The present study describes the findings of a retrospective evaluation of dental models of 71 children (43 males and 28
females) with complete unilateral cleft lip and palate with ages ranging between 4 and 7 years, enrolled at the Hospital for
Rehabilitation of Craniofacial Anomalies (HRCA), University of São Paulo, in Bauru, Brazil. The patients were divided in control
and experimental groups according to the surgical protocols. The control group (surgical protocol of the HRCA) was comprised
of 47 patients and submitted to lip repair at least at 3 months of age (mean age of 8.72 months) and to palate repair at least
at 12 months of age (mean age of 20.34 months). The experimental group (surgical protocol proposed by Malek & Psaume) was
comprised of 24 patients and submitted to lip and soft palate repair at least at 3 months of age (mean age of 5.79 months) and
to hard palate repair at least at 18 months of age (mean age of 27.5 months).
The occlusal evaluation using the Goslon yardstick adapted by Atack showed a maxillary defficiency in both groups of
children with an average of 2.9; the findings show that the time of performance of the repairing surgeries of the palate,
concerning the early closure of the soft palate, does not cause significant occlusal differences, at least in the age range evaluated
in this study (4 to 7 years).
