Synopsis

A labyrinthine, or perilymph, fistula is an abnormal communication between the inner and middle ear. This communication causes perilymphatic fluid to leak from the inner to middle ear. Patients present with acute vertigo and sensorineural hearing loss. Infection, prior ear surgery, and trauma are common causes of fistula formation. Meningitis, in particular, predisposes patients to a labyrinthine fistula. A labyrinthine fistula can occur in adults or children. Labyrinthine fistulae are surgically repaired, although rarely they may spontaneously heal. Patients should be instructed to remain on bed rest with an elevated head of the bed. This is considered an otologic emergency.
