目的探讨眶壁骨折HRCT诊断价值及其司法鉴定的应用价值。方法回顾性分析98例眶壁骨折的临床及CT诊断资料,所有病例均行眼眶横断位HRCT扫描,MPR、SSD重建,必要时加冠状位CT扫描。结果98例眶壁骨折中:眶内壁骨折77例,表现为眶内壁凹陷,骨折片移位伴眼睑肿胀、眶内积气、筛窦积血、内直肌增粗、软组织及脂肪疝入;眶下壁骨折25例;眶外壁骨折17例;眶上壁骨折15例;视神经管壁骨折6例。结论眶壁骨折首选眼眶横断位HRCT扫描,对眶壁骨折的诊断具有重要价值,有助于临床治疗和预后的判断。
Objective To investigate the diagnostic value of HRCT orbital fracture and its application in forensic identification. Methods The clinical and CT diagnostic data of 98 cases of orbital fracture were retrospectively analyzed. HRCT, orbital orbital HRCT, reconstruction of MPR and SSD were performed in all cases. Coronal computed tomography was used when necessary. Results In 98 cases of orbital fractures, 77 cases of orbital wall fractures manifested as invagination of the orbital wall, displacement of the fracture plate with eyelid swelling, orbital pneumatosis, ethmoid hemorrhage, thickening of the rectus muscle, infiltration of soft tissue and fat; 25 cases of infraorbital fracture, 17 cases of orbital wall fracture, 15 cases of supraorbital fracture, and 6 cases of optic canal wall fracture. Conclusion The orbital wall fracture orbital HRCT scan is of great value in the diagnosis of orbital fracture, which is helpful for clinical treatment and prognosis judgment.
