痉挛性发声困难首先由Traube(1871)报告,其发生可能是基于精神性,尤其是转化反应(Traube等)或系神经性起因(Robe et al,1960)。本病有内收和外展两型,以内收型多见。内收型者是以发声时突然声门紧闭产生痉挛而用力的声嘶为特征的嗓音病征,可在笑、唱、叫、怒时,在正常语音中突现紧张、沉闷、痉挛的嘶哑声,并常伴有愁眉苦脸、颈肌抽搐、联动瞬目、胸部扩张和腹壁内收等运动,可见到声带、室带和咽肌等痉挛和过度内收。须鉴别有无转化、抑郁、焦虑反应等精神病及假性球麻痹、肌张力不足、痉挛性斜颈、特发性语音震颤等神经病,若无此类情况,可称为特发性发声困难。本病曾用精神疗法、言语疗法、生物反馈、催眠术、针灸、刺激、药物等治疗,但收效甚微或无效。Dedo(1976)首倡用一侧喉返神经切断术治 Spasmodic vocal dysphonia was first reported by Traube (1871), and its occurrence may have been based on psychicity, particularly the conversion reaction (Traube et al.) Or a neurogenic cause (Robe et al., 1960). The disease has adduction and outreach two types, less than the type of admission. The adducting type is characterized by voice hoarseness characterized by vocalization of the closed glottic spasm while voice, can laugh, sing, call, anger, in normal voice sudden tension, dull, spasmodic hoarse voice , And often accompanied by frown, neck muscle twitching, blink of an eye movement, chest expansion and abdominal adduction and other movements, we can see vocal cord, ventricular band and pharyngeal muscle spasms and excessive adduction. To identify whether the conversion, depression, anxiety and other mental illness and pseudobulbar palsy, muscle tension, spasmodic torticollis, idiopathic speech tremor and other neurological diseases, in the absence of such cases, can be called idiopathic dysphonia. The disease has used psychotherapy, speech therapy, biofeedback, hypnosis, acupuncture, stimulation, drugs and other treatment, but with little or no effect. Dedo (1976) advocated the use of one side of the recurrent laryngectomy
