A retrospective comparison of craniofacial form in Northern Irish children with unilateral cleft lip and palate.

ABSTRACT

OBJECTIVE: This study evaluated the craniofacial form of a sample of Northern Irish children with unilateral cleft lip and palate (UCLP). The quality of the outcomes achieved was compared with the outcomes reported for the six centers involved in the European multicenter study (Mars et al., 1992; Mølsted et al, 1992). DESIGN: Retrospective analysis. PATIENTS All children born with complete skeletal UCLP in Northern Ireland during the years 1983 to 1987. MAIN OUTCOME MEASURES: Cephalometric analysis was used to determine the craniofacial form and soft tissue profile. The quality of the dental arch relationships was independently assessed using the Goslon ranking system. RESULTS: The sample comprised 25 children with complete skeletal UCLP who had cephalometric radiographs and study casts recorded at a mean age of 9.4 years (range, 8 to 11 years). Cephalometric analysis revealed no important skeletal differences between the Northern Irish UCLP children and the published results from the six Eurocleft centers. The soft tissue profile of the Northern Irish UCLP children was significantly more convex than the soft tissue profile recorded for center D in the Eurocleft study. The Goslon ranking system revealed that 18 (72%) of the Northern Irish UCLP children had good or satisfactory dental arch relationships. CONCLUSIONS: No clinically important differences were detected between the mean cephalometric skeletal parameters of the Northern Irish UCLP children and those published for the six cleft centers involved in the Eurocleft study. On average, the Northern Irish UCLP children were found to differ significantly from Eurocleft's center D in their soft tissue facial contour and sagittal lip profile. The quality of the dental arch relationships of the Northern Irish sample was between the best and the less good Eurocleft centers.
