Direct closure of large scalp defects is not an easy task. Complicated flap designs or staged surgeries over a period of 6 months are often required. A case of a large scalp defect that was closed directly in 3 months by applying a simple external tissue expansion technique is presented in this report.
A 28-year-old male patient presented with a painful swelling of about 13 cm × 14 cm, on frontoparietal scalp. A biopsy done elsewhere reported it to be a neurofibroma. He sought tumour excision and scalp defect coverage by hair-bearing scalp in a period of less than 5 months.
The tumour was excised and the adjacent scalp was gradually expanded with the help of an external fixator. The patient had immediate pain relief after excision. The goal of repairing scalp defect and replacing it with hairy scalp was achieved in 3 months.
The mechanical device required for this technique is relatively easily accessible. It is not difficult to achieve desirable outcomes, and the same can be applied to large wounds on other areas.
直接闭合大型头皮缺损并非易事。通常需要复杂的皮瓣设计或为期6个月的分期手术。本报告介绍了一例通过应用简单的外部组织扩张技术在3个月内直接闭合大型头皮缺损的病例。
一名28岁男性患者，额顶部头皮出现一个约13厘米×14厘米的疼痛性肿胀。在其他地方进行的活检报告显示为神经纤维瘤。他希望在不到5个月的时间内切除肿瘤并使用有毛发的头皮覆盖头皮缺损。
切除肿瘤，并借助外部固定器逐渐扩张相邻的头皮。患者在切除后立即疼痛缓解。在3个月内实现了修复头皮缺损并用有毛发的头皮替代的目标。
该技术所需的机械设备相对容易获得。实现理想的结果并不困难，并且同样可应用于其他部位的大型伤口。
