Ansa Cervicalis and Hypoglossal Nerve Stimulation in OSA
Ansa Cervicalis and Hypoglossal Nerve Stimulation in Obstructive Sleep Apnea
Vanderbilt University Medical Center

INTERVENTIONAL
Conditions
Summary
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.

Interventions
The Grass S88 nerve and muscle stimulator is a widely-used tool in electromyography and nerve conduction studies. During the DISE and second sleep study, fine-wire electrodes will be placed into the hypoglossal nerve or genioglossus muscle. Two more electrodes are placed transcutaneously, proximate to the bilateral branches of the cervicalis innervating the sternothyroid muscle in the anterior neck.
