[Approach to the pterygomaxillary region by the Lefort I osteotomy].
Approach to the pterygomaxillary fossa under the base of skull, a difficult operation, has been facilitated by the use of a technique derived from the Lefort I osteotomy. Satisfactory access to the fossa and to the posterior-base region is obtained and esthetic or functional sequelae avoided.
