Cephalic index in the first three years of life: study of children with normal brain development based on computed...

Area of Science:

• Pediatric medicine
• Anthropology
• Medical imaging

Background:

• The cephalic index is crucial for surgical planning and assessing cranial deformation correction in children.
• Limited data exists on cephalic indices in healthy, young Caucasian children.
• Accurate cephalic index measurement is vital for pediatric craniofacial assessments.

Purpose of the Study:

• To establish a detailed cephalic index classification for healthy Caucasian children up to 3 years of age.
• To utilize high-resolution computed tomography (CT) for precise measurements.
• To provide normative data for pediatric craniofacial development.

Main Methods:

• 180 healthy Caucasian infants (83 female, 97 male) were analyzed.
• Participants were categorized into five age groups: 0-3, 4-6, 7-12, 13-24, and 25-36 months.
• Axial CT scans with 0.5 mm slices were used for accurate cephalic index calculation.

Main Results:

• The overall average cephalic index for children up to 3 years was 81.45 ± 7.06.
• Specific average indices were recorded for each age group: 80.19 (0-3m), 81.45 (4-6m), 83.15 (7-12m), 81.05 (13-24m), and 79.76 (25-36m).
• Mesocephaly was identified as the predominant skull shape.

Conclusions:

• A novel classification of cephalic indices for healthy, developing Caucasian children has been formulated.
• These findings are significant for anthropology, anatomy, forensic medicine, and genetics.
• The study provides essential reference data for pediatric craniofacial evaluations and interventions.
