目的:探讨重组人表皮生长因子面膜联合Q开关Nd∶YAG激光对雀斑患者皮肤美观度及复发情况的影响。方法:将80例2020年1月-2022年12月重庆三峡医药高等专科学校附属人民医院皮肤科收治的雀斑患者随机纳入对照组(40例)和试验组(40例),分组方法选择随机数字表法。对照组给予Q开关Nd∶YAG激光进行治疗,试验组在对照组的基础上给予重组人表皮生长因子面膜进行治疗,两组均治疗3个月,并随访5个月。比较两组治疗3个月后的疗效,治疗前和治疗3个月后的皮肤特征、皮肤美观度,不良反应,随访期间的复发情况及随访5个月后的满意度。结果:试验组治疗3个月后的总有效率为95.00%,高于对照组的80.00%(P0.05);随访期间的复发率为2.50%,与对照组(5.00%)比较,差异无统计学意义(P>0.05)。试验组随访5个月后的总满意率为95.00%,高于对照组的77.50%(P<0.05)。结论:重组人表皮生长因子面膜联合Q开关Nd∶YAG激光可改善雀斑患者皮肤特征及美观度,进而有利于提高患者疗效及满意度,且并未明显增加患者不良反应及复发风险。
