The apical triangle is the superior portion of the cutaneous upper lip lying between the medial cheek and alar margin. Defects involving this subunit are often repaired without taking into consideration the aesthetic implications of its potential loss or reduction. We present a simple option for repair of apical triangle defects to address this concern.
We collected a series of 69 patients with apical triangle defects treated from 2002 to 2008 with Mohs micrographic surgery. Their defects were reconstructed using various flaps (advancement, rotation, island pedicle, or M-plasty). A subset of 27 patients was identified who had undergone a standard cheek advancement flap or a modified flap. The modified design introduces an incision extending from the alar crease onto the nasal sill along the cutaneous upper lip, creating a second sliding flap to assist in recreating the apical triangle.
A modified flap design introduced the ability to transfer adjacent tissue of the cutaneous upper lip to reconstruct the apical triangle subunit.
This flap modification is a simple and efficient method of repairing peri-alar defects that restores the apical subunit, preserving facial symmetry.
鼻尖三角区是位于内眦和鼻翼缘之间的上唇皮肤的上部分。涉及这个亚单位的缺陷通常在修复时没有考虑到其潜在的缺失或减少的美学影响。我们提出了一种修复鼻尖三角区缺陷的简单方法来解决这个问题。
我们收集了 2002 年至 2008 年间接受 Mohs 显微外科手术治疗的 69 例鼻尖三角区缺陷患者的资料。他们的缺陷使用各种皮瓣（推进、旋转、岛状皮瓣或 M 成形术）进行修复。我们确定了一组 27 例患者，他们接受了标准的颊推进皮瓣或改良皮瓣的治疗。改良设计引入了一条从鼻翼褶皱延伸到鼻槛上沿上唇皮肤的切口，形成第二个滑动皮瓣，以协助重建鼻尖三角区。
改良皮瓣设计能够转移上唇皮肤的相邻组织来重建鼻尖三角区亚单位。
这种皮瓣改良是修复鼻翼旁缺陷的一种简单有效的方法，它可以重建鼻尖三角区，保持面部对称。
