Abstract

Perilymphatic fistula (PLF) is a rare condition characterized by abnormal leakage of perilymph from the inner ear into the middle ear via a defect in the oval or round windows. PLF needs special attention concerning early diagnosis and treatment, because it can cause dizziness, hearing loss, tinnitus, meningitis, and other symptoms. The diagnosis of PLF usually cannot be confirmed before exploratory tympanotomy. Fascia, perichondrium, loose areolar tissue, fat and gelfoam can be used effectively in the PLF repair. Fibrin glue was used to aid in securing the graft material. However, recurrence is not rare and revision is sometimes needed to relieve the symptoms associated with the leakage of perilymph. So otologic surgeons should keep in mind that PLF has a great tendency to recur. Careful surgical procedures together with strict postoperative management are important to prevent recurrence and hydroxyapatite cement (HAC) can be used to cover the fistula area as a alternative graft material in recurrent perilymphatic fistula. We report on one recurrent case of postoperative PLF occurring at the round window that was repaired with HAC.
