RESUMO
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.
RESUMO
Studying formation and development of fetal organ system, it has reliable information in medical theory as well as practical importance for the medical diagnosis, treatment and prevention in certain country. Introducing the modern advanced methods of fetal study in our country, it willbe possible to get the necessary information of prenatal organ development, formation and differentiation. Currently, the research works of eyeball development, topography, structures have not been accomplished yet in the Mongolian human fetuses. Therefore, the aim of thiswork was to make an evaluation of the development of the human eye during the fetal life. In our study, the 66 eyeballs of 33 human fetuses were examined.It was observed that the axial length, corneal diameter and equatorial diameter of the eye were increased simultaneously in the early fetal period. In the late period the axial length was increased slightly and equatorial diameter was increased rapidly. In the histological observation, the thickness of the eyeball layers were increased regularly from the early fetal period until the late fetal period. Thickness of the choroid and retina were increasing irregularly. Anti VEGFantibody was high distinguished detected in the choroid and retina in the early fetal period but it was middle distinguished detected in the late fetal period by immunohistochemistry.
RESUMO
Spinal dimensions (anterior, mid, and posterior height of the vertebral body) and shape variation (wedge compression, biconcave, and crush ratio) were obtained from plain radiographs of healthy Korean men and women. The purpose of this study was to define vertebral fracture from normal spinal morphometry of Korean men and women and to compare spinal dimension between men and women. Healthy 100 men and 100 women were included in this study. Plain lateral radiographs of thoracic and lumbar vertebrae were taken with standard method. Quantitative morphometry (anterior, mid, and posterior height of the vertebral body) was performed with plain radiographs. Spinal shape variations (wedge compression, biconcave, and crush ratio) were calculated from morphometric data. Spinal dimensions and shape variation of Korean men and women were presented, and morphometric cut-off vaiues for vertebral fracture were evaluated(mean-3xSD). Spinal dimensions of men were greater than women in all level (p<0.01). Wedge compression ratios (T6, 7, 8, 9, 12, L5 level) and biconcave ratios (T12, Ll, 4, 5 level) and crush ratios (Tll, L4, L5 level) were different between men and women (p<0.01). Spinal dimensions and shape variation from quantitative morphometry can be used in objective definition of vertebral fracture which can be used in medicolegal problem, workers compensation and medical insurance.
