Frigeni B, et al. - Researchers conducted this prospective observational study to evaluate the role of neurophysiological preoperative and intraoperative parameters in providing prognostic information regarding facial nerve (FN) function at 1 year after translabyrinthine acoustic neuroma (AN) resection surgery. Between December 2015 and 2018, patients (n = 62; mean age was 53 ± 10 years and average tumor diameter was 23 ± 9 mm) treated by translabyrinthine surgical approach for sporadic AN microresection were included. At 1 year postoperative, preoperative pathological BR testing and A-train activity on intraoperative electromyography are associated with poor FN outcomes. It can provide important prognostic knowledge both for patients and for neuro-otologists. This can guide preoperative and postoperative therapy of patients in the future, and probably improve the timing of facial nerve reanimation in selected patients.
