Publication Model: Ahead of Print Abstract: Introduction: Recent evidence suggests that acute emergency management of mandible fractures does not improve surgical outcomes yet is associated with increased financial burden. Current NHS policy advocating for increased adoption of day-case and semi-elective surgical procedures to reduce bed strain must be balanced with providing timely, effective treatment. Our research aims to determine patient groups currently managed via semi-elective admission and whether this can be extended to other groups to provide safe and effective management of mandible fractures. Methods: A multi-national trainee-led audit of mandibular fractures across 49 units was completed by the Maxillofacial Trainee Research Collaborative (MTReC). Each unit prospectively collected data on fractures on admission and at follow-up. Data collected included patient demographics, behaviour, health, injury, timing to intervention and surgical complications. Results: Data were collected on 947 mandibular fractures. Of the surgically managed patients, 649 (90%) were managed via acute emergency admission at the time of presentation, while 68 (10%) were managed semi-electively. Patient demographics, injury pattern and mechanism appeared to significantly affect timing of management, whereas patient behaviour, health status, timing of injury and presentation did not. Semi-elective management was associated with a significantly shorter inpatient duration (0.9 versus 1.9 days, p =0.000) with no differences in readmission, antibiotic usage or surgical complications ( p =1.000, RR 1.030). Conclusion: Our study demonstrates the efficacy of planned admissions and semi-elective management of mandibular fractures. Simple mandibular fractures in compliant patients are suitable for semi-elective treatment. Holistic patient assessment and tailored surgical planning is crucial in determining admission modality to effectively manage mandibular trauma. Full text available here

Source: Oral and maxillofacial surgery [Oral Maxillofac Surg] 2022 Jul 05. Date of Electronic Publication: 2022 Jul 05. Abstract: Introduction: Complications following mandibular fractures occur in 9-23% of patients. Identifying those at risk is key to prevention. Previous studies highlighted smoking, age and time from injury to presentation as risk factors but rarely recorded other possible confounders. In this paper, we use a collaborative snapshot audit to document novel risk factors and confirm established risks for complications following the treatment of mandibular fractures. Methods: The audit was carried out by 122 OMFS trainees across the UK and Ireland (49 centres) over 6 months, coordinated by the Maxillofacial Surgery Trainees Research Collaborative. Variables recorded included basic demography, medical and social history, injury mechanism and type, management and 30-day outcome. Results: Nine hundred and forty-seven (947) patients with fractured mandibles were recorded. Surgical management was carried out in 76.3%. Complications at 30 days occurred 65 (9%) of those who were managed surgically. Risk factors for complications included male sex, increasing age, any medical history, increasing number of cigarettes smoked per week, increasing alcohol use per week, worse oral hygiene and increased time from injury to presentation. Discussion: We have used a large prospective snapshot audit to confirm established risk factors and identify novel risk factors. We demonstrate that time from injury to presentation is confounded by other indicators of poor health behaviour. These results are important in designing trial protocols for management of mandibular fractures and in targeting health interventions to patients at highest risk of complications.

Abstract: The lip-split mandibulotomy (LSMA) is an access procedure that has been used in head and neck (H&N) surgery as an aid to surgical resection of inaccessible tumours of the postertior oral cavity and oropharynx. Anecdotal evidence suggests that it has significant morbidity. Voices of concern within the H&N surgical community suggest that it has been abandoned in favour of technological advances such as robotic surgery. We report here the first (to our knowledge) registered systematic review of its kind, documenting the safety and efficiency of LSMA in H&N surgery. We performed a PRISMA-guided systematic review (PROSPERO-registered) and identified reports using a search algorithm in MEDLINE/EMBASE. LSMA-related surgical complications were recorded using the Clavien-Dindo classification. Secondary outcomes included swallowing dysfunction, facial cosmesis, and patient satisfaction recorded in health-related quality of life questionnaires (HRQoL). From 125 studies identified, 54 met the inclusion criteria (3872 patients). The LSMA mortality rate was 0%; we did not identify a single case of perioperative death. The median rate of osteoradionecrosis was 5.4%, whereas fistula formation was 5.7%. Malunion was noted in 4.9%. Other complications (surgical site infection, plate exposure) were around 5%. There was significant between-study variation with regards to swallowing assessment tools, but overall there was no significant difference in outcomes. This was also the case for the HRQoL questionairres. LSMA is a safe procedure with an acceptable rate of complications, and should definitely remain in the armamentarium of H&N surgery.

