Blink Reflex for Facial Nerve Monitoring: A Feasibility Study

Background: Facial nerve preservation remains a challenge during cerebellopontine angle (CPA) surgery, especially vestibular schwannoma resection. The reliability of using the blink reflex to guide surgical resection and its prognostic role in facial nerve outcomes remains uncertain. In this study, we assess the feasibility of using blink reflex for intraoperative facial nerve monitoring in patients undergoing translabyrinthine resection of vestibular schwannomas.
