Müller's maneuver is a procedure used in medicine to diagnose some types of tinnitus,[1] and other medical problems.
In this maneuver, the patient attempts to inhale with their mouth closed and their nostrils plugged, which leads to a collapse of the airway.
Introducing a flexible fiberoptic scope into the hypopharynx to obtain a view, the examiner may witness the collapse and identify weakened sections of the airway.
A positive test result means the site of upper airway obstruction is likely below the level of the soft palate, and the patient will probably not benefit from a uvulopalatopharyngoplasty alone.
Müller's maneuver can also be used to terminate supraventricular tachycardia in an acute primary care setting.