Abstract: The incidence and management of maxillofacial trauma was compared between the first and third lockdowns in the United Kingdom due to the COVID-19 pandemic. From 6 January, 2021 to 8 March 2021, the units that had participated in the collection of data during the first lockdown were asked to update their information into the same database for the third. Nine units participated with 929 entries. Compared to the first lockdown, the number of patients whose treatment had been changed due to the pandemic reduced from 7.6% to 0.4% in the third lockdown. In the UK during the third lockdown there were higher numbers infected with COVID-19 and admitted to hospital than in the first lockdown. Despite this OMFS units that participated in the second study were able to continue the management of maxillofacial trauma without the pandemic affecting care.

Abstract: Traditionally, surgical management of zygomaticomaxillary complex (ZMC) and orbital fractures occurs within two to three weeks of the injury, followed by an overnight admission to allow for extended eye observations. This is due to the risk of postoperative retrobulbar haemorrhage (RBH) or orbital compartment syndrome (OCS), a rapidly progressive and sight threatening emergency that requires immediate intervention. In September 2016 the oral and maxillofacial surgery (OMFS) department at Leeds Teaching Hospitals redesigned their trauma service with a full-time trauma consultant, a dedicated clinic, and a weekly morning elective trauma theatre list. This allowed for standardisation of the management of patients with OMFS injuries. Furthermore, a formal day-case ZMC and orbital fracture pathway was developed to allow patients to undergo surgical management of such fractures with a same-day discharge. This has since been identified as an area of excellence by the Getting It Right First Time (GIRFT) programme, and is in line with the addition of ZMC and orbital fractures to the procedural list written by the British Association of Day Case Surgery (BADS). Unbeknown to the unit, the volume of day-case procedures was the highest within the UK, demonstrating the importance of GIRFT in highlighting areas of good or unique practice. The aim of this study was to determine the impact of our day-case pathway and designated OMFS trauma service on compliance with recent recommendations by GIRFT and BADS. Secondly, it was to determine the safety of same-day discharge with regards to postoperative complications. Request this item Authors: Kumar, D., Dawoud, B.E.S.; Kent, S.; MTReC; Kyzas, P.
Source: British Journal of Oral & Maxillofacial Surgery; Apr2022, Vol. 60 Issue 3, p291-294, 4p Abstract: Non-condylar mandibular fractures are consdered 'open' fractures and as such are thought to require prophylactic antibiotics. There is no overall consensus on the optimal regimen or choice of antibiotic in the preoperative and postoperative periods due to a lack of high-quality evidence. We therefore set out to ascertain the current UK-wide practice of antibiotic prescribing for non-condylar mandibular fractures. We used a web-based online survey (Google Forms) that was disseminated via email and social media platforms to oral and maxillofacial surgery (OMFS) consultants and trainees of all grades. The questions focused on usual antibiotic practices and typical clinical management of non-condylar mandibular fractures. We gathered information on preoperative antibiotics, and on perioperative and postoperative periods. We collected data from 50 different UK OMFS units representing a broad snapshot of national practice. The majority of responders were speciality trainees (36%) followed by dental core trainees (34%). A total of 45/50 centres routinely admitted patients, and preoperative intravenous antibiotics were commenced on admission by 77/89 respondents, intravenous being the chosen route in all cases. In the preoperative period 81% prescribe co-amoxiclav. In 91% of cases, open reduction and internal fixation (ORIF) was on general emergency (CEPOD) operating lists, whilst dedicated OMFS trauma lists accounted for 9%. With respect to timing, 49% aimed to carry out ORIF within 24 hours from the time of admission, 44% aimed for surgery within 24 - 48 hours, and 6% aimed for surgery on a semielective basis (48 hours or more). Postoperative antibiotics were prescribed routinely by 88% of responders. Preoperative intravenous prophylactic antibiotics are commonplace in non-condylar mandibular fractures. This UK-wide survey demonstrated significant variability in antibiotic prescribing practices, especially in the postoperative period. Most units still rely on CEPOD emergency theatres to provide the capacity for ORIF in this patient group Request this item Authors: Kyzas P

