of the jaw (MRONJ) is a severe condition, which affects the jaw in patients exposed to specific drugs. More often, it has been described in association with patients receiving primarily bisphosphonate (BP) therapy. However, nowadays it has been observed with the usage of other medications, such as RANK ligand inhibitor and monoclonal antibody agent (Denosumab) and antiangiogenic drugs. Managing this condition has unfortunately proven difficult and still remains a major challenge for clinicians and surgeons.
- Response to: “Some weighing of publication rates should be used to more fairly reflect the productivity of trainees. Response to Variation in UK Deanery publication rates in the British Journal of Oral and Maxillofacial Surgery: where are the current 'hot spots'?by J. Turner, D. Hammond, M. Goodson on 24/12/2020 at 12:00 am
Thank you for your comments on our paper, as you rightly say (and this was also a feature of the original article In 20122) it would be useful to evaluate publication rates to BJOMS against number of trainees per deanery or percentage of trainees in each deanery. Such metrics may as a mathematical exercise give a more accurate representation of where trainees are being supported to write papers and engage in research or evidence based medicine. We shouldn’t forget however, that some trainees will submit papers to International and non specialty.
- Re: Assessment of surgical outcomes and oncologic safety for submental artery perforator flap reconstruction after ablation of oral cancerby K. Maharaj, M. Singh, J. Siddiqi, G.A. Ghaly on 23/12/2020 at 12:00 am
We read the paper by Shen et al with great interest.1 This paper retrospectively compared outcomes following the use of the submental island flap (SIF), submental artery perforator flap (SAPF), and the anterolateral thigh perforator flaps (ALTPF), and we commend the authors on their work. Of significance, they looked at the oncological safety associated with transferring the SIF with level 1 tissue versus SAPF not harbouring level 1 tissue.

- Latency phase in mandibular distraction osteogenesis: a systematic review in animal modelsby Tania Camila Niño-Sandoval, Ewerton Daniel Rocha Rodrigues, Belmiro C.E. Vasconcelos on 22/12/2020 at 12:00 am
The aim of the present study was to perform a systematic review of the need for the latency period in distraction osteogenesis to obtain adequate bone formation. Searches were performed in the Web of Science, Pubmed/MEDLINE, Scopus and Cochrane electronic databases. Nine articles were selected for qualitative analysis. Quality assessment was performed using the 10-item SYRCLE tool. Clinical stability was evaluated in two articles. Histology was analyzed in seven articles. Histomorphometry was analyzed in three articles and mechanical testing was used in two articles.
- Are extranodal extension and lymph node yield of pN0 to lymph node ratio useful as prognostic parameters for patients with oral squamous cell carcinoma?by Kenji Yamagata, Satoshi Fukuzawa, Fumihiko Uchida, Makiko Okubo-Sato, Naomi Ishibashi-Kanno, Hiroki Bukawa on 22/12/2020 at 12:00 am
We investigated the value of the weighted lymph node ratio (WLNR), a new marker that incorporates prognostic information regarding the number of metastatic lymph nodes (LNs) with the extranodal extension (ENE) and the lymph node yield (LNY) of pN0 patients, in the prognosis and postsurgical management of oral squamous cell carcinoma (OSCC). We designed a retrospective study and enrolled patients who were diagnosed with OSCC and treated with neck dissection (ND). The predictor variable was WLNR, and the outcome variable was overall survival (OS).
- External validation of OroGrams as a predictive model for overall and progression-free survival in Scottish patients with oropharyngeal squamous cell carcinoma: a retrospective cohort studyby A. Mentel, C.M. Douglas, J. Montgomery, J. McMahon on 21/12/2020 at 12:00 am
The aims of this study were to externally validate the OroGrams (oropharyngeal cancer survival calculator) nomogram in a Scottish cohort with high endemic smoking rates, and to compare survival rates with the original validation cohort. A retrospective cohort study in Greater Glasgow and Clyde ENT and OMFS surgery departments was performed to investigate survival outcomes of patients with oropharyngeal squamous cell carcinoma (OPSCC) from January 2012 - December 2017. The main outcome measures were progression-free (PFS) and overall survival (OS), and Kaplan Meier curves.
