Objective Research of the incidence of hyper functional dysphonic among the patients with polyps or nodules in vocal cord by analyzing the pictures and videos of laryngoscopy, and initially try to find out the necessity of vocal rehabilitation training for the patients after operations and also provide quantitative reference value for voice correction after vocal cord polyp surgery. Methods Choose 302 cases from almost 2000 patients with polyps or nodules in vocal cords, evaluate their laryngoscopic videos and concluding data. Results Hyper functional dysphonic was divided into four types by Koufman criterion according to the laryngoscopy results based on morphological, which was made by, type 1 41 cases(13.57%), type 2 23 cases(7.61%), type 3 38 cases(12.58%), type 4 19 cases(6.29%). Therefore, the ratios of hyper functional dysphonic was 121/302(40.6%).Conclusion Laryngoscopy is very helpful for evaluating and analysing hyper funtional dysphonic of the patients with polyps or nodules in vocal cord.%目的 ①通过电子喉镜检查声带息肉患者术前术后的喉镜视频及图像,归纳分析,探讨声带息肉患者中有高功能性发声障碍者的发生概率.初步分析嗓音发声训练对于声带息肉术后嗓音治疗的必要性.②为声带息肉手术后进行嗓音矫治提供量化参考数值.方法 对2006年10月～2010年1月期间,302例年龄在20～68岁声带息肉患者进行喉镜检查,观察喉部视频及图像特征,评价并做分析.结果 对喉镜检查结果根据形态特点以KOUFMAN标准将高功能性发声障碍分为四种类型其中Ⅰ型41例占13.57%,Ⅱ型23例占7.61%,Ⅲ型38例占12.58%,Ⅴ型19例占6.29%(共121例).高功能性发声障碍比例为121/302,占40.06%.结论 采用喉镜检查有助于对声带息肉患者进行嗓音评价,以决定是否术后进行嗓音矫治.
