    Abstract The coronavirus disease 2019 caused by the Severe Acute Respiratory Syndrome Coronavirus-2 has resulted in many confirmed cases around the world. Sars-CoV-2 remains viable and infectious in aerosols dispersed in air and is viable on surfaces up to several days. Symptomatic patients are the main reservoir for transmission. Evidence suggests that asymptomatic patients and patients during their incubation period can shed and transmit Sars-CoV-2. The infective potential can be reduced through the use of personal protective equipment. Healthcare professionals especially the oral maxillofacial surgeons are at increased risk of being infected by the virus. Oral maxillofacial injuries typically involve vital structures in the upper aerodigestive tract and are emergent. Facial trauma surgery cannot be delayed or deferred in a pandemic. This review focuses on precautions surgeons should adopt while managing facial trauma patients in the emergency department and whilst performing emergency surgeries on these patients during the current COVID-19 pandemic. Strict and effective infection control protocols for facial trauma management are needed to minimise this risk of transmission. This review was part of the lecture given by Professor Melvyn Yeoh at the 14th Asian congress on Oral and Maxillofacial Surgery recently held virtually in Singapore due to the pandemic.

    Abstract There has been a lot of focus on osteonecrosis of the jaws associated with the usage of bisphosphonates both in dental and medical literature in recent years. However, the exact pathogenesis of bisphosphonate-related osteonecrosis of the jaws remains unclear. Against the background of emerging evidence of an evolving condition, it is not surprising that there is a lack of robust evidence-based recommendations on dental treatment of patients on bisphosphonates. This paper seeks to provide a rational approach to the dental management of patients on bisphosphonates based on current literature.

    Abstract Introduction: Failure of airway management remains a significant source of morbidity and mortality. Advanced airway management has been addressed effectively by simulation-based training. However, simulation of difficult airways in manikins is limited by the pre-set conditions provided by the manufacturer. Life-like conditions in the form of the softness of the tissue and true anatomy as seen in cadaver models are needed to create simulated models with a closer resemblance to real patients. The goal of this study was to determine the feasibility of simulating difficult airway from submandibular abscess in cadaver models by surgical modification of the cadaver heads for use in enhanced experiential learning of the management of difficult airways.
    Methods: The cadaver heads were modified surgically to simulate a submandibular abscess. The models were used in an airway course where participants provided feedback on the realistic nature of the model and its benefits for difficult airway training. The ease of tracheal intubation of the models with the assistance of video laryngoscopy was assessed.
    Results: The modified cadavers were acceptable in simulating difficult airway as demonstrated by the feedback from the participants. All participants (100% [95% confidence interval = 89.1%-100%]) found the models to be realistic and beneficial for difficult airway training. A good proportion (56.3%) felt that the intubation technique was made easier with the video laryngoscopy.
    Conclusions: Cadavers can be modified to simulate pathologies associated with difficult airways. These models can be used to enhance experiential learning and the management of difficult airways.

    Abstract Purpose: Education in airway management is a fundamental component of anesthesiology training programs. There has been a shift towards the use of simulation models of higher fidelity for education in airway management. The goal of this study was to create a novel cadaveric model of a simulated parapharyngeal abscess with features of a difficult airway such as distorted anatomy and narrow airway passages presenting as stridor. The model was further assessed for its suitability for enhanced experiential learning in the management of difficult airways.
    Methods: Cadaver heads were modified surgically to simulate parapharyngeal abscess. Airtight torso of the cadaver was connected to an Oxylog ventilator to simulate respiratory movements-the opening and closing of air channels with breaths in a patient with parapharyngeal abscess. Advanced airway workshop facilitators conducted directed one-to-one learning, and provided feedback to participants. A paper-based feedback was obtained from 72 participants on their confidence level, and the realism, attractiveness, beneficial, and difficulty levels of the simulated cadaveric models.
    Results: The modified cadavers were reliable in simulating difficult airways. The majority of participants (91%) reported an increase in confidence level for management of the difficult airway after the experience with the modified cadavers and found the models realistic (93%), attractive (92%), beneficial (93%), and difficult (85%).
    Conclusions: Surgical modifications of cadavers to simulate difficult airways such as parapharyngeal abscess with edema and stridor can be incorporated into advanced airway management courses to enhance experiential learning in airway management by awake fibreoptic intubation, and promote patient safety.

    Abstract Purpose: This prospective observational cohort study sought to determine the prevalence of inferior alveolar nerve (IAN) injury after mandibular fractures before and after treatment and to elucidate factors associated with the incidence of post-treatment IAN injury and time to normalization of sensation.
    Materials and methods: Consenting patients with mandibular fractures (excluding dentoalveolar, pathologic, previous fractures, or mandibular surgery) were prospectively evaluated for subjective neurosensory disturbance (NSD) and underwent neurosensory testing before treatment and then 1 week, 1.5, 3, 6, and 12 months after treatment.
    Results: Eighty patients (men, 83.8%; mean age, 30.0 yr; standard deviation, 12.6 yr) with 123 mandibular sides (43 bilateral) were studied. Injury etiology included assault (33.8%), falls (31.3%), motor vehicle accidents (25.0%), and sports injuries (6.3%). Half the fractures (49.6%) involved the IAN-bearing posterior mandible; all condylar fractures (13.0%) had no NSD. Treatment included open reduction and internal fixation (ORIF; 74.8%), closed reduction and fixation (22.0%), or no treatment (3.3%). Overall prevalence of IAN injury was 33.7% (95% confidence interval [CI], 24.8-42.6) before treatment and 53.8% (95% CI, 46.0-61.6) after treatment. In the IAN-bearing mandible, the prevalence was 56.2% (95% CI, 43.2-69.2) before treatment and 72.9% (95% CI, 63.0-82.7) after treatment. In contrast, this prevalence in the non-IAN-bearing mandible was 12.6% (95% CI, 4.1-21.1) before treatment and 31.6% (95% CI, 20.0-43.3) after treatment. Factors associated with the development of post-treatment IAN injury included fracture site and gap distance (a 1-mm increase was associated with a 27% increase in odds of post-treatment sensory alteration). Time to normalization after treatment was associated with type of treatment (ORIF inhibited normalization) and fracture site (IAN-bearing sites took longer to normalize).
    Conclusion: IAN injury was 4 times more likely in IAN-bearing posterior mandibular fractures (56.2%) than in non-IAN-bearing anterior mandibular fractures (12.6%). After treatment, IAN injury prevalence (in 12 months) was higher (72.9% in posterior mandible, 31.6% in anterior mandible).
