Bibliogr. s. 38
Background: Paragangliomas (PGs) of the head and neck are relatively rare and represent 0.6% of all head and neck tumors and 0.03% of all tumors. There are four groups of head and neck PGs: carotid body tumors, vagal PGs, jugular PGs, and tympanic PGs. The resection of head and neck PGs carries an inherent risk of injury to cranial nerves and vascular structures which may lead to excessive bleeding. To plan the surgical strategy for PGs, detailed information about the vascular supply of the tumor is required. Material/Methods: Between January 1998 and April 2007, 41 tumors of the head and neck were identified in 37 patients (20 females, 17 males, mean age: 38.4 years). Single tumors were observed in 33 patients, two head and neck PGs were identified in 3 patients. and 1 patient presented 3 PGs, one of which was located laterally to the aortic arch. There were 21 PGs located at the carotid bifurcation, 10 in the jugular foramen, 6 in the tympanic cavity, and 4 along the course of the vagus nerve. Results: In all the cases of PGs located in the head and neck, the vascular supply came from branches of the external carotid artery. Vascular supply from the internal carotid and the vertebral arteries was not seen in any of the patients. The most common vascular supply in the cases of carotid body tumors and jugular PGs was the pharyngeal ascending artery. In the cases of vagal PGs it was the pharyngeal ascending artery and the posterior auricular artery and in the case of tympanic PGs the posterior auricular artery. Conclusions: DSA is an important tool in the diagnosis of head and neck PGs. The evaluation of its vascularization is essential in planning further treatment, both endovascular and surgical.
