Objective: To assess the prevalence of caroticoclinoid foramen (CCF) and its variations in Pakistani population using Multi detector Computerized Tomographic scans (MDCT).

Study Design: Cross-Sectional.

Place and Duration of Study: This study was conducted at the Department of Anatomy / Radiology, Ziauddin Hospital Clifton, Karachi from March 2022 to August 2022.

Materials and Methods: A total of 250 study participants including 138 males and 112 females presenting to Radiology Department of Ziauddin Hospital were included in the study. MDCT (head) was performed and sequential images were obtained. All images were evaluated on Vitrea software (version 5.1). Axial plane was used to evaluate types of CCF. Analysis of CCF was carried out according to Keyes classification.

Results: Type 2 CCF was found to be the most frequent type i.e.  69.6%, followed by type 1 with a frequency of 26.5%. Type 3 was observed less frequently, that is 3.7%. The frequency of CCF formation is found to be similar in both genders except that type 3 CCF is totally absent in females on the left side.

Conclusion: This study provides data regarding presence of CCF and its variations in Pakistani population. It suggests that a pre-operative CT scan should be mandatory before surgery in sellar and parasellar region to understand anatomical variations. This will help to modify the surgical technique accordingly in order to avoid any intraoperative complications.

Key Words: Caroticoclinoid foramen, sellar region, anterior clinoid process, surgical anatomy.
