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

Abstract

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.
