Lower Cranial Nerve Function Following Jugular Foramen Tumor Resection

Abstract

Objective: Describe the presentation, tumor characteristics, and postoperative lower cranial nerve function following surgery for jugular foramen tumors. Method: Thirty jugular foramen tumor resections performed between 1989 and 2009 were reviewed. The mean age was 48.2 years (range, 18.6-77.7 years) at time of presentation. Surgical approaches included infratemporal fossa (70%), retrosigmoid (23%), transtemporal (20%), transcondylar (17%), and transcervical (17%). The mean follow-up was 4.6 years. Results: Combined surgical approaches were used in over 50% of the cases, and 60% underwent preoperative tumor embolization. Tinnitus was the most common presenting symptom, and middle ear or neck mass was the most common presenting sign. The most common diagnosis was paraganglioma. Six patients required tracheotomy, and 8 had feeding tubes at discharge. Fifty-seven percent of patients underwent speech or swallow therapy, 43% were treated with vocal cord injections, and 17% underwent medialization thyroplasty. Cerebrospinal fluid leak was uncommon (13%), and meningitis occurred in 1 patient. Normal or near-normal facial nerve function was maintained in 89% of patients. Conclusion: Resection of jugular foramen tumors carries a significant risk of lower cranial nerve dysfunction; however, long-term speech, airway, and swallowing morbidity can be minimized with contemporary ancillary surgical procedures.
