AbstractPurposeFacial nerve monitoring can be used to predict post-operative facial function after skull base surgery. In this study three methods of prediction of facial function were compared. These methods utilize various parameters of the evoked electromyographic monitoring.Material and methodsTwenty-three patients who underwent surgery for skull base diseases were retrospectively reviewed. Amplitude of ongoing electromyographic activity, stimulation current thresholds and amplitude of evoked response were analysed. The predictive value of the three methods was correlated with post-operative facial nerve function.ResultsThe method that used only the stimulation thresholds predicted the final post-operative facial function in 86.9 per cent of the patients. The second employed a mathematical ratio which combined the amplitude of evoked response and the stimulation current thresholds and confirmed the prediction of the facial function in 91.3 per cent of the patients. The last method does not consider the stimulation thresholds greater than 0.05 mA and failed to predict the final VIIth nerve function in patients in whom the stimulation was greater than 0.05 mA.ConclusionAnalysis of prognostic value demonstrates that the first two methods had the smaller degree of variation showing the better sensitivity.

AbstractIntraoperative facial nerve monitoring has become an integral adjunct in facial nerve identification and preservation for patients undergoing cerebellopontine angle surgery. Since the first description of EMG monitoring of facial nerve activity intraoperatively, many systems have been developed. These systems often rely on unilateral monitoring of the facial nerve with auditory feedback to the surgeon, and it is difficult to distinguish between artifact and significant stimulation of the facial nerve.In this paper, we present the use of a bilateral, multialarm, facial nerve monitoring system that has multiple advantages over previous systems. Furthermore, we review our experience with this bilateral system, comparing a group of 50 monitored patients to a group of 50 unmonitored patients.

AbstractThe purpose of this work was to compare pre- and post-operative facial nerve function between unmonitored and monitored cases of skull base lesions. The study involved 32 patients suffering from lateral skull base tumours (10 unmonitored and 22 monitored). Facial nerve function was monitored intraoperatively by an acoustic facial electromyographic system (NIM-2). Post-operative facial function was graded according to the House-Brackmann scale. In the group of monitored cases, facial nerve function was normal (Grade 1 or 2) in 79 per cent of the patients, while the unmonitored patients showed normal function in only 50 per cent of the cases.These results confirm previous observations that audible evoked electromyographic monitoring significantly reduces permanent facial nerve dysfunction.
