[Keloid scars of the external ear: a non solved problem].

The external ear is a location with high risk of keloid scar formation. Its incidence is growing since general use of piercings and performance of plastic surgery of the external ear. The external ear keloid can be a devasting process for adolescent population which is worried about their appearance. Our aim is to attract attention about the risk of keloid scars of the external ear, reviewing our experience. After dismissing radiotherapy, corticoid infiltration and surgical removal are the most used options, with a high recurrence risk. We have reviewed traumatic, surgical and piercing wounds of the external ear, with a subsequent keloid formation treated in our outpatient clinic, collecting data about wound etiology, treatment and results. During the last 10 years we have found 11 keloid scars, 2 of them improved with topical corticosteroid. Treatment has been surgical in 9 cases, 4 of them with skin graft: 5 recovered and 4 recurred; 2 of them were reoperated. 2 of them were treated with intralesional corticosteroid solely, one recovered and the other one had improved. Treatment management of keloid scars is complex and there isn't a procedure with superior results than the others. Risk of complication must be explained within adolescent population.
