    Facial
    Nerve Injury in Congenital Aural
    Atresia Surgery.

    Am J Otol 19:283-287, 1998.

        

    Fear of injury to the facial
    nerve is a great deterrent to
    atresia surgery.
    Data on more than 1000
    patients who underwent surgery
    for congenital aural atresia,
    were retrospectively reviewed.
    Ten patients sustained a
    facial nerve injury during
    atresia surgery.

        

    The facial nerve is displaced in
    25% to 30% patients with
    congenital aural atresia.
    For less experienced
    surgeons, the facial nerve is at
    greatest risk in the
    inferoposterior part of atretic
    bone, just lateral to the middle
    ear.
    For more experienced
    surgeons, patients with low-set
    ears canal stenosis and an
    accompanying cholesteratome are
    at risk for facial nerve injury.

    Hemifacial
    Spasm Caused by Vascular
    Compression of the Distal
    Portion of the Facial Nerve:
    Report of Seven Cases.

    J Neurosurg 88:605-609, 1998.

        

    In a recent series of 142
    patients with Hemifacial Spasm (HFS),
    5% (7 patients) were found to
    have compression of a distal
    portion of the seventh cranial
    nerve combined with compression
    at its root-entry zones (REZ) or
    compression of a distal portion
    of the nerve alone.

        

    In all 7 patients, vascular
    compression distal to the REZ of
    the facial nerve caused HFS.
    symptoms
    resolved when neurovascular
    decompression was performed at
    these sites.

        

    Although the REZ is the primary
    site of vascular compression
    causing HFS in most cases, in
    these 7 cases compressed sites
    were definitely NOT at the REZs.
