Nasal reconstruction after severe panfacial burns can be challenging to correct because of scarring, loss of suitable donor sites, and variably limited blood supply of local flaps. We describe 2 cases of subtotal nasal reconstruction in which we overcame these difficulties. Both cases had alar subunit loss, which had left significant functional and esthetic deformities. However, both cases were managed very differently because of availability of donor sites.The first patient had 70% total body surface area burns with bilateral alar subunit loss: nasal reconstruction required a meticulous multistaged forehead flap. The second patient required nasal reconstruction using a turn-down flap to maximize take of a composite graft from previously burned ear donor sites.A number of surgical techniques have been described to manage subtotal burns nasal reconstruction, foremost of which are the nasolabial and paramedian forehead flaps. Cartilage grafts from the septum and the conchal bowl can be integrated into these flaps. Composite grafts can be unpredictable and are often used with caution.Such cases demonstrate that large composite grafts can be an extremely robust method of reconstruction even in a subset of patients with extensively scarred recipient and donor sites. In our second case, composite grafting avoided multistaged procedures such as the forehead flap and can be considered as a first-line procedure in large alar subunit loss.
严重全颜面烧伤后的鼻再造术因瘢痕形成、合适供区缺失以及局部皮瓣血供不同程度受限而难以实施。我们描述了2例次全鼻再造术,在这些病例中我们克服了上述困难。两例均存在鼻翼亚单位缺失,导致了显著的功能和美学畸形。然而,由于供区情况不同,两例的处理方式差异很大。首例患者全身表面积70%烧伤,双侧鼻翼亚单位缺失:鼻再造需要精心设计的多阶段额部皮瓣。第二例患者需要采用翻转皮瓣进行鼻再造,以最大限度地利用先前烧伤的耳部供区获取复合组织移植片。已有多种手术技术用于处理次全烧伤鼻再造,其中最主要的是鼻唇沟皮瓣和正中旁额部皮瓣。鼻中隔和耳甲腔的软骨移植片可整合到这些皮瓣中。复合组织移植片的效果可能难以预测,使用时通常需谨慎。这些病例表明,即使在受区和供区广泛瘢痕化的部分患者中,大型复合组织移植片也是一种极其可靠的再造方法。在我们的第二例病例中,复合组织移植避免了如额部皮瓣等多阶段手术,在大面积鼻翼亚单位缺失时可被视为一线手术方法。
