Abstract

|
|
The traumatic perilymphatic fistula (PLF) can cause hearing loss and disabling dizziness.
These symptoms can be recovered spontaneously or by surgical repair. However, even aftersurgical PLF repair, patients may suffer from recurrent vestibular symptoms. The mechanismof recurrent symptoms is not clear. We experienced two patients who complained of recurrentvertigo long after surgical PLF repair. Both patients had severe sensorineural hearing loss andvestibular loss after head trauma. In both cases, after surgical repair, dizziness was completelysubsided. However, several years later, the disabling vertigo recurred in both cases. The symptomsaggravated when position was changed. On the fistula test, the patients showed positiveresults. Surgical findings showed a fibrous band connection between the stapes and the tympanicmembrane. After stapedectomy, the symptoms subsided. We discuss the two cases inregards to the possible mechanism of recurrent vertigo after surgical PLF repair
