Long-term Follow-up after Maxillary Distraction Osteogenesis in Growing Children with Cleft Lip and Palate

Objective: To evaluate the changes in maxillary position after maxillary distraction osteogenesis in six growing children with cleft lip and palate. Design: Retrospective, longitudinal study on maxillary changes at A point, anterior nasal spine, posterior nasal spine, central incisor, and first mola...

Description
Summary:Objective: To evaluate the changes in maxillary position after maxillary distraction osteogenesis in six growing children with cleft lip and palate. Design: Retrospective, longitudinal study on maxillary changes at A point, anterior nasal spine, posterior nasal spine, central incisor, and first molar. Setting: The University Hospital Craniofacial Center. Main Outcome Measure: Cephalometric radiographs were used to measure the maxillary position immediately after distraction, at 6 months, and more than 1 year after distraction. Results: After maxillary distraction with a rigid external distraction device, the maxilla (A point) on average moved forward 9.7 mm and downward 3.5 mm immediately after distraction, moved backward 0.9 mm and upward 2.0 mm after 6 months postoperatively, and then moved further backward 2.3 mm and downward 6.8 mm after more than 1 year from the predistraction position. Conclusion: In most cases, maxilla moved forward at distraction and started to move backward until 1 year after distraction, but remained forward, as compared with predistraction position. Maxilla also moved downward during distraction and upward in 6 months, but started descending in 1 year. There also was no further forward growth of the maxilla after distraction in growing children with clefts.
