title: Pseudocyst of the auricle: successful treatment with intracartilaginous trichloroacetic acid and button bolsters.
abstract: Pseudocyst of the auricle is an asymptomatic, noninflammatory cystic swelling that typically involves the anthelix of the ear and results from an accumulation of fluid within an unlined intracartilaginous cavity. We report a patient with a recurrent pseudocyst of the auricle and describe a new surgical technique for treating this condition by applying 50% trichloroacetic acid to the intracartilaginous cavity and utilizing external button bolsters for compressive therapy. This therapeutic approach is simple to perform in the office, results in permanent resolution of the pseudocyst, preserves the normal architecture of the external ear, and provides excellent postoperative and long-term cosmetic results.
