The medium and long-term effect of electrophysiologic monitoring on the facial nerve function in minimally invasive surgery treating acoustic neuroma

Abstract

The medium and long-term effects of electrophysiologic monitoring on the facial nerve function in minimally invasive surgery treating acoustic neuroma were studied. Sixty-two patients with acoustic neuroma taking minimally invasive surgeries in Dezhou Hospital from August 2014 to September 2015 were selected and randomly divided into 29 cases of the control group and 33 cases of the observation group. Intraoperative electrophysiologic monitoring was applied to the observation group, but not to the control group. The effects of the surgeries were compared. Comparisons on the surgical resection rate and the surgery length between two groups showed no statistical differences (P>0.05); the anatomical and functional preservation rate of facial nerves, as well as the score of survival quality in the observation group prominently proceeded that in the control group, and the differences were statistically significant (P>0.05). In conclusion, the application of the electrophysiologic monitoring on facial nerve function in minimally invasive surgery treating acoustic neuroma can effectively increase the anatomical and functional preservation rate of facial nerves, providing certain clinical significance to the improvement of living quality.
