In this time, 38 patients (7 males and 31 females, 41 cases, 57 ears) with ear keloid, who visited our hospital from January 2003 to March 2008, were studied. Their treatment methods and recurrences were investigated.
Operation was performed on 29 patients (31 cases, 46 ears), operation only in 21 (30 ears) and a combination of operation and irradiation in 10 (16 ears). Recurrence was observed in 5 cases (8ears) with no irradiation in all the cases. The recurrence rate was 26.7% in operation only and 0% in the combination. Early side effects of irradiation therapy such as pigmentation were not observed in any irradiated cases.
Since the patients with ear keloid are relatively young and the recurrent rate is not so high in operation only, we recommend not to indicate irradiation in the initial operation for ear keloid and to adopt postoperative irradiation only in re-operation of recurrent cases.
