Glomus Tympanicum Tumor With Middle Cranial Fossa Extension
Published 1987 · Medicine
Glomus tumors of the temporal bone present a wide spectrum of pathoses, which range from small tumors (limited to the middle ear) to more extensive lesions of the skull base, with cervical and intracranial spread. Although treatment of these lesions is primarily surgical, the choice of surgical approach depends on the location and size of the tumor, as determined by preoperative radiologic evaluation. According to the Glasscock-Jackson classification, I glomus tympanicum tumors may be staged according to extent of tumor invasion. In this classification, there is no acknowledged possibility of invasion of the middle cranial fossa by glomus tympanicum tumors. Such tumors, however, do exist, and should be recognized preoperatively in order to facilitate the most appropriate surgical approach.
