Modified bimaxillary distraction osteogenesis: A technique to correct facial asymmetry

Treatment of severe micrognathia in an adult with distraction osteogenesis: A case report

“…DO is often performed in children, teenagers, and young adults, who have a high ability for osteogenesis. 1 , 12 Although DO in adults has been reported, 4 , 12 , 13 , 14 , 15 , 16 , 17 only two patients were aged >30 years: a 65‐year‐old man with unilateral distraction 16 and a 34‐year‐old man with bilateral mandibular DO using an intraoral tooth‐borne device. 4 The small number of adult cases might be due to the concern regarding whether sufficient bone would be formed by DO, and because DO is usually performed at a younger age, as treatment for micrognathia begins in childhood.…”

A systematic review on the outcome of distraction osteogenesis in TMJ ankylosis

“…Prearthroplastic DO 3,[23][24][25][26][27][28][29][30][31][32][33][34][35] : Pre-arthroplasty distraction is preferred for multiple reasons. It allows distraction against a stable fixed point, such that a true distraction of mandible occurs and that too in the desired direction only, and with a better vector control.…”

“…A comparison of Prearthroplasty and simultaneous distraction showed that although prearthroplasty DO provides better control of the distracting segment, but unlike simultaneous distraction, it bears a disadvantage that the final mandibular position cannot be predicted as the final mandibular position tends to change due to muscle pull after the release of ankylosis. 26,30,34,37,41 An occlusal cant which exceeds 3 in frontal plane is clinically significant. In cases where delay in treatment leads to significant maxillary hypoplasia, mandibular distraction can be coupled with simultaneous maxillary distraction by Lefort 1 osteotomy and fixation at the contralateral zygomaticomaxillary buttress.…”
