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.
