Clinical and experimental study on facial paralysis in temporal bone fracture.
OBJECTIVE
To study the main prognostic factors and significance of facial nerve decompression for facial paralysis in temporal bone fracture.


METHODS
The main relative prognostic factors of 64 patients with facial paralysis were analyzed. An experimental model of facial paralysis was made. The expansion rates of facial nerve in the facial canal opening group and the facial canal non-opening group were measured and observed under electron microscope.


RESULTS
The main factors affecting the prognosis were facial nerve decompression and selection of surgery time. The expansion rate of facial nerve in the facial canal opening group was significantly higher than that of the facial canal non-opening group (t=7.53, P<0.01). The injury degree of the nerve fiber in the facial canal non-opening group was severe.


CONCLUSIONS
Early facial nerve decompression is beneficial to restoration of the facial nerve function.
