From a western clinical perspective, tinnitus commonly develops after peripheral injury (e.g., noise-induced or age-related hearing loss) that reduces auditory input. The central auditory system compensates with increased spontaneous firing, neural synchrony, and reorganization in the dorsal cochlear nucleus, inferior colliculus, thalamus, and auditory cortex. Limbic and attentional networks—particularly those governing salience, arousal, and emotional regulation—shape how intrusive the symptom feels. Stress, sleep disturbance, and anxiety heighten this salience and often drive care seeking. Acupuncture is explored as a supportive modality because it can influence central nervous system function, autonomic tone, and affective distress in related conditions. Hypothesized mechanisms for tinnitus include modulation of cortical excitability and synchronization, improvement in regional blood flow, and dampening of sympathetic arousal that exacerbates tinnitus perception. Electroacupuncture may augment neuromodulation through patterned stimulation. Clinical evidence, however, is mixed. Systematic reviews of randomized trials report small-to-moderate improvements in patient-reported measures such as the Tinnitus Handicap Inventory and loudness or annoyance ratings in some studies, but effects compared with sham acupuncture are inconsistent. Methodological issues—small samples, heterogeneity in points and dosing, and the difficulty of creating physiologically inert shams—limit certainty. As a result, ENT guidelines prioritize cognitive behavioral therapy for distress, hearing aids and sound therapy when hearing loss is present, and patient education. Acupuncture can be considered as an adjunct when patients are interested, particularly when stress, insomnia, or anxiety are prominent. Safety data are reassuring under trained practitioners, though electroacupuncture is used cautiously in those with implanted electrical devices. Who is most likely to respond? Patients with chronic subjective, nonpulsatile tinnitus, especially with comorbid anxiety or sleep issues, may perceive benefit through reduced distress and improved coping. Those with pulsatile tinnitus or red-flag symptoms require medical evaluation for vascular, muscular, or neurologic causes. Expectations should be realistic: complete resolution is uncommon; when benefit occurs, it often manifests as modest reductions in handicap or annoyance over weeks rather than days, and durability beyond several months is uncertain.
