Surgical-orthodontic correction of maxillary retrusion by Le Fort I osteotomy and proplast.
The combined efforts of the orthodontist and surgeon are necessary for successful treatment of most patients with maxillary retrusion. Both the aesthetic and functional manifestations of this dento-facial deformity can usually be effectively treated by maxillary advancement, augmentation of the midfacial region and orthodontics. Treatment planning, pre- and post-surgical orthodontic treatment principles, and surgical considerations in treating 25 adults with maxillary retrusion are described and illustrated. Surgical advancement of the maxilla by Le Fort I osteotomy, proper alignment of the teeth by orthodontics, and augmentation of the paranasal, canine fossae and malar regions with Proplast, were the common denominators of successful treatment.
