Orthognathic surgery in Covid-19 times, is it safe?

COVID-19 has impacted the provision of orthognathic surgery globally. Uncertainty around its effects and transmission in aerosol generating procedures (AGP's) has led to disagreement within maxillofacial surgeons into the safety of orthognathic surgery during the pandemic. We present a local case series of orthognathic surgery undertaken during the COVID-19 pandemic. To our knowledge no such similar study has been reported worldwide. Data was collected from the 1st June to 30th November 2020 for all patients undergoing orthognathic surgery by a single consultant. All procedures and inpatient stays were performed 'off site' at the local Spire Healthcare Group plc© facility. A strict preoperative two-week self-isolation period and negative COVID-19 testing was mandatory. All procedures were classified as AGP's and personal protective equipment (PPE) was worn in line with local guidelines. The primary outcome was 30-day COVID-19 infection among patients, with day 0 the date of surgery. Secondary outcome measures included duration of stay, return to theatre and complications. A total of 59 patients were identified. 42/59 had bimaxillary procedures and 17/59 single jaw. 9/17 had maxillary and 8/17 had mandibular procedures. A total of 3/59 had simultaneous genioplasty. Median duration of stay was one night (range 1-3). Immediate and late complications were seen in 3% (2/59) and 3% (2/59) respectively. Only 1% (1/59) returned to theatre. Zero patients tested positive in the 30-day postoperative period. No staff members tested positive for the duration of the study. Adopting strict safety protocols, orthognathic surgery can be safely delivered during the pandemic without detriment to the patient or staff.
