ABSTRACT
The stereo-structure of the orbit is affected by several orbital diseases, e.g. congenital orbital dysplasia, orbital fracture, and intraorbital tumor. The three-dimensional (3D) reconstruction technique serves as a practical tool in diagnosis, surgical planning, and outcome prediction of plastic and reconstructive surgery. In our study, the morphologic features of the Mongolianadult orbit were described by 11 anatomic parameters using a 3D reconstruction technique and quantitative morphometry. The morphologic parameters of orbit such as bony orbital volume, orbital foramen area and orbital rim perimeter were measured on 3D models using this technique. Three-dimensional (3D) reconstruction based on high-resolution spiral computed tomography (CT) scans has been used for more than 10 years to reveal the anatomic location and morphologic features of orbital abnormalities and plays a important role in diagnosis, surgicalplanning, and outcome prediction. The findings of the study would allow for quantification of the orbital features of Mongolian adults and provide parameters for preoperative planning and prediction of postoperative outcome.
