Rigid fixation and osteotomy design in frontal orbital advancement osteotomies

Area of Science:

• Craniofacial Surgery
• Orthognathic Surgery
• Pediatric Plastic Surgery

Background:

• Major craniofacial deformities often require extensive surgical correction.
• Relapse, particularly at the maxillary level, is a concern in early interventions due to inadequate dental occlusion.
• Rigid fixation methods are crucial for maintaining segment position after mobilization.

Purpose of the Study:

• To evaluate the efficacy of extensive corrective osteotomies with rigid fixation for major craniofacial deformities.
• To demonstrate the advantages of one-stage reconstruction in pediatric patients with Crouzon's disease and Apert's syndrome.
• To highlight the long-term stability achieved through advanced fixation techniques.

Main Methods:

• Performed one-stage reconstructions involving multiple osteotomies and extensive mobilization of the craniofacial complex (forehead, orbits, maxillae).
• Utilized rigid fixation methods, including anchor wire osteosynthesis and metal plates, adapted for Crouzon's disease and Apert's syndrome.
• Employed modified monoblock advancements and facial bipartition concepts for three-dimensional correction, including midfacial vertical elongation.

Main Results:

• Successful long-lasting corrections were achieved in sixteen pediatric patients.
• The applied rigid fixation methods effectively preserved the position of mobilized craniofacial segments.
• The one-stage reconstruction approach proved efficacious for complex craniofacial deformities.

Conclusions:

• Extensive corrective osteotomies with rigid fixation provide superior outcomes for major craniofacial deformities compared to partial corrections.
• This surgical approach ensures stable, long-lasting results in pediatric patients with syndromic craniosynostosis.
• Advanced fixation techniques are essential for preventing relapse and achieving successful three-dimensional facial reconstruction.