Source: Journal of Cranio-Maxillofacial Surgery; Jun2022, Vol. 50 Issue 6, p485-492, 8p Abstract: The aim of this report is to introduce the use of the dermal substitute Integra® in the context of free fibula flap prelamination for mandibular reconstruction. Three cases of mandibular reconstruction with prefabricated and Integra-prelaminated vascularized fibula flaps are reported in this article. The patients reported in this case series presented with the following tumours: an extensive cemento-ossyfying fibroma, a multicystic ameloblastoma and an extensive calcifying epithelial odontogenic tumour. Virtual three-dimensional (3D) planning and 3D-printed cutting guides were used for the mandibulectomies, the flap harvest and the positioning of the implants. The dermal substitute Integra was used for prelamination instead of skin grafts. Treatment of all 3 patients was performed in two stages; the first consisted of the fibula prefabrication (dental implant insertion) and prelamination, and the second consisted of tumor resection and reconstruction with the vascularized implant-bearing fibula flap. Integra was shown to be able to generate complete mucosa-like tissue over the fibula flaps and in the peri-implant areas. The patients have been followed up for 1, 3 and 7 years, respectively, with satisfactory prosthetic, functional and aesthetic results. None of the patients developed peri-implant disease. It was observed that prelamination with the dermal substitute Integra leads to development of mucosal lining with clinical features similar to oral mucosa. In this report of three cases, use of Integra as part of the prelamination and prefabrication process, instead of skin grafts, appears able to clinically generate mucosal lining with avoidance of skin grafts Request this item Author(s) Puglia F.A.; Hills A.; Dawoud B.; Magennis P.; Chiu G.A. et al.

From 1 April 2020 until 31 July 2020, OMF surgery units in the UK were invited to prospectively record all patients presenting with OMF trauma. Information included clinical presentation, mechanism of injury, how it was managed, and whether or not treatment included surgery. Participants were also asked to compare the patient's care with the treatment that would normally have been given before the crisis. Twenty-nine units across the UK contributed with 2,229 entries. The most common aetiology was mechanical fall (39%). The most common injuries were soft tissue wounds (52%) and, for hard tissues, mandibular fractures (13%). Of 876 facial fractures, 79 patients' treatment differed from what would have been normal pre-COVID, and 33 had their treatment deferred. Therefore the care of 112 (14%) patients was at variance with normal practice because of COVID restrictions. The pattern of OMFS injuries changed during the first COVID-19 lockdown. For the majority, best practice and delivery of quality trauma care continued despite the on-going operational challenges, and only a small proportion of patients had changes to their treatment. The lessons learnt from the first wave, combined with adequate resources and preoperative testing of patients, should allow those facial injuries in the second wave to receive best-practice care.

We analysed odontogenic cervicofacial infections (CFI) presenting to oral and maxillofacial surgery (OMFS) departments during the first wave of COVID-19 in the United Kingdom. From 1 April 2020 until 31 July 2020 a database was used to prospectively collect records for all patients with CFI who presented to oral and maxillofacial teams. Information gathered included clinical presentation, location/origin of infection, and how this was managed. The OMFS units were asked to compare the patient's care with the treatment that would usually have been given prior to the crisis. A total of 32 OMFS units recorded 1381 cases of CFI in the UK. Most of the infections were referred via the emergency department (74%). Lower first or second molars were the most common origin, contributing 40% of CFI. Collaborators reported that patients' treatments were modified as a response to COVID in 20% of cases, the most frequently cited reason being the application of COVID-19 hospital policy (85%). The impact of the first wave of COVID modified the management of a significant number of patients presenting with CFI, and there was a proactive move to avoid general anaesthetics where possible. Some patients who presented to secondary care were given no treatment, suggesting they could have been managed in primary dental care if this had been available. We recommend that OMFS units and urgent dental care centres (UDCCs) build strong communication links not only to provide the best possible patient care, but to minimise COVID exposure and the strain on emergency departments during the pandemic.

