甲状腺腺叶切除术中显露喉返神经的意义

THE SIGNIFICANCE OF EXPOSING THE RECURRENT LARYNGEAL NERVE DURING TOTAL THYROID LOBECTOMY

目的 :探讨显露喉返神经在甲状腺腺叶切除术中的意义。方法 :按是否于术中显露喉返神经随机将91例需行单侧甲状腺腺叶切除术的患者分为显露组与非显露组 ,记录手术时间和术中出血量 ,观察术后发音和喉镜检查情况。结果 :42例显露组中术后无一例发生声嘶和喉镜检查异常 ,49例非显露组中 6例发生声嘶 ,7例喉镜检查异常 ,两组比较有显著性差异 (P <0 0 5 ) ;两组手术时间和术中出血量比较无显著性差异 (P >0 0 5 )。结论 :在单侧甲状腺腺叶切除术中显露喉返神经可以有效地防止喉返神经的损伤。

Objective:To study the significance of exposing the recurrent laryngeal nerve during total thyroid lobectomy. Methods:91 cases who needed thyroid lobectomy were divided into exposure group and non-exposure group randomly according to the exposure of the recurrent laryngeal nerve during the operation. The operation time and the volume of hemorrhage were recorded, and the vocalization and the results of laryngoscopy of patients were examined. Results:No hoarseness and abnormality of laryngoscopy were observed in the exposure group contained 42 cases. In the non-exposure group, which was comprised of 49 cases, hoarseness was observed in 6 cases and the abnormality of laryngoscopy was found in 7 cases. The differences were significant(P<0 05). Whereas the differences of the operation time and the volume of hemorrhage between the two groups were not significant(P>0 05). Conclusion:Exposure of the recurrent laryngeal nerve during total unilateral thyroid lobectomy can prevent the damage of the recurrent laryngeal nerve effectively.
