Can Traditional Chinese Medicine Treat Sensorineural Hearing Loss?

Neurosensorial hearing loss—often referred to as sensorineural hearing loss (SNHL)—arises from damage to the inner ear’s hair cells, the auditory nerve, or central auditory pathways. Unlike conductive hearing loss, which involves mechanical obstruction or dysfunction in the outer or middle ear, SNHL is typically irreversible and does not respond to surgical or medical interventions aimed at restoring structural integrity.

While some cases of sudden sensorineural hearing loss (SSNHL) may benefit from prompt corticosteroid therapy—especially when initiated within 72 hours of onset—there is no robust clinical evidence supporting the efficacy of traditional Chinese herbal medicine (TCM) for treating established or chronic SNHL. Major international guidelines, including those from the American Academy of Otolaryngology–Head and Neck Surgery (AAO-HNS) and the European Consensus Statement on SSNHL, emphasize evidence-based approaches such as systemic or intratympanic corticosteroids, with careful audiological monitoring and, where appropriate, hearing rehabilitation via amplification or cochlear implantation.

Although certain TCM formulations have been explored in small, low-powered studies—often with methodological limitations including lack of blinding, inadequate control groups, or inconsistent outcome measures—none have demonstrated reproducible, statistically significant improvements in pure-tone audiometry thresholds or speech discrimination scores in rigorously designed randomized controlled trials. Moreover, herbal preparations carry potential risks, including hepatotoxicity, nephrotoxicity, and herb–drug interactions, particularly in patients receiving concurrent medications such as anticoagulants or immunosuppressants.

Clinicians advise against delaying evidence-based care in favor of unproven herbal therapies, especially in acute presentations where timely intervention can influence outcomes. Patients experiencing sudden or progressive hearing loss should seek immediate evaluation by an otolaryngologist or audiologist for comprehensive diagnostic workup—including audiometry, tympanometry, and, if indicated, MRI—to rule out retrocochlear pathology such as vestibular schwannoma.

In summary, while integrative approaches may hold interest for supportive symptom management, current scientific consensus affirms that no herbal remedy has met the evidentiary threshold required to be recommended as a treatment for sensorineural hearing loss.
