The nasolabial flap is ideal for reconstruction of the nasal alar subunit due to its proximity, color and contour match, and well-placed donor scar. When raised as a random-pattern flap, there is a risk of vascular compromise to the tip with increased flap length and aggressive flap thinning. Surgical delay can greatly improve the chances of tip survival, allowing the harvest of longer flaps with greater reach.
We describe our technique of lengthening the nasolabial flap through multiple delay procedures. A bipedicled flap was first raised and then transferred as a unipedicled flap with a 6:1 length-to-width ratio. During the delay process, the flap tip was thinned to the subdermal layer.
In our case series of seven patients, defects as far as the medial canthal area and contralateral ala were reconstructed successfully with no incidence of tip necrosis or flap loss. The resultant flaps were thin enough to be folded over for the reconstruction of alar rim defects.
We highlight the success of our surgical technique in creating thin and robust nasolabial flaps for the reconstruction of full-thickness defects around the nose.
鼻唇瓣因位置接近、颜色和轮廓匹配以及供区瘢痕位置合适,是鼻翼亚单位重建的理想选择。当作为随意皮瓣掀起时,随着皮瓣长度增加和过度削薄皮瓣,鼻尖存在血运受损的风险。手术延迟可大大提高鼻尖存活的几率,从而能够获取更长、覆盖范围更大的皮瓣。
我们描述了通过多次延迟手术延长鼻唇瓣的技术。首先掀起双蒂皮瓣,然后将其作为长宽比为6:1的单蒂皮瓣转移。在延迟过程中,将皮瓣尖端削薄至皮下层。
在我们的7例患者病例系列中,成功重建了直至内眦区域和对侧鼻翼的缺损,未发生鼻尖坏死或皮瓣丢失。所得皮瓣足够薄,可折叠用于鼻翼缘缺损的重建。
我们强调了我们的手术技术在创建薄而强健的鼻唇瓣以重建鼻周全层缺损方面的成功。
