摘　　要：目的通过比较分析职业用嗓人群中有无声带病变者的音域图和嗓音疲劳测试结果差异,探讨其在评估该人群嗓音功能中的价值。方法选取2017年3月—2018年3月于重庆市人民医院耳鼻咽喉头颈外科就诊的职业用嗓者112例(包括主持人、销售员、教师、话务员及导购员等),根据症状和体征将其分为正常组和病理组,正常组无明显声嘶及发音障碍,检查声带无明显病变(如慢性声带炎、声带小结及声带息肉等),病理组有声嘶或发音障碍,检查声带存在病变。分别予以音域图和嗓音疲劳测试检查,量化评估两组嗓音功能。结果正常组最大声强、最高频率、最低频率、最长发声时间及嗓音障碍指数高于病理组(P<0.05),而最小声强、频率微扰低于病理组(P<0.05)。正常组嗓音疲劳测试失败率低于病理组(P<0.05)。正常组比病理组噪音疲劳测试失败率低(P<0.05)。结论音域图和嗓音疲劳测试指标可用于评估职业用嗓人群嗓音功能和嗓音疲劳状况,可作为评价其嗓音质量的重要手段。Objective To discuss the value to evaluate voice function in the group by comparing and analyzing the differences of voice range profile and voice fatigue test in occupational voice users who were with or without the vocal cord lesion. Methods According to inclusion and exclusion criteria, 112 occupational voice users were randomly divided into normal group and pathological group. There were no obvious hoarseness, dysphonia and vocal lesions (such as chronic vocal cord inflammation, vocal cord nodules, vocal cord polyps, etc) in the normal group. The pathological group had hoarseness, dysphonia or vocal cords. The voice range profile and voice fatigue test were separately examined to quantify the voice functions of the two groups. Results Compared with the normal group, the average frequency of the fundamental frequency perturbation increased (P < 0.05), the average minimum sound intensity increased (P < 0.05), and the failure rate of voice fatigue test increased (P < 0.05), but the average of the maximum sound intensity decreased (P < 0.05), the average of the maximum frequency decreased (P < 0.05), the average of the minimum frequency decreased (P =0.003), the average of maximum phonation time decreased (P < 0.05), dysphonia severity index decreased (P < 0.05) in pathological group. Conclusions The voice range profile and voice fatigue test are capable to evaluate the voice function and voice fatigue in occupational voice users, and can be used as important measures to evaluate the voice quality.
