INCREASINGLY, otologic surgeons are becoming aware that poststapes surgery perilymph fistulas are among the most serious and yet the most common (except for infection) complications. This entity, often impossible to differentiate clinically from endolymphatic hydrops, is now considered to be one of the main factors in previously unexplained early and late sensorineural hearing losses. This case report, with histopathologic confirmation of epithelial lined multiple perilymphatic fistulae and an associated asymmetrically positioned prosthesis, forms the basis for further discussion on this unsolved problem.
Report of a Case
A 74-year-old white man had noticed a gradual and progressive loss of hearing for about five years. He had bought a hearing aid two years before but had used it for only nine months with minimal subjective satisfaction. There was no history of fluctuations in his hearing, otitis media, tinnitus, or vertigo. His mother had a similar hearing loss. Hypocycloidal polytomography (by Dr. Valvassori)
