Of 525 patients 17 (3.2%) showed a laryngoscopically established palsy of the recurrent laryngeal nerve after surgery due to goiter. A laryngoscopic follow-up of all these patients, performed at least one year after the operation, revealed that 76.5% of the recurrent nerve palsies were temporary and 23.5% were permanent. Danger of permanent palsy increased in the sequence--uncomplicated nodular goiter--struma maligna--recurrent goiter. The outcome of long-term follow-up showed a palsy rate of 0.8%, which was much lower than the corresponding rate reported by short-term control (p = 0.005). Therefore laryngoscopic long-term follow-up in cases of postoperative abnormal laryngoscopic function should be a standard part of follow-up in thyroid gland surgery.
在525例患者中，17例（3.2%）在因甲状腺肿行手术后经喉镜检查证实出现喉返神经麻痹。对所有这些患者在术后至少1年进行喉镜随访，结果显示76.5%的喉返神经麻痹为暂时性，23.5%为永久性。永久性麻痹的风险按以下顺序增加——单纯结节性甲状腺肿——恶性甲状腺肿——复发性甲状腺肿。长期随访结果显示麻痹发生率为0.8%，远低于短期对照报道的相应发生率（p = 0.005）。因此，对于术后喉镜功能异常的病例，喉镜长期随访应成为甲状腺手术随访的标准组成部分。
