Computed Tomography Scan Images of Sphenoidal Sinus Septa and Their Relations to the Internal Carotid Artery

Abstract

The trigeminal nerve and optic nerve, cavernous sinus optic chiasm, pituitary gland, and internal carotid artery are all encircled by the sphenoid sinus, which is located in the sphenoid. More than one asymmetrical vertical septa separate the sphenoidal sinus. Because of its position and linkages with important neurovascular and glandular systems, the sphenoid sinus poses a substantial diagnostic and therapeutic challenge. Objective: To look at the relationship between sphenoid sinus septation and the number and position of the internal carotid artery in people from Peshawar, Pakistan. Methods: The prospective study was conducted from November 2019 to April 2020 at the Radiology Department of a Khyber Teaching Hospital, Peshawar, the CT image was performed on 150 patients (100 males, 50 females) of the paranasal sinuses. From the originating axial slices, secondary coronal scans were obtained. Only individuals with no sphenoid sinus problems were included in the research to examine anatomical changes in the septation of the sphenoid sinus. Results: According to CT scans of the participants, 34% of males and 23% of females had more than one sphenoid septum, with 24 men accounting for 20.8 % and 16 female cases (16.8%) having the septum attached to the posterolateral wall of the sinus of the carotid canal. Conclusions: Prior to surgery, a CT scan of the paranasal sinuses is essential to rule out any potential complications caused by anatomical differences.
