Objective:To observe the q-switched Nd;The curative effect of YAG laser treatment of facial brown blue nevus and adverse reactions. Method:The q-switched Nd;YAG laser therapy unit to treat facial brown blue nevus,70 cases of patients,with a wavelength of 1064 nm,the energy density of 400~800 MJ/cm2,spot diameter 3 mm,1~5 hz frequency,treatment of 2~6,3~6 months follow-up after judging curative effect and adverse reactions. Results:In 70 patients after 2~6 treatments,time interval for three to six months,a total cure 27 cases(38.6%),the total effective rate was 100%. The curative effect is proportional to the number of treatment. Conclusion:The Q switch Nd;YAG laser treatment of facial brown blue nevus curative effect,except some temporary pigmentation occurred in patients with no other adverse reactions and complications.
