Preoperative Radiological Features Predict Facial and Cochlear Nerve Function after Vestibular Schwannoma Surgery: A Single-Center Retrospective Study

Vestibular schwannoma (VS) surgery carries risks of facial nerve (FN) dysfunction and hearing loss. This study aimed to identify preoperative radiological predictors of postoperative FN function and develop a predictive nomogram.

Preoperative imaging features may help predict nerve outcomes after vestibular schwannoma surgery, but retrospective single-center data warrant cautious interpretation before changing surgical planning or counseling protocols.

Identifying reliable preoperative imaging predictors of nerve function could improve patient counseling and surgical decision-making for vestibular schwannoma, where facial paralysis and hearing loss are significant surgical risks.
