Intradural jugular foramen tumors

Eleven patients with jugular foramen lesions with or without extradural extension were operated at University Hospital of Campinas (UNICAMP), in Campinas, Brazil, between 1998 and 2001. Neck dissection, mastoidectomy without transposition of the facial nerve and myofascial flap reconstruction of the cranial base with an especially developed technique were carried out in 7 patients. Four patients were operated using retrosigmoid craniectomy. Total excision was accomplished in 9 cases. All patients did not show evidence of disease progression at least after 2 years follow-up. There was no mortality. New lower cranial nerve deficits occurred in 5 patients. Nine maintain or improved their preoperative status based on Karnofsky and Glasgow Outcome Scale. A complex anatomy of this region demand wide exposures for treat those tumors. For this reason, an adequate approach for curative resection of most lesions and an efficient skull base reconstruction decreasing postoperative morbidity are essential.
