The study investigates the effectiveness of transmeatal low-power laser stimulation (TLLS) for treating persistent tinnitus through a double-blinded, randomized, placebo-controlled trial with patients from outpatient clinics.
Participants were divided into two groups: one received the actual TLLS treatment along with betahistine, while the other group used a placebo device and also took the same medication for 10 weeks.
Although both groups showed improvement in tinnitus symptoms, comparing the TLLS+ group with the TLLS- group revealed no statistically significant difference in treatment outcomes.
