ABSTRACT
Introduction:
Seborrheic keratosis (SK) are benign lesions with cosmetic concerns. Role of TCA and erbium YAG laser has already been described individually in the literature. However, there is a scarcity of data on the comparative evaluation of these two modalities in SK.Aim:
The aim of this study was to compare the efficacy and safety profile of Erbium YAG laser ablation with 70% TCA for the treatment of facial SK. Materials andMethods:
A total of 50 cases of facial SK were included in the study. Group A included SK lesions on the right side of face treated with Erbium YAG laser ablation while Group B included SK lesions on the left side of face treated with topical 70% trichloroacetic acid. Repeated sessions of laser and TCA application were given at 2-week intervals till cure was achieved or up to a maximum of three sessions. Grading of response to treatment was assessed as complete response (100% clearance), partial response (>50 to 99% improvement), and inadequate or no response (<50% improvement).Results:
Complete clearance was observed in 40 (80%) and 29 (58%) cases in Groups A and B, respectively. There was a statistically significant difference in clearance rates between the two groups (P = 0.019). Number of sessions was significantly lesser in laser group (mean ± SD = 1.24 ± 0.43) than in the 70% TCA group (mean ± SD = 1.88 ± 0.79) (P = 0.001). Statistically significant lesser downtime was observed in group A (P = 0.001). Patient satisfaction rate was much higher in group A. Hyperpigmentation was more common in group B (TCA).Conclusion:
Although both the treatment modalities achieved good results, erbium YAG laser ablation showed superior results than 70% TCA with better patient satisfaction rates but more downtime. Also, no major adverse effects were observed in the two groups.
