Repair of soft tissue loss of the medial canthal area is usually accomplished by using skin grafts or frontal flaps based on the glabellar vessels. However, skin grafts can provoke scar tissue contracture, or skin color chromatic changes (hypopigmentation or hyperpigmentation). On the other hand, frontal flaps are sometimes thicker than normal skin and lead to unsatisfactory aesthetic results. To avoid these disadvantages, the authors designed an alternative method for reconstruction of defects of the medical canthal area. The authors suggest using a myocutaneous flap (V-Y design) from the nasal bridge to repair soft tissue defects no larger than 2 cm in diameter (surface < 4 cm2) in the medial canthal area. The pedicle of this flap is based on supratrochlear and dorsal nasal vessels. This technique has proved safe and reliable and has led to good functional and cosmetic results.
内眦区软组织缺损的修复通常采用基于眉间血管的皮片移植或额部皮瓣。然而,皮片移植可引发瘢痕组织挛缩或皮肤颜色变化(色素减退或色素沉着)。另一方面,额部皮瓣有时比正常皮肤厚,导致美学效果不理想。为避免这些缺点,作者设计了一种替代方法用于修复内眦区缺损。作者建议使用来自鼻梁的肌皮瓣(V-Y设计)修复内眦区直径不超过2 cm(面积<4 cm²)的软组织缺损。该皮瓣的蒂基于滑车上血管和鼻背血管。该技术已被证明安全可靠,并取得了良好的功能和美容效果。
