Justifying the implementation of intraoperative computed tomography for midface fracture treatment in improving outcomes.

Intraoperative CT scanning is the international standard for treating midface fractures as it allows intraoperative assessment of reduction and fixation. To our knowledge, no NHS hospital in the UK has this facility yet due to the financial and logistical burden of its implementation. The aim of this study was to determine if complications including the requirement for a return to theatre (RTT) could have been predicted from the post-fixation CT scan. All treated midface fractures that had presented to a regionalised major trauma centre within two years (01 January 2020 - 31 December 2021) were identified. Those developing complications including RTT were determined. All postoperative CT scans (including those without complication or RTT) were re-analysed with the clinicians blinded to the outcomes to determine the positive predictive value (PPV) and negative predictive value (NPV) of requiring RTT to alter plate position intraoperatively based on CT scan alone. In all, there were eight episodes of unplanned return to theatre, resulting in an overall RTT rate of 8/119 (6.7%). When only analysing patients treated for orbital fractures this RTT rises to 8/40 (20%). Of those eight patients who had a postoperative CT and required RTT, this could have been predicted in 7/8 (87.5%). A total of 16/44 (36.4%) patients that did not have RTT would have additionally been recommended to have the plate position altered based on CT alone. Based upon those that had a CT, the PPV of CT alone being able to predict those requiring RTT was 40.6% and the NPV 96.2%. Our results would suggest intraoperative CT would likely have prevented eight patients requiring RTT in two years and could have improved outcomes in 16 cases. In preventing RTT as well as potentially improving the outcomes of a further 16 cases in maxillofacial surgery, the purchase of an intraoperative CT scanner could yield net savings of £75534-£114990 over two years.

Non-surgical management of non-condylar mandibular fractures.

Unlike fractures of the remaining facial skeleton, fractures of the non-condylar part of the mandible are invariably treated surgically, with the potential risk of further iatrogenic injury. There is, however, a substantial evidence gap pertaining to the potential non-surgical management of such injuries. The aim of this study was to determine the outcomes of mandibular fractures treated with non-surgical management. All patients with mandibular fractures who were referred to a large regional major trauma service over a one-year period (1 January-31 December 2021) were identified. Those treated with surgery or who sustained fractures of the condylar portion of the mandible were excluded. Of all the patients referred to our unit with mandibular fractures, 34/155 (22%) underwent non-surgical management. In all cases plain radiographs demonstrated minimal displacement. Thirty-two (94%) fractures were unilateral, of which 24 (70%) involved the angle. Two of 34 patients subsequently required open reduction and internal fixation due to pain that did not improve over time, one of whom declined. A minimally extruded tooth in the fracture line, which altered the occlusion in one additional patient, required minimal reduction of the enamel. The remaining patients healed without complication six weeks after injury. Non- surgical management requires careful case selection and regular follow up, so is of value to only a small proportion of patients. Twenty-two per cent of all mandibular fractures were managed non-surgically at our unit in one year, with a 97% success rate, demonstrating the potential utility of this strategy in carefully selected cases.

Retropharyngeal lymph node metastasis in oral cancer. Systematic review and survival analysis.

INTRODUCTION: Metastasis to retropharyngeal lymph nodes (RPLN) from oral squamous cell carcinoma is rare and associated with poor outcomes. The poor prognosis of RPLN is multifactorial and includes the clinicopathological aggressiveness of the primary disease and the late presentation. The aim of this systematic review is to assess the evidence on RPLN in patients diagnosed with oral squamous cell carcinoma (OSCC), the quality of the diagnostic modalities and the available treatment options. We aimed to analyse the overall survival of these patients diagnosed with RPLN. METHODS: A systematic review was undertaken according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines. The initial literature search generated 289 articles. A total of 11 papers satisfied our criteria. Eight papers provided enough data to perform survival analysis and 3 papers compared the diagnostic modalities used in the detection of RPLN. RESULTS: A total of 73 OSCC patients diagnosed with RPLN metastasis were identified. The most common primary tumour subsites included the tongue (20), buccal mucosa (15) and gingiva (11). The cumulative 5-year OS rate was 17.8% while the 2-year overall survival was 35.9%. CONCLUSION: The presence of nodal metastasis is an independent prognostic factor in head and neck cancer. In this study, RPLN metastasis had a poorer prognosis (5 years overall survival is 17.8%) when compared to the survival rate of oral cancer without RPLN metastasis (5 years overall survival is 40%). There was no statistically significant difference between the overall survival in primary RPLN metastasis and recurrent RPLN disease.

