Background
The aim of the present study was to review the contemporary presentation and evolution of management of neck paragangliomas.Methods
Forty-one neck paragangliomas operated on in 36 patients over a 44 year period were included in the current report. The study period was divided into two parts, the first three decades (1964-1989), during which the current management techniques were evolved, and the last two decades (1990-2008).
Results
Patients presented with a palpable neck mass (n = 17), cranial nerve (CN) palsy (n = 3) or both (n = 6), or the lesion was an incidental finding (n = 14). The use of cross-section imaging modalities (n = 24) increased from 35 % during the first part of the study to 95 % during the second part of the study (P < .001). Preoperative embolization (introduced in 1979) was performed in 60 % (median size 4.3 cm for embolized vs 3 cm [P = .02], for non-embolized tumors). During the first study period, the frequency of Shamblin group II/III tumors was 95 % compared with a frequency of 42 % during the second study period (P < .001, odds ratio 25), median blood loss was 600 ml and 150 ml, respectively (P = .001) and the transfusion rate was 44 % and 5 % , respectively (P = .008). The incidence of temporary and permanent new CN deficits postoperatively was 22.5 % and 10 % , respectively, and was similar during the two study periods. Three tumors were malignant, based on lymph node involvement (n = 1) or development of late metastases (n = 2).
Conclusions
In the modern era, neck paragangliomas can be managed with a low incidence of long-term sequelae. Smaller, asymptomatic, and incidentally detected tumors are currently the most common presentation pattern.
