甲状腺手术方式和喉返神经损伤的关系

目的探讨甲状腺手术方式与喉返神经损伤的关系。方法回顾性分析2000例甲状腺手术方法与喉返神经损伤的关系。结果喉返神经损伤19例，损伤率为0．95％（19／2000），永久性损伤率为0．35％（7／2000）；喉返神经显露组损伤率0．36％（6／1680）明显低于非显露组的0．86％（13／1520）（χ^2=4．20，P〈0．05）。行甲状腺部分切除、侧叶次全切除、侧叶完全切除及同侧淋巴结清扫者喉返神经损伤率依次增高。甲状腺再次手术神经损伤。结论甲状腺手术方式及切除范围与喉返神经损伤明显相关（r=0．652，P〈0．05）。

Recurrent laryngeal nerve injury and thyroid surgery in thyroidectomy

Objective To explore the relationship between recurrent laryngeal nerve injury (RLN)and thyroid surgery. Methods Comparison of surgery methods and relationship with RLN injury in 2000 cases of thyroidectomy. Results The overall incidence of recurrent laryngeal nerve injury was 0. 95% (19/2000) and incidence of permanent damage was 0.35% (7/2000). The injury incidence in the nerve exposure (0.36%, 6/ 1680) was significantly lower than non-exposure (0.86% , 13/1520) (χ2 = 4.20, P < 0.05). The injury rates of partial lobectomy, subtotal lobectomy, lobectomy and lobectomy plus ipsolateral neck dissection increased in sequence. Conclusion The surgery method is significantly related with RLN(r =0.652,P<0.05).
