- PURPOSE : The purpose of the study is to evaluate the clinical effect of the Q-switched alexandrite laser in the treatment of Ota's nevus and tattoo.
MATERIAL AND METHODS : Ninety-six patients with Ota's nevus and tattoo were treated with a Q-switched alexandrite laser (model TL-1, Candela Laser Corporation. Wayland. U.S.A). The effects were examined by further photographs and telephone follow-up. The response was expressed as the percentage area cleared of the lesion. The clearance was graded as follows: clear, >95% ; excellent, 76-95% ; good, 51-75% ; fair, 26-50% ; poor <25%. The occurrence of adverse events was also examined.
RESULTS : Treatment with energy that ranged from 6.0-10.0J/cm2 was given on average 1.8 times and 89% improvement was seen. No patient had permanent textual changes or scarring.
CONCLUSION : The Q-switched alexandrite laser is an effective treatment for nevus of Ota's and tattoo with a low incidence of significant adverse effects and provides excellent cosmetic results.
