Comparison of surgical outcomes between early and advanced class of jugular paragangliomas following application of our modified surgical techniques

Abstract

AbstractTo compare the safety and effectiveness of surgical treatment of jugular paragangliomas (JPs) following the application of our modified surgical techniques. Fifty-six patients with JPs were analyzed for tumor classification, surgical outcomes, and intratumor blood vessels. The gross total resection in C1–2 (100%) was significantly greater than that in C3 and D (66.7%). Good postoperative facial nerve (FN) function (House–Brackmann I–II) was achieved in 89.5% C1–2 cases, which was not significantly different from C3 and D (93.3%) (P = 0.694). Preoperative and postoperative lower cranial nerve (LCN) deficits correlated with the Fisch’s classification of tumors (P < 0.05), and intraoperative blood loss was greater in advanced tumors (P = 0.050). Further study showed that the cross-sectional area of intratumor blood vessels was positively associated with intraoperative blood loss (P < 0.001). Surgical excision of JPs is a safe and effective strategy, and early surgical treatment is a good option for patients with C1–2 tumors without surgical contraindications.
