Juvenile nasopharyngeal angiofibroma is a highly vascular neoplasms that tends to spread in the various fissures and foraminia of the nasopharynz. Polytomography and angiography have added greatly to the diagnosis and management of this tumor through accurate preoperative assessment. Computed tomography has given an additional sophisticated, precise method for evaluating the extent of juvenile nasopharyngeal angiofibroma. Computed tomography shows, in detail, the extension of the tumor into the pterygopalatine fossa with widening of the pterygopalatine fossa and anterior bowing of the posterior wall of the maxillary sinus. With this correct information about tumor location, surgical or radiation treatment can be appropriately planned, with a probable improvement of cure rates and reduction of recurrences.
青少年鼻咽血管纤维瘤是一种血管丰富的肿瘤，易于在鼻咽的各个裂隙和孔道中蔓延。断层摄影术和血管造影术通过准确的术前评估，极大地辅助了该肿瘤的诊断和治疗。计算机断层扫描为评估青少年鼻咽血管纤维瘤的范围提供了一种更为精细、精确的方法。计算机断层扫描详细显示了肿瘤向翼腭窝的扩展情况，表现为翼腭窝增宽以及上颌窦后壁向前凸出。有了关于肿瘤位置的准确信息，就可以合理规划手术或放射治疗方案，有望提高治愈率并减少复发率。
