Synopsis

Perichondritis is an infection of the soft tissue that encloses the auricular (ear) cartilage. It typically presents with erythema, edema, and tenderness in the pinna of the ear. Infection is usually bacterial in etiology, with bacteria introduced through local trauma. Pseudomonas aeruginosa and Staphylococcus aureus are the bacteria most commonly implicated. Relapsing polychondritis is a rare noninfectious disorder that mimics perichondritis. Perichondritis is treated with systemic antibiotics that include both pseudomonal and staphylococcal coverage. If untreated, infection may spread into the deeper cartilage of the ear ("chondritis"), causing more significant injury.
