作者研究用皮质类固醇和抗生素结合经鼓室电离子透入治疗分泌性中耳炎(OME)之疗效。48例68耳3～6岁(平均4.7岁)OME患者随机分为两组。患者的鼓室压图均为B型,平均听力损失大于20dB。20倒33耳用0.4％地塞米松溶液与4％磷霉素溶液(盐水pH7.53)相同体积的混合液作电离子透入治疗,28例35耳未治作为对照组。电离子透入疗法一周作三次,每次16分钟,10次为一疗程。一月后检查 The authors studied the efficacy of corticosteroid and antibiotic combination tympanoskeleton iontophoresis in the treatment of secretory otitis media (OME). 48 cases of 68 ears 3 to 6 years (mean 4.7 years) OME patients were randomly divided into two groups. Patients with Tympanogram are B-type, the average hearing loss greater than 20dB. Twenty-three 33 ears were treated with 0.4% dexamethasone solution and 4% fosfomycin solution (saline pH7.53) in the same volume for iontophoresis. Twenty-five patients (35 ears) were untreated as control group. Iontophoresis three times a week, each 16 minutes, 10 times for a course of treatment. Check after January
