Nevus of Ota: Combination Treatment with Q-Switched Neodymium-Doped Yttrium Aluminum Garnet Laser and Fractional CO Laser.

Background: Nevus of Ota is a facial dermal melanocytic hamartoma occurring more commonly in Asians. The mainstay of treatment is 1064-nm Q-Switched neodymium-doped yttrium aluminum garnet (Nd:YAG) laser, which has shown variable results in pigmented skin.

Objective: The aim of this study was to determine whether Q-Switched Nd:YAG laser treatment combined with fractional CO laser is more efficacious than Q-Switched Nd:YAG laser alone.
