渗出性中耳炎是引起儿童听力损失的最常见的原因。目前,尚未建立一种统一的有效的治疗方案。过去,认为此病是一无菌过程,近来,已有数家鉴定出中耳渗液中的细菌与急性中耳炎中所见相同。作者设计了有对照的临床试验,以评价抗菌治疗的效果。 Exudative otitis media is the most common cause of hearing loss in children. At present, a unified and effective treatment plan has not been established yet. In the past, the disease was considered as a sterile process. Recently, several bacteria identified in the middle ear effusion have been identified as seen in acute otitis media. The authors designed a controlled clinical trial to evaluate the efficacy of antimicrobial therapy.
