Methods: Forty-two patients with severe nerve damage were analyzed for clinical manifestations. Nerve conduction test and EMG examination were completed and it,s results were comparted with their clinical effectiveness in all cases at 1month, 3months,6months,respectively. Results: In the 42 patients with idiopathic facial palsy after severe nerve damage: ⑴ There was no improvement in neural function recovery after therapy（P﹥0.05） ; otor nerve conduction velocity slowed, the latency prolonged ,the M wave amplitude decreased for 70% than that of normal person, and denervated potential within the muscles innervated by the facial nerve on the ill side was detected, the results of the above 4 parameters in the treatment of 1, 3 and 6 months compared with normal have significant difference（ P﹤0.01）.But different time before and after treatment had no significant change (P ﹥ 0.05).Conclusions: For patients with idiopathic
