Definition of Uvulopalatopharyngoplasty

Uvulopalatopharyngoplasty is a surgical procedure aimed at tightening loose tissues and expanding the upper airways. The surgery involves modifying the uvula (uvulo-), soft palate (-palato-), and throat (-pharyngo-). The uvula is a small, soft tissue that hangs from the soft palate at the back of the mouth, often described as U-shaped, tear-shaped, or similar to a grape (its name is derived from the Latin word "uva," meaning grape). The uvula contains a muscle called the musculus uvuae, which helps it stiffen and alter shape, playing a role in closing off the space at the back of the throat. This function is crucial in preventing food from entering the airway during swallowing. Singers often attribute their ability to produce vibrato, a wavering sound, to the uvula. This soft-tissue structure is frequently blamed for snoring and sleep apnea (interruptions in breathing during sleep). Uvulopalatopharyngoplasty is a treatment approach for these issues.
