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.

Discussion
Signed responses from readers of the wire.
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.

- 02Preoperative MRI/CT features were assessed as predictors of post-surgical facial and cochlear nerve outcomes.
- 03Findings could support pre-surgical risk stratification for vestibular schwannoma patients.
- 04Retrospective single-center design limits generalizability.
- 05Cochlear nerve preservation is directly relevant to candidacy for cochlear implantation post-surgery.
Specific preoperative radiological features can predict facial nerve function after vestibular schwannoma surgery.
