Incidence of cranial nerve palsy after preoperative embolization of glomus jugulare tumors using Onyx

Abstract

Embolizing glomus jugulare tumors with Onyx can produce a dramatic reduction in tumor vascularity. However, the intimate anatomical relationship and overlapping blood supply between these tumors and cranial nerves may contribute to a high incidence of cranial neuropathy following Onyx embolization.
