Accurate quantitative data of the adult bony orbital volume and dimension are needed for treatment optimization. In the present study, the authors aim to evaluate adult orbital volume and corresponding linear dimensions according to age, volume, and individual symmetry.
Seventy computerized tomography facial scans of adults were randomly chosen from an institutional database and 3-dimensionally reconstructed. Studies were excluded for orbital pathology or incomplete radiographic data. Anatomic landmarks were marked. Interval linear distances and orbital volumes were calculated. Data were analyzed using paired T-tests, independent T-tests, linear regression analysis, and 1-way analysis of variance.
A total of 140 orbits from 70 patients were analyzed (female = 35, male = 35), ranging from 20 to 88 years of age. Orbital volume was similar between an individual's left and right side; however, a difference was observed in vertical orbital height, orbital width, inferior orbital rim position, orbital roof length, orbital width, and medial orbital wall length (0.45, 0.64, 0.4, 0.77, 0.97, and 5.1 mm, respectively; P < 0.05). In comparison to females, males averaged larger orbital volume by 3.07 cm (29.58 cm versus 26.51 cm, P = 0.0002), medial wall length by 2.66 mm (P < 0.05), and orbital width by 2.66 mm (P < 0.05). Orbital volume did not correlate with patient age, while lateral wall length was correlative.
This accurate normative data of the adult bony orbit impacts key aspects of patient diagnosis and treatment and also suggest clinical signs of periorbital aging are not due to bony orbital changes.
为优化治疗方案，需要准确的成人眼眶骨体积和尺寸的定量数据。在本研究中，作者旨在根据年龄、体积和个体对称性评估成人眼眶体积及相应的线性尺寸。
从机构数据库中随机选取70例成人计算机断层扫描面部图像并进行三维重建。排除有眼眶病变或放射影像数据不完整的研究。标记解剖标志点。计算间隔线性距离和眼眶体积。采用配对t检验、独立t检验、线性回归分析和单因素方差分析对数据进行分析。
共分析了70例患者的140个眼眶（女性35例，男性35例），年龄范围为20至88岁。个体左右眼眶的体积相似；然而，在眼眶垂直高度、眶宽、眶下缘位置、眶顶长度、眶宽和眶内侧壁长度方面存在差异（分别为0.45、0.64、0.4、0.77、0.97和5.1毫米；P<0.05）。与女性相比，男性的平均眼眶体积大3.07立方厘米（29.58立方厘米对26.51立方厘米，P=0.0002），内侧壁长度长2.66毫米（P<0.05），眶宽长2.66毫米（P<0.05）。眼眶体积与患者年龄无关，而外侧壁长度相关。
这些准确的成人眼眶骨标准数据影响患者诊断和治疗的关键方面，也表明眶周衰老的临床体征并非由眼眶骨变化引起。
