Paragangliomas are neuroendocrine tumors originating from the extra-adrenal paraganglia of the autonomic nervous system. Most paragangliomas of the cervico-facial region are benign and slow growing, but 10% may have metastasis [1]. Jugulotympanic location represent the second most common tumor of the temporal bone. Treatment options for patients with head and neck paragangliomas include surgery, normofractionated external cortical radiation therapy (RT), stereotactic radiation therapy (SRS) or observation. The vital prognosis is good, but the functional prognosis remains critical especially for large tumors.
