摘　　要：目的:探讨正常眼眶容积的发育规律。方法:应用螺旋CT(SCT)扫描及重建技术测量12 3例正常眼眶容积,分析其与年龄、性别、内眶距的关系,并观察2 1例筛窦炎患者与正常人的眼眶容积的差异。结果:14岁前眼眶容积增长迅速,正常成人眼眶容积男性大于女性,平均眼眶容积男女分别为2 5 .0 4±2 .37ml,2 2 .89±2 .6 7ml。眼眶容积与内眶距无相关,筛窦炎患者与正常人的眼眶容积差异无显著性意义。结论:SCT可用于眼眶容积的测量。Objective:To measure the orbital volume by spiral CT and studied its growth.Methods:123 patients (64males,59females) underwent CT scanning,the measurements were performated in the original or reconstructive CT images,The orbital volume,inner orbital distance.were measuremented,The difference among groups of age and sex were analyzed,the difference between normal orbital volume and ethmoiditis patient's were studied.Results:A strong linear correlation were observed between age and orbital volume(r=0.817,P<0.05) under 14 years,orbital volume in man is larger than in woman after14 years.The mean orbital volume in adult is 25.04±2.37ml in male,22.89±2.67ml in female.Conclusion:This study provides quantitative data,in normal subjects of different ages on the orbital volume.
