目的:探讨连续扩张器置入法在修复儿童大面积瘢痕性秃发中的临床效果。方法:2015年2月至2019年10月，昆明医科大学附属儿童医院烧(创)伤整形外科共收治大面积瘢痕性秃发患儿5例，年龄3～14岁，其中男3例，女2例，秃发面积超过1/2头皮。其中枕部巨大皮内痣切除植皮术后瘢痕秃发1例，烧伤后瘢痕秃发4例。均采用连续扩张器置入法连续扩张头皮。一期：扩张器置入，扩张正常皮肤软组织；二期：取出扩张器，切除部分瘢痕后转移扩张皮瓣修复创面，皮瓣下方接力置入扩张器，继续进行扩张；三期：扩张器取出，切除残余瘢痕秃发区，滑动推进或旋转扩张皮瓣修复遗留秃发区。观察术后效果。结果:5例患儿中2例残余10 cm ×4 cm、6 cm ×2 cm秃发部位，其余3例秃发得到完全修复，其完全修复患儿中1例切口瘢痕较宽。随访3个月至3年，患儿均毛发生长茂盛，走行接近正常，效果满意。结论:应用连续扩张器置入修复儿童大面积瘢痕性秃发术后效果好、疗程短、费用低、可行性高。“,”Objective:To investigate the clinical outcome of continuous expander implantation in the repair of large cicatricial alopecia in children.Methods:From February 2015 to October 2019, 5 cases of large cicatricial alopecia were treated, aged from 3 to 14, including two boys and two girls. The area of alopecia exceed 1/2 of scalp. One case is intradermal nevus excision. Four cases were scar after burn. All cases were used continuous expander implantation to expand scalp. In the first stage, the expander was implanted and the normal skin was expanded. In the second stage, the expander was removed. After the cicatrix was cut partly, the expanded skin flap was transferred to repair the wound and the expander was placed under the expanded skin flap in a relay way. Then the expansion was continued. In the third stage, the expander was removed, the residual cicatricial alopecia was cut and reconstructed by the expanded flap. Advanced flap and rotational flap were applied and the efficacy was observed.Results:Among the 5 children, 2 cases were left with 10 cm×4 cm alopecia and 6 cm×2 cm alopecia. The other 3 cases were completely restored. The incision scar was wider in one case. The follow-up period was from 3 months to 3 years. Hair grows well and the shape of the hair was close to normal. The results were satisfactory.Conclusions:Continuous expander implantation in the repairation of large cicatricial alopecia in children have many advantages, including good postoperative results, short course, low cost and highly feasible.
