The distance between the orbits and their individual dimensions are important in the diagnosis of craniofacial anomalies. Most observers rely on standard radiographs for measuring the bony interorbital distance. Tomography of the skull base and orbital computed tomography (CT) can also be used. This article describes the normal range of the bony interorbital distance and other useful orbital linear and angular measurements as determined from a series of CT scans of the orbits in 400 adults who had CT for other purposes. The normal interorbital distance measured at the posterior border of the frontal processes of the maxilla on nonrotated scans, in the plane of the optic nerve, ranges from 2.29 to 3.21 cm (average, 2.67 cm) in men and 2.29 to 3.20 cm (average, 2.56 cm) in women. The widest interorbital distance lies behind the posterior poles of the globes. This ranges from 3.16 to 4.10 cm (average, 3.37 cm) in men and 2.93 to 3.67 cm (average, 3.20 cm) in women.
眶间距离及其各自的尺寸在颅面畸形的诊断中很重要。大多数观察者依靠标准X线片来测量骨性眶间距离。颅底断层扫描和眼眶计算机断层扫描(CT)也可使用。本文描述了从400名因其他目的进行CT扫描的成年人眼眶系列CT扫描中确定的骨性眶间距离的正常范围以及其他有用的眼眶线性和角度测量值。在未旋转扫描上,于上颌骨额突后缘、视神经平面测量的正常眶间距离,男性为2.29至3.21厘米(平均2.67厘米),女性为2.29至3.20厘米(平均2.56厘米)。眶间距离最宽处位于眼球后极后方。男性此距离为3.16至4.10厘米(平均3.37厘米),女性为2.93至3.67厘米(平均3.20厘米)。
