Abstract

The article presents the results of a study the aim was determination of the age-related changes in the morphometric indices of the vomer and the premaxilla in children with bilateral cleft lip and palate (BCLP) and premaxillary protrusion.
A retrospective analysis of computed tomography scans included the control group -115 children from six days up to 14 years of age and an foetus, the group with BCLP - 20 children from six days to eight years of age. The dimensions comprised the length, thickness and the optical density of the vomer and the premaxilla process.
The morphometric data of the vomer in the control group up to the age of 1 year showed: length-19.6±1.8mm, thickness - 1.63±0.25mm, density - 383±98 mg/cm3. The length and thickness vomer in children with BCLP were exceeds the length measured in those without BCLP by 1.6 times, density by 2.4 times (p<0.001). The vomer data in children aged 2 years and older in the control group were established: length -28.0±5.5mm, thickness – 1.62±0.35mm, maximum density in the middle part 742±120 mg/cm3. Children over 2 years old with BCLP possess a vomer that is 1.2 times longer and 2.3 times thicker on average in comparison with children without BCLP (p<0.001), maximum density in the caudal part 1168±187 mg/cm3 (p<0.05).
