Summary
Carotid body paragangliomas (CBP) are rare neck tumors. Surgical removal requires careful technique to minimize risks like nerve damage, as demonstrated in this study of 5 patients.
Area of Science:
- Otolaryngology
- Neurosurgery
- Vascular Surgery
Background:
- Carotid body paragangliomas (CBP) are rare neoplasms originating from the carotid bifurcation chemoreceptor.
- Diagnosis and management of CBP present unique surgical challenges due to proximity to vital neurovascular structures.
Purpose of the Study:
- To present the diagnostic process, treatment, and outcomes for patients with carotid body paragangliomas.
- To analyze the surgical management and complications associated with CBP excision.
Main Methods:
- Retrospective analysis of 5 patients (3 female, 2 male; age 44-68) with CBP treated between 1997-2008.
- Utilized physical examination, color duplex ultrasonography, CT, MRI, and digital subtraction angiography for diagnosis.
- Surgical excision performed with blunt dissection in the subadventitial plane for Shamblin type I and II tumors.
Main Results:
- The most common symptom was a nonspecific neck mass.
- Four patients had Shamblin type II tumors, and one had a Shamblin type I tumor.
- One patient experienced postoperative vagus and hypoglossal nerve deficits.
Conclusions:
- Carotid body paraganglioma excision carries risks of cranial nerve paresis and carotid artery injury.
- Careful surgical handling and skilled technique are essential for complete tumor removal and minimizing complications.
