dc.description.abstractBackground: The relationship between the intraorbital structures and medial wall of the orbit is essential for surgical approaches. Objective: The goal was to provide an improved understanding of the dimensions of extraocular muscles and the approximate location of the intraorbital structures with respect to the lamina papyracea (LP). Material and Methods: This retrospective study was performed using the multiplanar reconstruction of Computed Tomography (CT) scans of 200 orbits. Results: We measured the mean diameters of intraorbital structures. The mean horizontal distances from LP to medial and inferior rectus muscles, globe, and infraorbital canal were found as 3.9 +/- 1.2 mm, 11.5 +/- 1.6 mm, 7.8 +/- 1.5 mm and 16.1 +/- 2.0 mm and as 0.6 +/- 0.4 mm, 4.7 +/- 1.3 mm, 7.2 +/- 1.8 mm, 12.5 +/- 2.3 mm at the depth of the anterior (AEF) and posterior ethmoidal foramen, respectively. All morphometric results were compared with respect to age, sex and laterality and higher in males than females. The measurement results indicated that subjects in first and second age groups showed statistically significant differences in distances from the LP to the globe, medial and inferior rectus muscles at the depth of AEF (p<0.05). But, there was no difference between right and left. Conclusion: CT imaging which can offer an accurate understanding of the regional anatomy of and around the LP may be helpful in preoperative planning and prediction of postoperative outcomes. It can allow the surgeon to prevent possible orbital injury during surgical interventions.en_US
