목적: To assess the effectiveness of the 'TINI' laser device for tinnitus symptom relief compared to a Sham device. 방법:The study included 36 chronic high-frequency tinnitus patients with hearing loss, divided into two test groups and a control group. Group 1 received the ‘TINI’ laser for four weeks, Group 2 used the ‘TINI’ device for two weeks followed by a Sham device for another two weeks, and the Control Group used a Sham device for four weeks. Evaluations included the Tinnitus Handicap Inventory (THI), Tinnitus Functional Index (TFI), and Tinnitus Magnitude Index (TMI) at various intervals. 결과:The study administered a 100-mW diode laser at 830-nm or sham laser to 36 participants. While overall THI scores didn't show significant changes, Test Group 1 displayed a notable decrease in the emotional sub- scale of THI after laser treatment. However, no significant changes were observed in the TFI scores for Test Group 1, while Test Group 2 and the Control Group exhibited a significant decrease in TFI scores after laser treatment. TMI scores revealed significant changes in tinnitus loudness and severity in Test Group 1 after laser treatment, indicating the 'TINI' device's effectiveness in reducing perceived tinnitus severity. No adverse effects were reported. 결론:The 'TINI' laser device showed potential in alleviating tinnitus symptoms, particularly in emotional aspects and perceived loudness and severity. The absence of adverse effects underscores its safety. However, further research is needed to optimize the treatment protocol for tinnitus management.
