ABSTRACT: Goal: The aim of this work is to study the relationship between the pneumatization of the adjacent structures of sphenoid sinuses and the protrusion of the neurovascular structures in the sinuses. Methods: A review of 225 CT scans skull was done for subjects aged at least 16 years old from November 1st to December 31st 2017. The pneumatization of adjacent structures of sphenoid sinuses and its relation with the protrusion of neurovascular structures surround the sinuses have been investigated. We used Fischer Exact test for comparison. The p value Results: Statistically significant associations were found between anterior clinoid process bilateral pneumatization and bilateral protrusion of carotid canal (p Conclusion: Compared to the literature, the prevalence of pneumatization of the adjacent structures of sphenoid sinuses was lower on Beninese than Caucasian and Asian. But there were the same correlations with the protrusion of neurovascular structures. In case of endonasal surgery of the sphenoid sinuses, surgeon should be aware of the high possibility the injury of optic nerves and internal carotid artery.
