Computed Tomographic Localization of the Central Sulcus: A Morphometric Study in Adult Patients

Özet

AIM: To accurately describe the relations between the anatomical landmarks of the cranial convexity and the main cortical structures.MATERIAL and METHODS: A retrospective cross-sectional, observational study was performed. Computed tomography scans of71 adult patients with no pathological imaging were analyzed. The position of the bregma and the central sulcus was determined.The distances from bregma to the pre-central and post-central sulci were calculated. The relationships from the nasion and glabellato cortical structures were also assessed.RESULTS: The mean distances between the bregma and the pre-central, central and post-central sulci were 26.8 ± 7.2; 47.8 ± 5.9and 60.6 ± 5.7 mm, respectively, without gender discrepancy. The mean distance nasion-bregma and the nasion-related measuresshowed significant differences among sexes.CONCLUSION: The central sulcus was located accurately, on average 47.8 mm behind the bregma, which should be used insteadof nasion in order to avoid gender discrepancy. The data obtained provide useful and reliable information to guide neurosurgicalprocedures.
