Assessment of efficacy and tolerability of different concentrations of trichloroacetic acid vs. carbon dioxide laser in treatment of xanthelasma palpebrarum

BackgroundThere are numerous methods currently available for the management of xanthelasma. These include surgical excision, laser ablation using a variety of lasers and chemical cauterization. However, each method of treatment is associated with particular limitations and side effects. ObjectivesTo assess the clinical efficacy and tolerability of different concentrations of topical trichloroacetic acid (TCA) vs. carbon dioxide laser in the treatment of patients with xanthelasma palpebrarum. MethodsThirty patients with xanthelasma palpebrarum were classified into four groups, treated by TCA 35%, 50%, 70%, and CO2 laser, respectively. Lipid profile was estimated for all patients. ResultsBoth TCA peeling 70% and carbon dioxide laser ablation showed more significant clinical efficacy and tolerability with least number of sessions in the treatment of xanthelasma palpebrarum than 50% and 35% TCA peeling. Post-therapy erythema and hypopigmentation were more with TCA 70%. Post-therapy hyperpigmentation was more with TCA (50%). There was a significant improvement in patients with normal lipid profile than those with abnormal profile. ConclusionBoth TCA peeling 70% and carbon dioxide laser ablation are highly effective and well tolerated with least number of sessions in the treatment of xanthelasma palpebrarum.
