At the January meeting of the Southern Section of the Triological Society held in Birmingham, Ala, Thomas Eby, Anita Pollack, and Ugo Fisch presented a case report describing temporal bone findings in a patient with facial nerve paralysis secondary to longitudinal and transverse temporal bone fractures. The patient was an epileptic who had suffered multiple head injuries during his life and, on several occasions, had associated facial nerve paresis. He died of other causes about 18 months following facial nerve decompression for one of his injuries. The authors reviewed temporal bone fractures and their association with facial nerve paralysis. They noted that transverse fractures, although they occur less commonly than longitudinal fractures, are more likely to have associated facial nerve paralysis. In longitudinal fractures the injury is most commonly noted near the area of the geniculate ganglion, and the mechanism seems to be one of traction rather than complete severance.
