  • Title: New aspects of facial nerve pathology in temporal bone fractures.
    Author: Felix H, Eby TL, Fisch U.
    Journal: Acta Otolaryngol; 1991; 111(2):332-6. PubMed ID: 2068919.
    Abstract:
    Electron microscopic examination of intratemporal facial nerve segments removed from 12 patients with persisting facial paralysis following temporal bone fractures revealed that traumatic injury at the geniculum induces retrograde degeneration through the labyrinthine and distal meatal segments of the facial nerve. Fibrosis may occur in the traumatized labyrinthine segment and block regenerating motor fibers. The surgical treatment of traumatic facial nerve injuries should be aimed to avoid or eliminate fibrosis within the labyrinthine segment of the Fallopian canal.
