Abstract
Maxillary osteotomy with superior repositioning of the maxilla has proved to be a useful method for correction of open-bite deformity and vertical maxillary excess (”long face” syndrome). However, recognition of the potential risk of this procedure's initiating TMJ disorders must not be neglected. In a study of 13 patients who underwent superior repositioning of the maxilla with a mean of 6 mm, 60% developed TMJ symptoms ranging in severity. A careful preoperative evaluation of each patient is, therefore, recommended.
