Abstract
The charts of 35 patients were reviewed retrospectively to determine the effects of embolization on glomus jugulare tumors. Eighteen patients underwent embolization; 17 did not. All tumors were removed with a type A infratemporal fossa approach. The charts were evaluated for operative blood loss, operative time, length of hospitalization, new postoperative cranial nerve deficits and recurrence of tumor. Embolized patients had significantly less operative blood loss and operative time. Embolization did not affect length of hospitalization or reduce the incidence of new postoperative cranial nerve deficits. The surgeon's experience also plays a central role in reducing operative blood loss and operative time. The potential risks of embolization must be considered in the treatment regimen of glomus jugulare tumors.