The aims of this pilot project were: to evaluate feasibility of the questionnaires developed for the audit and how effective they were with regards to quality improvement, to test the processes associated with the data collection system and finally, to provide baseline data to support patient data collection without the requirement of prospective consent. The pilot included a series of six audits (oral and dentoalveolar [ODA], oncology, orthognathic, reconstruction, trauma, and skin). Data entry was clinician-led in five OMFS units and in one unit (EKHU), it was additionally supported by members of the clinical coding team. One hundred and twenty-eight REDCap account user details were issued and of these, 45 (35%) completed registration and 22 (17%) were active users who participated in the pilot data entry. Disproportionate focus on individual audits within QOMS was seen, though not all units offered the full range of service audited. Users suggest the skin and ODA audits were sufficiently clear, but improvement is required in the oncology and reconstruction questionnaire particularly. The pilot was successful in aiding the project team identify areas of weaknesses and strength in the design of the REDCap registry and implementation of the next phase of the initiative. The information and experience gained has to date enabled a successful application for section 251 approval from the HRA and progress for the next phase of national data collection.Copyright © 2021 Author(s) Adam D.; Broderick D.; Kyzas P.; Vassiliou L.

However, literature on arterial MACD is conflicting. We report, to our knowledge, the first registered systematic review of its kind to evaluate the safety and efficiency of arterial MACD in free flaps. We performed a PRISMA-guided systematic review (PROSPERO-registered) and identified reports using a search algorithm in MEDLINE/EMBASE. The rate of arterial thrombosis was set as the primary outcome. Secondary outcomes included flap survival, failure rates, and comparison of MACD and the conventional hand-sewn technique. From the 17 studies identified, 2672 free flap reconstructions were performed and 640 arterial anastomoses with MACD attempted (622 completed, 97.2%). The pooled incidence of arterial thrombosis was 2.1% (13/622), and overall flap failure rate 4.34% (116/2672). The total number of arterial MACD procedures performed first time, with no perioperative complications, revisions, or thrombosis, was 88.9% (569/640). Grading of Recommendations, Assessment, Development and Evaluation (GRADE) quality analysis revealed low quality and significant heterogeneity. The use of arterial MACD is a safe and efficient alternative to hand-sewn anastomosis, with more recent literature showing excellent results. However, further evaluation is required with controlled trials.Copyright © 2020 Author(s) Gray W.K.; Day J.; Morton M.

One solution is to send the patient home and admit them as an elective patient at a later date. The aim of this study was to investigate the outcomes of patients admitted directly and those seen as elective patients following fracture of the mandible or zygomatic complex. Data were taken from the hospital episodes statistics (HES) dataset for 2011-2018, and all hospital admissions for mandibular and zygomatic complex fractures within the National Health Service (NHS) in England were extracted. Patients were categorised as those admitted on attendance at the emergency department and given definitive treatment during the admission, and those not admitted on attendance at the emergency department but discharged home and seen as elective admissions within 30 days of attendance. Data were available for 39 606 patients. For both types of fracture there was substantial variation between NHS trusts in the proportion of patients admitted electively and the proportion admitted directly as emergencies. Elective admission was independently associated with shorter overall stay and lower emergency readmission rates. We found no evidence that delays to definitive surgery through elective admission had a negative impact on emergency readmission rates. Patients admitted electively had a significantly shorter hospital stay.Copyright © 2020 Author(s) Gray W.K.; Day J.; Morton M.

