Ectopic striated muscle in the fallopian canal: a histopathologic report.
Two temporal bones are discussed that contain ectopic striated muscle in the horizontal fallopian canal. In one instance, this muscle was clearly innervated by a branch from the geniculate ganglion. This is an unusual histologic finding and the innervation to such a muscle has been rarely identified. The facial nerve surgeon should be aware that a mass encountered during decompression may be developmental rather than neoplastic.
