Multicentre study of operating time and inpatient stay for orthognathic surgery.
Orthognathic surgery has advanced considerably since its development in the mid-twentieth century, and in most maxillofacial units mandibular and maxillary osteotomies are routine procedures. However, to enable accurate health planning and costing, and to obtain meaningful consent, it is important to have reliable data for duration of operation and inpatient stay. Virtually every aspect of orthognathic surgery has been researched, but we know of no recent studies that have looked specifically at how long the procedures take and how long patients stay in hospital. We retrospectively studied a sample of patients who had had orthognathic operations at six maxillofacial units in the United Kingdom (UK) to assess these measures. We looked at 411 operations which included 139 bilateral sagittal split osteotomies, 53 Le Fort I osteotomies, and 219 bimaxillary osteotomies. The study showed that the mean (SD) operating time for bilateral sagittal split osteotomy is 2h 6min (46min), 1h 54min (45minutes) for Le Fort I osteotomy, and 3h 27min (60min) for bimaxillary osteotomy. The duration of postoperative hospital stay was also measured. Fifty percent of patients spent one night in hospital after bilateral sagittal split osteotomy, whereas 39% and 9% of patients spent two and three nights, respectively. Forty-five percent of patients spent one night in hospital after Le Fort I osteotomy, whereas 34%, 13%, and 2% spent two, three, and four nights, respectively. Forty-one percent of patients spent two nights in hospital after bimaxillary osteotomy, whereas 34%, 21%, and 3% spent one, three, and four nights, respectively. This data provides evidence for national benchmarks.
