title: [Preoperative mixed embolization of a paraganglioma using Onyx].
abstract: Paragangliomas, or glomus tumors, are highly vascular benign tumors of the head and neck. Clinical symptoms are essentially progressive and neurological, involving infiltration of the regional cranial nerves. The usual treatment is surgery, which itself is a challenge because of the close proximity of vital structures and the considerable blood loss. Preoperative embolization can reduce morbidity, and several techniques have been described using arterial injection of particles or of cyanoacrylate directly into the tumor. This case report is of a patient treated by surgery using a new technique-preoperative embolization involving both the arteries and veins, and injection of Onyx, resulting in complete devascularization of the tumor's arteriovenous network.