Effectiveness of Kinesio Taping and Exercises for Pronated Feet in Children with Neurodevelopmental Disorders: A Cross Over Study.

BACKGROUND: Taping is widely used intervention in various conditions treated by physiotherapist. Neurodevelopmental disorders in children leading to foot abnormality is one of the major concen. As taping is one of the intervention in same the study is focusing taping on pronated feet in the selected age group. AIM: The aim of this study was to investigate whether the kinesiotaping and exercise improve pronated feet in neurodevelopmental disordered (NDD) children. PATIENTS AND METHODS: This was a cross over study, within subjects study evaluating two treatments, kinesio tape, and exercise. Thirty subjects with age group 6-12 years diagnosed with NDD having pronated feet. Subjects were allocated in the two groups. Group 1 included subjects for taping and Group 2 included subjects for exercise. Taping was applied for two consecutive weeks for 5 days per week and then 2 weeks of the window period, which was followed by two consecutive weeks of exercise sessions for 5 days per week. The navicular drop test and Foot Posture Index were measured pre and post treatment. Foot posture index used to examine the posture of foot and navicular drop test. RESULTS AND CONCLUSION: Group 1 (taping) and Group 2 (exercises) showed no significant results as a single entity, whereas there was a small effect seen of the intervention.

Printed titanium implants in UK craniomaxillofacial surgery. Part II: perceived performance (outcomes, logistics, and costs).

This second part explores perceptions and understanding of clinical performance, turnaround, and costs for printed titanium implants or plates in common procedures, evaluating both 'in-house' and 'outsourced' CAD-CAM pathways. A cross-sectional study, supported by the British Association of Oral and Maxillofacial Surgeons (BAOMS) and a national trainee-led recruitment team, was conducted over 14 weeks. A total of 132 participants took part (demographic data is reported in Part I). For fibular-flap mandibular reconstruction, most participants (69% - 91%) perceived printed titanium as superior to intraoperatively or preoperatively hand-bent plates for surgical duration, accuracy, dental restorability, and aesthetics. There was less agreement about complications and plate-failure risks. Most perceived printed plates to be superior to traditional wafer-based maxillary osteotomy for surgical duration (61%) and maxillary positioning (60%). For orbital floor repair, most perceived improvements in surgical duration (83%, especially higher-volume operators p=0.009), precision (84%), and ease of placement (69%). Rarely (less than 5%) was any outcome rated inferior to traditional techniques for any procedure. Perceived turnaround times and costs were variable, but the greatest consensus was for two-segment fibular-flap reconstructions and orbital floor repair. Industry estimates were generally consistent between two company representatives, but manufacturing-only costs differed when using in-house (departmental) designers. Costs and turnaround times are questionable barriers since few understand 'real-world' figures. Designing in-house can dramatically alter costs. Improved accuracy and surgical duration are common themes but biomechanical benefits are less-well understood. This study paints a picture of the potentially routine applications and benefits of printed titanium, capacity for uptake, understanding amongst surgeons, and areas for improvement.

Printed titanium implants in UK craniomaxillofacial surgery. Part I: access to digital planning and perceived scope for use in common procedures.

This first part of a two-part study examines perceived applications for and barriers to using printed titanium in light of current caseloads, funding pathways, and use of digital planning. It aims to demonstrate the scope for printed titanium in modern practice and to guide industry about the needs of UK surgeons. A cross-sectional study over 14 weeks was performed electronically with support from the British Association of Oral and Maxillofacial Surgeons (BAOMS) and a national trainee-led recruitment team. Ethics approval was obtained at the lead centre. A total of 132 participants joined the study (70% consultants, 25% specialty registrars, and 5% other), approximating a 29% response rate from consultant/registrar BAOMS members throughout mainland UK. Eighty-eight per cent used CAD-CAM design, with highly variable funding/access, design/manufacturing workflows (in-house/outsourced). Eighty-eight per cent were involved with trauma, 61% with orthognathic, and 52% with oncology-reconstruction surgery. Favourite applications for printed titanium were orbital floor repair (89%) and free-flap jaw reconstruction (87%). Most participants also cited maxillary/zygomatic osteotomies and cranioplasty (range 61%-73%). Although a popular application (78%), the evidence base in temporomandibular joint surgery is limited. Those performing orthognathic surgery perceived more indications than those who did not (p=0.013). Key barriers included cost, turnaround time and logistics, and the need to be trained in traditional techniques. Printed titanium was useful for both common and niche procedures, but was specifically limited in emergency trauma. Most surgeons had experience in CAD-CAM surgery but technical understanding appeared unclear. Limiting factors included variable funding and production pathways, perceived costs, and logistics, but in-house design can minimise them. In part II, we quantify perceived benefits and limitations and whether surgeons' understanding and knowledge are sufficient to rationalise them.

