Trichloroacetic Acid 90% versus Radiofrequency Ablation in the Management of Facial Seborrheic Keratoses: A Prospective Interventional Study

Introduction: Seborrheic Keratoses (SK) are commonly encountered benign epidermal tumors characterized by well-demarcated, skin coloured to brown or black coloured, slightly elevated papules or plaques. Facial involvement is often associated with cosmetic concerns in patients. Aims and Objectives: The aim of this study was to compare the efficacy and safety profile of RF ablation with 90% TCA for the treatment of facial SK. Materials & Methods: A total of 80 cases of facial seborrheic keratosis were included in the study. Group A included SK lesions treated with 90% TCA while Group B included SK lesions treated with RF ablation. Patient satisfaction was measured at three months following the completion of the treatment using a four-point scale. Results: In group A, 19 patients (47.5%) were completely satisfied, while in group B, 26 patients (65%) were completely satisfied. Thus, patient satisfaction rate was much higher in group B, however, statistically insignificant.
