【摘要】 本研究对比Q开关翠绿宝石755 nm激光和Q开关Nd:YAG1 064 nm激光治疗太田痣的疗效和差别,探讨分析原因。分别用Q开关翠绿宝石755 nm激光和Q开关Nd:YAG1 064 nm激光治疗637例太田痣患者,观察患者治疗前后疗效,根据色素减轻百分比进行评定。结果表明Q开关翠绿宝石755 nm激光和Q开关Nd:YAG1 064 nm激光均能安全有效的治疗太田痣,Q开关翠绿宝石755 nm激光治疗太田痣297例,显效率为83.5%,Q开关Nd:YAG1 064 nm激光治疗太田痣340例,显效率为86.76%,显效率没有统计学差异。但Q开关翠绿宝石755 nm激光对褐色太田痣疗效较高:755 nm组褐色显效率为91.62%;1 064 nm组显效率为77.84%,统计学差异有显著性,而Q开关Nd:YAG1 064 nm激光对蓝色太田痣疗效较高:755 nm组蓝色显效率为80.54%;1 064 nm组显效率为92.86%,统计学差异有显著性,且1 064 nm组术后发生色素沉着较755 nm组少更多还原

【Abstract】 To compare the Q-switch 755 nm and Q-switch 1064 nm laser treatment of nevus of Ota’s efficacy and differences,and Investigate the reasons.Using Q-switch 755 nm and Q-switch 1064 nm laser to give treatment to 637 cases of nevus of Ota.Observe the efficacy of each patient before and after the treatment,Evaluate the effect by the percentage of the pigment subsided.The results showed that Q-switch 755 nm and Q-switch 1064 nm laser can both cure nevus of Ota safely and effectively.Q-switch755 nm laser was used to treat 297 cases of nevus of Ota,the effective rate is 83.5%.Q-switch 1064 nm laser was used to treat 340 cases of nevus of Ota,the effective rate is 86.76%,there is no statistically significant difference in efficiency.However,755 nm laser Q-switch effect on brown nevus of Ota is better than 1 064 nm Q-switch laser:755 nm group effective rate is 91.62%;1064 nm group is 77.84%,x~2=13.89,P<0.001,there is a significant difference,and the 1064 nm Q-switch laser effect on the blue nevus of Ota is better than 755 nm laser Q-switch;755 nm group effective rate is 80.54%;1064 nm group is 92.86%,there is a significant difference.And the 1064 nm group postoperative pigmentation occur less than the 755 nm group.更多还原
