Abstract
OBJECTIVE: The primary research aim of this study was to compare long-term differences in craniofacial morphology at adulthood between two groups of unilateral cleft lip and palate (UCLP) patients: one operated by primary periosteoplasty and the other by primary bone grafting. DESIGN: The two groups were followed longitudinally at 5-year intervals; this study examined the 15- to 20-year age range. SETTING: University hospital/center located in Prague, Bohemia, Czech Republic. PATIENTS: 17 men with primary bone grafting, 29 men with primary periosteoplasty. INTERVENTIONS: Primary bone grafting or periosteoplasty. METHODS: Serial cephalometric radiographs. MAIN OUTCOME MEASURES: Conventional cephalometric and finite element measures. RESULTS: The mandibular symphysis was larger in the bone-grafted group. The periosteoplasty group displayed a more horizontal growth of the mandible with less rotation than the bone-grafted group. There were no other significant differences. CONCLUSIONS: We conclude that the original outcomes differences observed in childhood and adolescence were masked by skeletal and dental compensations in adulthood. These observations can be attributed to both natural growth and clinical intervention.
