Is it Necessary to Perform Drug-induced Sleep Endoscopy in Severe Obstructive Sleep Apnea?

Abstract

ABSTRACT Aim To study the role of drug-induced sleep endoscopy (DISE) and Muller's maneuver in diagnosing obstructive sleep apnea (OSA). Materials and methods This was a comparative study done on 30 patients above the age of 18 years with OSA. All the study subjects underwent Muller's maneuver and DISE. In both endoscopic procedures, the degree and type of airway collapse noted at the retropalatal and retrolingual levels. Result Our study revealed similar findings with regard to type and degree of airway collapse at the retropalatal and retrolingual levels with both Muller's maneuver and DISE. Conclusion The type and degree of upper airway collapse at the retropalatal and retrolingual levels in DISE were similar to that of Muller's maneuver in severe OSA. Hence, DISE is not necessarily a diagnostic tool in case of severe OSA. How to cite this article Patla SDK, Koikkara R.
