What does the UPPP procedure involve?

Uvulopalatopharyngoplasty (UPPP) is a surgical procedure that removes excess soft tissue from the pharynx, including the uvula, soft palate, and sometimes the tonsils, to widen the airway and reduce retropalatal collapse. Performed under general anesthesia, it typically takes 1–2 hours and aims to alleviate obstructive sleep apnea by preventing the soft palate from blocking the throat during sleep. The surgery is targeted at the retropalatal region, where tissue redundancy is most common.
