Carotid body tumor: Surgical management and complications

Abstract

Introduction: Carotid body tumors (CBT) or paragangliomas account for approximately 3% of all paragangliomas occurring in the head-and-neck region. Delay in the surgical resection of tumors may be associated with high morbidity or mortality and risk of malignant transformation. Methodology: Three cases of CBTs were included in the study, out of which one case presented as bilateral neck swelling. All the patients were clinically and radiologically evaluated and taken up for surgical excision of the tumor. In case with bilateral tumor, a staged removal was planned. Results: Out of three patients, a female patient developed stroke postoperatively, she was managed and discharged in stable condition, and another male patient developed left vagal palsy. Conclusion: Excision of shambling Type III CBTs is difficult and one should know the collateral circulation of the tumor preoperatively. Bilateral CBT resection requires staging procedures to reduce the risk of cardiovascular and neurological issues.
