【摘要】：目的：探讨经外耳道声频共振导入利多卡因治疗感音神经性耳鸣的疗效。方法：选取2012年1-12月遵义医学院附属医院耳鼻喉科门诊就诊的感音神经性耳鸣患者39例(49耳),其中男16例,女23例,左耳29例,右耳20例,双侧耳鸣10例,患病时间3周以上,经临床常规治疗无效,治疗前后行纯音测听、耳鸣测试、声阻抗及耳声发射等检查。病例随机分为两组,治疗组导入2%利多卡因,对照组导入0.9%生理盐水。治疗期间未使用其他药物及物理治疗,观察耳鸣疗效。结果：利多卡因组有效率70.83%,生理盐水组有效率52.0%；两组间疗效差别有统计学意义(P0.05)。结论：经外耳道声频共振导入2%利多卡因治疗经临床传统治疗无效的感音神经性耳鸣效果明显,无不良反应,值得临床应用推广。
[Abstract]:Objective: to investigate the therapeutic effect of Lidocaine on sensorineural tinnitus treated by external acoustic resonance. Methods: 39 patients (49 ears) with sensorineural tinnitus (16 males, 23 females, 29 left ears, 20 right ears and 10 bilateral tinnitus) were selected from January to December 2012 in the Department of Otolaryngology, affiliated Hospital of Zunyi Medical College. The patients were ill for more than 3 weeks and had no effect after routine treatment. Pure tone audiometry, tinnitus test, acoustic impedance and otoacoustic emission were performed before and after treatment. The patients were randomly divided into two groups: 2% lidocaine in the treatment group and 0.9% saline in the control group. No other drugs and physiotherapy were used during the treatment, and the curative effect of tinnitus was observed. Results: the effective rate of lidocaine group was 70.83%, that of saline group was 52.0%, and there was significant difference between the two groups (P0.05). Conclusion: the treatment of sensorineural tinnitus with 2% lidocaine through external auditory canal resonance has obvious effect and no adverse reaction. It is worthy of clinical application and popularization of Lidocaine in the treatment of sensorineural tinnitus which is not effective in clinical treatment.
