This retrospective evaluation of surgical outcomes for hyomandibular suspension when performed with uvulopalatopharyngoplasty (UPPP) for the treatment of obstructive sleep apnea (OSA). Thirty-nine patients with moderate-to-severe OSA were treated with hyoid myotomy and suspension and uvulopalatopharyngoplasty. Patients underwent hyoid advancement and suspension to the mandible (Encore System) with either staged or concurrent UPPP. The primary outcome was a successful surgical result, defined as an apnea hypopnea index (AHI) lower than 20, and a 50% or greater decline in AHI on postoperative polysomnography. Successful surgical results were achieved in 30 (76.9%) out of 39 patients. The mean preoperative AHI improved 69.2% from 49.9 ± 25.6 to 15.4 ± 14.9 (P <.001) postoperatively. All patients reported clinical improvement of symptoms. There were 4 wound complications and one infection requiring removal of hardware. For patients with multilevel obstructive sleep apnea, hyoid advancement and suspension to the mandible appears efficacious when performed in conjunction with uvulopalatopharyngoplasty.
