[The effect of autogenous vein cuff and injection of cerebral cell growth peptide on the recovery of injured facial nerve].

OBJECTIVE

To study the effect of autogenous vein cuff and injection of cerebral cell growth peptide on the recovery of the injured facial nerve.

METHODS

The injured facial nerve was anastomosed and covered with an autogenous vein cuff. Cerebral cell growth peptide was then injected to it. The different repairing methods were evaluated and compared with electromyography and observing functional recovery of the mimetic muscles.

RESULTS

The new repairing method accelerated the recovery of the injured facial nerve. The recovery period of mimetic muscle function was significant shorter than the traditional method (P < 0.01). The recovery period of I-stage repairing was significant shorter than that of II--stage repairing (P < 0.01). The conduction velocity of the repaired facial nerves had no obvious differences between the new repairing method and the traditional method (P > 0.05).

CONCLUSION

Application of the autogenous vein cuff to cover the nerve anastomosis and injection of cerebral cell growth peptide is a promising method for facial nerve repairing.
