[Bone lengthening: application to the mandible. Review of the literature].

In literature, the authors demonstrate that progressive distraction osteogenesis, according to the Ilizarov method, is applicable to the mandible. Mandibular distraction is achievable through external approach or through oral approach. Further experimental and clinical studies will be necessary to define the most stable apparatus and the best indications that are currently hemifacial microsomia and facial asymmetry associated with T.M.J. ankylosis.
