[Distraction osteogenesis as treatment for craniofacial deformities]

Area of Science:

• Plastic and Reconstructive Surgery
• Orthodontics
• Craniofacial Surgery

Background:

• Craniofacial deformities, including those from craniosynostosis, present complex aesthetic and functional challenges.
• Traditional surgical methods may involve significant morbidity and limitations in correction.
• Distraction osteogenesis offers a method for gradual bone lengthening.

Purpose of the Study:

• To evaluate the efficacy of distraction osteogenesis in correcting craniofacial deformities.
• To assess the outcomes of distraction osteogenesis, including aesthetic and functional results.
• To explore the application of endoscopic techniques in distraction osteogenesis.

Main Methods:

• Distraction osteogenesis involves surgical osteotomies of craniofacial bones (frontal, orbits, maxillae).
• Distraction devices are used to achieve controlled, gradual bone advancement.
• Endoscopic techniques can be employed to minimize invasiveness and morbidity.

Main Results:

• The procedure allows for significant anteroposterior bone advancement (16-32 mm frontal, 9-16 mm maxillae).
• Gradual advancement overcomes soft tissue resistance, enabling substantial bone repositioning.
• New bone formation occurs in the distraction gaps, stabilizing the advanced segments.

Conclusions:

• Distraction osteogenesis is a highly effective technique for correcting complex craniofacial deformities.
• The procedure yields satisfactory aesthetic and functional outcomes with reduced morbidity when using endoscopic approaches.
• This method facilitates significant skeletal advancement, improving patient quality of life.
