Reconstruction of the nasal ala presents surgical challenges, including loss of the nasofacial junction and vasculature compromise, in addition to achieving a cosmetically satisfactory result. The reconstructive surgeon has a variety of closure techniques to employ, but few allow for acceptable cosmesis in a single-stage procedure. The objective of this study is to discuss a novel approach to alar reconstruction using a melolabial-based transposition island pedicle flap, an alternative to traditional interpolated melolabial flaps and inferiorly based interpolated paranasal flap methods. Our reconstruction method utilizes an island pedicle flap harvested from the nasolabial fold and rotated 165˚ medially and superiorly into a surgical defect on the adjacent ala. The pedicle is placed within the alar facial sulcus for a slight trap-dooring effect, recreating the sulcus. The harvest site is closed linearly, resulting in a fusiform scar line to take advantage of the nasolabial fold. Although delicate care is required while dissecting and positioning the flap, it is an otherwise straightforward procedure. The ideal candidate for this technique presents with loss of the alar subunit with an intact alar rim. The only limitation to this style of flap is that the patient has undergone prior procedures involving the ipsilateral nasolabial fold. The transposition island pedicle flap is a well-tolerated alternative to patient cases that require grafting or more involved multi-step reconstructions to efficiently repair nasal alar defects. This technique provides the patient with a presentable cosmetic result using local tissue with minimal post-surgical complications and alar compromise.
鼻翼重建面临着手术挑战,包括鼻面部交界处的缺失和血管受损,此外还要达到美观满意的效果。重建外科医生有多种闭合技术可供采用,但很少有技术能在一期手术中实现可接受的美容效果。本研究的目的是讨论一种使用基于鼻唇沟的转位岛状蒂皮瓣进行鼻翼重建的新方法,这是传统插入式鼻唇沟皮瓣和鼻旁下蒂插入式皮瓣方法的替代方案。我们的重建方法利用从鼻唇沟采集的岛状蒂皮瓣,将其向内侧和上方旋转165˚,转移至相邻鼻翼的手术缺损处。蒂部置于鼻翼面部沟内,产生轻微的活板门效应,重建该沟。供区线性闭合,形成梭形瘢痕线,以利用鼻唇沟。虽然在解剖和定位皮瓣时需要小心谨慎,但该手术在其他方面操作简单。该技术的理想适应证是鼻翼亚单位缺失但鼻翼边缘完整的患者。这种皮瓣的唯一限制是患者同侧鼻唇沟曾接受过手术。对于需要移植或更复杂的多步骤重建以有效修复鼻翼缺损的患者,转位岛状蒂皮瓣是一种耐受性良好的替代方案。该技术利用局部组织为患者提供了美观的效果,术后并发症和鼻翼损伤最小。
