Abstract
The present paper was designed to analyze the dimensions of such important bony structures and surgical landmarks, which are used by many clinicians in many surgical interventions, in dry skull, cadaver, and healthy subjects on computed tomography (CT) images, and to determine whether there is a significant difference between these methods, and to obtain reference values from 3 different methods. Eight cadavers and 16 dry skulls and 100 three-dimensional (3D) CT images were studied. Necessary permissions for the study were obtained from Ethics Comittee. The 16 parameters were measured with an electronic digital caliper accurate 0.01 mm (LCD Digital Vernier Dial Microcaliper (INCA, DCLA-0605, 0.6–150 mm, USA). Also, the images obtained were transferred to the 3D Slicer (version 5.6.2) software program. Eight cadavers and 16 dry skulls of Turkish adults were unknown age and sex, whereas the mean age of females and males on CT images were 31.63±11.23 and 33.70±13.34 years, respectively. All values of the surgical landmarks for the anterior and middle cranial fossa obtained from cadavers, dry skulls, and 3D CT subjects (except length of lesser wing, anterior clinoid lengths for 2 sides, and width for right side) were statistically significant between 3 groups (P<0.05). This paper was conducted for the morphometric analysis of the specific regions of the anterior cranial fossa (ACF), and middle cranial fossa (MCF), which are used in neurosurgical procedures This detailed anatomic and radiologic reference values will be an extremely important source in the planning of both clinical and surgical approaches for neurosurgeon, anatomist, and radiologists.
