Tomographic Morphological Study of the Cranium and Its Correlation with Cranial Halo Use in Adults

OBJECTIVE To evaluate using tomographic study the thickness of the cranial board at the insertions points of the cranial halo pins in adults. METHODS This is a retrospective, cross-sectional, descriptive analysis of Computed Tomography (CT) scans of adult patients' crania. The study included adults between 20 and 50 years without cranial abnormalities. We excluded any exam with cranial abnormalities. RESULTS We analyzed 50 CT scans, including 27 men and 23 women, at the original insertion points and alternative points (1 and 2 cm above the frontal and parietal bones). The average values were 7.4333 mm in the frontal bone and 6.0290 mm in the parietal bone. CONCLUSION There was no statistically significant difference between the classical and alternative points, making room for alternative fixings and safer introduction of the pins, if necessary. Level of Evidence II, Retrospective Study.
