Descrição

The contribution of carotid and vertebral angiography for surgical planning, particularly for the infratemporal approach, in 24 jugulotympanic paragangliomas with otoneurological symptoms is discussed. These symptoms included peripheral facial palsy, sensorineural hypoacusis, labyrinthine and nervous syndrome of the jugular foramen. Angiography was essential for the diagnosis of these tumors and, above all, for the rigorous evaluation of intrapetrous and apical invasion of the carotid artery, and also of extra and intradural posterior fossa extensions. Presurgical embolization, a relevant step in treatment, was based on the criterious evaluation of the angiotopographic pattern of the tumoral hypervascularization.
