  • Obstructive Sleep Apnea

Purpose:

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.


Study summary:

This is a single-arm study involving the use of a diagnostic device (muscle stimulator) that is not currently utilized in any clinical decision-making processes for OSA patients. All patients scheduled for DISE as part of their regular clinical care will be screened for enrollment via the previously described inclusion and exclusion criteria. The study is not blinded. No diagnostic information collected from muscle stimulation will be used in clinical decision-making processes.


Criteria:

Inclusion Criteria: 1. Adult patient (≥18 years old) 2. A diagnosis of obstructive sleep apnea as determined by polysomnogram with an apnea-hypopnea index of ≥ 5.0/hr. 3. Intolerant of CPAP therapy due to physical or psychosocial limitations as determined by clinical history 4. Scheduled to undergo DISE as part of routine clinical assessment for further evaluation of pharyngeal anatomy Exclusion Criteria: 1. Unable to consent for research due to a pre-existing neurologic condition as determined by PI 2. Unable to consent for research due to language barriers 3. A history of egg allergy as determined by history or self-reports 4. Currently pregnant as determined by patient report or pre-operative anesthesia evaluation 5. Cardiopulmonary or other medical conditions precluding safe propofol sedation as determined by pre-operative anesthesia evaluation 6. History of palatal or pharyngeal airway surgery including tonsillectomy as determined by clinical history and exam 7. History of radiation treatment to the head or neck as determined by history and/or physical exam
