What is Perilymph Fistula?

Perilymph fistula is a defect in the oval or round window membranes that allows perilymph fluid to leak from the inner ear into the middle ear. Causes include barotrauma, head trauma, Valsalva maneuver, chronic otitis media, and congenital anomalies. It is characterized by fluctuating sensorineural hearing loss, positional vertigo, and pressure-induced symptoms. Diagnosis is challenging and often confirmed by surgical exploration.

Symptoms

Fluctuating hearing loss

Positional dizziness

Vertigo triggered by pressure changes

Aural fullness and tinnitus

Imbalance worsening with exertion

Risk Factors

Barotrauma (diving, air travel)

Head trauma

Excessive straining and heavy lifting

Chronic middle ear disease

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

If sudden hearing loss develops after trauma
If pressure changes provoke dizziness
If hearing levels are fluctuating

Treatment Methods

Bed rest and head elevation

Activity restriction and avoiding straining

Tympanotomy and surgical fistula repair

Window obliteration with autologous graft

Postoperative activity restriction and follow-up
