Abstract

Objectives Despite being pathologically benign, jugular foramen meningioma (JFM) may be locally aggressive and spread in three compartments. Because of the complex anatomical location, radical removal of JFM usually causes serious morbidity through lower cranial nerve (LCN) deficits. To accomplish long-standing tumor control with good functional outcomes, we report function-preserving multimodal treatment (FMT) for JFM, comprising the combination of intradural tumor removal with the preservation of LCN function and stereotactic radiosurgery (RS) for the residual tumor. Materials This study investigated six JFM patients (five women, one man). Preoperatively, five patients showed no LCN sign. Results All patients underwent function-preserving retrosigmoid intradural tumor removal, and no patient developed new LCN deficit. Three patients underwent RS for the residual tumor at 8 to 12 months after surgery. After RS, all three tumors were controlled. No patients showed tumor recurrence or new LCN deficits in the follow-up period (2 months to 8 years). Conclusion FMT for JFMs can accomplish long-standing tumor control with excellent functional outcomes.
