Diagnosis and surgical treatment of carotid body tumor: A retrospective analysis of 58 patients.

The aim of the present study was to illustrate the diagnosis and treatment of carotid body tumor (CBT) based on our experience of previous patients. A total of 58 patients (62 lesions) with CBT who received surgery between October 2003 and October 2013 were included. In total, 17 lesions were categorized into Shamblin grade I, 33 were grade II, and 12 were grade III. Surgical resection of CBT was performed for 52 lesions, resection of CBT and the external carotid artery was performed for 9 lesions, and resection of CBT and the internal carotid artery was performed for 1 lesion. No hemiplegia was observed. Hoarseness and bucking were observed in 2 patients of Shamblin grade III, and were eliminated 1 month subsequent to the administration of hormone therapy and a nerve-nurturing strategy. No relapse or mortality was observed during the follow-up. In conclusion, surgical resection of CBT is recommended following diagnosis. The evaluation of imaging features and cerebral collateral circulation is important for treatment.
