YAG激光与液氮冷冻治疗耳垂瘢痕疙瘩的比较研究

A comparison between laser and cryotherapy in the treatment of the earlobe scar

目的总结YAG激光治疗耳垂瘢痕疙瘩经验。方法激光组:局部麻醉后用YAG激光依次照射瘢痕基底、中央,直至瘢痕呈白色,中央部位持续时间稍长;冷冻组:同期液氮冷冻治疗。结果激光组:32例(34耳)中治愈1次28例(29耳),2次2例(3耳),3次2例,总治愈率100%。冷冻组:25例(26耳)中治愈1次18例(19耳),2次2例,3次以上5例,总治愈率100%。结论两种方法治疗耳垂瘢痕疙瘩,过程不同,结果基本相同,YAG激光更安全简便,病程稍短。

Objective To summarize the experience for treatment of earlobe scar with YAG-laser. Methods 32 cases（34 ears） were treated by YAG-laser and 25 cases（26 ears） were treated by cryotherapy. Lidocaine was injected into the around of the earlobe scar, and the central and round were radiated with YAG-laser. Result All cases were cured. In the YAG laser group, 29 ears were cured by one treatment, 3 by two treatments and 2 by three treatments. In the cryotherapy group, 19 ears were cured by one treatment, 2 by two treatments and 5 by over three treatments. Condusion The response of the two methods is not significantly different, but YAC-laser is superior to cryotherapy in safety and treatment duration.
