MÃÆ'üller Maneuver is a procedure used in medicine to diagnose sleep apnea, some types of tinnitus, and other medical problems.

Procedures
After forced expiration, the inspiration effort is done with the mouth and nose closed, where the negative pressure on the chest and lungs is made very subatmosfir; the opposite of the Valsalva maneuver.
This technique is designed to search for disconnected air ducts such as trachea and upper air ducts. In this maneuver, the patient attempts to inhale with his mouth closed and his nostrils stuck, which leads to the collapse of the airways. Introducing a flexible fiberoptic scope into the hypopharynx to get a view, the examiner can witness the collapse and identify the weak parts of the airway. MÃÆ'üller maneuver is used to help determine the cause of sleep apnea. A positive test result means that the upper airway obstruction site may be below the soft palate level, and the patient may not benefit from uvulopalatopharyngoplasty alone. This maneuver is helpful in performing MRI for sleep apnea, when sedation to the patient can be avoided.
There is some evidence that obstruction sites with MÃÆ'üller maneuvers do not represent the site of obstruction during normal sleep. Other factors such as body position during maneuvering may affect this.
MÃÆ'üller maneuvers can also be used to terminate supraventricular tachycardia in an acute primary care setting.
