A Morphometric Study of Anterior Clinoid Process and its Surgical Importance
Journal Title: Indian Journal of Anatomy - Year 2018, Vol 7, Issue 1
Abstract
Background: Knowledge about the unusual ossification of the Carotico-Clinoid Foramen (CCF), would be essential for neurosurgeons and radiologists in day-to-day clinical practice as internal carotid artery, optic nerve may get compressed. Aim: To obtain knowledge about morphometry of Anterior Clinoid Process (ACP), Optic Strot (OS) and the type of ossification of Carotico-Clinoid Foramen which would be beneficial to guide surgeries related to the cavernous sinus and internal carotid artery. Materials and Methods: A total of 135 half skulls were studied for various parameters such as the length of ACP from its base to the tip, the width at its base and the distance between the tip of ACP to optic strut were measured and were expressed in millimeters using digital calipers. SPSS 17th version was used for the statistical analysis. Paired t-test was applied to compare between right and left sides. Presence of carotico-clinoid foramen was observed and was classified as incomplete, contact form or complete. Results: The average length of ACP in the male skulls was 8.8±1.3 (right) and 8.40 ±1.4 mm (left). Its width was 7.9±1.4 mm and 7.5±1.0 mm. On female skulls the average length of the process was 8.48 ±1.6 mm on the right and 8.0 ± 1.4 mm on left side, while the width measured 7.3±1.5 mm (right) and 7.6±1.6 mm (left), on the opposite side. In our sample, a complete caroticoclinoid foramen appeared in male and female skulls were 9 (6.0%) and 8 (6.6%), contact form in male and female skull 6 (4.0%) and 3 (2.5%). At last, an incomplete form of the foramen in male and female were 21 (14%) and 19 (15.8%). The anatomic variations of the investigated structures must be considered during the approaches to the cavernous sinus and neurovascular elements of the sellar region. Conclusion: Considering the immense anatomical surgical and radiological importance of morphology of ACP, OS and CCF, this study highlighted the detailed morphometry of these structures.
