Carotid Body Tumour Excision

Carotid Body Tumor (CBT) excision is a surgical procedure to remove a tumor located at the carotid body, a small cluster of chemoreceptor cells situated at the bifurcation (fork) of the carotid artery in the neck. The carotid body monitors oxygen levels in the blood, and a tumor in this area, known as a carotid body tumor or paraganglioma, can disrupt normal blood flow, compress nearby structures, and lead to symptoms.

What is a Carotid Body Tumor?

Carotid body tumors are rare, typically benign (non-cancerous) growths, although they can sometimes be malignant. They usually grow slowly but can reach a size that causes symptoms such as difficulty swallowing, voice changes, pain, or visible swelling in the neck. These tumors are also referred to as paragangliomas, as they originate from paraganglia cells involved in regulating blood oxygen.

Indications for Carotid Body Tumor Excision

Surgical excision of a carotid body tumor is typically recommended if:

• The tumor is growing or causing symptoms, such as pain, difficulty breathing, swallowing issues, or hoarseness.
• There is a risk of malignancy (although rare) or the tumor poses a threat to surrounding structures.
• Increased blood flow risk, as the tumor can sometimes connect to the carotid artery, increasing the risk of vascular complications.

Benefits

Carotid body tumor excision offers several significant benefits, especially when the tumor is causing symptoms or poses potential health risks. Key benefits include:

• Symptom Relief: Removal of the tumor alleviates symptoms like neck swelling, pain, difficulty swallowing, and hoarseness, improving the patient’s comfort and quality of life.
• Reduced Risk of Malignancy Spread: Although carotid body tumors are often benign, there is a small chance of malignancy. Excision reduces the risk of local or distant spread if the tumor has cancerous potential.
• Improved Blood Flow and Vascular Health: Tumors near the carotid artery can disrupt blood flow, potentially leading to vascular issues or increased blood pressure. Excision restores normal blood flow and reduces vascular strain.
• Long-Term Health Improvement: Excision lowers the risk of recurrent symptoms and ongoing monitoring, offering a lasting solution and allowing patients to focus on other aspects of health and well-being.
