AIM: To evaluate the role of botulinum toxin type A in the acute phase of facial nerve injury after neurosurgical surgery.
MATERIALS AND METHODS: The study involved 55 patients with acute facial muscle paresis caused by facial nerve injury during surgery on the posterior cranial fossa and cerebello-pontine angle (CPA). The first group consisted of 35 patients (mean age, 48.14±1.26 years) who were administered botulinum toxin type A (xeomin) at a dose of 2-3 U per point in muscles of the intact side of the face. The control group included 20 patients (mean age, 49.85±1.4 years) who underwent standard rehabilitation treatment of this pathology. The treatment efficacy was evaluated using the House-Brackmann Scale, the Yanagihara facial grading system, the Facial Disability Index (FDI), and the Sunnybrook Facial Grading (SFG) Scale.
RESULTS: Before treatment, patients of both groups experienced severe dysfunction according to the House-Brackmann Scale. A month after the botulinium toxin type A therapy had been started, a significant improvement in the group of patients who received botulinum toxin was observed at all scales (p<0.05), whereas improvement in the facial nerve function in the second group was observed only by the 3rd month of rehabilitation treatment (p<0.05). The number of synkineses in the patients who did not receive botulinum toxin was 46% higher than that in the first group (p=0.019) one year after the surgery, and it was higher by 91% after 2 years (p<0.001).
CONCLUSIONS: The use of botulinum toxin type A is reasonable in acute facial nerve injury and should be mandatory in combined therapy of these patients.
