Surgical treatment of lesions of the facial nerve by an hypoglossal-facial anastomosis takes a long time to re-sprout of the nerve fibers to the facial muscles. The recovery time of facial function after surgical treatment of patients with paralysis of the facial nerve is long enough and can start from 6-8 months after surgery and last up to 2 years. Thus, all this time the mimic muscles are in a state of denervation.The purpose of this work was to determine the effect of electrical stimulation of facial muscles in patients with lesions of the facial nerve of different etiology after hypoglossal -facial anastomosis.Materials and methods: To evaluate the results of the use of early postoperative transcutaneus electrical stimulation, a low frequency FES was used, starting from the 2nd month after performing a XII-VII anastomosis. Assessment of the recovery of facial nerve function was performed 1 year after surgery. The study included 88 patients who underwent surgery to restore facial nerve function - hypoglossal -facial anastomosis. The survey was divided into 2 groups. The first (main) group consisted of 28 patients who underwent FES of facial muscles in the postoperative period, and the second group (comparison) consisted of 60 patients who underwent XII-VII anastomosis according to the following by the same method, but no further pharmacological or physiotherapeutic agents were used that could affect facial nerve regeneration.Results and discussion: According to this scale, the surveyed control group after 12 months. After the operation of XII-VII anastomosis according to the classical method, the following distribution was observed: The 1st degree of recovery of facial nerve function was not present in any of the patients, the 2nd degree had 2 (3.33%) patients, the thirds - 28 (46, 66%), IV - 20 (33,33%), V - 6 (10%) and VI - 4 (6,66%). In patients in the main group (where FES was used), distribution by degrees of recovery of facial nerve function on the House-Brackman scale after 12 months. after surgery it had the following character: II degree had 2 (6.45%) examined, III - 17 (54.83%), IV - 5 (22.58%), V - 2 (7.4%) and VI - 2 (7.4%).Conclusions: A statistically significant difference was observed in the postoperative period when comparing the mean M-responses of mimic muscles registered at different times after surgery in control subjects compared with patients in the main group in which FES was used. In addition, in the main group, a significantly larger number of patients reported a recovery of FN function to grade III-IV on the House-Brackman scale. Therefore, based on the results of the evaluation of the function of FN on the House-Brackman scale and electromyographic examination data in patients who underwent XII-VII anastomosis, it can be argued that with the use of FES in the postoperative period of recovery of facial nerve function is significantly faster and more complete in compared to the control group.
