To derive and validate a scoring system predicting facial nerve outcomes after vestibular schwannoma resection.
Retrospective cohort study of patients undergoing vestibular schwannoma surgery from 2016 to 2024.
Developed a scoring system using multivariable logistic regression for predicting facial nerve outcomes.
External validation included analysis at Stanford Healthcare and University of Cincinnati Medical Center.
22% of patients experienced poor facial nerve outcome post-surgery.
The acoustic neuroma 7 score showed superior predictive accuracy compared to the Facial Nerve Outcome Score.
External validation revealed favorable calibration for the acoustic neuroma 7 model.
