Following otitis media, 10% to 50% of children develop residual middle ear effusion with concurrent hearing loss and potential cognitive, behavioral, and language impairment. Prophylactic antibiotics and tympanostomy tubes are currently recommended treatments for chronic middle ear effusion.
In a double-blind, placebo-controlled, randomized study of chronic middle ear effusion, we assessed the effectiveness of topical intranasal beclomethasone as an adjunct to prophylactic antibiotic therapy.
Sixty-one children, aged 3 to 11 years with persistent middle ear effusion greater than 3 months, were randomized into three treatment groups: (1) prophylactic antibiotics; (2) prophylactic antibiotics plus intranasal beclomethasone (336 micrograms/day); and (3) prophylactic antibiotics plus intranasal placebo. Patients were evaluated with aeroallergen skin tests at entry; and tympanogram, otoscopic examination, and symptom questionnaire at 0, 4, 8, and 12 weeks.
While middle ear pressures, otoscopic examinations, and symptom scores were improved for each treatment group over 12 weeks of therapy, the beclomethasone plus antibiotics group improved all three measures more rapidly than the antibiotics-alone and placebo nasal spray plus antibiotics groups over the first 8 weeks. Only the beclomethasone group significantly improved left (P = .004) and right (P = .01) middle ear pressures over 12 weeks. Resolution of chronic middle ear effusions was more frequent in the beclomethasone group (P < or = .05 at 4 and 8 weeks). No difference in response to nasal steroids was observed between atopic and nonatopic subjects.
We conclude that intranasal beclomethasone may be a useful adjunct to prophylactic antibiotic treatment of chronic middle ear effusion.
中耳炎发作后,10%至50%的儿童会出现残留中耳积液,并伴有听力损失以及潜在的认知、行为和语言障碍。预防性使用抗生素和鼓膜置管是目前治疗慢性中耳积液的推荐方法。
在一项针对慢性中耳积液的双盲、安慰剂对照、随机研究中,我们评估了鼻内局部使用倍氯米松作为预防性抗生素治疗辅助手段的有效性。
61名3至11岁、中耳积液持续超过3个月的儿童被随机分为三个治疗组:(1)预防性抗生素组;(2)预防性抗生素加鼻内倍氯米松(336微克/天)组;(3)预防性抗生素加鼻内安慰剂组。患者在入组时进行气传变应原皮肤试验;并在0、4、8和12周时进行鼓室图、耳镜检查和症状问卷调查。
在12周的治疗过程中,每个治疗组的中耳压力、耳镜检查结果和症状评分均有所改善,但在治疗的前8周,倍氯米松加抗生素组在这三项指标上的改善速度比单纯抗生素组和安慰剂鼻喷雾剂加抗生素组更快。只有倍氯米松组在12周内使左耳(P = 0.004)和右耳(P = 0.01)的中耳压力有显著改善。倍氯米松组慢性中耳积液的消退更为频繁(在4周和8周时P≤0.05)。特应性和非特应性受试者对鼻用类固醇的反应没有差异。
我们得出结论,鼻内使用倍氯米松可能是慢性中耳积液预防性抗生素治疗的一种有用辅助手段。
