Abstract
Objective: To evaluate the effectiveness of treat Ota’s nevus by picosecond laser Nd:YAG 1064nm. Subject and method: A cross-sectional descriptive study of Ota’s nevus was conducted by reviewing the clinical characteristics and photographs of one hundred patients (ages from 2 years to 55 years). The patients were treated in the 108 Military Central Hospital with a picosecond Nd:YAG 1064nm from September 2017 to October 2018 with energy fluence ranged 1.2 - 2.4J/cm² and a spot size of 4 - 5mm, every 4 - 6 weeks. Statistical analysis was used to compare outcomes and determine contributing factors. Result: All patients obtained clinical improvement ranging from good to very good. After 3, 6, 9 sessions of the treatment, improvement on the color of the nevus at very good and good levels were respectively 45%, 67.53% and 86.11%. Conclusion: Our results suggest that 1064nm picosecond laser treatment is efficacious for the treatment of nevus of Ota with minimum adverse side effects.
