A perilymph fistula is an abnormal communication that allows perilymph fluid to leak from the inner ear into the middle ear. This condition occurs when there is a tear or small defect in the membranes that separates the air-filled middle ear from the fluid-filled inner ear.
The leakage of perilymph fluid can lead to a range of symptoms, including vertigo, hearing issues, ringing in the ears, and balance problems. Patients may experience sudden episodes of dizziness or a spinning sensation, along with fluctuating hearing loss, which can significantly impact their quality of life.
