A forty-one-year-old man presented with right-sided
progressive facial nerve paralysis of one year duration.
Computed tomography of the temporal bone
showed a soft tissue mass in relation with the tympanic
segment of the facial nerve with destructive
changes in the facial recess region. Magnetic resonance
images before and after gadolinium injection
revealed a contrast-enhancing mass lesion in the
tympanic cavity. The tumor was removed through a
transmastoid approach and a cable graft from the
greater auricular nerve was used to repair the defect.
Histopathologic diagnosis was facial nerve schwannoma.
At the end of one-year follow-up, the patient
had moderately severe facial nerve dysfunction.
