A standard Le Fort I osteotomy was performed on 12 cadavers to determine whether the incidence of pterygoid plate fractures could be reduced by increasing the angle of the curved osteotome relative to the sagittal plane. In the group where an osteotome with the usual angulation was employed, fractures occurred on 9 of 12 sides. In the increased angulation group, 5 of 12 pterygoid plates were fractured. All fractures were restricted to the level of the horizontal osteotomy cut. It is concluded that increased angulation of a curved osteotome can decrease the incidence of fractures of the pterygoid plates. This procedure, however, is not recommended because it can cause fracture of the palatine bone or displacement of the fractured pterygoid plate fragment posteriorly.
对12具尸体进行标准的Le Fort I型截骨术，以确定通过增加弯形骨凿相对于矢状面的角度是否可以降低翼突板骨折的发生率。在使用常规角度骨凿的组中，12侧中有9侧发生骨折。在增加角度组中，12块翼突板中有5块发生骨折。所有骨折均局限于水平截骨切口的层面。结论是，弯形骨凿角度的增加可降低翼突板骨折的发生率。然而，不推荐该方法，因为它可能导致腭骨骨折或骨折的翼突板碎片向后移位。
