Congenital duplication of mastoid segment of facial nerve: A rare case report

Abstract: Congenital duplication of facial nerve is a very rare anomaly commonly associated with inner and middle ear anomalies. There can be duplication of mastoid, tympanic, or labyrinthine segments. We describe duplication of mastoid segment of facial nerve in a young female who also showed middle ear anomalies and external auditory canal atresia.

“…The nerve may course with bifurcation, trifurcation or other aberrant pathways within the temporal bone. Bifurcation of the facial nerve is a rare variant with focal splitting of one or more segments [ 15 , 16 ]. The mastoid segment of the nerve runs in a line starting from fossa incudis where short process of incus lies to anterior end of the digastric ridge.…”
