选择性单株毛发植入在眉毛部分缺损修复中的应用

目的探讨在眉毛缺损修复手术中选择性应用不同直径单根毛发植入的临床效果。方法49例眉毛缺损患者，其中先天性眉毛稀疏37例，外伤后引起的瘢痕性眉缺损12例。在局部麻醉下从枕部靠近后发际线和耳后发际线内获取单体毛囊，粗细毛发分开摆放，应用22G或23G注射针头按正常眉毛方向打孔后将单根毛发植入。在眉头、眉尾和眉毛上缘应用较细的头发，眉中央用较粗的头发。结果术后随访3～10个月，植入的眉毛生长良好，需要5～7d左右修剪1次。两侧眉毛对称。12例患者因移植的眉毛有局部成活不良，在术后6～12个月进行二次手术补植加密。所有患者对术后效果表示满意。结论选择性植入不同直径单根毛发的眉毛缺损修复术，能再造出外观自然、形态逼真的眉毛，效果良好。

Application of transplanting different diameter single hair in treatment of part eyebrow defect

Objective To explore the effects of implanting different diameter single hair in treat- ment of part eyebrow defect. Methods 49 patients with part eyebrow defect, including 37 congenital sparse eyebrows and 12 traumatic eyebrow detect, were performed hair transplantation. Single-hair grafts were harvested from the scalp behind ear or the inferior part of the oeeiput. Single-hair grafts were implanted according to directions of normal eyebrow. 22G or 23G needle was used for stick-and- place insertion. The thick and thin hairs were divided. The thin hairs were implanted into the medial and distal ends and the upper edge, the thick hairs were implanted into the center. Results After 3-10 months follow-up. The reconstructed eyebrows growed slowly, about every 5-7 days nee- ded be trimmed. Two sides eyebrows were symmetry. Because a small amount of transplanted hairs were not alive, twelve patients were performed the second operation for thicker eyebrow. All patients were satisfied with the results. Conclusions In treatment of part eyebrow defect, the results of im- planting different diameter single hair are natural and vivid.
