Summary
LeFort III osteotomy for mid-face retrusion in craniofacial dysostoses shows osteodistraction is best for severe cases. Traditional surgery suits adults needing moderate advancements.
Area of Science:
- Craniofacial Surgery
- Orthognathic Surgery
- Pediatric Plastic Surgery
Background:
- Mid-facial retrusion is common in craniofacial dysostoses like Crouzon and Apert syndromes.
- LeFort III osteotomy, first reported in 1951, corrects mid-facial retrusion.
- Osteodistraction offers gradual advancement of the mid-face.
Purpose of the Study:
- To compare traditional LeFort III osteotomy with osteodistraction for mid-face retrusion.
- Evaluate surgical outcomes in 15 craniofacial dysostosis patients (1990-2005).
- Analyze international literature on these techniques.
Main Methods:
- Retrospective clinical outcome study.
- Compared 5 traditional osteotomies with 10 osteodistractions.
- Preoperative assessment included photography, cephalometry, dental models, X-rays, and CT scans.
Main Results:
- Osteodistraction is the preferred treatment for severe mid-face retrusion.
- Traditional LeFort III osteotomy remains suitable for moderate advancements in adults.
- Both techniques address craniofacial dysostoses effectively.
Conclusions:
- Osteodistraction is superior for severe mid-face retrusion correction.
- Traditional LeFort III osteotomy is a viable option for moderate advancements.
- Surgical technique choice depends on the severity of retrusion and patient age.
