The paper reports 3 cases of primary tumors in the temporal bone. The diagnosis was confirmed clinically, by CT and NMR-tomography findings. The pyramid tumors are characterized by involvement of the VII and VIII nerves and tactile disorders on the anterior and middle tongue. The images obtained visualized destruction foci. When the tumor spreads to the top of the pyramid, it destroys the function of the acoustic tube, the tympanic membrane acquires remarkable sucked-in appearance. Symptoms of focal neurological affection are usually absent, intracranial pressure is not elevated. The symptom complex may be incomplete depending the tumor location on the pyramid. Tumor lesion occurs in the pyramid or may invade the posterior cranial fossa.
本文报道了3例颞骨原发性肿瘤。通过临床、CT和核磁共振断层扫描结果确诊。岩尖肿瘤的特征是累及Ⅶ和Ⅷ神经以及舌前和舌中部的触觉障碍。所获得的图像显示有破坏灶。当肿瘤蔓延至岩尖顶部时，会破坏咽鼓管功能，鼓膜呈现出明显的内陷外观。通常没有局灶性神经病变症状，颅内压也不升高。根据肿瘤在岩尖的位置，症状复合体可能不完整。肿瘤病变发生在岩尖，也可能侵入后颅窝。
