What is Perilymphatic fistula?

A perilymphatic fistula (PLF) is an abnormal communication between the perilymph-filled inner ear and outside the inner ear that can allow perilymph to leak from the cochlea or vestibule, most commonly through the round or oval window. PLF commonly causes cochlear and vestibular symptoms.

Can perilymph cause hearing loss?

The symptoms of a perilymph fistula most commonly include ear fullness, fluctuating or “sensitive” hearing, dizziness without true vertigo (spinning), and motion intolerance. Vertigo or sudden hearing loss can occur from a PLF.

How is Perilymphatic fistula diagnosed?

CT scans.

How are most cases of perilymphatic fistula treated?

The treatment of perilymphatic fistula is an injection or surgery. While bed rest and nonsurgical treatment have been recommended as treatment of this condition, there is a risk of further deterioration of hearing and balance function.

Can an MRI detect a perilymph fistula?

Conclusion: The combination of CT and MRI is a reliable tool for a fast and accurate diagnosis of round and oval window perilymphatic fistula, with good sensitivity (> 80%).

What are causes of conductive hearing loss?

Common reasons for conductive hearing loss include blockage of your ear canal, a hole in your ear drum, problems with three small bones in your ear, or fluid in the space between your ear drum and cochlea. Fortunately, most cases of conductive hearing loss can be improved.

What causes a perilymph fistula?

The most common cause of a perilymph fistula is head trauma, typically involving a blow to the head. Other causes of perilymph fistula include: Perforated eardrum. Ear trauma.

Can MRI diagnose fistula?

MRI is highly accurate for fistula depiction and, by providing an accurate assessment of disease status and extension, can help surgical planning to minimize recurrence and detect clinically unapparent disease.
