Overview

Surgery is the mainstay of treatment for the carotid body tumor.

Surgery

Surgery is the treatment of choice for carotid body tumor.

• Surgical approach of the tumor is different for each Shamblin subclassification:
  • For Shamblin type I/II case without an abundant blood supply, simple resection of the tumor is the optimal treatment.
  • For Shamblin type III cases with large tumors and malignant tumors involving important peripheral vessels resection and reconstructive vascular operation (including simple vascular anastomosis, internal carotid artery-common carotid artery artificial and autologous reconstructive vascular operation) is appropriate.

Contraindications

• Individual who are poor candidates of surgery due to any reason.

Complications of surgery

• Surgical excision of the tumor may be complicated by:
  • Cranial nerve involvement in 10% to 56% of the cases.
  • The most commonly involved nerves are such as:
    • The hypoglossal nerve
    • The superior laryngeal nerve
    • The vagus nerve,
    • The mandibular branch of the facial nerve
    • The pharyngeal branch of the vagus nerve
    • The glossopharyngeal nerve
    • The spinal accessory nerve
    • The sympathetic chain
