外耳道感染（外耳道炎）与其他部位的皮肤和软组织感染相似。由于椎管狭窄且弯曲，会出现独特的问题;液体和异物进入，被困，并引起浅表组织的刺激和浸渍。由于发炎组织扩张的空间有限，导致的疼痛和瘙痒可能会很严重。外耳道感染可分为四类：急性局限性外耳道炎、急性弥漫性外耳道炎、慢性外耳道炎和恶性外耳道炎。Senturia及其同事、1 Hirsch、2以及Rubin和Yu 3的评论提供了更完整的信息。
OTITIS EXTERNA Infection of the external auditory canal (otitis externa) is similar to infection of skin and soft tissue elsewhere. Unique problems occur because the canal is narrow and tortuous; fluid and foreign objects enter, are trapped, and cause irritation and maceration of the superficial tissues. The pain and itching that result may be severe because of the limited space for expansion of the inflamed tissue. Infections of the external canal may be subdivided into four categories: acute localized otitis externa, acute diffuse otitis externa, chronic otitis externa, and malignant otitis externa. Reviews by Senturia and co-workers, 1 Hirsch, 2 and Rubin and Yu 3 provide more complete information.
