Otoneurologic symptoms of temporal pyramidal neoplasms

: 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.
