Ansa Cervicalis and Hypoglossal Nerve Stimulation in OSA (NCT05501236)

Ansa Cervicalis and Hypoglossal Nerve Stimulation in Obstructive Sleep Apnea

๐ŸŸข Recruiting Observational / Diagnostic โš™๏ธ Medical Device Protocol Sponsor: Vanderbilt University Medical Center

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

Polysomnography (PSG) and drug-induced sleep endoscopy (DISE) are widely used diagnostic studies for assessing obstructive sleep apnea (OSA) severity and collapse patterns of the upper airway anatomy during sleep. Hypoglossal nerve stimulation (HNS) therapy for obstructive sleep apnea suffers from variable response at the level of the soft palate. The Investigators propose a study examining the physiologic effect of ansa cervicalis stimulation (ACS) alone and in combination with HNS during PSG and DISE.
