To determine the influence of different types of orbital fractures on the radiographic post-treatment outcomes.
The investigation was a retrospective cohort study involving CT data of all patients who underwent delayed primary or secondary surgery for orbital/zygomatico-orbital trauma between 2019 and 2021. The sample was divided into three groups 1, 2, and 3: isolated floor, floor and medial wall, and combined orbit and zygomatic complex fractures. The type of orbital fracture was the exposure, while the outcome measures were reduction in enophthalmos and intraorbital volume and linear relationship between the two variables. Data were analyzed for variance between groups and association. Statistical significance was set at < 0.05.
Forty-four patients (3 females and 41 males) with a mean age of 28.6 years were included in the study. Reductions in enophthalmos ( P < 0.001) and intraorbital volume ( P = 0.003) demonstrated significant variance between the groups. For every cubic centimeter of reduction in volume, the reduction in enophthalmos was 0.78 mm ( P < 0.001) in isolated floor fractures, 0.60 mm ( P = 0.013) in combined fractures involving the floor and medial walls, and 0.24 mm ( P = 0.456) in combined fractures of the orbit and zygoma.
Correction of enophthalmos strongly depends on the type of orbital fracture. There exists a significant linear relationship between enophthalmos and intraorbital volume in fractures involving the internal orbit.
确定不同类型眼眶骨折对治疗后影像学结果的影响。
本研究为一项回顾性队列研究，纳入了2019年至2021年间因眼眶/颧眶部外伤接受延迟一期或二期手术的所有患者的CT数据。样本分为三组：1组、2组和3组，分别为单纯眶底骨折、眶底和眶内壁骨折、眼眶与颧骨复合体联合骨折。眼眶骨折类型为暴露因素，而结局指标为眼球内陷的改善程度、眶内容积以及这两个变量之间的线性关系。分析组间差异及关联性数据。设定统计学显著性水平为<0.05。
本研究纳入了44例患者（3例女性，41例男性），平均年龄28.6岁。三组间眼球内陷改善程度（P<0.001）和眶内容积（P = 0.003）差异有统计学意义。对于每立方厘米的容积减少，单纯眶底骨折患者眼球内陷减少0.78毫米（P<0.001），眶底和眶内壁联合骨折患者眼球内陷减少0.60毫米（P = 0.013），眼眶与颧骨联合骨折患者眼球内陷减少0.24毫米（P = 0.456）。
眼球内陷的矫正很大程度上取决于眼眶骨折的类型。在内侧眼眶骨折中，眼球内陷与眶内容积之间存在显著的线性关系。
