Abstract
Hyoid expansion is a novel procedure that was developed to widen and stabilize the lateral walls of the hypopharynx in order to improve obstructive sleep apnea. This study was conducted to evaluate the safety, efficacy and feasibility of hyoid expansion. A prospective, non-randomized multicenter pilot study with a follow-up of 6 months was conducted. An implantable device (the Air-Frame system) was used to surgically expand the hyoid bone. Subjective and objective outcome measures were evaluated. The procedure was successfully performed in all patients without technical adverse events. There were three clinical adverse events, and tolerance was good. Although there was a significant improvement in snoring and excessive daytime sleepiness, there was no objective improvement of the apnea-hypopnea index as measured by polysomnography. Hyoid expansion did not provide objective improvement of obstructive outcome measures in patients with obstructive sleep apnea syndrome.
