Current trends in craniofacial distraction: A literature review.

The techniques and procedures involved in craniofacial distraction are constantly evolving. The understanding of histological and biochemical response at the distraction site is now improved. The cascade of events in distraction osteogenesis (DO) differs significantly from the typical fracture healing, and a better knowledge about these events has helped us identify suitable candidates for DO, make appropriate modifications to the distraction protocols and minimize the risk of complications. Recent advances in the manufacturing techniques have also facilitated the availability of distractors of various shapes and designs, which are now changing the way different craniofacial defects are being treated. Small but rigid intraoral distractors now enable easy placement, are well tolerated by patients and allow for a long consolidation period. The introduction of newer approaches toward treatment, together with the simultaneous management of different craniofacial defects at multiple osteotomy sites and enhanced surgical accuracy with the help of digital imaging, have made treatment outcomes more predictable.
