[Progressive bone elongation of the maxillo-facial area: mandibular distraction].
Thanks to the distraction osteogenesis technique, it is nowadays possible to create new bone in the facial area. Between january 1997 and march 1999 we have performed 20 such procedures, from which 15 were mandibular. We present our experience in 10 patients with this new technique, 5 unilateral and 5 bilateral. Those were 7 boys and 3 girls, aged 2 to 14 years, affected with hemifacial microsomia, Goldenhar syndrome: 3; retrognatism with severe malocclusion: 4; facial assimetry due temporomandibular joint abnormalities: 2; and facial assimetry: 1. The proposed elongation was achieved in all cases. There was not only a skeletal improvement, but also growth and remodeling of the facial soft tissues. Distraction osteogenesis is the early treatment of the mandibulofacial deformities and offers a great deal of advantages to the growing patient.
