摘要: 目的:探讨个性化定制的多元复合声对慢性主观性耳鸣的治疗效果,以及耳鸣频率、听力损伤"切迹"与治疗效果的关系。方法:研究对象为就诊于我院眩晕耳鸣门诊的慢性主观性耳鸣患者78例,其纯音测听阈值正常,均接受了3个月的个性化定制复合声治疗。治疗前对其进行精细化听力学检测(包括精细化纯音测听、耳鸣匹配、残余抑制),并于治疗前、治疗第30天和第90天进行耳鸣残疾量表评估(THI)。结果:①78例患者,治疗前THI评分为24.62±15.65,治疗第30天为15.82±13.02,第90天为13.62±10.98,治疗第30天、第90天的THI评分较治疗前均显著性下降(P<0.01),但第30天和第90天的THI评分差异无统计学意义(P>0.05)。②耳鸣患者的性别、年龄及耳鸣侧别对耳鸣的个性化复合声治疗的疗效无影响(P>0.05)。③78例患者的精细化纯音听阈测试,有损伤"切迹"的31例,无"切迹"的47例,2组之间的THI评分在治疗第30天和第90天差异均无统计学意义(P>0.05),提示纯音测听损伤"切迹"对耳鸣的个性化复合声治疗的疗效无影响。④31例有切迹的患者,22例耳鸣频率位于"切迹"频率范围内,9例位于"切迹"频率范围之外,治疗第30天2组之间的疗效差异有统计学意义(P<0.05)。治疗第30天,有4例"切迹"在耳鸣频率之外的患者耳鸣频率发生改变,漂移至切迹频率范围之内,其频率漂移在治疗第90天有显著性差异(P<0.05)。结论:个性化定制的复合声治疗能够降低慢性主观性耳鸣患者的THI评分,改善由于耳鸣症状产生的影响和困扰,且耳鸣频率分布在听力损伤频率范围的患者声治疗效果较好。Abstract: Objective: To explore the effect of individualized multi-compound sound therapy on chronic subjective tinnitus and the relationship between tinnitus frequency, "notch" hearing loss and the treatment effect of sound therapy. Method: Seventy-eight cases of chronic subjective tinnitus with the pure tone test threshold (PTA)in normal range (≤ 25 dB HL)were enrolled in this study. Their hearing threshold were re-evaluated using the precise pure-tone audiogram (P-PTA). Tinnitus was evaluated on pitch and loudness matching, and the effectiveness of tinnitus was measured using Tinnitus Handicap Inventory (THI) before they received the individualized customized multi-compound sound therapy for 3 months. THI were re-evaluated on the 30th day and 90th day after treatment. Result: ①The averaged THI score of these patients before the sound treatment was 24.62±15.65 (n=78). The score dropped significantly to 15.82±13.02 and 13.62 ±10.98 on the 30th day and 90th day after treatment, respectively (P<0.01). ②Patient's gender, age, and the side of tinnitus has no effect on the sound treatment of tinnitus. ③Of these 78 tinnitus patients, 31 patients who showed "notch" hearing loss and 47 patients without "notch" hearing loss in the P-PTA. The averaged THI score between the patients with and without "notch" showed no statistical difference after the treatment (P>0.05). These data suggested that "notch" hearing loss in P-PTA has no effect on the sound therapy.④Of 31 tinnitus patients with "notch" hearing loss, the tinnitus frequency of 22 cases was at the "notch" hearing loss and that of 9 cases was not at the "notch" hearing loss. Sound treatment showed significant between the former and the latter(P<0.05). After 30 days of treatment, tinnitus frequency of four patients whose tinnitus was not at the notch hearing loss drifted to the "notch" hearing loss frequency.Conclusion: Customized multi-compound sound therapy can reduce the THI score of chronic subjective tinnitus patients. The treatment reduced patient's anxiety and improved their quality of life. Sound treatment showed a better improvement in the patients whose tinnitus frequency was located at their notch hearing loss.
