Perilymph fistula

Perilymph fistula (PLF) is a medical condition where there is an abnormal communication, or fistula, that allows the perilymph fluid to leak from the inner ear into the middle ear. This condition can cause a variety of symptoms, including vertigo, tinnitus, and hearing loss.

Causes[edit | edit source]

Perilymph fistulas can be caused by a variety of factors. They can occur as a result of trauma to the ear, such as a blow to the head, rapid changes in atmospheric pressure (such as during scuba diving or air travel), or after ear surgery. They can also occur spontaneously, without any apparent cause.

Symptoms[edit | edit source]

The symptoms of a perilymph fistula can vary widely, but often include vertigo, tinnitus, and hearing loss. Other symptoms can include nausea, vomiting, and a feeling of fullness or pressure in the ear. The symptoms can be intermittent or constant, and can vary in severity.

Diagnosis[edit | edit source]

Diagnosing a perilymph fistula can be challenging, as the symptoms can be similar to those of other conditions. The diagnosis is often made based on the patient's history and symptoms, as well as the results of certain tests, such as a hearing test or balance test. In some cases, the diagnosis can be confirmed by observing the flow of perilymph fluid during surgery.

Treatment[edit | edit source]

The treatment for a perilymph fistula often involves surgery to repair the fistula. This is typically done by placing a graft over the fistula to stop the flow of perilymph fluid. In some cases, medication may be used to help manage the symptoms of the condition.
