loss. The surgical approaches commonly employed for exci-
sion were the transcervical approach (9 cases) and the ITFA
(12 cases), whereas 1 case did not have surgery. Three cases
had PBO and 7 had intracarotid stent insertion. Gross total
removal was achieved in 19 cases, and 1 case had a recur-
rence. Eighteen cases had no dysphagia or were well com-
pensated after surgery. There were no significant complica-
tions noted in our series. Conclusions: In younger patients
with VP, surgery should be recommended. The proper pre-
operative endovascular intervention and surgical approach
facilitates gross total tumor removal. In the management of
bilateral or familial paragangliomas, careful and appropriate
decision making is essential. Copyright © 2011 S. Karger AG, Basel
Introduction
Vagal paragangliomas (VP) are rare neuroendocrine
neoplasms that may arise from paraganglia along the
course of the vagus nerve and account for approximately
5% of all head and neck paragangliomas, with an annual
incidence of 1 per 100000 population [Eriksen et al., 1991;
Lawson, 1980; Netterville et al., 1998; Persky et al., 2004;
Zanoletti and Mazzoni, 2006]. VP generally present as a
slow-growing neck mass which may protrude medially

Abstract
Background: The primary treatment of vagal paraganglio-
ma (VP) includes ‘wait and scan’, surgery and radiotherapy.
Objectives: To present the clinical findings, surgical treat-
ment including application of internal carotid artery (ICA)
stenting to facilitate surgery, and complications, as well as to
review the literature and to discuss the decision-making pro-
cess in the management of VP cases based on our experi-
ence and the literature. Design: A retrospective case review
of 22 cases with VP. Setting: Quaternary neurotologic and
skull base referral center. Material and Methods: The retro-
spective chart review identified 22 patients presenting with
VP. Our indication for surgery was VP in younger patients,
irrespective of the existence of vocal cord paralysis. Preop-
erative endovascular management of the ICA included per-
manent balloon occlusion (PBO) and stenting. The transcer-
vical approach and the infratemporal fossa approach type
A (ITFA) were used. Results: Fifteen cases had multicentric
paragangliomas, 5 cases bilateral tumors, 3 cases a genetic
mutation, and 2 cases a positive family history. The most
common symptoms were hoarseness, tinnitus and hearing
