Protocolo de tratamiento de cicatrices queloides en el pabellón auricular del Hospital General Dr. Manuel Gea González

keloid scars are one of the most difficult pathologies to treat because its high rate of recurrence, from 100 % with single treatment to 50 % with combined therapy. the auricle is a frequent localization of keloids. we report our experience in the last 6 years with combined therapy in 51 patients and 64 auricles with keloid scars.: all scars were injected with triamcinolone or betamethasone 3 times with 4-6 weeks between each injection. four weeks after the last injection, the keloids were excised and skin closure was done without tension. in those patients with history of surgical excision, we added to the treatment colchicine, 1 mg daily, for 8 weeks with hepatic function test before and after the administration of colchicine. the keloid was unilateral in 74.5 % of the cases; 56.8 % females; the age of presentation was between 8 and 61 years old, with a media of 24 years old.the right auricle was affected in 65 % and the most frequently affected area was the lobule in 42 %.the etiology in 56 % of the cases were secondary to piercing. in 18.6 % of the cases the scar was resolved with the intralesional injection of triamcinolone or betametasone. from the 48 excisions performed, 12.5 % (6 keloid scars) presented recurrence, with a follow up of 8 months to 6 years.
