摘要
①目的探讨声带息肉病人手术前后嗓音声学参数的变化与手术疗效的关系.②方法采用Dr.Speech软件对40例声带息肉病人术前、术后嗓音声学参数进行测试与比较.③结果 40例声带息肉病人术前声学参数值基频微扰、振幅微扰(shimmer)和声门噪声能量(NNE)均高于正常值;术后各项参数均有不同程度降低,术前与术后比较,差异均有极显著意义(F=101.09～125.27,q=14.17～23.86,P<0.01).术后第1周分别与术后第2周和第4周比较,各声学参数值差异均有显著性(q=4.34～7.79,P<0.01).术后第2周与术后第4周比较,各声学参数值差异无显著性(q=0.72～1.33,P>0.05).④结论嗓音声学检测中shimmer和NNE的声学参数值变化对手术前后疗效评估最有意义.
Objective To analyze the relationship between the effect of microlaryngoscopic surgery of vocal polyps and the changes of voice parameters. Methods Voice acoustic parameters of 40 patients with vocal polyps were measured by Dr. Speech software and compared with the normal voice before and after operation. Results The preoperative jitters, shimmer and NNE parameters were higher than those of the normal voice. All the postoperative parameters became significantly lower than the preoperative ones (F=101.09-125.27, q=14.17-23.86, P<0.01). The jitters, shimmer and NNE were different significantly between one week and two weeks or four weeks postoperatively (q=4.34-7.79, P<0.01), but not different significantly between two weeks and four weeks postoperatively (q=0.72-1.33,P>0.05). Conclusion The shimmer and NNE parameters are of great significance to evaluate the effect of microlaryngoscopic surgery of the vocal polyp.
