ABSTRACT
PURPOSE: The study aimed to see changes in the topography, prevalence, and diameter of the parietal emissary foramen (PEF) in children with advancing age.
METHODS: The 360 normal pediatric subjects aged 1-18 years, who underwent cranial computed tomography scans were included in the study. The diameter of PEF (PEFD), if present, was measured. Distances from PEF to sagittal (PEF-SS), lambdoid (PEF-LS), and coronal (PEF-CS) sutures were measured.
RESULTS: Of 360 children, 269 subjects had PEF (74.7%) and three had multiple PEFs (0.8%). Bilateral, unilateral right-side, and unilateral left-side PEF incidences were determined as 44.2%, 20.3% and 10.3%, respectively. PEFD was determined to be 3.16 ± 1.02 mm, and it remained unchanged after the early childhood period. PEFD > 5 mm was identified in six children (1.7%). PEF-SS, PEF-LS, and PEF-CS were measured as 5.44 ± 2.74 mm, 35.50 ± 6.44 mm, and 81.90 ± 7.33 mm, respectively. According to age groups, PEF-LS and PEF-CS did not change after the early childhood period. PEF-SS did not correlate with pediatric age groups. Linear function was calculated as y = 2.531 + 0.065 × age for PEFD, and y = 76.918 + 0.515 × age for PEF-CS.
CONCLUSIONS: Approximately three in four children have a PEF. Its diameter remains unchanged after the early childhood period. A pediatric PEF is located approximately 5 mm lateral to the sagittal suture, 35 mm anterior to the lambdoid suture, and 80 mm posterior to the coronal sutures.
