Distraction osteogenesis of the craniofacial skeleton

Area of Science:

• Craniofacial Surgery
• Orthopedic Surgery
• Regenerative Medicine

Background:

• Distraction osteogenesis (DO) techniques, initially for limb lengthening, are now successfully applied to craniofacial bones.
• DO offers stable bone regeneration with potentially lower relapse rates compared to conventional osteotomy and bone grafting.

Purpose of the Study:

• To evaluate the efficacy and applications of distraction osteogenesis in craniofacial bone lengthening.
• To compare DO with traditional surgical methods for craniofacial deformities.

Main Methods:

• Review of clinical experience with distraction osteogenesis for mandible and midface lengthening.
• Analysis of bone regenerate quality, relapse rates, and soft-tissue elongation.
• Consideration of protocols, devices, and distraction parameters.

Main Results:

• DO is a safe and effective treatment for mandible lengthening (10-year experience) and midface advancement (5-year experience).
• DO provides high-quality bone regeneration, reduced long-term relapse, and simultaneous soft-tissue elongation.
• DO is particularly useful for severe craniofacial deformities in children, including those with developmental hypoplasia and syndromic craniosynostosis.

Conclusions:

• Distraction osteogenesis is a viable and advantageous treatment option for craniofacial bone lengthening.
• Challenges remain in predicting growth compensation in pediatric patients, potentially requiring future surgical interventions.
• DO offers significant benefits over conventional bone grafting and fixation techniques in craniofacial reconstruction.
