Mandible plays a pivotal role for both function (mastication, swallowing, and phonation) and aesthetic. Traumas, osteomyelitis, osteoradionecrosis, and benign or malignant neoplasm can cause mandibular defect. Several techniques have been proposed for mandibular reconstruction along the past decades. In this article, we present and discuss a new modified method for accurate mandibular reconstruction. This method is mainly indicated in patients with benign mandibular tumors, where the resection margins can be more often anticipated prior to surgery. However, it is less useful for patients with malignant mandibular tumors, in whom resection margins are often finalized intraoperatively.
下颌骨在功能(咀嚼、吞咽和发声)及美学方面均起着关键作用。创伤、骨髓炎、放射性骨坏死以及良性或恶性肿瘤均可导致下颌骨缺损。在过去几十年间,已提出了多种下颌骨重建技术。在本文中,我们展示并讨论一种用于精确下颌骨重建的新型改良方法。该方法主要适用于良性下颌骨肿瘤患者,这类患者在手术前通常更能预估切除边缘。然而,对于恶性下颌骨肿瘤患者,该方法的作用较小,因为这类患者的切除边缘往往在术中才能确定。
