O. Kocabalkan et al., REPEATED MANDIBULAR LENGTHENING IN COLLINS,TREACHER SYNDROME - A CASE-REPORT, International journal of oral and maxillofacial surgery, 24(6), 1995, pp. 406-408
A patient with mandibular hypoplasia associated with Treacher Collins
syndrome was treated by bilateral distraction osteogenesis. Since less
than optimal length was provided by the first distraction, a second c
orticotomy was performed in the newly formed bone 6 months after the f
irst distraction. Thus, bone gained by distraction osteogenesis was su
bjected to distraction once again. New bone formation occurred after t
he second lengthening. This case illustrates that distraction osteogen
esis may be applied to the mandible at the site of previous distractio
n.
