Inferior rectus (IR) entrapment requires urgent surgical intervention in patients with traumatic orbital floor fracture (OFF). We evaluated 47 patients who underwent CT showing acute OFF, 10 of whom had surgically confirmed entrapment. Absent or trace dependent fluid in the ipsilateral maxillary sinus had sensitivity of 40% and specificity of 95% for entrapment. In comparison, sensitivity and specificity were 80% and 78% for IR thickening and 70% and 59% for sinus herniation of orbital contents.
下直肌（IR）嵌顿在创伤性眶底骨折（OFF）患者中需要紧急手术干预。我们评估了 47 名 CT 显示急性 OFF 的患者，其中 10 名患者经手术证实存在嵌顿。同侧上颌窦无或微量依赖液体对嵌顿的敏感性为 40%，特异性为 95%。相比之下，下直肌增厚的敏感性和特异性分别为 80%和 78%，眶内容物窦疝的敏感性和特异性分别为 70%和 59%。