The future of OMFS lies in creating pathways to implement the PMETB recommendations and inspiring our trainees. Enough time has been spent debating, we need to deliver!: Re: Newman L, Brown J, Kerawala C, et al. Our specialty. The future. Is the writing on the wall? Br J Oral Maxillofac Surg 2020 (online ahead of print).

The British Association of Oral and Maxillofacial Surgeons (BAOMS) has been at the centre of the transition of our specialty in the UK from a branch of dentistry to one of the 10 UK surgical specialties. In this role it has, at different times, pushed boundaries against resistance from other specialties, and redirected the ambitions of the deputy chair of the Postgraduate Medical Education and Training Board (PMETB) review to produce recommendations that were exactly what OMFS needed. The editorial Our specialty. The future. Is the writing on the wall? is just the most recent iteration of half a century of internal debate. Whilst there are some issues with how the authors have presented recruitment data (their figures omit ST1 run-through and do not recognise that the same single, unfilled post may be present for two or more national selection rounds) their first paragraph A debate that we feel is long overdue presents the greatest concern. In this short communication, we illustrate that in the last 20 years the specialty has not been short of debate. In the absence of new and specific evidence that any other route forward would be supported by our national training committee (OMFS SAC), our regulator (GMC), the breadth of our specialty (including our current specialists and our current and future trainees) and, most importantly, would actually address our problems, we should avoid putting energy into an empty debate. Our focus should be on delivering the PMETB recommendations and inspiring our future trainees.

Changing the Oral and Maxillofacial Surgery (OMFS) training pathway in the United Kingdom - an illustrative retrospective.

OMFS training is perceived as a long and expensive pathway although papers have shown it compares favourably with other surgical specialties. Every OMFS clinician has a vested interest and duty continually to improve the quality of training and minimise costs, especially to trainees at junior levels. Any serious proposal to fundamentally change the format of training, must be given due consideration by all stakeholders. In 2016, a British Medical Journal article whose authors included the BAOMS President of that year and OMFS Specialty Advisory Committee (SAC) Chair, posed the question - should the future of OMFS training revert to single dental degree, change to single medical degree - or continue as a dual degree specialty? The BMJ publication was discussed at the British Association of Oral and Maxillofacial Surgeons (BAOMS) Council in March 2016 and all present unanimously supported the dual degree pathway. Later that year a formal proposal was made by the BAOMS immediate past President that training in the UK change to single medical degree 'Maxillofacial Surgery' similar to the training in Spain, France or Italy. Evidence around the risks and benefits of making this change to OMFS training was assembled and reviewed by BAOMS Council in March 2017. BAOMS Council once again unanimously supported continuing OMFS as a dual degree specialty with the observation that the quality of patient care which this training provided was the specialty's Unique Selling Point or USP. The requirement for both degrees to provide care for OMFS patients had been confirmed by external scrutiny on two separate occasions by the responsible regulators. In this paper, we outline the key steps to be considered when making major changes in the OMFS training pathways using this event as an example and the suggestion that those proposing changes should assemble and present evidence to support their proposal using the template provided.

Storiform collagenoma (sclerotic fibroma) of the oral mucosa.

Storiform collagenoma (also called sclerotic fibroma) is uncommon, occurs as a cutaneous fibrous neoplasm, and is particularly rare in mucosal tissue in the head and neck. We describe an unexpected diagnosis in the oral cavity. Histopathological examination showed a proliferation of fibrous tissue, which was well circumscribed but unencapsulated, with thick laminated bundles of eosinophilic collagen that exhibited a storiform or "whorled" pattern. First described by Weary et al in 1972, storiform collagenoma is a marker for Cowden's disease or PTEN hamartoma tumour syndrome. Identification of other synchronous lesions should prompt chromosomal analysis for a mutation in the PTEN gene on chromosome 10q23.

Results of flap reconstruction: categorisation to reflect outcomes and process in the management of head and neck defects.

