声带显微手术后发声功能恢复和嗓音训练时间的初步探讨

Preliminary Study on Functional Recovery and Voice Training Time after Microsurgical Operation of Vocal Cords

目的:探讨声带显微手术后发声功能恢复和嗓音训练时间。方法:选取2011年1月-2014年4月本院耳鼻咽喉科收治的152例行声带显微手术的声带息肉患者为研究对象,采用嗓音声学分析,对其术前、术后3、5、7 d,各嗓音声学参数进行比较。按照抽签随机取样法将152例患者均分为两组,A组患者于手术后1周给予嗓音训练,B组患者于手术后2周给予嗓音训练。嗓音训练6个月后,比较两组患者各嗓音声学参数、VHI量表各项评分及GRBAS各项评分。结果:术后3 d,患者各声学参数均出现下降,但是与术前比较差异无统计学意义;从术后5 d开始,各声学参数均显著降低,与术前比较差异有统计学意义(P<0.05)。嗓音训练前,两组患者嗓音声学参数、VHI量表及GRBAS各项评分比较差异均无统计学意义,嗓音训练6个月后,两组患者嗓音声学参数、VHI量表及GRBAS各项评分均显著改善,且B组改善情况显著优于A组,比较差异有统计学意义(P<0.05)。结论:声带息肉患者显微外科手术后5 d嗓音质量开始恢复,但是术后2周内严格声休后方可进行嗓音训练。

Objective：To discuss the recovery of function and voice training time after microsurgical operation of vocal cords.Method：152 vocal cord polyps patients with vocal cord microsurgery from January 2011 to April 2014 in institute of otolaryngology department as research objects,using the voice acoustic analysis,compared to the voice acoustic parametersduring preoperative and postoperative 3,5,7 days.In accordance with the draw random sampling method 152 patients were divided into two groups,patients in group A at 1 weeks after surgery to give voice training,patients in group B at 2 weeks after surgery to give voice training.6 months after voice training,to compare the voice acoustic parameters,VHI scores and GRBAS scores of the two groups.Result：3 d after the operation,the acoustic parameters in patients decreased,had no significant difference compared with that before operation,from 5 d after operation,the acoustic parameters significantly decreased compared with that before operation,there were differences in statistical significance （P〈0.05）.Before voice training, two groups of patients with voice acoustic parameters,VHI scores and GRBAS scores had no significance,6 months after voice training,two groups of patients with voice acoustic parameters,VHI scores and GRBAS scores were significantly improved, group B improved more significantly than group A （P〈0.05）.Conclusion：The voice quality begin to restore 5 d after surgery in patients with vocal cord polyp microstructure,but patients within 2 weeks after a rigorous hugh rear can make voice training.
