For the purpose of clarifying the clinical features of perilymphatic fistula, we investigated the clinical symptoms, tests results and therapeutic results in 24 recent patients with perilymphatic fistula. The inducing factors of perilymphatic fistula, such as blowing the nose, landing in an airplane or diving were found in about half of the patients, while, the other patients had no inducing factors. Hearing loss was the most common symptom, which occurred suddenly in most patients. There was no characteristic tinnitus of the perilymphatic fistula. Pop sound and tinnitus expressed as a stream were observed in only 10% of the patients. Audiogram showed profound deafness in many patients and the configuration of audiogram varied from patient to patient. Positional nystagmus was observed in 33.3% of the patients. Fistula sign was also observed in 50% of the patients. Perilymphatic fistula was commonly found in the round window. Hearing was improved in 5 patients (20.8%) postoperatively. Tinnitus was improved in 7 out of 22 patients (31.8%), and blocked sensation in the ear was improved in 5 out of 14 patients (35.7%). Vertigo or disequilibrium was diminished in 18 out of 21 patients (85.8%). From these results, we contemplated the diagnostic and therapeutic problems in perilymphatic fistula.
