Achieving a natural appearing dorsum in secondary rhinoplasty remains an elusive goal. An inherent contradiction exists between the two most usually used techniques: solid rib segment and diced cartilage fascia constructs. The former will often cause edge visibility, in addition to potential warping and distortion; the latter prevents from both but may generate obtuse, ill-defined borders with poor shape control, possible contour asymmetries, and often a tubular appearance. A solution to the equation can be found in an innovative technique that combines three elements: perichondrium, rectus fascia, and a rib lamination. The combination is called the sandwich of perichondrium and fascia (SPF) or the sandwich of perichondrium, rib lamination, and fascia (SPLF). As a single unit over the entire dorsum, the issues of junction irregularity inherent in the use of separate graft segments, and of asymmetries in the dorsal contour because of inadequate distribution of diced cartilage, are avoided. In a greater than 18-month experience on 23 cases at the time of writing, the SPF-SPLF graft has proved to be an ideal solution. Adequate edge definition and elegant related shadowing are provided, precise tailoring is attained, and proper height of the dorsum contour is reestablished, following adequate reconstruction of the underlying dorsal plateau. The gradual flow from SPF to SPLF is logical and progressive according to need, and proper fixation ensures long-term stability of the hybrid construct. All three elements required are harvested from the same donor site with a resulting minimal scar.
在二次鼻整形术中,实现自然的背部外观仍然是一个难以实现的目标。两种最常用的技术之间存在固有矛盾:实心肋段和切丁软骨筋膜构建体。前者通常会导致边缘可见,此外还可能发生扭曲和变形;后者可以防止这两种情况发生,但可能会产生钝角、不明确的边界,形状控制不佳,可能存在轮廓不对称,并且通常外观呈管状。可以通过一种创新技术找到这个问题的解决方案,该技术结合了三个元素:软骨膜、腹直肌筋膜和肋板层。该组合被称为软骨膜和筋膜三明治(SPF)或软骨膜、肋板层和筋膜三明治(SPLF)。作为整个背部的单一单元,避免了使用单独的移植物段时固有的连接不规则问题,以及由于切丁软骨分布不足导致的背部轮廓不对称问题。在撰写本文时,在超过 23 例的 18 个月以上的经验中,SPF-SPLF 移植物已被证明是一种理想的解决方案。提供了足够的边缘定义和优雅的相关阴影,实现了精确的剪裁,并在充分重建底层背侧平台后,重新建立了背侧轮廓的适当高度。根据需要,从 SPF 到 SPLF 的逐渐过渡是合理和渐进的,适当的固定可确保混合结构的长期稳定性。所有三个所需的元素都从同一供体部位采集,从而产生最小的疤痕。
