目的:探讨局部5-氨基酮戊酸光动力学疗法(ALA-PDT)治疗老年疣病的疗效。方法:93例老年疣患者,分别采用局部ALA-PDT治疗63例(A组),二氧化碳(CO2)激光治疗30例(B组)。结果:A组患者经3次治疗后,痊愈16例(25.4%),显效25例(39.7%),有效13例(20.6%),无效9例(14.3%),总有效率65.1%,复发率6.3%,术后伤口疼痛3.2%,无其它明显副作用发生;B组治疗1次,痊愈率100%,复发率16.7%;伤口并发感染7例(23.3%),愈后局部遗留浅表瘢痕9例(30%),伤口疼痛100%。B组复发率、伤口感染率及局部遗留瘢痕的发生率均显著高于A组(P〈0.05)。结论:ALA-PDT无明显痛苦、无瘢痕形成,且复发率低,适合于头面部多发性、较大面积的皮损。 相似文献
