ABSTRACT

The causes of dysphonia can be classified into two groups, organic and functional. Functional dysphonia includes spasmodic dysphonia, muscle tension dysphonia, mutational dysphonia and conversion dysphonia, etc. The findings of laryngoscopy in these dysphonia are almost normal. Organic dysphonia is caused by anatomical problems in the larynx, especially on the vocal fold. Benign diseases of the vocal folds are common and mainly presented as voice disorders such as hoarseness, harshness, weakness, or even loss of voice. Benign neoplasm of the larynx are very rare condition except papilloma. The most common symptoms are voice change. However, they can be presented as wheezing, dyspnea, discomfort in the throat, or cervical mass depending on the size and location of the tumor. Detailed history taking and thorough laryngeal endoscopic examination are necessary for the appropriate diagnosis and treatment.