- Biomechanical analysis in mandibular advancement and occlusal plane rotation with finite element analysisby M.L.M. da Silveira, M.L. de Oliveira Bueno, J.S.P. da Silva, A.R. Germano on 21/12/2020 at 12:00 am
We used finite element analysis to assess stress on the cortical bone and plate fixation system, as well as mandibular resistance after sagittal split ramus osteotomy with different mandibular advancements and rotations of the occlusal plane. Three-dimensional mandibular models were obtained, and 6mm and 12mm advancements were planned associated with linear, clockwise, and counter-clockwise rotation of the angle of the occlusal plane. Each model was then fixed with one or two 2.0mm system plates and secured with four monocortical screws.
- Postoperative delirium in patients with head and neck oral cancer in the West of Scotlandby J.E. Crawford, F. Zubair, G. Baniulyte, C.J. Wales, M. Ansell, E. Thomson, S. Hislop, C. MacIver, J. Devine, J. McCaul, D. Young, J. McMahon on 20/12/2020 at 12:00 am
Our aims were to determine the prevalence and association of postoperative delirium (POD) in head and neck (H&N) cancer patients undergoing free flap reconstruction at the oral and maxillofacial surgery (OMFS) unit, Queen Elizabeth University Hospital (QEUH) Glasgow, and to assess whether these determinants can be modified to optimise patient care and reduce the occurrence of POD. Delirium remains an important problem in the postoperative care of patients undergoing major H&N surgery, and early detection and management improve overall outcomes.
- Difficult airways: a 3D printing study with virtual fibreoptic endoscopyby D. Ormandy, B. Kolb, S. Jayaram, O. Burley, P. Kyzas, H. Vallance, L. Vassiliou on 20/12/2020 at 12:00 am
Head and neck cancer patients present unique airway challenges, and oropharyngeal, laryngeal, and hypopharyngeal tumours considerably distort and narrow the anatomy of the airway. We describe the use of 3D augmented reality software combined with 3D printed models to assess the anatomy of difficult airways and to assist in the formulation of the most optimal airway management strategy in such patients. The reported patients had computed tomograms (CT) of the neck prior to their anaesthetic and surgical management.
- Modification of a face shield to allow point-of-view (POV) assisted training during the COVID-19 pandemicby T. Sato, S.N. Rogers on 19/12/2020 at 12:00 am
The COVID-19 pandemic has changed the landscape of surgical practice. It has limited access to the operating theatre due to the redeployment of theatres, staff, and equipment to support critically ill patients, and only emergency and cancer surgeries have been performed because of the risk posed by the COVID-19 infection to both patients and staff. The reduction in operating has had an adverse effect on surgical training. Opportunities for surgical trainees will remain limited and it is essential to optimise the training experience.
- Re: Dental and medical dual qualification in Oral and Maxillofacial Surgery: a global identityby B. Speculand on 19/12/2020 at 12:00 am
Oral and Maxillofacial Surgery has learnt much from the world of aviation. Mostly this has been about improving patient safety, for example by reducing stress in the operating theatre and/or reducing the rigid confines of the traditional heirachical structure in surgical teams, especially when problems arise during surgery.
- Virtual postgraduate exams and assessments: the challenges of online delivery and optimising performanceby R. Ellis, R.S. Oeppen, P.A. Brennan on 19/12/2020 at 12:00 am
The COVID-19 pandemic has catalysed the computerisation and online delivery of postgraduate examinations. Social distancing regulations and lockdown measures resulted in many written and clinical examinations being cancelled during the initial surge of the virus. In an effort to reinstate the assessment of trainees and enable career progression, the UK medical regulator, the General Medical Council (GMC) has approved unprecedented changes to clinical examinations, including virtual assessment. We outline the changes made and the advantages and disadvantages of these new examination formats.
- Insertion of a vacuum based drain for post-parotidectomy non-resolving seroma in an outpatient settingby O. Cohen, S. Gabay, A. Khafif on 18/12/2020 at 12:00 am
We describe a novel technique for the insertion of a vacuum drain, in an outpatient setting, for persistent seroma post-parotidectomy. This is a retrospective case series of a single academic centre. The complete medical records of all patients who underwent parotidectomy between 2014 and 2019 were reviewed. Data regarding demographics, comorbidities, and intraoperative and postoperative courses were extracted for patients for whom a vacuum drain was inserted due to persistent seroma. A size 8 Fr drain was inserted using a novel approach through the parotidectomy incision using ‘Biovac’ (Biometrix) 50ml, Trocar kit, that had been adjusted and modified for this purpose.
