A diagnosis of obstructive sleep apnea as determined by polysomnogram with an apnea-hypopnea index of ≥ 5.0/hr.
Adult patient (≥18 years old)
Must not have
Cardiopulmonary or other medical conditions precluding safe propofol sedation as determined by pre-operative anesthesia evaluation
History of palatal or pharyngeal airway surgery including tonsillectomy as determined by clinical history and exam
Timeline
Screening 3 weeks
Treatment Varies
Follow Up collected during operative procedure, taking about 15 minutes.
Awards & highlights
No Placebo-Only Group

Summary

This trial will study the effects of two different types of muscle stimulation on the upper airway during sleep.

Who is the study for?
This trial is for adults over 18 with obstructive sleep apnea, confirmed by a sleep study, who can't use CPAP machines comfortably. They must be scheduled for DISE to check their throat structure and agree to research consent. Excluded are those with certain neurological conditions, language barriers, egg allergies, pregnancy, unsafe conditions for sedation or past head/neck surgery or radiation.
What is being tested?
The study tests the effects of stimulating two muscles in the throat using a Grass S88 Muscle Stimulator during drug-induced sleep endoscopy (DISE). It aims to understand how this stimulation affects airway collapse patterns related to obstructive sleep apnea.
What are the potential side effects?
While specific side effects aren't listed here, muscle stimulators may cause discomfort at the stimulation site, twitching muscles during application and potential skin irritation from electrode placement.
