摘要 目的比较755 nm半导体激光在耳廓再造术不同时期脱毛的临床有效性及患者满意度。方法2016年7月至2018年9月,应用755 nm半导体激光对86例在华中科技大学同济医学院附属同济医院整形外科行耳廓再造术的患者进行脱毛,男39例,女47例,年龄6~28岁,平均12岁,左耳28例,右耳58例。简单随机分组,40例于一期耳后皮肤扩张器置入术后行耳廓脱毛(一期术后脱毛组),46例于二期耳廓重建术后脱毛(二期术后脱毛组)。分别于不同干预时间下行耳廓脱毛治疗,脉宽10~20 ms,波长755 nm,光斑直径10 mm×15 mm,能量密度4~8 J/cm2。每次脱毛时间均为5~10 min,以局部皮肤毛乳头出现轻微发红或水肿为治疗终点。每隔4周左右做1次激光脱毛治疗,共5次。计数不良反应例数,比较治疗前及第5次脱毛后6个月的毛发生长密度、毛发清除率及患者满意度。结果2组患者均顺利完成治疗,随访至最后一次脱毛治疗后6个月左右(23~25周),仅二期术后脱毛组有2例备皮时划伤,2例出现水泡,其余患者均无不良反应发生。一期术后脱毛组治疗后毛发密度为(27.63±7.75)根/cm2,少于治疗前的(84.55±13.68)根/cm2;二期术后脱毛组治疗后毛发密度为(40.52±5.92)根/cm2,少于治疗前的(74.78±11.19)根/cm2,差异均具有统计学意义(P值均<0.001)。激光脱毛后,一期术后脱毛组毛发密度低于二期术后脱毛组,差异具有统计学意义(P<0.001)。一期术后脱毛组毛发清除率为67.32%,高于二期术后脱毛组的45.81%,差异具有统计学意义(P<0.001)。一期术后脱毛组患者满意度为87.5%(35/40),二期术后脱毛组为69.5%(32/46),前者高于后者。结论一期扩张器置入术后开始行755 nm半导体激光耳廓脱毛的临床疗效更好,患者满意度更高。 Objective To compare the clinical efficacy and patient satisfaction of 755 nm semiconductor laser for hair removal during different stages of auricular reconstruction.Methods From July 2016 to September 2018,86 patients who had ear reconstruction underwent 755 nm semiconductor laser for auricle hair removal in plastic surgery department of Tongji hospital affiliated to Tongji medical college of Huazhong university of science and technology.There were 39 males and 47 females with an average age 12 years old(from 6 to 28 years old).28 cases were left ear,58 cases were right ear.With random grouping,40 patients underwent auricle hair removal treatment after posterior ear tissue expander implantation(post-operation of stageⅠdepilation group)and 46 patients underwent treatment after auricular reconstruction(post-operation of stageⅡdepilation group).Auricle hair removal treatments(pulse width 10-20 ms,wave length 755 nm,spot size 10 mm×15 mm,energy density 4-8 J/cm2)were respectively started at different intervention time.Each treatment time were 5-10 minutes.The end of the treatment was slight redness or edema of the local hairy follicle.The treatment was repeated every 4 weeks with a total of 5 times.The number of adverse reactions was recorded as while as the hair density,hair clearance rate and patient satisfaction before treatment and 6 months after the 5th depilation.Results Patients in both groups successfully were completed the treatment and were followed up to about 6 months(23 to 25 weeks)after the last depilation treatment.There were only 2 cases with scratch in skin preparation and 2 cases with blisters in the postoperative of stageⅡgroup.None of the other patients had adverse reactions.Hair density after treatment(27.63±7.75 bar/cm2)was less than before treatment(84.55±13.68 bar/cm2)in post-operation of stageⅠdepilation group.Hair density after treatment was 40.52±5.92 bar/cm2 in post-operation of stageⅡdepilation group,less than before treatment(74.78±11.19 bar/cm2).The differences were sta
