简要总结
Drug-induced sleep endoscopy (DISE) is the most used technique for identifying the obstruction site associated with obstructive sleep apnea (OSA). This is due to the fact that it allows many patients to be examined in a daytime setting. This procedure uses sedative drugs to mimic natural sleep. However, associations with the site of upper airway (UA) collapse during natural sleep remain unclear.
The aim of this explorative study is to identify UA collapse in patients with OSA using endoscopic techniques as well as flow shape characteristics and sound analyses during natural and drug-induced sleep. Furthermore, we want to optimize the measurement set-up of natural sleep endoscopy (NSE).
详细描述
Patients with moderate to severe OSA requiring DISE will be recruited for this prospective study at the outpatient clinic. Patients will undergo a NSE at the sleep lab at night, and a DISE at the operating theatre within three months. Both the NSE and DISE set-up will include gold-standard flow measurements, acoustic analysis and esophageal pressure measurements.

盲法说明
NSE and DISE will be performed by two separate researchers, blinding the ENT surgeon who performs the NSE or DISE for the outcome of the other procedure. This is a blinded study and the researchers will have no knowledge of the patient's characteristics / demographic variables and their history.
