Thyroplasty type III provides an effective mean of shortening the vocal fold. It is used primarily fer lowering vocal pitch. The indications for this surgery are the male patients with too high a vocal pitch of long duration which has proven resistant to voice therapy and a type of dysphonia characterized by high pitch and a breathy voice, in which the laryngeal findings include a very narrow glottal chink and a small amplitude of vibration, suggesting a stiff vocal cord. In this study, we have experienced two cases of high pitched voice, one is mutational falsetto and other is high pitched, breathy voice with stiff vocal fold. The results were satisfactorily successful with type III thyroplasty. So we report the cases of type III thyroplasty in patients of dysphonia with high pitched voice.
