STUDY OBJECTIVES: Craniofacial malformations with micrognathia cause high grades of obstructive sleep apnea (OSA) measured by polysomnography (PSG). Mandibular distraction osteogenesis is a novel procedure for upper airway obstruction relief. Our primary objective was to describe the utilization of PSGs to improve obstruction in patients undergoing mandibular distraction.
METHODS: This is a retrospective study. Patients with micrognathia and severe upper airway obstruction, presenting with severe OSA diagnosed by PSG, were included from a single tertiary care center between 2015 and 2019. PSGs were done (1) prior to surgery, (2) once the cosmetic goal was achieved (Post-Op 1), and (3) if residual moderate-to-severe OSA was seen, every 2 nights until mild or no OSA was achieved (Post-Op 2).
RESULTS: Thirteen patients were included. The median age at surgery was 1.1 months (10 days-3 months). All 13 patients had baseline severe OSA, with a median obstructive apnea-hypopnea index of 33 events/h and a median O2 nadir of 73%. Post-Op 1 PSG was done at a median of 6 days after surgery. Median first postoperative obstructive apnea-hypopnea index in all 13 patients was 6.8 events/h, with a median O2 nadir of 87%. A median additional distraction of 3 mm was needed beyond the traditionally recommended advancement. Long-term follow-up studies at or after 1 year were done in 5 patients, all showing persistent nonsevere OSA.
CONCLUSIONS: This is the first case series utilizing PSGs as a guide for mandibular distraction osteogenesis in patients with micrognathia showing the need for jaw overcorrection to achieve resolution of OSA.
