[Distraction osteogenesis. A new development in craniofacial surgery].
By means of distraction osteogenesis (callus distraction) it is possible to reshape bone by creating stress across an iatrogenic fracture line. Subsequent to the successful use of this method in orthopaedic surgery, the development of small intra-oral distractors has opened up the possibilities for its application in maxillo-facial surgery, and the correction of orthodontic and dental problems. Following corticotomy and the fixing of the distractor, it is usually possible to begin adjustment on the fifth post-operative day. Adjustment of the distractor twice a day results in a daily distraction of 1 mm. Both congenital and acquired deformities can be corrected in this way. Class II-1 malocclusion can be corrected by simultaneous bilateral distraction. It is concluded that distraction would seem to have a place in maxillo-facial surgery.
