嗓音训练改善早期声带息肉患者发声功能的效果

Effect of Voice Training on Vocal Function for Patients with Early Vocal Fold Polyps

目的探讨嗓音训练改善早期声带息肉患者发声功能的临床效果。方法2016年5月至2018年5月,本院早期单侧广基型声带息肉患者80例随机分为对照组(n=40)和试验组(n=40)。两组均进行嗓音卫生宣教,试验组增加嗓音训练,每次40 min,每周1次,共12周。比较两组干预前后纤维喉镜下声带息肉大小、嗓音障碍指数(VHI)和嗓音客观分析等指标。结果对照组5例、试验组7例脱落。治疗后,试验组声带息肉治愈率和好转率显著高于对照组(χ2=24.608,P<0.001);试验组VHI各范畴评分均显著改善(t/Z>11.701,P<0.001),且显著优于对照组(t/Z>7.027,P<0.001);试验组基频微扰、振幅微扰和最长发声时间较治疗前显著改善(|t/Z|>5.012,P<0.001),且试验组均显著优于对照组(t/Z>4.596,P<0.001)。结论嗓音训练可以改善早期声带息肉患者的发声功能,降低嗓音嘶哑程度,改善患者的嗓音质量。

Objective To investigate the clinical effect of voice training on the vocal function of patients with early vocal fold polyps.Methods From May,2016 to May,2018,80 patients with unilateral wide-based vocal fold polyps were randomly divided into control group(n=40)and experimental group(n=40).Both groups underwent voice hygiene education,and the experimental group accepted voice training,40 minutes a week for twelve weeks in addition.They were evaluated with fiber laryngoscope,voice handicap index(VHI)and the computer phonatory detection before and after training.Results Five in the control group and seven in the experimental group were dropped out.After training,the cure rate and the improvement rate of vocal fold polyps were significantly higher in the experimental group than in the control group(χ2=24.608,P<0.001).The scores of VHI significantly improved in the experimental group(t/Z>11.701,P<0.05),and were better than those in the control group(t/Z>7.027,P<0.001).The scores of jitter,shimmer,and maximum phonation time improved(|t/Z|>5.012,P<0.001)after training in the experimental group,and were better than those in the control group(t/Z>4.596,P<0.001).Conclusion Voice training could improve the vocal function of patients with early vocal fold polyps,reduce hoarseness,and improve the voice quality.
