Cranial nerve preservation in lesions of the jugular fossa

Abstract

The most significant objection to the proposal of lateral transtemporal cranial base surgery for the treatment of jugular foramen tumors is the perceived lasting morbidity attendant to aggregate cranial nerve loss. As techniques become more standardized and earlier diagnosis generates smaller tumors for treatment, outcome has become more predictable. Surgery has become the recognized management preference for these cranial base lesions. The purpose of this article is to assess the role of surgery in the treatment of jugular foramen lesions, as well as to review some of the technical highlights of conservation surgery, its clinical prerequisites, and reasonable expectations. We review 100 lateral skull base surgical cases of lesions involving the jugular foramen. The majority of these lesions--77 of 100--were paragangliomas. For these glomus tumors, cranial nerve preservation correlated well to tumor size and location. The diversity of the remaining 23 cases prevented any substantive conclusions.
