目的观察经咽鼓管鼓室注入地塞米松治疗突发性聋(突聋)的疗效。方法对20例常规方法治疗无效的突聋患者采用经咽鼓管鼓室径路注入地塞米松,1次/周,每次5mg,共3次。用药期间密切观察记录听力改变、耳鸣和眩晕等情况。结果20例患者于治疗完成后一周复查纯音测听。显效8例,0.25～4kHz听阈平均提高35.4dB;有效1例,平均提高14dB;无效11例;有效率为45%。结论鼓室内应用激素能改善常规治疗无效的突发性聋患者的听力。为常规方法治疗无效的突聋患者提供了再次治疗的机会。
Objective To observe the curative effect of sudden deafness (sudden deafness) treated by intratympanic intrathecal injection of dexamethasone. Methods Twenty patients with sudden deafness who were ineffective in the conventional treatment were injected with dexamethasone via the eustachian tube tympanoskeleton, once a week for 5 times for 3 times. Close observation during the recording of hearing changes, tinnitus and dizziness and so on. Results 20 patients in the week after the completion of treatment review tone audiometry. 8 cases were markedly effective, and the hearing threshold was increased by 35.4dB on average in 0.25 ~ 4kHz; 1 case was effective, the average increase was 14dB; 11 cases were ineffective; and the effective rate was 45%. Conclusion The application of hormones in the tympanic cavity can improve the hearing ability of patients with sudden deafness who are ineffective in conventional treatment. This provides an opportunity for re-treatment of patients with sudden deafness who are ineffective in the conventional treatment.
