Retrospective analysis of postoperative interventions in mandibular fractures: a shift towards outpatient day surgery care

The management of fractured mandibles typically involves admission and operation at the time of presentation. While this should involve only a short stay in hospital these patients are surgically stable, and so priority is often given to more urgent cases. We retrospectively evaluated the postoperative medical requirements of patients who were operated on at Fiona Stanley Hospital, Perth, Western Australia between 1 January 2015 and 31 December 2016. Patients were excluded if they had had multiple facial fractures, multiple injuries, had fractures that were comminuted or in edentulous mandibles, and those who had been in hospital for preoperative medical investigations and care. We also excluded fractures in children aged 16 years and under. The results showed that of a total of 173 patients, 12 had had medical consultations during their hospital stay, and only four had required intervention. The mean (range) preoperative time was 37 (1 - 46) hours and that from operation to discharge 21.5 (2 - 93) hours. While traditional management involves emergency admission and open reduction and internal fixation as soon as possible, delays of up to five days were not associated with appreciably worse outcomes. This, together with the negligible requirements for medical management perioperatively, provides a strong argument for a selected group to be treated as outpatients.
