An Algorithm for Jaw Pain among Divers.

Background: Temporomandibular disease (TMD) is commonly seen, and divers also experience pain in the temporomandibular joint (TMJ) or masticatory muscles. This article aims to provide a tool for diving physicians or medical professionals involved in diving medicine since jaw pain among divers is a pertinent subject and can be challenging to evaluate without some background in dentistry or maxillofacial surgery. Method: A basic algorithm was developed to provide a tool to differentiate jaw pains experienced by divers. Three brief case studies were developed, and five diving physicians were tasked with diagnosing the cases using the algorithm. Additionally, simple exercises and massage techniques that can benefit patients with TMD, particularly immediately after diving, are outlined. Results: All five diving physicians successfully diagnosed the cases using the algorithm. However, three of them were unable to diagnose the first case (disc luxation) without consulting the algorithm. Nevertheless, all physicians acknowledged the utility of the algorithm. Conclusions: Jaw pain in divers can stem from diverse causes, but effective treatment options exist. Our study findings provide valuable insights to assist diving physicians in making accurate diagnoses and guiding appropriate patient management, which may include referrals to specialists such as dentists, maxillofacial surgeons, or orthodontists.

Changing patterns of penetrating neck injuries at a London-based level 1 major trauma centre: a five-year review.

Penetrating neck trauma is becoming a more frequently encountered presentation in UK emergency departments. Although largely attributable to violent crime, other aetiologies are on the rise. This study aimed to review changes in the pattern of penetrating neck injury (PNI) over a five-year period at our level 1 major trauma centre. Data were retrospectively collected on all patients presenting to the emergency department with PNIs between 2016 and 2021. The number of these injuries doubled between 2016 and 2021, accounting for 11% of all penetrating trauma in 2021. The majority of patients were male (87%). Violence remained the predominant aetiology but numbers of self-harm-related PNIs trebled between 2018 and 2021. PNIs are on the rise. These injuries remain complex to manage and require a multidisciplinary approach. Tackling violent crime remains essential in combating PNIs, but focus must also be placed on identifying and supporting individuals most at risk of deliberate self-harm from a deterioration in mental health.

The Application of Cone Beam Computed Tomography (CBCT) on the Diagnosis and Management of Maxillofacial Trauma.

The assessment and management of facial trauma in an acute setting is one of the core services provided by oral and maxillofacial units in the United Kingdom. Imaging is a pre-requisite for appropriate diagnosis and treatment planning, with a combination of plain radiographs and medical-grade CT being the mainstay. However, the emergence of cone beam CT in recent years has led to its wider applications, including facial trauma assessment. It can offer multi-planar reformats and three-dimensional reconstruction at a much lower radiation dose and financial cost than conventional CT. The purpose of this review is to appraise its potential indications in all anatomical areas of maxillofacial trauma and provide our experience at a level 1 trauma centre.

Changes in Body Mass Index in Children and Adolescents with Asthma during the COVID-19 Pandemic.

Background: Increased weight gain in children during the COVID-19 pandemic has been reported. Changes in weight in children with asthma during this period have not been well described. Methods: Retrospective review of children with asthma, 6-18 years of age, seen in 2019 and 2020. Mean monthly rates of change in body mass index (BMI) were compared between years. Demographic and asthma-related factors were examined. Results: Two hundred sixty-seven patients were enrolled. BMI increased by 0.128 ± 0.283 kg/m2/month during the pandemic year as compared with 0.084 ± 0.160 kg/m2/month during the previous year (P = 0.03). Patients with baseline overweight or obesity trended toward higher rates of BMI increase than those starting with normal weight, with the greatest BMI increase occurring in the severely obese. Conclusions: In this single-site study of children with asthma, there was a greater monthly rate of BMI gain during the early pandemic as compared with that observed in the previous year.

Academic Training in Oral and Maxillofacial Surgery - when and how to enter the pathway.

