| Sumario: | The knowledge of eye orbit anatomy is important for its diagnosis and surgical management. There are not many national reports about orbital morphometry. Different international studies agreed that there exists large variability according to geographic regions. From the Normal Anatomy Department, we proposed a morphometric study of the floor and the medial wall of the eye orbit in a sample from Córdoba, Argentina. The aim of this work is to produce a local database of the distance between the reference anatomical landmarks of the floor and medial wall of the orbit that are useful for interventions in the area.Thirty skulls provided by the Anatomical Museum Pedro Ara (Córdoba) were used; the distances between the anatomical landmarks were measured using a Mitutoyo digital caliber. The results were tabulated and the mean and standard deviation were calculated using the SPSS-Statistics program. The results of the distances obtained and their standard deviations in millimeters are: from the nasion (A) to the medial edge of the optical channel (E): 51(4.6); from the superior end of the posterior lacrimal crest (B) to the anterior ethmoidal foramen (C): 15(1.9); from C to posterior ethmoid foramen (D): 12(2.5); between D-E: 6(2.7); from the inferior vertex of the lacrimal ridges (F) to the inferior vertex of the optic canal (G): 41(3.7); from the lower orbital ridge at the level of the infraorbital foramen (H) to the intersection of the inferior orbital fissure and the infraorbital sulcus (I): 27(3.9); between H-G: 45(4.1); from H to the anterior end of the ethmoid-maxillary joint (J): 20(4.5); between H-F: 10(2.6); and between I-J: 19(2.8).The distance A-E and H-G represent the depth of the medial wall and orbital floor, respectively, A-E had lower values than those reported by other studies; the distances C-D, D-E, H-G and H-F are within the ranges of the literature. This study contributes to the production of local data on the main anatomical landmarks of the orbital floor and medial orbital wall. These data proves beneficial to surgeons in order to avoid potential problems when performing interventions in this region. |
