Objective: To observe the clinical effect of Q-switched Alexandrite laser in treatment of hyperpigmentation dermatosis zygomaticus. Methods: 475 cases of hyperpigmentation dermatosis zygomaticus were treated by Q-switched Alexandrite laser. 218 cases of ephelides undertook treatment for 1~2 times,1~3 times for 31 cases of lentigo,1~5 times for 27 cases of café-au-lait-spots and 73 cases of nevus fuscoceruleus zygomaticus,3~8 times for 126 cases of nevus of Ota. The time of interval treatment was 2~3 months for three of the former,4~6 months for two of the latter. Results: The cure rate (effective rate) of ephelides,lentigo,café-au-lait-spots,nevus fuscoceruleus zygomaticus,café-au-lait-spots,and nevus of Ota was 100%,100%,29.62% (62.96%),60.27% (90.41%) and 50.79% (84.12%) respectively. No scarring or pigmentary changes were noted after follow-up 3~36 months. Conclusion: The technique of treatment of hyperpigmentation dermatosis zygomaticus with Q-switched Alexandrite laser is an effect and safe therapeutics with the characteristic of minimal thermal damage to surrounding tissue,shorter period of recovery. It is an ideal therapy for the patients suffering from hyperpigmentation dermatosis zygomaticus.
