Abstract

OBJECTIVES: This study explored the correlation between clinical explorations, including modified Mallampati score and Müller's maneuver, with drug-induced sleep endoscopy (DISE) findings regarding retrolingual obstruction. METHODS: One hundred forty-two obstructive sleep apnea patients were enrolled in this prospective study. All of the patients received clinical explorations including modified Mallampati scoring and Müller's maneuver in the clinic. Drug-induced sleep endoscopy was further evaluated in the operating room. RESULTS: A significant relationship was noted between modified Mallampati score and retrolingual obstruction during DISE. In contrast, no significant relationship was noted between Müller's maneuver and DISE findings regarding retrolingual obstruction. CONCLUSIONS: A significant discrepancy existed between retrolingual airway collapse evaluated by modified Mallampati score and Müller's maneuver. Modified Mallampati score is more correlated with DISE regarding retrolingual obstruction compared to Müller's maneuver. It should therefore be used as an initial evaluation of retrolingual obstruction when DISE is unavailable.
