The laser may induce progressive palatal fibrosis, accompanied by medial traction of the posterior tonsillar pillars i.e., scar tissue reduces the airspace in the pharynx leading to velopharyngeal insufficiency. The scar tissue can also make the airway more prone to collapse during sleep. LAUP can be a medically induced cause of sleep apnea.
It can be combined with liposuction to help tighten and smooth over the new contours after removal of excess fat. Resurfacing can be ablative, which vaporizes tissue and creates wounds, or non-ablative which keeps the skin intact. Laser resurfacing is usually done with a 2940 nm Er:YAG laser or a 10,600 nm CO 2 laser.
UPPP involves removal of the tonsils, the posterior surface of the soft palate, and the uvula. The uvula is then folded toward the soft palate and sutured together as demonstrated in the figures. In the US, UPPP is the most commonly performed procedure for obstructive sleep apnea with approximately 33,000 procedures performed per year.
