[Surgical approach of a vertical problem: the long face syndrome].

After a clinical review of the "long face syndrome", authors look on surgical therapies: Mandibular osteotomies often relapse because of muscular problems; maxillary surgery is preferred, associated with genioplasties , or else, with anterior and simultaneous mandibular osteotomies. They allow to obtain the desired result. Maxillary surgery has a triple advantage: a new balance for the face the upward and forward antirotation of mandible close the Open Bite the achievement of facial esthetics (alar base width, para-nasal areas and nasolabial angle). Results are shown; they would have been impossible without occlusal, surgical and orthodontic cooperation.
