Mandibular distraction osteogenesis as first step in the early treatment of severe dysgnathia in childhood



Mandibular distraction osteogenesis as first step in the early treatment of severe dysgnathia in childhood



Journal of Orofacial Orthopedics 57(1): 46-54



The sole orthodontic treatment of severe dysgnathias in childhood often leads to unsatisfactory results. On the other hand, standard surgical procedures are very difficult and due to their high risks not practicable in early childhood. The distraction osteogenesis enables us to correct hypoplastic mandibles, so that secondary malformations of the midfacial complex can be avoided. During the operation the hypoplastic site of the mandible is osteotomized behind the last visible tooth bud and a bidirectional distractor is inserted. Following the principles of Ilizarov the new callus is lengthened gradually until the required length of the mandible has been achieved. Out of a total sample of 27 patients 3 case reports of young children are presented. The new surgical concept describes new treatment perspectives.
