Temporal bone findings in a case of amyloidosis with hearing loss and vertigo are reported. The striking findings of the bilateral temporal bones were amyloid deposits observed in the facial nerve. To our knowledge, there are no cases with amyloid deposits in the temporal bones among amyloidosis cases reported in the literature. Dehiscence of the facial canal and the facial nerve protruding on to the stapes was observed bilaterally. Inflammation with ossification in the posterior semicircular canal and reduction in the number of spiral ganglion cells were observed in the left ear.
