Interventional Treatment of Chronic Tinnitus With Acoustic Stimulation

The《Clinical practice guideline: tinnitus》defines tinnitus as the perception of sound without an external source, with patients lasting six months or longer classified as chronic tinnitus. Epidemiological studies indicate that tinnitus affects up to 25% of the global population. With a worldwide estimated 7.2 billion people affected, which translates to approximately 1.8 billion individuals impacted. Among these, 33% (about 590 million people) experience varying degrees of hearing impairment, and severely disrupting their work, daily life, and social interactions. Furthermore, 10%-15% of patients (approximately 180～270 million) require medical treatment or intervention. Notably, tinnitus prevalence increases with age: it affects about 29.7% of those over 60 and rises to 33% for those aged 65 and above. These statistics demonstrate that tinnitus has become one of the most significant global health challenges. In recent years, many studies have proposed an innovative therapeutic approach for tinnitus based on new research advancements in its pathogenesis. The methods termed Active Tinnitus Stimulation Therapy (ATST) and focuses on central mechanisms of tinnitus, abnormal neuronal discharges, and neural plasticity in related brain regions. The therapy tailors acoustic stimulation protocols according to individual hearing loss severity and tinnitus characteristics. Specifically, tailored acoustic signals are converted into electrical impulses in the cochlea, transmitted through …
