Glomus tympanicum and jugulare tumors arise within the middle ear and jugular fossa, respectively, but often extend into the adjacent areas of the skull base and posterior fossa. Multiple branches of the external carotid, internal carotid, and vertebral arteries may contribute to the vascular supply of these lesions. The arteriograms of 15 patients with glomus tumors were correlated with the surgical findings to determine if selective arteriography could define precisely the involvement within the middle ear, jugular fossa, and mastoid. The arteriographic mapping correlated well with the surgical findings in nine of 13 cases that had surgery, but a few important limitations were found. Therefore, a new arteriographic projection, called a transcanalicular view, is proposed that separates the middle ear from the jugular fossa, allowing for better visualization and assessment of the tumor blush.
鼓室球瘤和颈静脉球瘤分别起源于中耳和颈静脉窝，但常扩展至颅底和后颅窝的相邻区域。颈外动脉、颈内动脉和椎动脉的多个分支可能为这些病变提供血供。对15例球瘤患者的动脉造影结果与手术所见进行对比，以确定选择性动脉造影能否精确界定中耳、颈静脉窝和乳突内的受累情况。在13例接受手术的病例中，有9例动脉造影定位与手术所见相关性良好，但也发现了一些重要局限性。因此，提出了一种新的动脉造影投照方法，即经小管视图，它可将中耳与颈静脉窝分开，从而能更好地观察和评估肿瘤染色情况。
