Genioglossal advancement is a surgical procedure for obstructive sleep apnea (OSA) that has lost favor as a primary treatment strategy. The authors describe utilization of a modified genioglossal advancement (MGA), combining a geniotubercle advancement via sliding genioplasty and a glossopexy.


A retrospective review was performed. Preoperative and postoperative apnea–hypopnea indices (AHIs) were compared to determine OSA treatment success.


Five patients underwent MGA. Three subjects had preoperative and postoperative AHI scores which improved from 61, 28, and 19 (mean = 36) to 4.5, 2, and 6.3 (mean = 4.3), respectively. Two subjects had incomplete data for comparison. All subjects had an acceptable esthetic outcome.


In properly selected subjects, MGA can alleviate OSA and provide improved esthetic outcomes.
