目的 观察和比较地塞米松鼓室内注射对低频下降型突发性聋的疗效.方法 70例(70耳)常规方法治疗无效的低频下降型突发性聋患者作为研究对象,分为2组,治疗组36例,对照组34例.治疗组:地塞米松磷酸钠注射液(1 mL:5 mg)鼓室内注射,每次注射0.8 mL.每周2次,共4次(疗程为2周).对照组:为同期常规方法治疗无效且拒绝鼓室用药的突发性聋患者,口服银杏叶片(每日3次,每次1片).治疗完成后1个月纯音测听检查,比较两组听力恢复及并发症情况.结果 治疗组的痊愈、显效、有效、无效的例数分别为16、6、7、7例,总有效率80.6%(29/36),对照组的痊愈、显效、有效、无效的例数分别为4、2、10、18例,总有效率47.1%(16/34),治疗组优于对照组,差异有统计学意义(P<0.05).结论 鼓室内注射地塞米松补救性治疗低频下降型突发性聋安全有效.“,”Objective To observe and compare the efficacy of intratympanic dexamethasone perfusion for acute low-tone sensorineural hearing loss (ALHL) after failure of initial therapy. Methods 70 patients (70 ears) underwent an ineffective treatment of ALHL after failure of initial management. Patients were divided into two groups. The treatment group included 36 cases, they all had received intratympanic dexamethasone (l mL: 5 mg, 0.8 mL), 2 times a week, a total of 4 times (Treatment for 2 weeks). Control group included 34 patients who refused to intratympanic dexamethasone perfusion took oral ginkgo lamina tablet. Results The cases of recovery, markedly effective, effective and invalid in treatment group were 16, 6, 7, 7. The total effective rate was 80.6% (29/36), was better than that of control group, 47.1% (16/34), the difference was statistically significant. Conclusion Intratympanic dexamethasone perfusion as the salvage treatment for ALHL is safe and effective.
