The aim of the study was to describe the normal orbital volume and its most important relationships with other clinical variables.
We designed a correlation study and consecutive normal CTs scans were included. Orbital volume and facial anthropometrics were measured and correlated between them. Two independent and blind observers made all the measurements. Uni and multivariate statistical analysis were performed in order to create a predicting model for orbital volume.
A total of 199 consecutive patients were included in the study (398 orbits). The mean Orbital Volume (OV) was 24.5 ± 3.08 cc. Adequate intra and interobserver reliability was observed. There were no differences between the right and left orbit (p=0.73). The male average OV was 24.9 ± 3.03 cc, the female OV was 23.9 ± 3.08 cc. Age group analysis demonstrated a slow increase in OV beyond thirty years, but these differences were not significant (p=0.98). Only the age, total facial height, facial width and the interorbital distance were significant and were included in the predictive model of OV.
We have characterized the normal orbital volume,variations and associations. In order to further advance in the understanding of the clinical implications the abnormal orbital volume must be fully studied.
本研究旨在描述正常眼眶容积及其与其他临床变量的最重要关系。
我们设计了一项相关性研究，纳入了连续的正常 CT 扫描。测量眼眶容积和面部人体测量学，并对它们进行相关性分析。两位独立且盲目的观察者进行了所有的测量。进行了单变量和多变量统计分析，以创建眼眶容积的预测模型。
共纳入 199 例连续患者（398 只眼眶）。眼眶容积（OV）的平均值为 24.5±3.08cc。观察到足够的内部和观察者间可靠性。左右眼眶之间没有差异（p=0.73）。男性平均 OV 为 24.9±3.03cc，女性 OV 为 23.9±3.08cc。年龄组分析表明，OV 在三十岁以后缓慢增加，但这些差异无统计学意义（p=0.98）。只有年龄、总面高、面宽和眶距是显著的，并被纳入 OV 的预测模型。
我们已经描述了正常眼眶容积、变化和相关性。为了进一步深入了解异常眼眶容积的临床意义，必须对其进行全面研究。
