Saddle nose deformity (SND) is a pathological entity resulting from loss of dorsal height caused by a substantial decrease in the cartilaginous vault or bony vault, and it can occur after a variety of nasal pathological conditions. Most saddle nose deformities are secondary to surgery or trauma, but congenital causes do exist. Repair of saddle nose, therefore, represents one of the most challenging problems in nasal surgery, requiring long-term structural support while avoiding sacrifice of aesthetics. To achieve the desired results, various materials have been employed for nasal contour restoration. The most used grafts are autologous cartilages. Septal cartilage is ideal for reconstruction but often insufficient except in mild cases. Thus, conchal and costal cartilage grafts are the most used in moderate and severe nasal saddling. Augmentation rhinoplasty (AR) is a common procedure in Negroid and Asian patients due to their constitutional lack of dorsal projection. The purpose of this article is to introduce the reverse spare roof technique (rSRT) and its usefulness to correct SND and in AR. To the best of the author's knowledge, this is the first technique that applies the actual principles of preservation rhinoplasty in the correction of the SND and AR.
鞍鼻畸形（SND）是一种由软骨穹窿或骨性穹窿实质性减少导致的背侧高度丧失的病理性实体，可发生于多种鼻部病理状况后。大多数鞍鼻畸形继发于手术或外伤，但也存在先天性原因。因此，鞍鼻修复代表了鼻外科最具挑战性的问题之一，需要长期的结构支撑，同时避免牺牲美学。为了达到理想的效果，已经使用了各种材料来修复鼻轮廓。最常用的移植物是自体软骨。鼻中隔软骨是重建的理想选择，但除了轻度病例外，通常都不够用。因此，在中度和重度的鼻畸形中，最常使用耳软骨和肋软骨移植物。由于黑人及亚洲人先天缺乏背侧突出，因此隆鼻术（AR）在这些人群中很常见。本文的目的是介绍反向备用穹窿技术（rSRT）及其在 SND 和 AR 中的应用。据作者所知，这是第一个将真正的保存性鼻整形原则应用于 SND 和 AR 矫正的技术。
