目的 探讨甲状腺手术方式和喉返神经损伤（RLN）的关系。 方法 回顾性分析2009年1月至2012年6月期间于笔者所在医院科室接受开放性甲状腺手术的985例患者的临床资料，探讨甲状腺手术方式和RLN损伤的关系。 结果 本组患者术后发生RLN损伤26例（2.6%），未发生RLN损伤959例（97.4%）。logistic回归分析结果显示，年龄、性别、超声刀应用、麻醉方式及肿块良恶性与RLN损伤均无关（P＞0.05），而手术范围（OR=3.726，P=0.007）和显露RLN（OR=0.302，P=0.006）则是RLN损伤的影响因素，行扩大性手术及未显露RLN者的RLN损伤率较高。 结论 在开放性甲状腺手术中，手术范围以及显露RLN是RLN损伤的独立影响因素，术中显露并注意保护RLN，对避免RLN损伤具有重要意义。
Objective To explore the relationship between external branch of superior laryngeal nerve (EBSLN) injury and the approachs of surgery in open thyroidectomy, and to summarize the preventive methods. Methods The clinical data of 985 patients who had consecutively underwent open thyroidectomy from January 2009 to June 2012 were retrospectively analyzed, to explore the relationship between EBSLN injury and the approachs of surgery in open thyroidectomy. Results The overall incidence of EBSLN injury was 2.6% (26/985), and 959 patients (97.4%) didn’t suffered from EBSLN injury. Results of logistic regression showed that the extent of surgery (OR=4.536, P=0.004) and identification of the EBSLN (OR=0.126, P=0.044) were influence factors of EBSLN injury after open thyroidectomy, but age (OR=1.108, P=0.823), gender (OR=0.604, P=0.260), benign or malignant tumor (OR=1.871, P=0.186), anesthesia methods (OR=0.659, P=0.372), and the application of ultrasonic scalpel (OR=0.473, P=0.248) were not associated with EBSLN injury. Conclusion In open thyroidectomy, the extent of surgery and identification of EBSLN are the independent factors of EBSLN injury, which are important to avoid EBSLN injury.
