A labyrinthine fistula is an abnormal opening in the inner ear. This can result in leakage of the perilymph into the middle ear.[1] This includes specifically a perilymph fistula (PLF), an abnormal connection between the fluid of the inner ear and the air-filled middle ear. This is caused by a rupture of the round window or oval window ligaments separating the inner and middle ear.[1]

Treatment
Patients are advised to treat with bed rest and avoiding activities that increase intracranial pressure (i.e. weightlifting, Valsalva maneuver, scuba diving, flying in airplanes) with the hopes of the membrane healing on its own. Appropriate Physical therapy / vestibular rehabilitation techniques can be helpful in managing symptoms of movement sensitivity.[1]
