perilymph fistula

Ucient12 Apr, 2022Health

The inner ear (hearing and balance organs) is encased in bone and communicates with the middle ear (the space behind the ear drum) in two locations. These two areas are covered with a thin membrane and are termed the round and oval windows. If for some reason a communication develops between the inner ear fluid and the middle ear space, it is called a perilymphatic fistula. See Anatomy of the Ear for reference.
