Treatment of nevus of OTA by Q-switched, frequency doubled, ND:YAG laser.

Nevus of Ota is a dermal melanocytic nevus for which hitherto no effective therapy was available. Lasers have been successfully tried for ablation. But there is no Indian experience till date. Q-Switched, Frequency Doubled, Nd:YAG Laser was installed at our centre an year ago. The first operated case, which has shown near complete pigment dilution, is being presented. The patient underwent three treatments with a minimum of 2 months between sessions. Pre and post therapy photographs were taken and side effects documented. The patient has shown near complete pigment dilution after 3 treatments. Q-Switched, Frequency Doubled, Nd:YAG Laser is effective in treating Nevus of Ota in the Indian skin types. There are no complications noticed till date in our experience.
