Anatomy

The uvula is located at the back of the throat, hanging from the middle of the soft palate. It is made up of the musculus uvulae, which is a small muscle that shortens and broadens the uvula. This action helps close the nasopharynx during swallowing, preventing food from entering the nasal cavity.

Function

The uvula plays a role in speech and swallowing. It helps articulate a range of sounds in various languages, particularly those that require a guttural sound. During swallowing, the uvula moves with the soft palate to close off the nasopharynx, directing food down the esophagus.

Clinical significance

The uvula can be involved in several medical conditions. A swollen uvula, known as uvulitis, can cause discomfort and difficulty swallowing. It may result from infections, allergies, or trauma. In some cases, a long uvula can contribute to snoring or sleep apnea.

Surgical procedures

In certain cases, surgical removal of the uvula, known as uvulectomy, may be performed. This procedure is sometimes used to treat snoring or sleep apnea, although it is not commonly recommended due to potential complications.
