视神经损伤是鼻内鼻窦手术的严重并发症。视神经管突入蝶窦是一个主要的危险因素。在150项CT研究的前瞻性研究中，我们发现8%的病例存在这种解剖变异。它始终与同侧前床突骨化相关。未观察到视神经突入后筛房。CT是鼻内鼻窦手术患者术前检查的有用部分。轴向和冠状面图像获得或通过重建直接采集是必要的，以显示视神经的位置。
Damage to the optic nerve is a serious complication of intranasal sinus surgery. Protrusion of the optic canal into the sphenoid sinus is a major risk factor. In this prospective study of 150 CT studies, we found this anatomical variation in 8% of cases. It was consistently associated with pneumatisation of the ipsilateral anterior clinoid process. Protrusion of the optic nerve into the posterior ethmoid cells was never observed. CT is a useful part of the preoperative investigation of patients undergoing intranasal sinus surgery. Axial and coronal images obtained or by direct acquisition by reconstructions are necessary to show the position of the optic nerve.
