Dorsal reduction (humpectomy) is a simple maneuver in principle, yet it commonly results in irregularities and general inaccuracies, along with occasional internal valve compromise. Traditionally, spreader grafts have been applied to reconstruct an internal valve disrupted during dorsal reduction. Imbricating the dissected ends of the upper lateral cartilages at their interface with the septum (spreader flaps) allows the surgeon to use this tissue, which would otherwise be discarded, to reconstruct the internal valve and design an aesthetically pleasing nasal line. The application of a spreader flap is not only an easily reproducible technique to restore middle vault structure but allows for precise incremental control when performed at the time of humpectomy. To that end, the authors provide a detailed description of their internal valve reconstruction technique, which has been honed over the past 15 years.
背侧缩减（驼峰截除术）从理论上讲是一个简单的操作，但通常会导致不规则和不准确，偶尔还会对内鼻阀造成损害。传统上，在背侧缩减过程中，会使用鼻中隔撑开移植物来重建被破坏的内鼻阀。将上外侧软骨的分离端在其与鼻中隔的交界处进行交错（撑开皮瓣），可以让外科医生使用这些原本会被丢弃的组织来重建内鼻阀并设计出美观的鼻线。撑开皮瓣的应用不仅是一种可重复的技术，可以恢复中隔穹窿结构，而且在进行驼峰截除术时，可以进行精确的增量控制。为此，作者详细描述了他们过去 15 年来完善的内鼻阀重建技术。
