An Innovative Concept to Replace Drug-Induced Sleep Endoscopy (DISE): A Futuristic Approach to Assessment of Upper Airway Collapse in Obstructive Sleep Apnea Syndrome (OSAS) Patients During Normal Physiological Sleep at Home.

The collapsibility and dynamic phenomenon of the upper airway in obstructive sleep apnea syndrome (OSAS) patients during sleep is a complex mechanism. Its assessment prior to definitive surgery by drug-induced sleep endoscopy may mimic a snap shot of airway collapse during natural sleep. However, it still presents a shortcoming even after three decades of research and evolution in its technique. The hypothetical concept is to perform an overnight objective assessment of the upper airway collapsibility by the acoustic reflection technique in OSAS patients to decide the appropriate management plan.
