中文摘要：

目的：探讨喉返神经显露技术在甲状腺癌手术中应用的意义。方法：对2009年8月至2012年8月本科收治的甲状腺癌患者112例,术中常规探查双侧喉返神经后行甲状腺全切术并行患侧Ⅵ区淋巴结廓清术，探讨手术治疗效果及防止喉返神经损伤的方法。结果：所有患者均成功探查双侧喉返神经，共224条，甲状腺腺体及癌肿包块完整切除。术后7例出现单侧声带活动障碍，5例患者1年内恢复正常，2例未恢复正常,无肿瘤复发病例。结论：甲状腺癌术中探查喉返神经有助于腺体及癌肿的完整切除，是防止术后喉返神经麻痹的有效方法，对保证患者术后生活质量具有重要意义。

英文摘要：

Objective：To discuss the significance of the laryngeal recurrent nerve exposure during the thyroid gland carcinoma operation.Methods：From August 2009 to August 2012,112 cases of the thyroid gland carcinoma patients hospitalized in otorhinolaryngology-head and neck department,we routinely probed the bilateral laryngeal recurrent nerve,held Ⅵ region lymph node dissection during the operation and explored the ways for the precaution of laryngeal recurrent nerve injury and discussed the operating effect.Results：The 112 cases patients bilateral laryngeal recurrent nerve were all successfully probed during the operation,totally 224 laryngeal recurrent nerve and the thyroid gland,carcinoma lump totally removed during the operation.7 cases occurred the unilateral vocal cord paralysis after the operation and 5 cases recovered in the follow-up of 1 year,2 cases without recovered.During the follow-up in 1 year without the recurrent cases were found.Conclusion：During the operation of thyroidectomy in thyroid gland carcinoma,the laryngeal recurrent nerve exposure is conductive to the totally resection of the thyroid gland and carcinoma lump,it is an effective method for the precaution of the postoperative laryngeal recurrent nerve paralysis and of high significance in guaranting the postoperative life quality.
