title: Surgical correction of vertical maxillary excess: a re-evaluation.
abstract: Correction of vertical maxillary excess by Le Fort I osteotomy has become a widely accepted practice. Although the downfracture method is used almost exclusively in most major centres, the total maxillary alveolar osteotomy still has its advocates. Two patients surgically treated by total maxillary alveolar osteotomy and presented in this journal are re-evaluated with respect to the long-term stability of maxillary intrusion. Literature pertaining to the stability of the maxilla following intrusion by Le Fort I osteotomy and after various combinations of anterior and posterior maxillary ostectomy is reviewed. The advantages of the downfracture method are discussed. An alternative method of achieving the desired degree of intrusion is presented, which ensures more intimate bone contact.
