The “Kissing” Tonsils as Seen During Müller’s Manoeuvre in Obstructive Sleep Apnea Syndrome

December 11th, 2010

This video shows the changes in the airway lumen dimensions of the velopharynx and oropharyngeal areas during Müller’s manouevre which is routinely performed as an office evaluation of obstructive sleep apnea syndrome. Negative pressure being induced by asking the patient to breathe deepy with the nose and mouth close tightly. By doing so, the collapsible segment would be seen approximating particularly at the velopharyngeal isthmus region. Base of tongue collapse, and prominent lingual tonsils will be assessed. In this video, tongue base collapse is not seen, while the most prominent findings were near total closure of the velopharyngeal isthmus contributed by the “kissing” enlarged tonsils. The adenoids, nasal septal deviation, and turbinates hypertrophy need to be evaluated as well as combination surgery is usually needed if they’re present.
