    Journal: World Neurosurg; 2022 Feb; 158():189. PubMed ID: 34861446.
    Abstract:
    In vestibular schwannoma surgery, neuromonitoring is essential to accomplish sufficient tumor resection while avoiding neurologic damage.1-3 An ideal neuromonitoring method should include a real-time alert system, quantitative evaluation, and functional (not mechanical) assessment.4Video 1 demonstrates facial and hearing preservation surgery for vestibular schwannoma by the retrosigmoid transmeatal approach, under intraoperative continuous facial nerve monitoring and auditory brainstem response. Using a ball-type stimulating electrode placed on the proximal facial nerve, the evoked facial nerve electromyograms were continuously monitored by direct 1-Hz stimulation throughout the near-total tumor resection. The patient had no postoperative facial or hearing deterioration. The patient consented to the procedure before the surgery.
