目的：探讨耳部瘢痕疙瘩治疗的有效方法。方法自2011年4月~2014年10月对45例患者共56处只耳部瘢痕疙瘩行瘢痕内切除，止血后缝合切口，术后8h内进行6MeV高能电子束（β射线）放射治疗，1次/d，连续照射5次，照射总剂量20~25 Gy。术后随访12~24个月。结果治愈29例(64.4%)，显效10例(22.2%)，无效6例(13.3%)，总有效率86.7%，1例出现感染并伤口延迟愈合(2.2%)。随访未发生其他并发症。结论瘢痕内切除后即时放疗能够有效治疗耳部瘢痕疙瘩。“,”Objective To study the methods of treating auricular keloids.Methods Fourty five patients with a combined total of 56 keloids were treated with 6MeV electron beam radiotherapy after surgical intralesional excision of the keloids.Al received a total dose of 20~25Gy on five consecutive days beginning the day of surgery.The time intervaI between keloid excision and delivery of first fraction of radiotherapy was less than 8h in al case.The median fol ow-up was 12 months.Results 29 cases were noted to have excel ent result and 10 cases were good,total ef ective rate was 86.7%and 6 patients of recur ence was observed during this period,such as delayed wound-healing in 1 patient.No severe complications or secondary malignancies were observed.Conclusion Intralesional excision of keloid and postoperative electron radiotherapy and is wel tolerated and very ef ective in preventing keloid recur ence.
