Diagnosis probable

Presentation

History of right tonsil SCC. Recent completion of radiation therapy. Dysphagia.

Patient Data

Age: 55 years
Gender: Male

Smooth enlargement of the soft palate, epiglottis and aryepiglottic folds can be appreciated on the preliminary spot radiography. 

Bulbous uvula causes incomplete closure and resulted in nasopharyngeal reflux. Similarly, reduced hyoid elevation and diminished epiglottis tilt resulted in laryngeal penetration. The observed acute radiation changes usually last for 2-6 weeks after cessation of therapy.
