title: Retrospective analysis of earlobe keloids treated with the carbon dioxide laser ablation or cold steel debulking surgery.
abstract: BACKGROUND
  Treatment of keloids is a therapeutic challenge.
  
  
  OBJECTIVE
  To determine the outcome and the risk of recurrence after debulking cold steel surgery or carbon dioxide (CO2) laser ablation of earlobe keloids.
  
  
  METHODS
  The case records of 16 patients with earlobe keloids managed at Changi General Hospital, Singapore, from 2003 to 2009 were reviewed retrospectively.
  
  
  RESULTS
  Fourteen patients were females, and the mean age at presentation was 20 years. Eight patients underwent CO2 laser ablation, six patients underwent cold steel surgery, one patient underwent both surgery and CO2 laser ablation, and one patient received only 40 mg/ml of intralesional triamcinolone acetonide. Fourteen patients were followed up for 1-24 months post procedure, and two patients defaulted. Both modalities were equally effective in debulking the earlobe keloids. All 13 patients who had either CO2 laser ablation or cold steel surgery had recurrence of keloid growth at 2-18 weeks post procedure. The patient who received intralesional triamcinolone acetonide therapy alone had only partial response to the therapy.
  
  
  CONCLUSIONS
  Both the CO2 laser ablation and cold steel surgery were equally useful in reducing the size of the earlobe keloids, but were not effective in preventing regrowth of the keloids, even with adjunctive intralesional steroids. Patients should be clearly counselled regarding this.
