  • Abstract
  • Look Inside

We developed a Micro-neurostimulator that is suitable for intracranial electrical stimulation of the facial nerve in excision of acoustic neurinomas. The tips of our Mic-ro-neurostimulator were thinner and finer than those of commercially-available bipolar forceps and therefore it was possible to stimulate tumor tissue and the facial nerve selectively. This facilitated precise excision of tumor tissue from the facial nerve without residual tumor tissue around it.

It was emphasized that the shape of the tips of stimu-lating electrodes and the stimulus intensity were the most important factors in obtaining reliable responses in preserving the facial nerve using intracranial electrical stimulation and evoked electromyographic responses.
