Abstract:
Background and Objectives:Tinnitus, although being a common chronic disease, can be an intractable disease that causes depression and insomnia. This study aimed to analyze the results of the Tinnitus Handicap Inventory (THI), Beck Depression Inventory (BDI), and Pittsburgh Sleep Quality Index (PSQI) questionnaire surveys before and after clonazepam therapy. In addition, we analyzed the association of three pre-treatment questionnaires and evaluated whether pre-treatment factors could predict the post-treatment THI index.Subjects and Method Patients were selected from those who visited a tertiary hospital from 2019 to 2021 for the treatment of chronic tinnitus they had for more than 3 months and who were over 20 years old. Patients were excluded from the study if they were diagnosed with acute sudden hearing loss, Meniere’s disease, brain/internal auditory canal tumors, or muscular/vascular tinnitus. The questionnaire surveys of THI, BDI, PSQI were conducted before and after 3 months of clonazepam therapy (Rivotril [Roche Inc.] 0.25 or 0.5 mg). Questionnaire scores were compared using the paired t-test. Multiple regression analysis was used to determine the relationships among the three questionnaires.
Results:A total of 76 patients (38 males and 38 females) with the mean age of 57.2±9.01 years was analyzed. The average hearing threshold was 30.4±20.67 dB HL on the right and 31.7±17.06 dB HL on the left. The pre-treatment THI, BDI, and PSQI scores were 44.3±23.4, 7.96±2.36, and 6.85±4.68, respectively. The relationships between the THI and BDI and the THI and PSQI were significant (p=0.0027 and p<0.0001, respectively). The pre-THI score showed no significant association with age, sex, or hearing threshold (p=0.91, 0.85, and 0.23, respectively). The post-treatment THI score was 33.6±17.1, which was significantly lower than the pre-THI scores (p<0.0001). Post-BDI and post-PSQI were 7.38±2.25 and 4.04±3.20, respectively. Post-PSQI also significantly decreased compared with pre-PSQI (p=0.0002), but post-BDI did not significantly decrease (p=0.1231). In the THI survey, Question 7 (sleep disturbance) showed decrease the most, followed by Question 25 (unstable mood). The post-treatment THI could be predicted by using the formula, 0.7673+0.6947×pre-THI+0.3572×pre-PSQI.
Conclusion:The appropriate/optional use of clonazepam at low doses (0.25-0.5 mg) can significantly improve chronic tinnitus and sleep quality. Tinnitus was significantly associated with the scores of THI, BDI, PSQI and the usage of Clonazepam significantly reduced the THI and PSQI scores. However, clonazepam did not affect the BDI score.
