Objective: Surgery for vestibular schwannoma (VS), located in the cerebellopontine angle, presents a significant neurosurgical challenge due to the tumor’s proximity to cranial nerves and critical neural and vascular structures. This study aimed to evaluate the efficacy and safety of combining intraoperative neuronavigation (NN) and neuromonitoring (NM) in the resection of VS tumors. Methods: We retrospectively reviewed the medical records of patients who underwent VS tumor resection at our center between 2018 and 2023. Patients were divided into two groups: those who underwent surgery with NN and NM guidance (nVS group) and those who underwent surgery without these techniques (pVS group). The groups were compared with respect to cranial nerve identification, preservation of facial nerve function, advantages and limitations of NN and NM systems, and extent of tumor resection. Results: In the pVS group, intraoperative visualization of the facial nerve was not achieved in seven patients (46.7%). Conversely, all patients in the nVS group had their facial nerves successfully identified intraoperatively (p<0.001). Postoperative evaluation revealed worsening facial nerve function, as measured by the House-Brackmann scale, in seven (46.7%) patients in the pVS group compared with two (16.7%) patients in the nVS group (p<0.001). The median time from anesthesia induction to surgery commencement was significantly shorter in the pVS group (p<0.001). Conclusion: The combined use of NN and NM enhances tumor margin identification and adjacent structure visualization during surgery. Additionally, it facilitates real-time monitoring of neurological functions, contributing to improved surgical outcomes and reduced risk of postoperative complications.
