Auricular perichondritis developed in a patient following acupuncture to the pinna. Poor response to high-dose antibiotics necessitated open drainage. The underlying cartilage was uninvolved, and minimal deformity ensued. Acupuncture must be considered a form of penetrating trauma that may induce a perichondritis or chondritis in the auricle.
