SIMKIN, David O. et al. Cervical paragangliomas. Comparison of current results with historical series. Rev. argent. cir. [online]. 2014, vol.106, n.1, pp.1-10. ISSN 2250-639X.

Background: cervical paragangliomas are very rare tumours and receive diferent names according to the site of origin. Carotd for those localized in the carotd bifurcaton, tympanic for those in the middle ear, yugular for those in the yugular bulb and vagal for those in the vagal nerve. Setng: tertary care oncologic public hospita. Populaton: 26 patents, 22 of them surgically treated. Mean age was 48.6 years, 77% female. Methods: review of clinical records and pathologic reports. Results: twelve were at the lef side, 11 at the right, 2 bilateral and 1 multple. Diagnosis was done by semiology, magnetic resonance and computed tomography. The tumors were classifed according to Shamblin classificaton in 1, 2 grades in 16 patents and 3 in 10. Surgery included tumor resecton with vascular graf in 2, XI and XII craneal nerve also in 2, while 4 patents remained in observaton because they were asymptomatic. Morbidity was 22.7%, sequels 31.8% and mortality 4.5%, diferent to the historic series with 44.4%, 55.5% and 5.4% respectvely. Conclusions: tumors of carotd body are infrequent, benign and of slow growth. Diagnostic techniques frequently used were ecodopler, CT scan and MRI, with positve results in about 100% of cases. It was diferent to historic series in which angiographic studies had positve results in only 70% of them. Symptomatic Shamblin 1, 2 and 3 were surgically treated with 31.8% of sequels, diferent to historic sample with 55.5%, but in asymptomatic grade 3, careful selecton of patents must be taken into ac-count for avoiding an aggressive surgery with high morbidity. This conclusion is diferent of the historic series in which all patents were surgically treated.
