Abstract:
In the study, X—ray, patholoSy and electron neuro—physiology were used for obsering the injury of facial nerve. The result revealed that the microstructure of the facial nerve was damaged while the macrostructure unchansed. The microstructure changes included: fibre broken—up, bleeding in perineurium, deformation of axon, mitochondria swelling. Nerve evoking potential examination indicated that the latency was prolonsed, amplitude decreased and nerve conduction velocity was delayed. This results showed that there existed indired nerve injury. It is important to relieve the intraneural pressure, recover microcirculation and remove heamatoma in muscle and fascia in early stage
