颅底病可分为原发、继发两种。颅底骨的原发病比其它骨的原发病多见。继发者多为邻近颅底的颅内、外病变直接侵犯。由于颅底的解剖弯曲和角度,加上咽与颈部软组织的影响,本区病变放射学显示困难,计算机断层扫描虽然克服了一些困难,但有些病例仍需通过血管造影和后颅窗脊髓造影才能确诊。直接、间接影响颅底的病变有多种,因此对颅底病变进行分类非常必要,但更重要的是颅底的区域划分。颅底可分为颅内侧面和颅外侧面。从上面来看,颅内侧面由前、中、后颅窝的底部 Skull base disease can be divided into primary and secondary types. The primary disease of the skull base is more common than the primary disease of other bones. Subsequent intracranial and extracranial lesions were mostly infringed upon by the secondary. Due to the anatomical curvature and angle of the skull base and the influence of the soft tissues of the pharynx and neck, the lesions in this area are difficult to perform radiologically. Although CT scans overcome some difficulties, some cases still require angiography and posterior cranial myelography. Can be diagnosed. There are many kinds of lesions that directly and indirectly affect the skull base. Therefore, it is necessary to classify the skull base lesions, but it is more important to divide the skull base area. Skull base can be divided into intracranial and extracranial. From the above, the intracranial side consists of the anterior, middle, and posterior fossa
