声带息肉伴咽喉反流患者手术前后嗓音客观分析

目的探讨声带息肉伴咽喉反流患者手术前后嗓音客观分析指标的变化。 方法采用德国艾克松(XION)嗓音学分析软件，对34例声带息肉伴咽喉反流患者手术前后进行嗓音学分析。 结果声带息肉组术后与术前的基频微扰(Jitter)、振幅微扰(Shimmer)、声压级(SPL)、发声最长时间(MPT)、反流体征量表(RSI)及反流症状量表(RFS)各指标的差异均有统计学意义(P<0.05)；最大基频(Fomax)、最小基频(Fomin)、发音障碍严重指数(DSI)前后差异均无统计学意义。 结论嗓音学分析可客观、定量地分析声带息肉嗓音质量，并评估手术疗效。

Application of voice acoustic analysis in the evaluation of the effect of vocal cord polyp and plaryngopharyngeal reflux operation

ObjectiveThe purpose of this paper is to investigate the changes in voice Voice acoustic analysis, particularly before and after the vocal cord polyp and plaryngopharyngeal reflux operation. MethodsDetailed information has been acquired by the author using the German Axon(XION)voice analysis software, which was used to do the voice acoustic analysis, 34 cases of comparisons have been performed to analyse the different indexes before and after the vocal cord polyp and plaryngopharyngeal reflux operation. ResultsFeedback is based on the results of those comparisons.The vocaI cord polyp group indexes consisted of six parts, Which are jitter, amplitude perturbation(shimmer), sound pressure level(SPL)and MPT、RSI、RFS.Those indexs were considerably different from the normal control group(P<0.05). Meanwhile, data suggested that Fundamental frequency(F0)and DSI had no evident change in the parameter values. ConclusionThese findings of the research have naturally led the author to the conclusion that the aconsic analysis can reflect the vocal cord polyp voice quality objectively and quantitatively.therefore, it can evaluate the effect of operation.
