目的 分析超脉冲CO2激光手术对耳郭脂溢性角化病(SK)的治疗效果.方法 回顾性病例研究.收集16例经超脉冲CO2激光手术切除、术后病理确诊的耳郭SK患者,分析病损部位、创面面积、皮肤愈合时间、愈合效果等临床资料.结果 病损部位:耳甲艇6例、耳甲腔5例、三角窝2例、舟状窝2例、对耳轮1例.病损面积最大2.1 cm2,最小0.09 cm2,平均(1.41 ±0.45) cm2.创面皮肤愈合良好,与周围正常组织之间无明显界限,也未见瘢痕组织.结论 CO2激光治疗耳郭SK能实现创面自然愈合,避免瘢痕形成,疗效良好.%Objective To analyze the therapeutic efficacy of superpulsed CO2 laser for seborrheic keratosis (SK) in the auricle.Methods A retrospective study was performed in sixteen patients presenting with SK in the auricle.All patients were confirmed by pathology after a complete superpulsed CO2 laser excision.The wound position,wound area,healing time were recorded,granulation tissue growth and epithelization in wound were observed,and wound healing status was evaluated.Results SK occurred mostly on the cymba conchae (6 patients),followed by the cavum conchae (5 patients),triangular fossa (2 patients),navicular fossa (2 patients) and antihelix (1 patient).The wound areas vary from 0.09 cm2 to 2.1 cm2,with average wound area being (1.41 ± 0.45) cm2.The skin wounds of all patients healed well.There was no obvious boundary between wound area and the surrounding tissues and no scar was seen in all patients.Conclusions Superpulsed CO2 laser surgery for in the auricle could achieve spontaneous healing and prevent the formation of scar.The efficacy is good.
