摘要
目的比较波长1 064和532 nm调Q Nd∶YAG激光治疗雀斑的临床疗效、不良反应和复发率。方法雀斑患者80例,一侧面部应用波长532nm、光斑直径2~3 mm对皮损治疗1~2次;对侧面部应用1 064 nm波长、光斑直径6~8 mm平扫皮肤治疗8次。结果波长1 064 nm治疗组,治愈70例,显效8例,好转1例,无效1例,总有效率达98.8%。波长532 nm组,治愈68例,显效10例,好转2例,无效0例,总有效率达100.0%。两种波长治愈率和总有效率比较,差异无显著意义（P〉0.05）。1 064 nm组10例（12.5%）出现不良反应,3例（3.75%）复发;532 nm组80例（100.0%）有不良反应,24例（30.0%）复发。两组治疗后不良反应和复发率比较,差异有显著意义（P〈0.05）。结论调Q Nd∶YAG激光1 064和532 nm波长治疗雀斑均有效,但前者不良反应更少,复发率低。
Objective To compare the clinical and adverse effects of 1 064 nm and 532 nm Q-Switched Nd：YAG lasers in treating Freckles.Methods Altogether 80 patients with freckles were treated with 532 nm Q-Switched Nd：YAG laser（spot diameter for point irradiation：2-3 mm） on one side of the face and 1 064 nm（spot diameter for skin scanning： 6-8 mm） on the other side.Results While the total effective rate of 1 064 nm Q-Switched Nd：YAG laser being 98.8%（70 cases fully cured,8 effectively cured,1 improved and 1 unchanged）,that of 532 nm Q-Switched Nd：YAG laser stands at 100.0%（60 cases fully cured,10 effectively cured,2 improved and 0 unchanged）.As to curative rate and total effective rate,there are not significant differences（P0.05） between them.However,the differences in occurrence rates（1 064 nm laser： 12.5%; 532 nm laser： 100.0%） of adverse effect and recurrence rates（1 064 nm laser： 3.75%; 532 nm laser： 30.0%） were statistically significant.Conclusions Both 1 064 nm and 532 nm Q-Switched Nd：YAG lasers are effective in treating freckles while the former being foundwith less adverse effects and lower recurrence rate.1 064 nm Q-Switched Nd：YAG laser is more acceptable to patients with freckles as no scab forms after the treatment,making daily clean-up possible such as face-washing and bath-taking.
