Assessment of the results of stereotactic radiation of glomus tumors according to clinical and radiographic information

Abstract

Glomus tumors are the most common tumors of the middle ear, occupying the second position among the temporal bone tumors after vestibulo-cochlear nerve neurilemmoma. The tissue of the jugular glomus is an interlacing of capillaries with the inclusion of epithelioid cells. Cytologically they are benign neoplasms, however, their clinical course can be described as aggressive due to their infiltrating growth and destruction of surrounding bone tissue. Such methods as microsurgical resection, embolization of the vascular stroma of the tumor, various types of radiotherapy and combinations of these methods are used for glomus tumors therapy. In FSAI NSPCN named after N. N. Burdenko most patients are sent to the Department of Radiology and Radiosurgery for stereotactic radiation. This study summarizes and analyzes the results of stereotactic treatment of patients with glomus tumors, both newly diagnosed and those after microsurgical excision with embolization for the entire period of this method application.
