Abstract
Introduction. When operating on the face and neck, a technology for intraoperatuve neurophysiological monitoring is used to ensure the right nerve function.
Aim. Development of a technology for the intraoperatuve neuromonitoring and a practical estimation of its efficiency in the reconstructive neuroplasty surgery.
Methods. In 120 patients with the paralysis of mimic muscles after the removal of a cerebellopontine angle neuroma and a facial nerve damage, neuroplasty was performed to restore the innervation. An original technique was developed for identification and monitoring of the functional state of the nerves and muscles intraoperative visual neuromonitoring (IOVNM). Its concept consists in electric stimulation of the nerves within the surgical field and visual observation of the response muscular contractions. A special ESVM-1 electric stimulator with a set of built-in test programs has been created. The control of the instrument, selection of tests, their launch, visual observation of the reactions and the intraoperative monitoring itself are performed by the operating surgeon.
Results. The presented technology eliminates the need for a complex equipment for neurophysiological monitoring and does not require the participation of a specialist in neurophysiology.
Conclusion. The use of IOVNM during the operation provides an opportunity to assess the functional state of the facial nerve and mimic muscles, to optimize the operation scheme and accelerate its implementation.
