甲状腺手术中喉返神经损伤的探讨

目的探讨研究甲状腺手术中喉返神经损伤的因素及预防措施。方法对在该院进行甲状腺手术的200例患者进行研究，200例患者中显露喉返神经患者49例，未显露喉返神经患者151例，统计所有患者发生喉返神经的几率。结果200例甲状腺手术患者共发生4例喉返神经损伤。发生几率为2．00％，其中不暴露喉返神经的手术方式发生损伤几率为0．66％，暴露喉返神经的手术方式损伤几率为6．12％，两者间差异有统计学意义（P〈0．05）。结论由于喉返神经的解剖部位复杂，所以在进行甲状腺手术时，注意喉返神经的解剖部位，术中小心操作，有助于减少喉返神经的损伤几率。

Discussion on Recurrent Laryngeal Nerve Injury in Thyroid Surgery

Objective To study the factors that cause recurrent laryngeal nerve injury in thyroid surgery and the prevention. Methods 200 cases of patients underwent thyroid surgery in our hospital were studied. Of the 200 cases, 49 cases had been re- vealed the recurrent laryngeal nerve, 151 cases had not. The incidence of recurrent laryngeal nerve injury of all the patients was counted. Results Recurrent laryngeal nerve injury occurred in 4 cases of the 200 cases, the occurrence probability was 2%. The incidence of recurrent laryngeal nerve injury by the surgical method that did not expose laryngeal nerve was 0.66%, but 6.12% by the surgical method that exposed laryngeal nerve, the difference was statistically significant （P〈0.05）. Conclusion Due to the re- current laryngeal nerve anatomical complexity, so during the thyroid surgery, the recurrent laryngeal nerve anatomy should be paid attention and the operation should be done carefully, which help to reduce the incidence of recurrent laryngeal nerve injury.
