dysphonia
Pronunciation: dis-FOH-nee-ah
Abnormal voice production characterized by altered vocal quality, pitch, or loudness.
Full Definition
A voice disorder resulting from dysfunction of the vocal cords or supporting laryngeal structures, commonly occurring after treatment of laryngeal or hypopharyngeal cancers. Dysphonia can manifest as hoarseness, breathiness, roughness, or complete aphonia depending on the underlying pathophysiology. In head and neck oncology, causes include direct tumor effects, surgical trauma to the recurrent laryngeal nerve, radiation-induced tissue changes, or vocal cord paralysis. Assessment typically involves laryngoscopy and voice analysis, with management ranging from voice therapy to surgical intervention.
Usage
Usage note: Do not confuse with dysphagia (swallowing disorder).
