Background: Carotid body tumours (CBTs) are rare but highly vascular neoplasms originating in the paraganglionic cells of the carotid bifurcation. Exact etiology of these tumors is not known. Male and female distributions are equal except at high altitude where females appear to predominate. Diagnosis of a chemodectoma usually begins with a color flow duplex scan. Magnetic resonance angiography are also useful, especially to evaluate bilateral disease. Conventional Arteriography with CT Angiography are valuable, especially in larger tumours, and are regarded as the best tools for diagnosis. The treatment of choice for carotid body tumours is surgical removal. Shamblin's classification system is used to categorize carotid body tumours based on their size and the difficulty of surgical resection. Results: It was observed that majority of the patients in this study were females numbering 35(79.45%) whereas there were 9 (20.43%) males. commonest age group involved was of patients 50 to 59 years of age. Surgery was done in all 44 (100%) patients with complete resection in 41 (93.07%) and incomplete in 3 (6.81%) patients. 10 (23%) were Shamblin grade 1, 29 (66%) grade 2 and 5 (11%) grade 3. ECA repair was done in 4 (9.08%) of patients, ICA repair in 2 (4.54%), ECA ligation in 2 (4.54%) and vascular graft was used in 1 (2.27%) of patients. 7 (15.89%) had transient cranial nerve palsy most commonly involving hypoglossal nerve. 3 (6.81%) had permanent cranial nerve palsy. In 6 (13.62%) patients there was local wound infection .There was post op stroke in 2 (4.54%) of patients. No operative mortality was seen.43 (97.61%) patients were proved to be paraganglionomas on HPE while 1 (2.27%) patients had inconclusive biopsy on Histopathological examination. Conclusion: Although rare, Carotid body tumor is still a pathology that we encounter in our experience and it should be kept in mind as a differential diagnosis for painless lateral neck masses.
