Abstract

Background and objective: Computed Tomography, provides a direct visual window into the morphological anatomy of the orbit. The morphometric information of the human orbit is of great importance to ophthalmologists, rhinologists, facial plastic surgeons, forensic experts as well as maxillo-facial surgeons. Purpose of the present study is to do morphological study of human adult orbit using randomly selected computed tomography images. Materials and Methods: Ours is a cross-sectional study where in 100 randomly selected computed tomography films of skull were studied in the department of ENT at Navodaya Medical College, Raichur during the month of January 2017. The morphological parameters of the orbit which were studied include shape, height, breadth, perimeter and orbital index. Results: Of the total 200 orbital readings in the total of 100 CT films, 94 (47%) orbits were round in shape and 106 (53%) orbits were in square shape. The mean height of the orbit was 3.58 cm (SD ±0.41). The mean breadth of the orbit was 4.18 cm (SD±0.47). The mean perimeter of the orbit was 12.58 cm (SD±0.94). The mean orbital index was 75.28 (SD±9.05). Conclusion: Computed Tomography, provides a direct visual window into the morphological anatomy of the orbit. The morphometric information of the human orbit is of great importance to ophthalmologists, rhinologists, facial plastic surgeons, forensic experts as well as maxillo-facial surgeons.
