Use of online educational resources before and during the COVID-19 era in oral and maxillofacial surgery.

Restrictions to traditional face-to-face meetings were mandated by many government authorities during the COVID-19 pandemic, impacting the delivery of educational training sessions for maxillofacial surgery trainees in the traditional group manner. An online survey was designed to review what effect the pandemic had on the use and uptake of online educational sources amongst a representative cohort of maxillofacial surgery trainees in higher specialist training. Their attitudes and satisfaction with online resources were considered. The use of live sources such as webinars and pre-recorded materials (e.g. YouTube videos) was investigated. Engagement with online sources was considered prior to, and then during the pandemic. Alterations in the behaviour of trainees were demonstrated, with increasing online resource use seen once the COVID-19 pandemic took hold. Online pre-recorded resource use increased by 26% during the pandemic, with the median number of hours watched per month increasing from 1-5 h to 5-10 h (p < 0.001). Engagement with live online sources (webinars) increased by 52% and median time watched increased from 15 h per month to 10-20 h per month (p < 0.001). Trainees expressed satisfaction with the quality and flexibility of the resources. There was a firmly positive response to live webinars with regard to teaching quality, audio and video quality, ease of access and relevance to training needs. Pre-recorded and live online resources may prove a useful alternative or adjunct to face-to-face teaching when regulations limit or restrict social interactions.

A prospective cohort study evaluating subjective and objective neurosensory changes following LeFort I osteotomy.

INTRODUCTION: This study aimed to investigate the incidence and recovery of neurosensory deficit (NSD) after LeFort I osteotomy over 12 months and identify any association between age, gender, and extent of surgical movement on recovery. Furthermore, the study explored the relationship between objective and subjective outcome measures. METHODS: A prospective cohort study consisting of 31 patients. Subjects were assessed at baseline, 1 week (T1), 1 month, 3 months, 6 months, and 12 months (T5) after LeFort I osteotomy. Objective assessment measures included pinprick (PP), static light touch (SLT), static 2-point discrimination (STPD), and electric pulp testing (EPT). Subjective reporting was undertaken using a visual analog scale. Patients rated the impact of NSD on intraoral and extraoral sites at the same time points as for objective measures. RESULTS: Twenty-eight patients (16 females and 12 males) with a mean age of 24.5 years (standard deviation, 7.4) completed the study. There was a notable reduction in NSD from T1 (85.7%) to T5 (17.9%). No significant differences were found with respect to the influence of gender; PP (P = 0.06), SLT (P = 0.10), STPD (P = 0.65) and EPT (P = 0.19) or extent of surgical movement; PP (P = 0.50), SLT (P = 0.72), STPD (P = 0.06) and EPT (P = 0.74) on NSD. Age is a significant factor for intraoral NSD in the immediate postoperative period; PP (P < 0.0001) and SLT (P < 0.0001). Subjectively, patients reported a high degree of concern associated with NSD immediately after surgery with a gradual reduction from T1 to T5. There is a significant difference in subjective reporting between those with intraoral NSD than those with no intraoral NSD at 12 months (P = 0.031). CONCLUSIONS: NSD is high after LeFort I surgery, particularly intraorally in the palate. At 12 months, the incidence of NSD is 17.9%. Recovery of NSD to a nonsignificant value from baseline takes up to 3 months for extraoral sites and between 3 and 6 months for intraoral soft tissues. The maxillary dentition continues to recover from NSD up to 12 months postsurgery. Age, gender, and extent of the surgical movement do not influence the extent of NSD at 12 months. Increasing age is associated with increased NSD at intraoral sites immediately after surgery. Intraoral NSD is more of a concern to patients than extraoral NSD. Patients' concerns associated with NSD reduced over time, demonstrating a degree of adaptation in the longer term.
