title: Surgical management of carotid body tumors: a 15-year single institution experience employing an interdisciplinary approach.
abstract: Cervical paragangliomas are rare neoplasms that arise from extraadrenal paraganglia in close association with the cranial nerves and extracranial arterial system of the head and neck, and therefore surgical extirpation can be challenging. A retrospective study was conducted of all patients undergoing surgical excision of a cervical paraganglioma between 2000 and 2015. The demographic characteristics, clinical features, surgical approach, and outcomes were reviewed. A total of 20 cervical paragangliomas were excised in 17 patients. There were 14 female and 3 male patients with a mean age of 56.6 ± 17.0 at the time of operation. Twelve patients had unilateral tumors and 5 patients had bilateral tumors. Familial involvement was confirmed by history or direct genetic analysis in 8 (47%) of the 17 patients. There were no malignant paragangliomas, and only 3 patients had tumors that were determined to be functional. Tumor size ranged from 1.3 to 6.0 cm. Two patients required combined arterial resection as part of complete excision of the tumor. There were no permanent operative cranial nerve injuries, no recurrences, minimal morbidity, and no mortality. In conclusion, optimal management of cervical paragangliomas should include a thorough preoperative evaluation, accurate definition of the surgical anatomy, and exclusion of synchronous paragangliomas. A combined therapeutic approach by a multidisciplinary team including surgeons and interventional radiologists provides safe and effective management of cervical paragangliomas with very low morbidity and excellent outcomes.