Entering into surgical academia can seem a daunting prospect for an oral and maxillofacial surgery (OMFS) trainee. However, the streamlining of academic training by the NIHR to create the integrated academic training (IAT) pathway has simplified academic training and more clearly defined academic positions and entry points for trainees. In this article we review the current NIHR IAT pathway and the various grades and entry points available to OMF surgeons, both pre- and post-doctoral. We highlight the unique challenges facing OMF trainees and provide advice and insight from both junior and senior OMFS academics. Finally, we focus on the planning and application for a doctoral research fellowship - discussing funding streams available to OMF surgeons.

Isolated paediatric orbital fractures: a case series and review of management at a major trauma centre in the UK.

PURPOSE: Paediatric orbital fractures are rare. Existing literature demonstrates wide variation in estimates of incidence, aetiology, management protocols and outcomes. Despite this, it is generally acknowledged that orbital fractures with entrapment of the extraocular muscles constitute a surgical emergency due to the potential for persistent diplopia secondary to muscle ischaemia and necrosis. METHODS: This retrospective study was conducted to determine the characteristics and outcomes of management of orbital fractures amongst the paediatric population. It involved patients presenting to a major trauma unit in London between 2010 and 2020. RESULTS: Thirteen patients with isolated orbital fractures presented to our unit in this period. The average age was 13 years. Surprisingly the predominant aetiology was interpersonal violence. The most common fracture pattern involved the orbital floor and medial wall. One medial wall fracture case was missed in the emergency department. Eight patients required surgical intervention due to diplopia caused by muscular entrapment of extraocular muscles; the final patient had a large defect resulting in enophthalmos requiring a large titanium plate. A transconjuctival approach was preferred for surgical access and resorbable sheet was used in the remaining cases. Five patients had nausea, vomiting or bradycardia associated with the oculocardiac reflex. Surgical intervention occurred within 24-48 h of injury in 6 cases. Resolution of diplopia occurred in 7 patients within 6 months. CONCLUSION: Paediatric patients with orbital fractures should be assessed on the day of injury by a maxillofacial surgeon. Due to the risk of persistent diplopia, urgent surgical intervention in patients with entrapment of extraocular muscles should occur as soon as possible.

Orbital reconstruction: a systematic review and meta-analysis evaluating the role of patient-specific implants.

The purpose of this study is to execute an evidence-based review answering the following question (PICO): "Do patient-specific implants (PSI), manufactured or designed using computer-assisted technology, improve outcomes (orbital volume change, enophthalmos, diplopia, and operative duration) compared to conventional methods in orbital reconstruction following traumatic orbital injury in the adult patient population?" We performed a systematic review and meta-analysis in accordance with PRISMA guidelines. Inclusion criteria included any comparative paper whereby computer-assisted technology was used in the prefabrication or design process of implants for use in post-traumatic orbital reconstruction. Paediatric patient populations were excluded. Eight databases were systematically searched for relevant studies. Risk of bias was assessed through the NOS and RoB2 tools. Random-effects models were used to identify differences in outcomes between groups where possible. Analysis was performed using R 4.0.0. Eleven of 4784 identified studies were included, comprising 628 adult patients, with 302 and 326 patients in the patient-specific and conventional groups, respectively. Weighted mean difference between unaffected and post-operative orbital volume was 0.32 ml (SD 0.75) and 0.95 ml (SD 1.03) for patient-specific and conventional groups, respectively. Significant improvement was identified in post-operative orbital volume reconstitution with the use of PSI, compared to conventional implants, in 3 of the 5 reporting studies. Equally, post-operative enophthalmos trended towards lower severity in the patient-specific group, with 11.2% of patients affected in the patient-specific group and 19.2% in the conventional group, and operative duration was significantly reduced with the use of PSI in 3 of the 6 reporting studies. Despite a tendency to favour PSI, no statistically significant differences in key outcomes were identified on meta-analysis. Although there is some encouraging data to support improved outcomes with the use of patient-specific orbital implants in post-traumatic reconstruction, there is, at present, no statistically significant evidence to objectively support their use over conventional implants based on the currently available comparative studies. Based on the results of this study, the choice of implant used should, thus, be left to the discretion of the surgeon.

