Objective: To investigate the association between cleft size in infancy and crossbite at 5 years of age in children with cleft palate (CP) and unilateral cleft lip and palate (UCLP). Design: Retrospective study. Setting: University Hospital, Uppsala, Sweden. Patients: Dental study models of 80 consecutive children, 51 children with CP and 29 children with UCLP, born between 1990 and 1999 were analyzed. Interventions: Lip repair at 3 to 4 months in UCLP children. Primary soft palate repair at 6 to 10 months and secondary hard palate closure at 25 to 26 months of age. Main Outcome Measures: Maxillary arch dimensions and cleft size were measured on infancy dental casts. At follow-up at 5 years, crossbite scores were registered on dental study models. Results: The cleft dimensions in infancy showed large interindividual variation. Mean posterior cleft width was larger in UCLP children than in children with CP. The UCLP group also had significantly more crossbite at 5 years than the CP group. No significant association was noted between initial cleft size and crossbite scores at 5 years in the CP group. For the UCLP group, larger cleft widths at the level of the cuspid points were significantly associated with less anterior and posterior crossbite. Conclusions: The findings support the hypothesis that cleft size in infancy affects early outcome with respect to crossbite in children with UCLP, but not in children with CP.

Abstract [en]

The wide variation in infant maxillary morphology and cleft size of children with unilateral cleft lip and palate (UCLP) and isolated cleft palate (CP) raise concerns about their possible influences on treatment outcome. The studies in this thesis aimed to investigate the relation between cleft size in infancy and crossbite at 5 years of age (Paper I); the impact of primary surgery on cleft size and maxillary arch dimensions from infancy to 5 years of age (Paper II); associations between cleft size, maxillary arch dimensions and facial growth in both UCLP and CP children (Paper III); and, to evaluate the relation between infant cleft size and nasal airway size and function in adults treated for UCLP (Paper IV).

In homogenously treated groups of children with UCLP and CP, dental casts were used to measure cleft size and maxillary arch dimensions from infancy up to 5 years of age, and for crossbite recording at 5 years. Serial lateral cephalometric radiographs taken between 5 and 19 years of age in the same groups were used to study facial growth. Nasal airway size and function were evaluated by acoustic rhinometry, rhinomanometry, peak nasal inspiratory flow and odour test in a group of adults treated for UCLP.

The main findings were: crossbite was a frequent malocclusion at 5 years of age in children with UCLP and large cleft widths at the level of the cuspid points in infancy were associated with less anterior and posterior crossbite in this group (Paper I). Cleft widths decreased after lip closure and/or soft palate closure in both UCLP and CP children. Initially, UCLP children had wider maxillary arch dimensions, but after hard palate closure, the transverse growth was reduced, and at 5 years, they had smaller maxillary arch widths than CP children had (Paper II). Maxillary arch depths and cleft widths in infancy were correlated with maxillary protrusion and sagittal jaw relationships in both UCLP and CP children (Paper III), but cleft width in infancy was not correlated with nasal airway size and function in adults treated for UCLP (Paper IV).
