加入背景音的复合声治疗不同频率失代偿性耳鸣的疗效分析

Effect of combined acoustic therapy with background sound on decompensated tinnitus with different frequencies

目的探讨加入背景音的复合声治疗对各频率失代偿性耳鸣的治疗效果,以及耳鸣频率与治疗效果的关系。方法研究对象为就诊于耳鼻咽喉科门诊的失代偿性耳鸣患者130例,其中脱落6例,病程均>6个月。完善耳科检查及听力学检查,将患者随机分为试验组和对照组,试验组给予加入了背景音的复合声治疗,对照组单独给予复合声治疗,进行为期30d声治疗。同时根据患者耳鸣频率再将试验组患者分为低频组、中频组、高频组。用耳鸣致残量表(THI)和焦虑自评量表(SAS)来评价治疗效果,并比较各组间的差异。结果 124例(试验组65例,对照组59例)完成了本次试验。两组治疗后THI评分和SAS评分均下降,与治疗前相比有统计学差异。治疗后两组间的THI评分相比无统计学差异,然而试验组的SAS评分低于对照组。试验组中低频组治疗后THI评分低于高频组。SAS评分各频率组间无统计学差异。结论加入或不加入背景音的复合声治疗都能改善失代偿耳鸣患者的症状。加入背景音的复合声治疗能更好地改善患者的焦虑症状,而且对低频耳鸣患者的症状改善更明显。

Objective To explore the therapeutic effect of complex sound therapy on decompensated tinnitus with different frequencies.Methods One hundred and twenty-four patients with decompensated tinnitus for more than6 months were admitted to the otolaryngology clinic.Following ear and audiology examinations,patients were randomly divided into an experimental group and a control group.The experimental group received combined acoustic therapy with background sound,while the control group received combined acoustic therapy alone for30 days.According to the patient's tinnitus frequency,the experimental group was further divided into low-,medium-,and high-frequency subgroups.All the patients were evaluated before and after treatment using the Tinnitus Handicap Inventory(THI)and the Self-Rating Anxiety Scale(SAS).Results THI and SAS scores significantly decreased after treatment in both the groups.There was no significant difference in THI scores between the groups.However,SAS scores were significantly lower in the experimental group than in the control group.Post-treatment THI scores were significantly lower in the low-frequency subgroup than in the high-frequency subgroup.Conclusion Combined acoustic therapy with or without background sound can improve decompensated tinnitus symptoms.Combined acoustic therapy with background sound can improve decompensated tinnitus-associated anxiety symptoms and is,particularly,helpful for symptomatic relief in patients with low-frequency tinnitus.
