Abstract
Paragangliomas are neuro-endocrine tumors of the extra-adrenal paraganglionictissues derived from neural crest and has been recognised as a part of the AminePrecursor Uptake and Decarboxylation of Pearse (APUD) system. They are found in the head and neck region commonly as carotid body tumors, glomus jugulare, glomustympanicum, glomus vagale , and sympathetic paragangliomas. Surgical excision is the preferred treatment of head and neck paraganglioma. Safe surgical excision requires; good preoperative planning based on angiographic study and preoperative hemodynamic carotid & cerebrovascular flow studies, Wide surgical exposure, meticulous hemostasis assisted in selected cases by preoperative embolization, proximal and distal vascular control, careful dissection of all major neurovascular structures, & co-operation of a vascular surgeon skilled in carotid reconstructive techniques.
