Operative approaches consisted of translabyrinthine (50.8%), retrosigmoid (25.0%), and middle fossa craniotomies (24.2%). Extent of resection was decided intraoperatively, and gross or near total resection was accomplished in 237 (92.6%) cases. Postoperative HB grade correlated with latest HB grade (0.615, <jats:italic>P<\/jats:italic> &lt;. 001). Factors associated with good postoperative FN function included small tumor size (\u226415\u00a0mm; odds ratio [OR], 2.425; <jats:italic>P<\/jats:italic> =. 042), gross or near total resection (OR, 3.170; <jats:italic>P<\/jats:italic> =. 041), and \u2265100\u2010\u00b5V intraoperative FN electromyographic response to a 0.05\u2010mA stimulus (OR, 22.242; <jats:italic>P<\/jats:italic> &lt;. 001).
