Volume measurements of normal orbital structures by computed tomographic analysis.
Computed tomographic digital data and special off-line computer graphic analysis were used to measure volumes of normal orbital soft tissue, extraocular muscle, orbital fat, and total bony orbit in vivo in 29 patients (58 orbits). The upper limits of normal for adult bony orbit, soft tissue exclusive of the globe, orbital fat, and muscle are 30.1 cm3, 20.0 cm3, 14.4 cm3, and 6.5 cm3, respective...
متن کاملMeasurement of bony Orbital Volume with Computed Tomography (CT) in Healthy Eyes of Saudi Children
The bony orbit surrounding the eye is pyramidal with a rectangular base. The orbital volume (OV) of an adult is approximately 30 mm3 [1]. However, measurement of OV can be inconsistent due to the complicated anatomical structure of the bony orbit including the irregular inner border, holes and fissures. Computed tomography (CT) provides excellent image quality of bony landmarks making it a popu...
متن کاملAging of the bony orbit: a three-dimensional computed tomographic study.
BACKGROUND Facial aging is a dynamic process involving the aging of soft tissue and bony structures. The shape, size, and volume of the bony orbit have all been shown to change with increasing age. OBJECTIVE In this study, we demonstrate how specific bony aspects of the orbit change with age in both male and female subjects and what impact this may have on the techniques used in facial cosmet...
متن کاملPhotographic facial soft tissue analysis of healthy Iranian young adults: anthropometric and angular measurements
Background :Soft tissue profile can be widely different in various populations. Furthermore, this profile can be also continues to change throughout life. However, there are few studies that quantitatively evaluate the soft tissue profile in Iranian population. In order to determine normal reference values of facial parts in our populations, we aimed to measure standards for facial soft tissu...
