Recurrent Auricular Pseudocyst: Successful Treatment Using a Dental Silicon Cast

Abstract

Auricular pseudocysts (APs) are benign intercartilaginous cysts at the auricle. Various therapeutic options have been used to treat APs, but they frequently recur in usual clinical practice. Here, we report a case of AP successfully treated using a silicon cast. A 65-year-old male presented with a cyst on his right auricle. Although a local injection of steroid was administered, the cyst had recurred. A dental silicon cast was applied after removal of the contents of the cyst by suction. There was no recurrence of the cyst 6 years after that treatment. Dental silicon casts are a novel technique for an appropriate fixation over auricles in the treatment of APs and had an effective therapeutic result in our case.

Treatment of auricular pseudocysts using enhanced negative drainage: a prospective study of 21 cases

“…The critical aspect for the successful application of outer pressure are the forces on the uneven surface of the auricle as the auricular cartilage framework is three-dimensional. Dental silicone or plaster casts need to be held on the auricle for two to four weeks, 8 but it is easy for them to drop from the ear during movement or while sleeping; solid fixation also increases the risk of necrosis. Rubber sheets can apply equal pressure to auricular cartilage.…”
