Ventricular dysphonia is a poorly understood disorder involving ventricular fold participation during phonation. A population of ventricular dysphonia patients was evaluated using phonatory function studies such as laryngovideostroboscopy, advanced acoustic analysis, and electroglottography to identify shared epidemiologic characteristics and to discuss possible neuromuscular mechanisms and causes. Forty patients with ventricular dysphonia were studied and epidemiologic, acoustic, and histologic data were analyzed. In almost all cases, the authors found abnormalities affecting the glottis caused by a related medical condition. The abnormalities included true vocal cord (TVC) aperiodicity in 100% of the patients, TVC asymmetry in 65%, a laryngeal mass or foreign body (usually Teflon) in 35%, TVC erythema or edema in 32.5%, and TVC bowing in 22.5%. Ventricular dysphonia seems to be primarily a compensatory mechanism for glottic dysfunction. Therapy is based on identifying and correcting the underlying abnormalities. Laryngovideostroboscopy is a particularly important tool in examining chronic dysphonia.
