The Le Fort I osteotomy is a versatile operation for correction of developmental, congenital, and posttraumatic deformities of the lower midface. One of the challenges of the osteotomy is pterygomaxillary separation, with the potential for unfavorable fractures to the orbit/skull base or vascular injury. A modified technique for pterygomaxillary disjunction is the transmucosal tuberosity osteotomy. The authors have used this technique for pterygomaxillary separation in 200 consecutive Le Fort I osteotomies over a 3-year period (2014 to 2017). There were no episodes of unfavorable propagation to the skull base or orbit, oroantral or oronasal fistulae, excessive bleeding/vessel injuries, or vascular insufficiency to the maxilla. The transmucosal tuberosity approach is a reliable and safe method of performing the pterygomaxillary separation during the Le Fort I osteotomy.
Le Fort I 上颌骨切开术是一种用于矫正下颌面发育性、先天性和外伤性畸形的多功能手术。该手术的一个挑战是翼上颌分离，可能导致眶/颅底骨折或血管损伤。一种改良的翼上颌分离技术是经黏膜结节截骨术。作者在 3 年期间（2014 年至 2017 年）对 200 例连续 Le Fort I 上颌骨切开术使用了该技术进行翼上颌分离。没有发生不良的颅底或眶部扩展、口鼻瘘、过度出血/血管损伤或上颌血管不足的情况。经黏膜结节入路是一种可靠且安全的方法，可在 Le Fort I 上颌骨切开术中进行翼上颌分离。
