Tumors extending into the nasal cavity, cranium, and paranasal sinuses have a number of distinctive features to take into consideration. Among them are the communication with an open air, high incidence of associated intracranial infections, specific complications (i.e. suppurative sinusitis, polyps, mucocele, pneumocephalus, nasal CSF leak). The features mentioned make these lesions unique. 50 consecutive patients underwent treatment in Burdenko Neurosurgical Institute. The diagnosis was confirmed either by CT, MRI, or at operation. Rhinological and otoneurological signs were also subjected to analysis. Most frequently these tumors (the majority of which were meningiomas (n = 34) extended into the nasal cavity (40 patients) and paranasal sinuses (n = 50). It was noted that the clinical signs vary depending on the histological type of tumor, its location and direction of growth (i.e. medial or lateral). Medially growing tumors usually involved 2-4 sinuses, while laterally growing tumors involved only one sinus. Among the symptoms, disturbances of smell, conductive hearing impairment, deformation of both the soft and hard palate, slowing of the experimental nystagmus due to disturbed extraocular movements. Some light is shed on the differential diagnosis, indications for various surgical approaches (transcranial, transnasal, and facial). The results of surgical treatment and postoperative complications are presented in the paper. The diagnosis and treatment of such patients require an interdisciplinary approach while would involve a team of a neurosurgeon, neuroradiologist, otoneurologist, and a neuro-ophthalmologist.
