This is a case report of an 18‐year‐old Negro female who presented with the chief complaint of a long standing hearing loss. Physical examination revealed a large mass in the right external auditory canal which occupied 80 percent of the cross section area. There was only a tiny rim of the inferior tympanic membrane visable. The patient had a 60 db conductive hearing loss. Mastoid films were normal. At surgery the mass was found to extend into the attic and to almost completely fill the middle ear. When the tumor was removed from the attic, under the malleus and the hypotympanic area, the only attachment was the chorda tympani nerve. The pathology report was neuroma. Photographs were taken and illustrations are presented to confirm these findings. Neuroma has been reported as originating from every branch of the facial nerve with the exception of the chorda tympani nerve. This site of origin has been strikingly absent, especially since the chorda tympani is a component of the facial nerve. Our case is presented to document such an occurrence.
