摘　　要：目的通过音域图测试分析病理性嗓音、正常嗓音人群嗓音特点,并分析比较两组音域图测试相关参数指标之间的差异,从而探讨音域图测试在声带息肉中的应用价值。方法根据纳入、排除标准选择声带息肉患者120例,随机选择正常嗓音者60例。采用德国XION DIVAS系统中的音域图测试模式对两组受试者分别进行录制,分别测量在不同频率上所能发出的最低音与最强音,先获取低强度VRP曲线,再获取高强度VRP曲线。对声带息肉组及对照组的最大频率、最小频率、最大声强、最小声强及发声障碍指数各项数据进行统计学比较分析。结果与对照组相比,声带息肉组的平均最高频率降低(P=0.029 6),平均最小频率增高(P=0.000 3),频率范围减小(P=0.022 9),平均最大声强增高(P=0.003 9),最小声强值增高(P=0.0000),平均声强范围受限(P=0.006 9)。根据客观嗓音障碍指数分类,在频率方面,轻度嗓音障碍者在最大频率、最小频率、频率范围与对照组无明显差别;而中、重度嗓音障碍者平均最高频率比对照组降低,最小频率比对照组显著增高,频率范围比对照组明显受限。在强度方面,轻度嗓音障碍者在最大声强、最小声强、强度范围与对照组无明显差别;而中、重度嗓音障碍者平均最大声强、最小声强值比对照组均增高,但平均声强范围比对照组缩小。结论音域图测试可进行嗓音量化评定,可为临床辨别正常嗓音及病理性嗓音、评估嗓音损害严重程度提供客观依据,是嗓音功能检测的重要手段。Objective To analyze the pathological voice,normal voice range chart crowd voice characteristics through tests and analyze the differences between the two groups of test-related parameters chart range between indicators,so as to explore the value of the test range map in the polyp of vocal cord.Methods One hundred and twenty patients with vocal polyps according to inclusion and exclusion criteria were selected.Sixty cases of normal voice were randomly selected.Germany XION DIVAS system diagram test mode range were recorded for both groups,with the strongest voice of the bass were measured at different frequencies,first obtain low VRP intensity curve,then get high-intensity curve VRP.The maximum frequency of the vocal cord polyp group and normal control group,the minimum frequency,maximum intensity,most quietly strong,maximum phonation time,fundamental frequency perturbation and dysphonia index of the data were compared statistically.Results Compared with the control one,the mean maximum frequency of vocal cord polyp group were lower（P=0.029 6）,the average minimum frequency were significantly higher（P=0.000 3）,frequency range reduced（P=0.022 9）;vocal cord polyp average loudest group was stronger（P=0.003 9）,the whispered strength values were significantly higher（P=0.0000）,significantly limited the average sound intensity range than normal voice group group（P=0.006 9）.Classification index based on objective voice disorders,in terms of frequency,mild voice disorders at the maximum frequency.There was no significant difference in the minimum frequency,frequency range with a normal voice group;and in severe voice disorders average maximum frequency lower than the normal voice group,the smallest than normal voice frequency was significantly higher frequency range than the normal group was significantly limited.In terms of strength,mild impairment in the loudest voice is strong,most quietly strong.There was no significant difference with the normal voice group intensity range;and in severe voice d
