Fractures of the atrophic, edentulous maxilla during Le Fort I osteotomy.
The incidence of unfavorable fractures of the maxilla during Le Fort I osteotomy was compared between patients with atrophic, edentulous maxillae and patients with normal dentate maxillae. Unfavorable fractures frequently occurred in atrophic, edentulous maxillae. The most common maxillary fracture involved the junction of the horizontal plate of the palatine bone and posterior part of the maxilla. Prevention strategies and treatment options are discussed.
