Background: Xanthelasma palpebrarum (XP) is a metabolic disorder involving the eyelids. Radiofrequency(RF) surgery and trichloroacetic acid (TCA) applications have been listed among the procedures for XP, but comparative studies are not available. Aim: To compare the efficacy of radiofrequency surgery versus trichloroacetic acid application in the treatment of XP. Settings and Design: 20 consecutive cases of XP attending dermatology, medicine and endocrinology out-patient departments of M.S.Ramaiah teaching hospital were enrolled for the study. It was an open-label clinical trial conducted in our hospital for a duration of 1 year. Materials and Methods: 20 consecutive patients conforming to inclusion criteria were selected for the study. For each patient, lesions were treated with radiofrequency ablation on one side and TCA application on the other side. Results: RF ablation was done for 12 patients over right eye lesions and 8 patients over the left eye lesions. TCA applications were done for 8 patients over right eye lesions and 12 patients over left eye lesions. 70% of lesions treated with RF ablation had a score of improvement of 4 and 70% of lesions treated with TCA application had a score of improvement of 4, at 4 weeks of follow-up. At four weeks of follow-up 40% in RF group and 15% in TCA group had scarring and 45% in RF group and 30% in TCA group had pigmentation. Conclusion: RF ablation as compared to TCA application, required fewer sessions for achieving more than 75% clearance of lesions. However, TCA applications were associated with fewer complications comparatively.
