Facial nerve preservation in vestibular in schwannoma surgery:—new surgical instrument : stimulus dissectors and scissors—

概要

Intra-operative monitoring for facial nerve function has been widely used in vestibular schwannoma surgery. We have devised new surgical instruments named "stimulus dissectors and scissors", which can be useful not only as a probe for facial nerve monitoring but also as a dissector and a scissor. In this report, we present how to use these new surgical instruments in actual surgical manipulation. Although only a few patients have so far undergone vestibular schwannoma surgery using these instruments, we have got several benefits as follows: 1) The operation time has become shorter because it doesn't need to switch the instrument, 2) the intracranial facial nerve anastomosis has become easier because the facial nerve can be easily identified with these instruments.<BR>The usefulness of the facial nerve monitoring in vestibular schwannoma surgery are also discussed with a review of literatures.
