Hyoid Suspension to the Mandible for the Treatment of Obstructive Sleep Apnea

Status unconfirmed

Conditions studied: Obstructive Sleep Apnea

In brief

Hyo-mandibular suspension has been previously studied as a treatment for obstructive sleep apnea (OSA) and has shown to be highly effective. This is a prospective, multi-center, registry during which 30 subjects with OSA will be considered for hyo-mandubular suspension treatment. After obtaining informed consent and meeting all inclusions and exclusion criteria, subjects will be treated using the Encore System. Subject follow-up with the physician or nurse will occur at one (1) week, one (1) month, three (3) months, and twelve (12) months. This study will assess the effectiveness of hyoid suspension in reducing the apnea-hypopnea index (AHI), and improving the Epworth Sleepiness Scale (ESS), snoring (VAS) and functional outcome (FOSQ) for the treatment of obstructive sleep apnea (OSA). In addition, the study will evaluate the effect that the change in hyoid position has on the airway anatomy.
