Patient reported outcome measures (PROMs) in bilateral sagittal split osteotomy with osseous genioplasty.

This study evaluates the impact of genioplasty combined with bilateral sagittal split osteotomy (BSSO) on patient-reported outcomes within the UK's National Health Service (NHS). As the first study of its kind in the UK that we know of, it aims to provide evidence to support the continued commissioning of these procedures. A retrospective, multi-site cohort study was conducted using validated patient-reported outcome measures (PROMs) through postoperative telephone consultations. Outcomes assessed included satisfaction with facial appearance, self-confidence, and quality of life before and after surgery. Of 30 eligible patients, 21 completed follow up at a minimum of six months. Results showed high overall satisfaction rates of 90% and significant improvements in psychological wellbeing (40%), quality of life (32%), and social confidence (42%). Additionally, satisfaction with lower jaw appearance and chin aesthetics improved by 60% and 61%, respectively. These findings highlight the significant benefits of genioplasty with BSSO and support its continued commissioning in the NHS.
