Complications associated with carotid body tumor excision.

BACKGROUND

This study aims to evaluate associated complications of carotid tumor excisions and outcomes.

METHODS

Between January 2013 and April 2016, a total of 29 patients (2 males, 27 females; mean age 55.2±4.4 years; range, 17 to 76 years) were operated with the preliminary diagnosis of a carotid body tumor. According to the Shamblin classification of carotid body tumors, 12 patients were type 1, 13 patients were type 2, and four patients were type 3.

RESULTS

Main symptoms were dizziness, pain in the neck area, tinnitus, and headache. Headache was the most common symptom among them. Neurological and surgical complications developed in 10 patients (34.4%). Of operated patients, dysphagia developed in three (8.7%), facial hemiparesis in two (6.8%), hemorrhage in two (6.8%), hematoma-related respiratory distress in one (3.4%), left hemiparesis in one (3.4%), and transient bradycardia in one (3.4%). The patient who had respiratory distress associated with bleeding following extubation was reoperated. In the patients with facial and left hemiparesis, paresis was transient. Dysphagia also resolved in the subsequent follow-up outpatient visits. None of the patients experienced a permanent complication.

CONCLUSION

Surgical excision is the most appropriate choice of treatment in carotid body tumors, and postoperative complications can be minimized through careful dissections and retractions. A special attention should be paid to nerve-preserving surgery.
