Orbital encephalocele is a rare catastrophic complication of orbital roof fractures. Early diagnosis of this posttraumatic orbital encephalocele is very crucial because this condition if untreated leads to rapid loss of vision. Whenever displaced orbital roof fracture is identified in a head injury patient, an orbital encephalocele should be suspected. Although magnetic resonance imaging is the investigation of choice, computed tomography of orbit with thin axial and coronal sequences often gives the diagnosis. Frontobasal approach is the most commonly used surgical approach. Supra-transorbital approach is a minimally invasive alternative. Good results with regard to the orbital symptoms can be expected.
眶脑膨出是一种罕见的眼眶顶骨折灾难性并发症。早期诊断这种创伤后眶脑膨出非常关键，因为这种情况若不治疗会导致视力迅速丧失。每当在头部受伤患者中发现眼眶顶骨折移位时，就应怀疑有眶脑膨出。虽然磁共振成像为首选检查方法，但眼眶的计算机断层扫描采用薄层轴向和冠状序列通常也能做出诊断。额底入路是最常用的手术入路。经眶上入路是一种微创替代方法。有望在眼眶症状方面取得良好效果。
