The clinical manifestations of acute otitis media and otitis media with effusion are the result of abnormal eustachian tube function most often caused by inflammation from infection or allergy. The majority of cases involve bacterial infection of the middle ear caused by Streptococcus pneumoniae, Haemophilus influenzae, or Branhamella catarrhalis. Nearly half of all children will have had at least one episode of acute otitis media by 1 year of age, and over 70% by 3 years of age. The signs and symptoms include pain with rubbing or tugging at the ear, fever, irritability, lethargy, and hearing loss. The primary therapy for acute otitis media and otitis media with effusion is antibiotics with the goal of preventing possible complications and providing symptomatic relief. Amoxicillin remains the initial drug of choice in communities where beta-lactamase-producing strains of the common middle ear pathogens are infrequently isolated. If resistant organisms are prevalent, cefaclor, amoxicillin-clavulanate, or cotrimoxazole should be selected. Adjuvant agents such as decongestants have not been shown to provide additional therapeutic benefit. Children who develop chronic otitis media may require prophylactic antibiotic therapy and insertion of typanostomy tubes.
急性中耳炎和分泌性中耳炎的临床表现是咽鼓管功能异常的结果,这种异常最常见的原因是感染或过敏引起的炎症。大多数病例是由肺炎链球菌、流感嗜血杆菌或卡他莫拉菌引起的中耳细菌感染。几乎一半的儿童在1岁时至少会患一次急性中耳炎,到3岁时这一比例超过70%。其体征和症状包括耳部揉搓或牵拉时疼痛、发热、易怒、嗜睡和听力损失。急性中耳炎和分泌性中耳炎的主要治疗方法是使用抗生素,目的是预防可能的并发症并缓解症状。在常见中耳病原体产β-内酰胺酶菌株很少分离出来的社区,阿莫西林仍然是首选的初始药物。如果耐药菌普遍存在,则应选择头孢克洛、阿莫西林-克拉维酸或复方新诺明。减充血剂等辅助药物尚未显示能提供额外的治疗益处。发展为慢性中耳炎的儿童可能需要预防性抗生素治疗并插入鼓膜造孔管。
