A large, recurrent basal cell carcinoma involving the left forehead and suprajacent hair-bearing scalp was excised, following which an esthetically acceptable reconstruction of the scalp and hairline margin was accomplished.
A method of utilizing two hair-bearing flaps to cover a large defect at the hair-bearing scalp margin will be photographically demonstrated, and the maneuvers to precisely reconstruct the scalp's anastomotic margin with the forehead will be shown and discussed.
Dual hair-bearing "winged" V-plastic flaps were evolved anteriorly, the two flaps joined, an M-plasty (Webster) was then incorporated to spare hair-bearing scalp posteriorly, and the entire conjoined scalp flap then advanced anteriorly to the forehead. The precise curvatures of the anastomotic line were reestablished by exact excisions of forehead skin underlying the hair-bearing scalp flaps, or amputations of overlying hair-bearing scalp in excess of forehead needs.
An esthetically pleasing and reasonably exact reconstruction of the hair-bearing scalp and forehead anastomotic line was accomplished.
A precise reconstruction of the forehead/scalp margin can be accomplished utilizing a combination of techniques, including hair-bearing "winged" V-plastic flaps, an M-plasty, and the serial removal of segments of both glabrous and nonglabrous skin to reestablish the frontal hairline margin.
切除了一个累及左前额及上方有毛发头皮的复发性基底细胞癌大病灶,随后完成了在美学上可接受的头皮及发际线边缘重建。
将通过照片展示一种利用两个有毛发皮瓣覆盖有毛发头皮边缘大缺损的方法,并展示和讨论精确重建头皮与前额吻合边缘的操作。
向前设计两个带毛发的“翼状”V形皮瓣,将两个皮瓣连接起来,然后采用M成形术(韦伯斯特法)以保留后方的有毛发头皮,接着将整个联合头皮皮瓣向前推进至前额。通过精确切除有毛发头皮瓣下方的前额皮肤,或切除覆盖在前额上方多余的有毛发头皮,重新建立吻合线的精确曲率。
实现了在美学上令人满意且相当精确的有毛发头皮及前额吻合线重建。
利用包括带毛发的“翼状”V形皮瓣、M成形术以及连续切除无毛和有毛皮肤片段以重建额部发际线边缘等多种技术的组合,可精确重建前额/头皮边缘。
