Ear Surgeries

4. Perilymphatic fistula surgery

The perilymphatic fistula surgery is performed to restore a good seal of the inner ear windows’ membrane, at the oval window and the round window. Surgical exploration is performed under local anesthesia through the external auditory canal. Once the eardrum is dissected and a small bone edge is removed, the footplate of the stapes is checked to rule out any crack or leak of perilymph. Thereafter, the membrane of the round window is checked.

During each surgical exploration, a systematic blockage of the windows is performed regardless of whether the fistula is or not obvious surgically. Perichondrium or fat is used as materials for clogging.

The advantage of performing this surgery under local anesthesia is the ability to ask the patient to increase intracranial pressure as an attempt to provoke the leak of the perilymph in order to locate the fistula; in addition, is to avoid general anesthesia and have the opportunity to resume normal daily life, the same or the next day after surgery, without missing school or work. Certainly you must follow the doctor’s recommendations.
