Abstract
A 59-year-old female developed a sudden perilymphatic fistula due to overexertion when passing stool. Because of severe dizziness and hearing loss, the patient underwent a surgical exploration of the tympanic cavity 4 days after onset. During surgery, the level of the anesthesia became low and the patient started to demonstrate retching which resulted in a clear visualization of the perilymph leak from the round window. Although her dizziness disappeared completely, her hearing recovered but later once again deteriorated. We, thus, believe that a probe tympanotomy is advisable when perilymphatic fistula is suspected in cases of sudden deafness.
