These vibrating soft tissues when subjected to negative pressure within the upper airway may lead to collapse of the upper airway. It is known that when inspiratory trans pharyngeal pressure exceeds the pharyngeal dilating muscle action, apneas and hypopneas occur. Collapse of the upper airway is usually multilevel, at the level of the velopharynx, the base of tongue, and the lateral pharyngeal walls. The level of collapse is assessed using the mueller maneuver recorded with fiberoptic flexible nasopharyngoscopy. The mueller maneuver is usually graded on a five-point scale, 0 to 4 ER -