Machine learning in point-of-care automated classification of oral potentially malignant and malignant disorders: a systematic review and meta-analysis.

Machine learning (ML) algorithms are becoming increasingly pervasive in the domains of medical diagnostics and prognostication, afforded by complex deep learning architectures that overcome the limitations of manual feature extraction. In this systematic review and meta-analysis, we provide an update on current progress of ML algorithms in point-of-care (POC) automated diagnostic classification systems for lesions of the oral cavity. Studies reporting performance metrics on ML algorithms used in automatic classification of oral regions of interest were identified and screened by 2 independent reviewers from 4 databases. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. 35 studies were suitable for qualitative synthesis, and 31 for quantitative analysis. Outcomes were assessed using a bivariate random-effects model following an assessment of bias and heterogeneity. 4 distinct methodologies were identified for POC diagnosis: (1) clinical photography; (2) optical imaging; (3) thermal imaging; (4) analysis of volatile organic compounds. Estimated AUROC across all studies was 0.935, and no difference in performance was identified between methodologies. We discuss the various classical and modern approaches to ML employed within identified studies, and highlight issues that will need to be addressed for implementation of automated classification systems in screening and early detection.

Electric scooters: a quick way to get to the emergency department?

Introduction Electric scooters (e-scooters) are rife but are yet to be legalised in the UK. The aim of this paper was to investigate whether there had been an increase in the number of e-scooter injuries referred to the oral and maxillofacial surgery (OMFS) service at our unit. We present here what is, to our knowledge, the largest dataset regarding e-scooter-related injuries in the UK.Method A double cohort study in which details of patients sustaining e-scooter-related injuries that were referred to the OMFS department were collected, prospectively, for a 16-week period in 2020 (investigation period). This was compared with data collected, retrospectively, from the emergency department (ED) referral database for the same date range in 2019 (control period).Results In the investigation period, 12/649 referrals to OMFS from the ED were for e-scooter-related injuries. There were eight male patients and four female patients with a mean age of 35 years (interquartile range 24-48). Of these, only one patient was wearing a helmet and 8/12 had consumed alcohol. Head and neck injuries sustained included avulsed teeth, mandibular and midface fractures, skull fractures, facial lacerations and cervical spine injuries. One patient died as a result of their injuries. During the control period, 2/997 ED referrals to OMFS were for e-scooter-related injuries (12/649 versus 2/997; Fisher's exact test p <0.001).Conclusion There was a significant rise in e-scooter-related injuries seen at our major trauma unit compared with 2019. We recommend that e-scooters are subject to at least the same requirements in safety equipment and sobriety as bicycles and that their top speed is limited to 12.5 mph. We hope that these measures will allow the benefits of this technology to be enjoyed while reducing associated morbidity and mortality.

Debt experience and sources of funding in OMFS training: A survey of current and aspirant OMFS trainees.

Oral and Maxillofacial Surgery is unique specialty requiring dual qualification in medicine and dentistry. Since the inception of national recruitment a decade ago, only 70% of available posts have been filled. In a 2019 round, this was a worrying 30%. Questionnaires were sent to trainees at various levels via the Facebook JTG and Registrar groups. Data were collected on debt experience, and awareness of and access to financial assistance. We received 66 responses. The most important sources of funding were NHS work (46%), followed by student finance (25%). Of those surveyed, 79% were 'concerned' or 'very concerned' about debt. Respondents were interested in receiving more information on a range of sources of funding, such as non-NHS bursaries (81%), NHS bursaries (59%) and NHS work in OMFS (56%). Respondents identified the financial impact (44%), and the effect of personal and family life (41%) as the two biggest drawbacks to second-degree studies. In view of the persistent recruitment issues at the ST3 level in OMFS, it is important to address concerns surrounding second-degree study. Awareness of available support must be raised in order to safeguard the future of our specialty in its current format.

Dento-facial infections in children - A potential red flag for child neglect?

