Background: Surgical removal of a tumor that has grown together with the perineural membrane of the nerves and their smaller branches in the face and neck region often leads to their damage. In order to reduce the risk of nerve damage, intraoperative neurophysiological monitoring (IONM) can be used. Purpose: to develop a simple identification technology and visual monitoring that does not need a large number of needle electrodes providing its use without regular electrophysiologist’s control and help.
Material and methods: neuroplastic surgery was performed in 120 patients with facial muscles paralysis after removal of the bridge-cerebellar corner neuroma with subsequent facial nerve damage, in order to restore innervation. The original technology of identification and monitoring of nerves and muscles functional state was used during operations. It was based on the electrical stimulation tests and visual observation of muscle contractions — intraoperative visual neuromonitoring (IOVNM), with polyprogram electrostimulator specially developed for that. The entire procedure — the control over the electrostimulator, testing programs choice, their launch, visual observation and the IOVNM — was carried out just by the operating surgeon.Results: The application of the IOVNM technology on all stages of surgical intervention significantly facilitated the assessment of nerves condition and fastened the choice of reinnervation method. The duration of such operation was reduced by 50–70 minutes compared to the one without its use. Conclusion: The use of IOVNM can optimize the operation scheme and reduce its duration.
