Introduction: Radiologic evaluation is mandatory to assess the type of endoscopic approach concerning sinonasal pathology and reconstruction of fractured defects before any treatment modalities are instituted related to medial wall of the orbit. Objective: The goal was to provide improved understanding of the lamina papyracea variations and the relationship with the orbital morphometry. Methods: This retrospective study was performed using computed tomography scans of 200 orbits and results were compared with respect to age, sex, laterality and LP variations. Results: Lamina papyracea variations were categorized as type A, 80.5% (161/200); type B, 16% (32/200); type C, 3.5% (7/200). For medial wall the anterior and posterior lamina papyracea heights and angles were found as 17.14 mm, 147.88 degrees and 9.6 mm, 152.72 degrees, respectively. Also, the length of the lamina papyracea, the mean area of the orbital floor, medial wall, lamina papyracea and orbital entrance were 33.3 mm, 7.2 cm(2), 6.89 cm(2), 4.51 cm(2) and 12.46 cm(2) respectively. The orbital height and width were measured as 35.9 mm and 39.2 mm respectively. The mean orbital cavity depth was 46.3 mm from optic foramen to the orbital entrance and the orbital volume was 19.29 cm(3). We analyzed the morphometric measurements tending to increase with aging and greater in men and the relationship of them with lamina papyracea types. Conclusion: Precise knowledge of the lamina papyracea anatomy using computed tomography is essential for safer and more effective surgery and preforming the dimensions of an implant. In this way, the postoperative complications can be decreased and the best outcome can be provided. (C) 2019 Associacao Brasileira de Otorrinolaringologia e Cirurgia Cervico-Facial.
