Abstract

Of the 150 patients admitted in 2001 to the Tinnitus Center located at the Nofer Institute of Occupational Medicine, Łódź, Poland, 80 were subjected to complex examinations consisted of standardized questionnaire on medical history, psychological tests and audiological assessment.
The diagnostic procedure was completed for 52 patients (23 females and 29 males; mean age: 53 years). In this group, five patients were found to have conductive hearing loss due to chronic eustachtis or otosclerosis. They were excluded from further studies. Among the other 47 patients, 26 showed normal hearing threshold and 21 suffered from uni- or bilateral sensorineural hearing loss. Hyperacusis was diagnosed in 16 cases. The measurements of brainstem evoked potentials revealed V wave latency asymmetry in 7 cases, which implied the necessity to perform CT or MNR. In neither of cases did this diagnosis confirm the suspected tumor development (n. VIII neurinoma) or pontocerebral angle tumor.
The preliminary assessment of treatment efficacy for subjective tinnitus with use of retraing therapy yielded the following conclusions:
1. The application of hearing aid brings about an immediate improvement in the patientśs self-assessment of hearing and a better tolerance towards tinnitus.
2. A systematic all-day wear of noise generators contributes to the patientśs increased tolerance towards tinnitus, improved mental condition and alleviated hyperacusis.
3. The efficacy of the tinnitus retraining therapy,following Jastreboff, depends on providing the patient with detailed information on the causes and mechanisms of tinnitus development.
4. The negative diagnostics for tumor within the cranial cavity has not only a soothing effect on the patient as it relieves his/her stress, but it can also be a good starting point for the tinnitus retraining therapy.
