The objective of this case study is to review Trigeminal schwannoma by observing 43 patients. TS or Trigeminal schwannomas are rare compared to vestibular schwannomas. The present study aims to analyze the clinical characteristics and surgical strategies of TS via the retrospective analysis of the clinical data of 43 patients. The clinical information of 43 patients diagnosed with TS who were surgically treated in the hospital by the doctors between January 2008 and January 2018. After the complete analysis, they discussed the selection of approaches and surgical strategies.

During the last ten years, 43 patients with TS received surgical treatment at Xuan Wu Hospital of Capital Medical University. Facial numbness and hypoesthesia were the most common symptoms developed in 29 cases (67.4%). Typical trigeminal neuralgia was complained by four patients (9.3%), while trigeminal motor impairment was set in nine cases. This percentage is around 20.9%. The surgeons obliterated the tumor from 39 patients (90.7%), near-totally removed in three patients (7.0%), and partially removed in one patient (2.3%) due to intraoperative internal carotid artery (ICA) injury. The abducens was intraoperatively damaged in two patients i.e. 4.7%. After the operation, all four patients with trigeminal neuralgia achieved total recovery, but the facial numbness continued in 24 patients. At a median of 45.3 ± 25.5 (6–84) months of follow-up, a tumor recurred in only one patient, and this patient received a second operation.
