Abstract

One hundred nineteen patients (63 men, 56 women) complaining of severe tinnitus were seen at the Department of Otolaryngology in Nippon Koukan Hospital and Koukan Clinic during the two-year period from April 2004 to March 2006. Of these, 61 (33 men, 28 women) underwent TRT (Tinnitus Retraining Therapy) with the TCI (Tinnitus Control Instrument) and were followed up. We conducted a questionnaire survey of the patients, using the THI (Tinnitus Handicap Inventory). Then, we divided the cases into 2 groups, namely, the Hearing Gap (+) group (19 cases; 10 men and 9 women) and the Hearing Gap (-) group (42 cases; 24 men and 18 women), based on the presence or absence, respectively, of a greater than 10dB difference in the ear of hearing loss between in the right ear and the left ear between the affected ear and the contralateral ear? in the patients.<br>We compared the two groups in terms of the age, score in the? THI (Tinnitus Handicap Inventory), VAS (Visual Analoque Scale) score, and the average hearing level. tinnitus loudness pitch match type of hearing loss type, origin of tinnitus, THI (Tinnitus Handicap Inventory) score, and average of mean hearing level, and the loudness of the tinnitus loudness at the first examination between the two groups The loudness pitch of the tinnitus was related to the type of hearing loss, the origin of the tinnitus, the THI score, the average hearing level and the loudnss pitch of the tnnnitus at the first examination in both the groups??. The results revealed that the THI score, average hearing level and tinnitus loudness were higher in the Hearing Gap (+) group than in the Hearing Gap (-) group.<br>The results revealed that many patients chose speech noise or white noise.<br>We observed that many patients in the Hearing Loss (-) group chose the speech noises of the TCI, which are low-frequency sounds, but whereas many patients in the Hearing Gap (+) group tended to choose the white noise of the TCI, representing which sounds of all frequencies level which is composed of sounds of diverse frequency levels.<br>These results may be of help in guiding physicians to determine the noise type of a the TCI for TRT.
