OBJECTIVE Classical surgical management of jugular foramen (JF) tumors usually requires facial nerve rerouting which results in permanent facial palsy in most patients. The purpose of the article is to study the outcomes of different rerouting techniques, and to discuss their indications. MATERIAL AND METHODS We retrospectively reviewed 98 patients with JF tumors operated at our center between January 2008 and December 2016 using different surgical approaches with the following procedures for facial nerve management: total anterior rerouting (TR), partial anterior rerouting (PR), and fallopian bridge (FB) technique. The data for facial nerve management, surgical outcome and postoperative facial nerve function were collected from the medical records. RESULTS In the study, there were 48 males and 50 females. Of them, 61 (62.2%) were jugular paragangliomas, 22 (22.4%) schwannomas, and 15 (15.3%) meningiomas. Total tumor removal was achieved in 95 (96.9%) patients, while near-total removal was achieved in 3 (3.1%) paragangliomas. TR was applied in 31 (31.6%) patients with PR in 26 (26.5%) patients, and FB in 41 (41.8%) patients. The mean follow-up duration was 39.4±22.6 months, and 2 recurrences of paragangliomas were observed. Seventy-five patients (76.5%) had good facial function (HB I-II) at 1 year after surgery, the patients who received a TR approach presented significantly less HB I-II FN function (48.4%) than those with PR (82.6%, P<0.05) or those with FB technique (95.1%, P<0.001). 21 patients (21.4%) presented new-onset lower cranial nerve dysfunction of which 13 recovered at 1 year after surgery. CONCLUSION Facial nerve management in JF tumors should be tailored individually. No-rerouting methods, such as the fallopian bridge technique, bring significantly better results in terms of facial nerve function, which might be performed first during surgery; its indication is based mainly on the tumor type and extent.
