Objective To explore the significance of the Self -assessments of Voice Handicap Index (VHI) and The objective detection of Dysphonia Severity Index (DSI) in polyp of vocal cord perioperatively .Methods The Self -assessments of VHI had been completed in 28 patients with polyp of vocal cord before the operation and one week after the operation ,including function(F) ,physiological(P) ,emotion(E) ,and the sum denoted by T .In the meantime ,The DSI had been completed in these patients by acoustic analysis of DIVAS 2 .5 .After one month ,19 pa-tients had been re -examined .Results The DSI value was increasing ,but there was no significant difference be-tween pre-operation and one week after the operation(P>0 .05) ,indicating that the function of vocal cord was not recovered .In VHI scale ,the parameters were significantly different between the time preoperatively and one week postoperatively in F ,E and T(P<0 .05) ,howevre ,it was not significantly different in P(P>0 .05) ,indicating that the function of vocal cord was not completely recovered as same as the result of DSI .After one month ,there were significant differences in DSI and VHI ,which showed a full recovery of vocal cord fanction .Conclusion The Self -assessments of VHI and The objective detection of DSI in polyp of vocal cord can evaluate simultaneouly the function of laryngeal .Additionally ,there was a good correlation between the DSI and the VHI score .%目的探讨声带息肉患者手术前后嗓音障碍指数（voice handicap index ，VHI）量表自我评估和嗓音障碍严重指数（dysphonia severity index ，DSI）评估的价值。方法对28例声带息肉患者手术前及手术后1周、术后1月（19例）进行VHI量表自我评估，并运用DIVAS2．5声学分析软件评估DSI ，分析其结果。结果与术前比较，声带息肉患者术后1周DSI值升高，但差异无统计学意义（P＞0．05）；VHI量表中，功能F、情感E、总分T得分较术前降低，差异有统计学意义（P＜0．05），而生理P得分差异无统计学意义（P＞0．05）；术后1个月与术前比较， DSI值明显升高，VHI各项评分和总分均明显降低，差异均有统计学意义（P＜0．05）。结论声带息肉患者手术前后行VHI和DSI评估，能反映其术后嗓音恢复情况，两者有较好的一致性。