BACKGROUND: Healthcare professionals are often confronted with children presenting to the emergency department with dento-facial infections. These infections may be associated with dental neglect and as such could be a marker for general neglect. The aim of this retrospective study was to ascertain whether dento-facial infections can be used as an indicator for general neglect. METHOD: All children aged 16 years and under, who were admitted for surgical incision and drainage of dento-facial infection between January 2017 and January 2019 at King's College Hospital were examined retrospectively. All patients were discussed with the local safeguarding team/local authority to establish whether they were previously known to social services. RESULTS: This study showed that in our cohort, 48% of children admitted with dento-facial infection were already known to social services and one (2%) had been recently referred. The most commonly affected age group were 5-8-year-olds (50%) indicating that these children have an increased risk of neglect. An average of 5.6 teeth were extracted and four (10%) patients required extra-oral drainage. The average hospital stay was 2.26 days. CONCLUSION: Our retrospective study revealed that social services were already aware of 48% of patients under the age of 16, who were admitted to hospital with a dento-facial infection. This suggests a relationship between dental neglect and generalised neglect. Families of children presenting with dento-facial infection should be supported in accessing appropriate dental services for their children and clinicians should consider dento-facial infection a potential 'red flag' for generalised neglect.

A life-threatening dental implant: A case report.

BACKGROUND: Intraoral bleeding complications in implant surgery are infrequent; nevertheless, serious and life-threatening complications have been described, generally related to mandibular implants. PURPOSE: This article presents the exceptional case of a 24-year-old woman who underwent repeated delayed life-threatening episodes of intraoral bleeding following uncovering of a maxillary dental implant. Local measures afforded only temporary control. RESULTS: The episodes were successfully managed by embolising the greater descending palatine artery, and the patient remains now under close follow-up. CONCLUSIONS: Early recognition of shock secondary to hemorrhage following intraoral surgery is of paramount importance.

Demographics and management of paediatric dental-facial trauma in the 'lockdown' period: A UK perspective.

BACKGROUND: The United Kingdom entered 'lockdown' on the 23 March 2020 due to the COVID-19 pandemic. This resulted in school closures forcing children to remain at home. Dental-facial trauma was still likely to be common place due to falls and injuries exercising. The aim of this study was to explore the impact of the COVID-19 pandemic on clinical practice in a paediatric population in a tertiary care hospital and a linked Dental Institute. METHOD: A proforma was designed to capture the demographics, presenting complaints, type of dental-facial injury, treatment need and the treatment received for all paediatric patients presenting face to face with dental-facial trauma to King's College Hospital during the 'lockdown' period (23 March- 14 June 2020). RESULTS: Four hundred and twenty calls were triaged, converting to 102 patients seen face-to-face for dental-facial trauma. The remainder were able to be triaged 'virtually'. Injuries seen included 56 (54.9%) dentoalveolar injuries, 37 (36.2%) lacerations, five (4.9%) suspected facial fractures and four (3.9%) dog bites. Males and females were equally affected. The majority of incidents occurred in the home environment (n = 60, 58.8%), with the remainder (n = 42, 41.2%) occurring outside the home environment. The main causes of dental-facial trauma were falls (n = 47, 46.1%) and bicycles/scooters (n = 29, 28.4%). The most common type of dentoalveolar injury was lateral luxation (n = 15, 26.7%), followed by avulsion (n = 12, 21.4%). Only one child required treatment under general anaesthesia (GA). CONCLUSION: The demographic, presenting complaints and treatment needs of patients who presented during the lockdown period with dental-facial trauma were unusual. The overwhelming majority were able to be treated without the use of GA. The attendance protocol in a tertiary care setting and the use of 'teledentistry' ensured only the most severe trauma cases were seen. This highlights how more complex trauma can still occur during 'lockdown' and requires immediate management.

Paediatric dental pain and infection during the COVID period.

