摘要：Back ground: The carotico clinoid foramen is formed by an osseous bridge between tip of the middle and anteriorclinoid processes of the sphenoid bone and transmits one of the segments of internal carotid artery (ICA).Context: The existence of a bony or osseous carotico clinoid foramen may cause compression, tightening orstretching of the ICA, especially of the clinoidal segment and cause complications in regional surgery.Purpose: The present study is an effort to study the carotico clinoid foramen in skulls and observe variousparameters like presence or absence, unilateral or bilateral, complete or incomplete, extent, dimensions of theligament, dimensions of the foramen and sexual dominance.Results: Presence of complete foramen was found in 12% and incomplete foramen was 26%. The mean width andthickness of the ligaments was found to be greater on the left side and greater in males. The size of the foramenwas found to be more on the left side and in males. Complete foramina were found to be more in males whileincomplete foramina were found equally in both sexes. Unilateral foramen were found to be more in femaleswhile bilateral foramina were found to be more in males.Conclusion: Considering the fact that most of the anatomy text books do not provide a detailed description of thecarotico clinoid ligament or foramen, the present study proves especially relevant to neurosurgeons in day today clinical practice.Implication: Knowledge of the prevalence of carotico clinoid foramen helps the neuro-surgeons for pre-operativescanning and precautions can be taken to prevent fatal complications during surgery. Further, removal of theanterior clinoid process is an important step in regional surgery, for which additional risk is involved. Thereforedetailed anatomical knowledge of the carotico clinoid foramen is of utmost importance, to increase the successof regional surgeries.
