Objective: To Preliminary study of facial nerve F wave evaluation hypoglossal-facial nerve reconstruction with pre-degenerated nerve graft for peripheral facial palsy.
Methods: The clinical data were retrospectively reviewed for 30 patients with peripheral facial palsy after cerebellontine angle underwent nerve anastomosis were analyzed between November 2011 and February 2014. F wave and M wave detection were used to evaluate the pre-, post-opertive and status.The hypoglossal-facial nerve by "side- to-side" anastomisis was performed.
Results: All patients were followed-up.The mean time of follow-up was 8 months (ranged from 3 to 20 months). 12 patients were found a higher recovery of facial nerve function after the nerve anastomosis.16 patients who F wave of post-opertive were found a higher recovery compared to F wave of pre-opertive (P < 0.05).
Conclusion: The hypoglossal-facial nerve by "side"-to-side anastomisis with pre-degenerated auto-nerve graft was effective for the treatment of peripheral facial palsy after CPA tumor resection, F wave can be used as one of the objective index for the effect of the operation.
