title: In-situ irradiation of keloid scars with Nd:YAG laser.
abstract: In-situ coagulation of keloid with Nd:YAG laser irradiation was carried out in in a cohort study of 17 patients, each with one keloid scar situated on either the sternum (six), abdomen (seven), shoulder (two), hip (one), or ear lobe (one). The duration of scarring was three to 17 years and size varied from 3-8 cm long. One to two doses of laser irradiation was required for complete coagulation. At three months, 10 (58.8%) keloids had completely healed; but in seven (41.1%), 25-50% of residual keloid persisted. Intralesional triamcinolone injection, once in four patients and twice in three patients, produced complete resolution in all seven patients. At 18 months to five years follow-up, 14 patients remain keloid-free but in three keloid recurred and was re-treated with laser coagulation with complete resolution. The treatment was carried out as an outpatient procedure under local anaesthesia. There were no complications. The results of this initial study suggest that Nd:YAG laser irradiation coagulation is effective treatment for keloid scarring.
