In the period 1960 to 1970, a total of 213 patients underwent subtotal thyroidectomy for benign cervical toxic goitre. Postoperatively, immobile vocal cord indicating paralysis of the recurrent nerve was found in 17 patients. In 8 patients, immobility of the vocal cord was permanent. Seven of the 17 patients received voice training which was initiated within 3 weeks after operation. After a period of 5-10 years, on an average 8 years, the 17 patients had a clinical and a comprehensive objective examination of the voice function comprising stroboscopy, electroglottography, phono-oscillometry, voice range, phonation time, peak-flow and pitch. Only a few complaints were ciliated whereas the objective examination of the voice function revealed abnormal findings in all but one patient. The findings were less abnormal in patients who had received early voice training. It is concluded that despite abnormal objective findings, all 17 patients found their voice function satisfactory. Moreover, early voice training seemed to offer a fair chance of minimizing late voice problems, whether the paralysis was permanent or transitory.
在1960年至1970年期间，共有213例患者因良性颈部毒性甲状腺肿接受了甲状腺次全切除术。术后，17例患者出现声带固定，提示喉返神经麻痹。其中8例患者声带固定为永久性。17例患者中有7例在术后3周内开始接受嗓音训练。经过5至10年，平均8年的时间，对这17例患者进行了嗓音功能的临床和全面客观检查，包括频闪喉镜检查、电声门图检查、嗓音振荡测量、音域、发声时间、峰值流量和音高。仅有少数患者有一些不适，而嗓音功能的客观检查显示，除1例患者外，其余患者均有异常发现。接受早期嗓音训练的患者检查结果异常程度较轻。结论是，尽管客观检查结果异常，但所有17例患者对自己的嗓音功能都感到满意。此外，早期嗓音训练似乎为最大程度减少晚期嗓音问题提供了一个不错的机会，无论麻痹是永久性的还是暂时性的。
