Neurogenic Tumors of the Jugular Foramen

Schwannomas and neurfibromas comprise the vast majority of nerve sheath tumors of the jugular foramen. The growth and presentation of these tumors are variable and may not necessarily be associated with lower cranial neuropathies.

Since 1974, 270 temporal bone paragangliomas have been resected at the University of Zurich. The percentage of tumors completely excised is 80% (Table 83-5). The operating time