BACKGROUND: During the coronavirus pandemic, paediatric patients will still likely present with dental pain and infection. In order to streamline care at King's College Hospital (KCH), Paediatric Dentistry and Oral and Maxillofacial Surgery (OMFS) have developed a collaborative working approach allowing patients to be treated effectively and to streamline patient care in the absence of easy access to general anaesthetic facilities. METHOD: Presenting complaints, treatment need and the treatment received were recorded for all paediatric patients presenting with dental pain and infection in the "lockdown" period (23rd March- 14th June) during "normal" working hours and "out of hours" to either paediatric dentistry or OMFS. RESULTS: 420 calls were triaged which converted to 67 patients seen face-to-face for oro-facial pain and infection. 41% of children were treated successfully under Local anaesthetic alone, only 13% required a general anaesthetic (GA) in the "lockdown" period. The vast majority of patients had antibiotics prescribed prior to attendance (80%). CONCLUSION: We have demonstrated the demographic, presenting complaints and treatment need of patients who presented to KCH during the lockdown period with dental pain and infection. The majority were able to be treated without needing for GA facilities. This paper highlights how a collaborative approach between paediatric dentistry and OMFS can help streamline patient care and is a model which can be adopted by other units in the event of further "lockdowns".

Patients understanding of terminology commonly used during combined orthodontic-orthognathic treatment.

BACKGROUND: Communication between patients and clinicians plays an important role in improving quality of healthcare and clinical outcomes and ensuring that patients understand medical terminology used by their physicians is a core aspect of this. The aim of this study is to evaluate the degree of patient understanding with respect to commonly used terms in a joint orthodontic-maxillofacial clinic in the context of preparing for combined orthodontic/orthognathic treatment. METHODS: Patients were recruited to partake in a short two-part questionnaire. Demographic data collected included participants' age, sex, level of education, fluency of English and whether English was their first language. In the second part of the questionnaire, participants were asked to identify the correct definition of 11 commonly used terms from a series of multiple-choice answers. RESULTS: 51 patients participated in this study ranging between ages 15 to 52. 86% of patients selected English as their first language and 37% reported having a university education. The overall mean score for the questionnaire was 44%, with the best understood term being 'retainers' at 80% correct and 'decalcification' the worst understood at 14% correct. An association between level of education and understanding of specific terms was detected. CONCLUSION: This study highlights the overall sub-optimal patient understanding of medical terminology used by clinicians on a joint orthodontic-maxillofacial orthognathic clinic. The authors of this study recommend further consideration to the terminology currently used as well as adapting the mode and frequency of information delivery, serving to improve patients' understanding and retention of medical conversations.

Open versus percutaneous tracheostomy in COVID-19: a multicentre comparison and recommendation for future resource utilisation.

PURPOSE: The COVID-19 pandemic placed an unprecedented demand on critical care services for the provision of mechanical ventilation. Tracheostomy formation facilitates liberation from mechanical ventilation with advantages for both the patient and wider critical care resource, and can be performed using both percutaneous dilatational and surgical techniques. We compared outcomes in those patients undergoing percutaneous dilatational tracheostomy to those undergoing surgical tracheostomy and make recommendations for provision of tracheostomy services in any future surge. METHODS: Multicentre multidisciplinary retrospective observational cohort study including 201 patients with COVID-19 pneumonitis admitted to an ICU in one of five NHS Trusts within the South London Adult Critical Care Network who required mechanical ventilation and subsequent tracheostomy. RESULTS: Percutaneous dilatational tracheostomy was performed in 124 (62%) of patients, and surgical tracheostomy in 77 (38%) of patients. There was no difference between percutaneous dilatational tracheostomy and surgical tracheostomy in either the rate of peri-operative complications (16.9 vs. 22.1%, p = 0.46), median [IQR(range)] time to decannulation [19.0 (15.0-30.2 (5.0-65.0)] vs. 21.0 [15.5-36.0 (5.0-70.0) days] or mortality (13.7% vs. 15.6%, p = 0.84). Of the 172 patients that were alive at follow-up, two remained ventilated and 163 were decannulated. CONCLUSION: In patients with COVID-19 pneumonitis that require tracheostomy to facilitate weaning from mechanical ventilation, there was no difference in outcomes between those patients that had percutaneous dilatational tracheostomy compared with those that had surgical tracheostomy. Planning for future surges in COVID-19-related critical care demands should utilise all available resource and expertise.
