The prevention of relapse after maxillary osteotomies in cleft palate patients

The use of segmental osteotomies to treat surgically severe malocclusion in cleft patients is discussed. The coordinated approach by orthodontist and surgeon is advocated and the advantage of such an approach is stressed. The method allows for the simultaneous correction of the skeletal deformity and closure of residual oro-nasal perforation. The relapse tendency in both antero-posterior and transverse dimensions appeared to be minimal as found in this study of 18 patients.
