显露喉返神经的甲状腺手术临床随机对照研究

CLINICAL RANDOMIZED CONTROL TRIAL OF EXPOSURE RECURRENT LARYNGEAL NERVE IN THYROIDECTOMY

目的研究显露喉返神经的甲状腺手术临床应用价值。方法将480例连续甲状腺手术病例随机分为显露喉返神经组(ERLN)与非显露喉返神经组(NERLN),对两组手术中及手术后喉返神经损伤情况进行对照研究。结果ERLN组与NERLN组损伤喉返神经致声带麻痹情况具有统计学意义(P<0.05),NERLN组喉返神经永久性损伤高于ERLN组(P<0.05)。结论显露喉返神经的甲状腺手术可以有效保护喉返神经并预防喉返神经的医源性损伤。

Objective To study the clinical value of exposure recurrent laryngeal nerve in thyroidectomy Methods Consecutive 480 patients requiring thyroidectomy were enrolled in this clinical randomized control trial. They were randomly divided into two groups： exposure recurrent laryngeal nerve （ERLN） group and non - exposure recurrent laryngeal nerve （NERLN） group by a sealed envelope method. Of 232 patients were exposed recurrent laryngeal nerve in thyroidectomy and 248 patients were not exposed recurrent suits ERLN group showed significantly fewer patients occurred recurrent laryngeal laryngeal nerve routinely. nerve palsy than NERLN group （ P 〈 0.05 ）. Both of temporary and permanent recurrent laryngeal palsy occurrence showed significant differences compared with the two groups （ P 〈 0. 05 ）. Conclusion Exposure recurrent laryngeal nerve is not only the effective measure for protection tomy. also for the best prevention of recurrent laryngeal nerve from medical injury in thyroidectomy.
