초록

Spasmodic dysphonia (SD) is a chronic, focal, speech-induced, action-specific dystonia, resulting strained voice. Muscle tension dysphonia (MTD) may also result in a strangled, strained voice quality, usually as a result of compensation for underlying laryngeal disease such as glottal insufficiency. Patients with SD and MTD were suffered from the severely limiting people's communication, especially via telephone and in noisy backgrounds. SD is usually of the adductor type characterized by glottic contractions causing tightness and voice breaks, which is difficult to distinguish from MTD. In this review article, we present the characteritics and management of SD and MTD.
