三维（3D）重建技术作为一种实用的工具，在诊断，手术计划，并预测结果的整形和重建手术。本研究应用三维重建技术，用11个解剖参数描述了中国成人眼眶的形态学特征。从接受颅面计算机断层扫描（CT）诊断颅面或眼眶畸形以外疾病的患者中随机选择64名中国成年人。利用该技术在三维模型上测量眼眶骨性容积、眶孔面积和眶周周长等眼眶形态学参数。研究了两种轨道之间以及两种性别之间的差异。该方法的测量结果具有较高的重现性。除眶高外，其他各项解剖参数均存在显著性差异。男性和女性眼眶骨体积分别为26.02和23.32 mL，眶孔面积分别为11.80和11.10 cm 2，眶缘周长分别为12.65和12.20 cm，眶高分别为33.35和33.22 mm，眶宽分别为40.02和38.00 mm;平均眶底长47.93和46.18 mm，平均眶顶长52.93和50.89 mm，平均眶内壁长46.43和44.41 mm，平均眶外侧壁长48.38和46.91 mm，平均眶内距离27.18和25.11 mm，平均眶外距为98.77和93.69 mm。根据眼眶容积和其他解剖参数，两个眼眶是对称的。女性的眼眶尺寸明显小于男性;然而，眼眶高度相似。本研究的结果可以量化的中国成年人的眼眶特征，并提供参数，术前规划和预测术后结果。
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 Chinese adult orbit were described by 11 anatomic parameters using a 3D reconstruction technique. Sixty-four Chinese adults were selected randomly from patients who had undergone craniofacial computed tomography (CT) scans to diagnose conditions other than craniofacial or orbital deformations. 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. Differences between the two orbits and between the two sexes were investigated. The method of measurement showed high reproducibility of results. No difference between the two orbits was found. There were significant differences between men and women in all anatomic parameters other than orbital height. In men and women, respectively, mean bony orbital volume was 26.02 and 23.32 mL, mean orbital foramen area 11.80 and 11.10 cm2, mean orbital rim perimeter 12.65 and 12.20 cm, mean orbital height 33.35 and 33.22 mm, mean orbital width 40.02 and 38.00 mm; mean orbital floor length 47.93 and 46.18 mm, mean orbital roof length 52.93 and 50.89 mm, mean medial orbital wall length 46.43 and 44.41 mm, mean lateral orbital wall length 48.38 and 46.91 mm, mean intraorbital distance 27.18 and 25.11 mm, mean extra-orbital distance 98.77 and 93.69 mm. It is concluded that the measurements of these orbital parameters could be obtained from a 3D reconstruction method. The two orbits were symmetric based on orbital volume and other anatomic parameters. Orbital size was significantly smaller in women than in men; orbital height, however, was similar. The findings of the present study allow for quantification of the orbital features of Chinese adults and provide parameters for preoperative planning and prediction of postoperative outcome.
