Reconstruction of a midfacial defect can represent a formidable challenge for the reconstructive surgeon. Attesting to both the variety and the complexity of midfacial defects, numerous different classification schemes have been proposed, and are reviewed in this article. The approach to reconstruction can be simplified, however, by classifying maxillectomy defects into four types. Understanding the complex three-dimensional anatomy of the maxilla and its relationship to contiguous structures is the first step in approaching reconstruction of the midface. Achieving basic functional and aesthetic goals of maxillary reconstruction can be achieved using free flap reconstruction with good reliability and predictability in the majority of patients. A specific approach to each defect type is outlined.
面中部缺损的重建对于修复外科医生来说是一个巨大的挑战。面中部缺损的种类繁多，情况复杂，为此提出了许多不同的分类方案，本文对此进行了综述。然而，通过将上颌骨切除术缺损分为四种类型，重建方法可以得到简化。理解上颌骨的复杂三维解剖结构及其与毗邻结构的关系是进行面中部重建的第一步。在大多数患者中，使用游离皮瓣重建可以可靠且可预测地实现上颌骨重建的基本功能和美学目标。本文概述了每种缺损类型的具体处理方法。
