Abstract:
Schwannomas are slow-growing, benign neurogenic tumors arising from schwann cells. Their localization in the external auditory canal and the middle ear has rarely been reported. The authors experienced a very rare case of Jacobson's nerve schwannoma that extended into the external auditory canal in a 55-year-old woman. The tumor eroded the wall of the cochlear promontory and exposed the membranous labyrinth. The jugular foramen and the wall of the ear canal were preserved without destruction. This report represents the first documented case of a Jacobson's nerve schwannoma, which involved the external auditory canal.
