Treatment of auricular pseudocyst with aspiration and local pressure.

Abstract

An auricular pseudocyst is a fluid filled cavity unlined by epithelium in the intracartilaginous space of the ear. Clinically, it presents as a painless outpouching on the upper anterior surface of the auricle with sterile straw coloured fluid found upon aspiration. If left untreated, permanent deformity of the pinna may result. Treatment of the pseudocysts has varied in the literature with techniques involving aspiration alone or incision and drainage; however, due to the high recurrence rates with these methods more aggressive therapies have been instituted. Although these techniques have achieved reasonable results with few recurrences, their invasive nature and chemotherapeutic and toxic agents used have caused significant morbidity. We present treatment of an auricular pseudocyst by simple aspiration and local pressure application using an auricular prosthesis formulated with the creation of a moulage fitted to the ear by our prosthetist. This minimally invasive and simplistic approach can avoid some of the complications related to other therapies, such as cartilage deformity, depigmentation of skin, and scarring and yields optimal cosmetic results.
