Benign neoplasms of the maxillo-facial region require different treatment than do malignant lesions. Conservation of adjacent tissues is vital in order to optimize postoperative function and esthetics. The Le Fort I down-fracture technique is a historically proven approach for resecting benign neoplasms involving the nasal and para-nasal cavities. The Le Fort I, as practised today, is transoral and placed superior to the dento-alveolar processes of the maxilla. Surgical access, therefore, need not result in a skin scar nor loss of dental structures. Postoperative recovery to full function is rapid. The elegance and versatility of the Le Fort I down-fracture technique is discussed with reference to the report of a large, intra-antral benign odontogenic neoplasm.
颌面部良性肿瘤需要与恶性病变不同的治疗方法。保留相邻组织对于优化术后功能和美观至关重要。勒福 I 型低位骨折技术是一种历史证明的用于切除累及鼻腔和鼻窦良性肿瘤的方法。如今实施的勒福 I 型手术是经口进行的,位于上颌牙槽突上方。因此,手术入路无需导致皮肤瘢痕或牙体结构丧失。术后恢复到完全功能状态很快。参照一例大型窦内良性牙源性肿瘤的报告,讨论了勒福 I 型低位骨折技术的优点和通用性。
