Long-term evidence for favorable midfacial growth after delayed hard palate repair in UCLP patients.
OBJECTIVE
To investigate whether delayed hard palate repair resulted in better midfacial growth in the long term than previously achieved with "conventional" surgical methods of palatal closure.


METHODS
Long-term cephalometric data from patients with unilateral cleft lip and palate were available from two Scandinavian cleft centers. The patients had been treated by different regimens, particularly regarding the method and timing of palatal surgery. Patients were analyzed retrospectively, and one investigator digitized all radiographs.


METHODS
Thirty consecutively treated subjects from each center, with cephalograms taken at three comparable stages between 10 and 16 years of age.


CONCLUSIONS
Patients whose hard palates were repaired late (early soft palate closure followed by delayed hard palate repair at the stage of mixed dentition) had significantly better midfacial development than patients in whom the hard palate was operated on early with a vomer flap, and then during the second year of life, the soft palate was repaired with a push-back procedure. As the growth advantage in the delayed hard palate repair group was accomplished without impeding long-term speech development, the delayed repair regimen proved to be a good alternative in surgical treatment of patients with unilateral cleft lip and palate.
