Combined anterior and posterior maxillary osteotomy.

The combined anterior and posterior maxillary osteotomy is primarily indicated for maxillary alveolar hyperplasia. Treatment planning is somewhat more complex than usual for the combined procedure. A method for developing a treatment plan is presented. In contrast to the anterior maxillary osteotomy, the technique for posterior osteotomy is relatively new and has had several recent modifications. Guidelines are presented for rational selection of a specific combined technique. The results obtained with the combined technique have not been well documented. Nonetheless, results appear to be stable and complications are infrequent.
