Abstract:
BACKGROUND: The superior orbital fissure is a small area that connects the middle cranial fossa and the orbit. Many studies have measured the size of the superior orbital fissure. However, there is no standard value for the size of the superior orbital fissure. Therefore, we conducted this study to provide the average size of the superior orbital fissure in Korean adults. METHODS: We measured the widths of the superior orbital fissures of 142 patients using computed tomography scans. Because the width of the superior orbital fissure varies at different locations, we measured the superior orbital fissure width at the level of the optic canal. RESULTS: In the males, the width of the superior orbital fissure on both sides was 3.79±0.93 mm, and these values were 3.79±0.96 mm for the left side and 3.783±0.92 mm for the right side. In the females, the widths of the superior orbital fissures were 3.62±1.35 mm on the left side, 3.69±1.18 mm on the right side, and 3.65±1.26 mm across both sides. CONCLUSION: There were no significant differences between the males and females or between the left and right sides. The present study suggests that we may accept the hypothesis that a congenitally narrow superior orbital fissure may be a risk factor for the superior orbital fissure syndrome. Surgeons should take precaution with patients who have narrow superior orbital fissures during the perioperative period.
