ABSTRACT |
Background and Objectives : Functional dysphonia is a voice disturbance in the absence of structural or neurologic laryngeal pathology characterized by voluntary misuse of laryngeal muscles. The present report reviews clinical characteristics of 25 patients with functional dysphonia. Materials and Method : We analyzed medical records, perceptual and acoustic analysis of voice samples, aerodynamic studies and laryngoscopy. Results : There was no sex or age predilection. Eighty four percent of patients presented sudden onset of symptoms and 76% had specific events at the onset. Most patients showed breathy or strained voice and various degree of vocal fold insufficiency with supraglottic compensatory contractions. Acoustic analysis revealed non-diagnostic, but mean flow rate was lower than normal in all cases. All patients responded to voice therapy except for 4 patients who were tort to follow up. Mean number of voice therapy sessions required to get responses is 1.9 sessions. Conclusion : We concluded that patients with functional dysphonia responded very well to short-term voice therapy and should be included in differential diagnosis in patients with dysphonia cannot be explained by structural or neurologic etiology. |
