Muscle Stimulation During DISE

Enrolling By InvitationNA

Sponsor: Vanderbilt University Medical Center

Conditions: Obstructive Sleep Apnea

Interventions: Grass S88 Muscle Stimulator

Countries: United States

Drug-induced sleep endoscopy (DISE) is a widely used tool for assessing collapse patterns of the upper airway anatomy during sleep. Hypoglossal nerve stimulation therapy for obstructive sleep apnea suffers from variable response at the level of the soft palate. We propose a study examining the physiologic effect of palatoglossus and genioglossus muscle stimulation during DISE.