Source British Journal of Oral and Maxillofacial Surgery; Oct 2020; vol. 58 (no. 8); p. 898-917 Oral cancer is referred to specialists by both general practitioners (GPs) and dentists, with varying proportions reported in different studies. However, some have noted that dentists more commonly refer oral cancer in the absence of patient-perceived symptoms and may refer at an earlier stage. Unfortunately, approximately half the UK adult population do not receive regular dental care. We have conducted a systematic review of studies that compare GPs and dentists in the referral of oral cancer and have focused on three aspects: the proportion of diagnosed oral cancers, stage on presentation, and delay. Searches of the databases Medline, Embase, Scopus, Google Scholar, Web of Science, and CINAHL, together with additional searches of reference lists, authors, and conference proceedings, found 22 studies from 10 countries, which included a total of 4953 oral cancers. The percentage of medical referrals ranged from 13% to 86%; dental referrals ranged from 15% to 80%. Random-effects meta-analysis indicated a combined relative risk of medical referral to dental referral of 1.36 (95% CI: 0.99 to 1.86). For UK-based studies, the relative risk was also 1.36 (95% CI: 1.05 to 1.76). There was considerable heterogeneity for all studies and for a subgroup of UK studies: I296.4% (95% CI 95.4 to 97.1) and 81.0% (95% CI 63.3 to 90.1), respectively. Several studies showed a lower stage for dentally-referred cancers; the combined risk for dentists and GPs referring early (stages 1 and 2) disease was 1.37 (95% CI: 1.17 to 1.60), and one cause may be the much higher number of cases referred by dentists in the absence of symptoms. No studies showed a significant difference in delay. Oral cancer is referred by both GPs and dentists, typically about 50% and 40%, respectively, although there is a wide range, probably depending on local circumstances. Both groups require skills in oral examination, recognition of lesions, and knowledge of the risk factors. Effectively, regular dental attenders are a select group that is regularly screened for oral cancer, and it is likely that screening is not delivered to those with the highest risk. We suggest that further work is required on how to access high-risk individuals both for possible screening and preventive interventions.Copyright © 2020 The British Association of Oral and Maxillofacial Surgeons Author(s) Hasan A.; De Gea Rico A.; Cousin G.

The aim was to assess a single surgeons performance in NMHNSC excisions over five years. We analysed time and case number to reach a consistent competency with regards to excision margins. Materials/Methods Skin pathology data sets were collected retrospectively from 2014 to 2018 The data collected involved a single surgeon operating in multiple hospitals and settings. Information regarding patient demographics, histological features of NMHNSC and excision margins were collected from pathology reports for each operation. Results/Statistics The results showed from January 2014 to April 2014 there was a 6.8% involved margin rate and a 11.4% close margin rate. This improved with further case volume over the five years. By September2018 to December 2018it was noted that the involved margin rate had reduced to 3.8% and the close margin rate had increased slightly to 13.4%. We present the longitudinal statistics. Conclusions/Clinical relevance This study has shown that there appears to be improvement in performance of excisions of NMHNSC as the surgeon gains experience over time to reach a consistent performance. There was a clear initial learning curve to achieve this which took several cases. This likely differs from numbers presented in the literature believed to achieve competency in other bodily surgical procedures.Copyright © 2019 Author(s) Markose G.; Corsar K.; Graham R.M.
Source British Journal of Oral and Maxillofacial Surgery; Dec 2019; vol. 57 (no. 10) With advances in CT scanning and 3D printing facilities the use of surgical models / stents in maxillofacial surgical planning for implants and oncological work is fairly routine. We present a case where the use of custom cutting guides aided 3D sculpting of a rather overgrown mandible in a young girl with a central giant cell granuloma. En bloc resection can be challenging due to the variable size and location of the tumours and their proximity to surrounding vital tissues. To overcome the challenge of precise resection, computer-aided models were used to assess vital structures, the extent of the affected area and plan surgery. The models were able to accurately identify the course of the mandibular canal. A mirror image of the normal side of the mandible was superimposed on the overgrown mandible and patient-specific guiding templates for resection were fabricated which allowed significant recontouring of the mandible with relative ease. The guiding templates provide significant advantages by guiding surgery, leading to more precise resection of the bone with less blood loss, shorter operation time and avoiding damage to the inferior alveolar nerve. We discuss the pre-operative and operative steps in the surgery and review the results.Copyright © 2019 |
