title: Neurologic manifestations of glomus tumors in the head and neck.
abstract: In 75 patients with glomus tumors in the head and neck region, 57 tumors arose from the jugular bulb region, 11 from the middle ear, and seven from the vagus nerve. Thirty-seven percent (28 patients) had cranial nerve paralysis, and 14.6% (11) had intracranial tumor extension. The jugular foramen syndrome was associated with a 50% (two of four patients) incidence, and hypoglossal nerve paralysis with a 75% (three of four) incidence of posterior fossa tumor invasion. Horner syndrome and labyrinthine destruction had a 50% (two of four) incidence of a middle cranial fossa tumor invasion. The incidence of central nervous system (CNS) invasion with cranial nerve paralysis (excluding the seventh nerve) was 52% (11 of 21). Otologic findings and seventh nerve paralysis did not correlate with CNS tumor extension.
