The Magnetic Resonance Imaging in Obstructive Sleep Apnea trial is an observational cohort study recruiting adults with obstructive sleep apnea undergoing surgery.
Thewill compare drug-induced sleep endoscopy and upper airway MRI in order to determine which is the better predictor of success in patients who cannot tolerate nonsurgical solutions. Upper airway MRI is a more complete evaluation during wakefulness and is cheaper than drug-induced sleep endoscopy, but no studies have thus far utilized MRI as a surgical evaluation tool.
Patients will be included if they are at least 21 years old, have moderate to severe obstructive sleep apnea, and have a body mass index less than 40 kg/m2. Exclusion criteria include prior surgery for obstructive sleep apnea; known neurologic, cardiac, pulmonary, renal, or hepatic disorders; psychiatric problems except for treated depression or mild anxiety; a coexisting sleep disorder; or another contraindication to drug-induced sleep endoscopy or MRI, such as propofol allergy.
The primary outcome measure is surgical results after 6 months, which will be measured using sleep studies. Secondary outcomes include sleep-related quality of life after 6 months and daytime sleepiness after 6 months.
The estimated primary completion date is June 2020, and the estimated study completion date is July 2020. About 40 patients are expected to be recruited.
