[Preliminary study of facial nerve F wave evaluation hypoglossal-facial nerve reconstruction with predegenerated nerve graft for peripheral facial palsy].

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.
