过去认为痉挛性发声困难是精神躯体性疾病。治疗效果很不满意。1976年作者报告单侧喉返神经切断,术后配合声音治疗,92%获得减轻痉挛的满意效果。本文报告314例确诊为痉挛性发声困难的病例中,306例作了喉返神经切断术。该手术只对真正的痉挛性发声困难有效。如同时合并声音震颤一类疾患,后者可抵销手术效果,因此术前对这种病人应予认识。耳语和间歇性耳语性发声困难不能用喉返神经切断术治疗。本文采用自我主观评价和客观声音评价进行疗效分析。在自我评价中,每人在术后1～6年填写一询问表。结果:在噪声中,术后各年大部分病人都有语言交往困难,尤以术后一年发病率最高,术后第三年较低。但与术前相比均有好转。
In the past that spasmodic dysphonia is a mental physical disease. The treatment effect is not satisfied. In 1976, the authors reported unilateral recurrent laryngeal nerve transection, postoperative with sound therapy, and 92% achieved satisfactory results in reducing spasticity. Of the 314 reported cases of spasmodic dysphonia, 306 reported recurrent laryngeal neurotomy. The surgery is only effective for true spasmodic vocal dysfunctions. Such as the simultaneous merger of tremor of a class of diseases, the latter can offset the effect of surgery, preoperative patients should be aware of this. Whisper and intermittent whisper dysphonia can not be treated with recurrent laryngeal nerve. In this paper, self-subjective evaluation and objective sound evaluation of the efficacy of analysis. In self-evaluation, each person in the postoperative 1 to 6 years to fill in a questionnaire. Results: In the noise, most of the patients had difficulties in language communication after the operation, especially in the first year after operation and the third year after operation. But compared with preoperative have improved.
