Rigid fixation and facial asymmetry

Area of Science:

• Craniomaxillofacial surgery
• Orthognathic surgery
• Plastic surgery

Background:

• Facial asymmetry and craniomaxillofacial deformities require precise surgical correction.
• Traditional methods like wire fixation are less precise than rigid fixation.
• Rigid fixation involves screws and plates, demanding meticulous surgical technique.

Purpose of the Study:

• To outline the principles and application of rigid fixation in correcting facial asymmetry.
• To detail the technical considerations for achieving optimal outcomes with rigid fixation.
• To define patient criteria suitable for rigid fixation in craniomaxillofacial reconstruction.

Main Methods:

• Application of rigid fixation principles to osteotomies and bone grafts for facial symmetry.
• Emphasis on passive plate adaptation and accurate screw placement for stable fixation.
• Consideration of patient dentition and bone graft quality for screw fixation suitability.

Main Results:

• Precise techniques with screws and plates lead to improved facial symmetry and occlusion.
• Successful rigid fixation is achievable in patients with erupted permanent dentition.
• Bone graft integrity is crucial for screw retention against muscular forces.

Conclusions:

• Rigid fixation is a precise method for correcting facial asymmetry and craniomaxillofacial deformities.
• Patient selection, particularly dentition and bone graft quality, is critical for successful rigid fixation.
• Meticulous surgical technique ensures optimal functional and aesthetic outcomes in facial reconstruction.
