CAROTID BODY TUMOUR

Abstract

Introduction

Carotid body tumours are usually benign lesions. Carotid bodies are located on the posteromedial wall of the common carotid at its bifurcation and measures 3 to 5 mm. the feeding vessels primarily run from external carotid artery. Its function is related to its role in the autonomic control of the respiratory and cardiovascular systems. Hypercapnoea, hypoxia or decreasing ph stimulate specialized cells in the carotid body to initiate an autonomic reflex which leads to increased respiratory rate and depth, increased heart rate, systemic vascular tone and blood pressure. Surgical excision of the tumour alone or with concomitant carotid artery resection is the mainstay of treatment [1].
