Uvula of palate

The uvula is a conical, midline projection from the posterior edge of the soft palate. It plays an important role in speech, swallowing, and airway protection, and is part of the palatopharyngeal complex. Understanding its anatomy, function, and imaging characteristics is essential for radiologists, ENT specialists, and surgeons, particularly when evaluating congenital anomalies, trauma, or soft palate masses.

Synonyms

  • Palatine uvula

  • Soft palate uvula

  • Uvula palatina

  • Posterior soft palate tip

Function

  • Assists in closing the nasopharynx during swallowing to prevent nasal regurgitation

  • Plays a role in speech resonance and articulation

  • Contributes to the gag reflex

  • Helps in directing food and liquids during swallowing

MRI Appearance

T1-weighted images:

  • The uvula appears as a soft tissue structure with intermediate signal intensity

  • Surrounded by the hyperintense fat of the oropharyngeal space, enhancing its borders

  • Pathologies such as tumors or edema may appear hypo- to isointense and enhance after contrast

T2-weighted images:

  • The uvula shows intermediate signal, while surrounding fluid or edema is hyperintense, making inflammatory or neoplastic changes conspicuous

  • Helps detect cystic lesions, mucosal edema, or soft palate tumors

STIR (Short Tau Inversion Recovery):

  • Suppresses fat signal, highlighting pathological changes

  • Normal uvula is low-to-intermediate signal, whereas edema, inflammation, or tumors appear hyperintense, aiding detection of subtle lesions

CT Appearance

  • On CT, the uvula appears as a soft tissue density structure at the posterior margin of the soft palate

  • Surrounded by air within the oropharynx, which appears hypodense (black), providing natural contrast

  • Useful for assessing masses, mucosal thickening, trauma, or cysts
