Disorders of the paranasal sinuses, particularly the sphenoid sinus, can be associated with significant disorders of the optic and other cranial nerves. We examined 100 consecutive routine CT scans, 100 posterior fossa CT scans, and 100 MR scans to look for evidence of sinus disease, especially of the sphenoid sinus. The sphenoid sinus was abnormal in 7% of scans by all methods. Other sinuses were more frequently abnormal, including maxillary (23%), ethmoid (34%), and frontal (16%). Although MR was more sensitive in detecting sinus inflammation in the ethmoid and maxillary sinuses, the frequency of visible sphenoid sinus abnormalities detected by MR was not significantly greater when compared with CT. Of those patients with abnormal sphenoid sinuses, 24% had visual problems associated with the abnormality.
鼻窦疾病，尤其是蝶窦疾病，可能与视神经及其他颅神经的严重病变相关。我们检查了100例连续的常规CT扫描、100例后颅窝CT扫描和100例磁共振扫描，以寻找鼻窦疾病的证据，尤其是蝶窦疾病的证据。通过所有方法，蝶窦在7%的扫描中显示异常。其他鼻窦更常出现异常，包括上颌窦（23%）、筛窦（34%）和额窦（16%）。虽然磁共振成像在检测筛窦和上颌窦的鼻窦炎症方面更敏感，但与CT相比，磁共振成像检测到的可见蝶窦异常频率并没有显著更高。在蝶窦异常的患者中，24%有与该异常相关的视觉问题。