The reporting of the outcomes of flap reconstruction is often based on numerical success rates. Whilst this remains a useful variable with which to measure success, it is limited in its ability to reflect the complex processes involved. The lack of consistency in the categorisation of outcomes of flap reconstruction in the head and neck could potentially lead us to lose the opportunity to fully capture the implications of its success or failure, or both. We propose a classification that moves away from primarily reporting the results of its binary nature, and focuses more on the process of reconstruction, particularly in the head and neck.

Pneumatic tourniquets in maxillofacial surgery: do we need to change practice? A national study.

The use of pneumatic tourniquets during the harvest of free flaps is an established practice in oral and maxillofacial surgery. Their use can be associated with severe but preventable complications, for which operating surgeons are ultimately responsible. The aim of this study was to find any pitfalls concerning the safe use of tourniquets by maxillofacial surgeons. An electronic questionnaire based on the Association of Perioperative Registered Nurses (AORN) guidelines was distributed to maxillofacial surgeons nationally. A total of 37 questionnaires were completed and analysed. The mean (range) score for the knowledge-based questions for all respondents was 72.8% (47.3%-94.7%). The number of clinicians who answered correctly on topics relating to cuff position, reperfusion time and contraindications for the use of tourniquets were 15, 10 and 6, respectively. A total of 35 clinicians had had no formal training on the application of a tourniquet. Our study shows that knowledge about their use by maxillofacial surgeons is poor, and it highlights the importance of formal education during basic and higher surgical training.

Radial forearm free flap as the last resort for oesophageal reconstruction.

Strategies for oesophageal reconstruction following resection vary according to the nature of the pathology encountered, patient factors and surgeon preference. However, reconstruction in patients with multiple previous failed attempts poses specific management challenges. We present the case of a 61-year-old man who underwent oesophageal reconstruction with a radial forearm flap as a last resort.

Is a fractured mandible an emergency?

We retrospectively audited the records of 708 patients who presented with the diagnosis of fractured mandible between January 2009 and July 2013 at the Queen Elizabeth Hospital, Birmingham. We assessed the different factors that may have altered their outcomes, and found that delay before definitive fixation caused no harm in either the short or the long term.

Prescription of antibiotics: does it alter the outcome for patients who have fractures of the angle of the mandible?

We retrospectively studied 708 consecutive patients at the Queen Elizabeth Hospital, Birmingham, to find out whether one of the four antibiotic protocols in use conferred any advantage (or disadvantage) on a patient who had a fractured angle of the mandible, and there was none. However, the time from initial injury until the time of the first dose of antibiotic was important. Clinically, if patients waited more than 72hours after the injury before the first dose of antibiotic was given, they had a three times higher rate of postoperative infection than patients who were given their first dose between 24 and 72hours after the injury. Morbidity was more than five times higher during the postoperative period if the patient had waited for three days before their first dose, compared with those given the first dose within eight hours of injury. The overall rate of malunion or non-union of the fracture was between five and 10 times higher if the patient had waited more than 72hours after injury compared with all the other groups. There was a considerable difference in cost between the intravenous and oral versions of the antibiotics used (Augmentin® and metronidazole) so, if it could be shown that the oral doses are as efficacious as intravenous doses, a great deal of money could be saved.

Craniofacial implants at a single centre 2005-2015: retrospective review of 451 implants.

Craniofacial endosseous implants are regularly used to support prostheses in the rehabilitation of complex defects, but reported success rates vary. To review our own clinical practice over 10 years, and particularly to examine the impact of radiotherapy and the timing of placement on the survival of implants, we retrospectively audited the records for all patients who had endosseous implants for prosthetic rehabilitation in our unit between 2005 and 2015. We reviewed 167 records, which gave 451 implants, of which, 222 (49%) were auricular, 98 (22%) nasal, and 131 (29%) orbital. Most were placed after ablative operations for cutaneous malignancy (n=103 patients, 62%). The failure rate of implants placed in bone that was irradiated either before or after placement was significantly higher than that of those placed in non-irradiated bone (univariate analysis: 11% compared with 2%, p<0.001: Kaplan-Meier survival analysis: p<0.001). The timing of placement in relation to radiotherapy (before compared with after) seemed to have no impact on success (p=0.96). Our findings are in keeping with previous reports, and the principal observation is that radiotherapy adversely affects success. We work closely with our maxillofacial prosthetists and place implants at the time of ablation. Our findings seem to support this practice regardless of whether or not the patient will later require adjuvant radiotherapy.
