Location of the Optic Foramen Relative to the Sphenoid Sinus and Orbital Apex Structures

Background: Orbital decompression is performed to reduce intraorbital pressure by removing the fat tissue and bone around orbit. Access proper equipment, experienced personnel, adequate anatomical knowledge are essential perform this procedure. To achieve maximum decompression, surgeons need open orbit up apex, including optic foramen annulus of Zinn. Objectives: This study aimed determine location sphenoid sinus relative using computed tomography (CT) scan, which for orbital surgery, in Central Anatolia Region, Turkey. Patients Methods: cross-sectional was conducted on 64 patients from Turkish population between March 15 April 15, 2021 Region. The were selected purposive sampling method. Based cranial CT scans, a total 128 orbits evaluated hospital’s picture archiving communication system. included admitted hospital with headache. However, their images, an radiologist, reported be normal. relationship anterior surface examined, determined as anterior, posterior, or equal sinus. Descriptive statistics measured statistical analysis. Results: participants 32 men women age range 20 - 67 years. analyses, mainly opposite aspect both females males; finding more prominent females. In right orbit, mean distance +6.97 mm if sinus, while it -4.1 located posteriorly Similarly, left anteriorly, -4.15 position symmetrical 60.9% cases two orbits. Conclusion: results sinus; frequently observed (59.4%) than males (40.6%). present can provide further information surgeries posterior
