The time course of electrical reactions in this condition varied much from that after section of the facial nerve or after Bell's palsy. It was at least a week before denervation could be suspected in the latter conditions by electrodiagnostic methods. In post-traumatic delayed facial palsy we have demonstrated electrical reactions showing denervation at the time of palsy or even a few days before, and this is probably related to its pathogenesis. Denervation occurred in 82% of cases which is about double the incidence in Bell's palsy.
在这种情况下，电反应的时间进程与面神经切断术后或贝尔面瘫后的情况有很大不同。在后一种情况下，通过电诊断方法至少要一周后才能怀疑有失神经支配。在创伤后迟发性面瘫中，我们已经证明在面瘫时甚至在面瘫前几天就出现了显示失神经支配的电反应，这可能与其发病机制有关。82%的病例发生了失神经支配，这大约是贝尔面瘫发病率的两倍。
