This cadaveric study analyzes the morphology and morphometry of the petrous and cavernous segments of the internal carotid artery (ICA) in 60 cadavers, documented over five years at Kalinga Institute of Medical Sciences. The petrous part predominantly exhibited a straight course, noted in 70% of cases, while the cavernous part mostly demonstrated a curved pathway, observed in 85% of instances. Notable anatomical variations were recorded, with a higher incidence in the cavernous part (25%) compared to the petrous part (20%). Morphometric measurements highlighted subtle differences in arterial diameters and lengths, which are critical for surgical interventions in the cranial base. This study underscores the necessity of understanding these anatomical nuances to enhance surgical precision and minimize risks during neurosurgical and otologic procedures. The insights gained are pivotal for both educational purposes and the advancement of surgical techniques in the context of complex skull base anatomy.
