Özet: Objectives: In this study, we present our surgical experience for carotid body tumors (CBT), which are rare neoplasms arising from the paraganglion cells. Patients and methods: Between January 2000 and December 2009, a total of 12 patients with CBT (4 males, 8 females; mean age 50.3±8.4 years; range, 35 to 70 years) who underwent surgical excision in our clinic were retrospectively analyzed. Magnetic resonance imaging was used for the diagnosis. The patients were evaluated in terms of clinical and operative parameters, and postoperative complications. Results: The mean follow-up was 7.5 years. One of the patients was operated bilaterally after two years. Three patients underwent endovascular embolization before surgery. As our standard procedure, the tumor was dissected from the carotid artery subadventitially, while three patients underwent internal carotid artery (ICA) revascularization due to ICA invasion. The external carotid artery (ECA) was also ligated in three patients. Lymph node dissection was performed in two patients. However, pathology result was reported as a reactive lymph node. None of the patients received radiotherapy. Left hemiplegia occurred in one patient after surgery, and the same patient died at the third year due to a non-surgical cause. No recurrences or major complications were seen during follow-up of other patients. Conclusion: The definitive treatment of KCTs which are clinically considered malignant due to their localization is surgical excision. The ICA and ECA ligation may be required in the advanced stages of tumors. However, ICA revascularization has a vital importance in these patients. In addition, utmost meticulousness is required to avoid nerve and vessel injuries during surgery. Although recurrent lesions have been reported in these patients, long-term results are satisfactory.
