Abstract

|
|
Tinnitus is noise from ear or head without any external sound stimulation and can cause hearing difficulties, psychogenic disturbances or many difficulties in everyday life. The etiology has yet been discussed and the management is also very difficult. Our study was performed to evaluate the clinical characteristics of idiopathic tinnitus.
Three hundred thirty five patients(417 ears) with idiopathic tinnitus were entered into our department´s database between Nov. 1995 and Oct. 1997. The patients were fully questioned about their history, and then were physically examined and assessed audiometrically, including pure tone audiogram and tinnitogram.
It was found that (1) there was no sexual difference, (2) average age was 48.5 years, (3) there was no laterality, (4) buzzing sound was the most common, (5) average symptom duration was 575.7 days, (6) the most common sensation level was within 5dB, (7) the most common loudness was less than 29dB, and (8) the most common frequency was over 8000Hz.
