Neurogenic tinnitus and deafness is a subtype of tinnitus. So, what exactly is neurogenic tinnitus and deafness?

What Is Neurogenic Tinnitus and Deafness?

Neurogenic tinnitus and deafness typically result from pathological changes affecting the auditory nerve or the central auditory cortex in the brain, leading to hearing loss or tinnitus. It may arise from acute or chronic conditions, and may affect either one ear (unilateral) or both ears (bilateral). A common presentation is sudden sensorineural hearing loss or tinnitus occurring unilaterally. Similarly, age-related hearing loss and tinnitus—commonly seen in elderly patients—are also classified as neurogenic tinnitus and deafness. Additionally, noise-induced hearing loss—frequently observed among individuals with prolonged occupational exposure to loud noise—is likewise considered a form of neurogenic tinnitus and deafness. Furthermore, certain congenital or hereditary hearing disorders—such as enlarged vestibular aqueduct syndrome—are also categorized under neurogenic tinnitus and deafness.

Since sound signals are transmitted via the auditory nerve, any damage—including numbness or necrosis—to this nerve inevitably leads to hearing impairment or deafness. The severity of auditory nerve injury determines clinical manifestations: mild damage may cause tinnitus alone, whereas more severe injury results in frank deafness. Fundamentally, tinnitus originates from auditory nerve damage; therefore, effective treatment of tinnitus and deafness requires neural repair, regeneration, and functional reactivation of the auditory nerve.

Patients with neurogenic tinnitus and deafness should pay attention to dietary habits, which can help effectively prevent the onset or progression of tinnitus. An optimal diet follows the “two-highs, two-lows” principle: high in protein and vitamins, and low in fat and salt. Recommended foods include soups made from lean meats and fresh fish, as well as fruits and vegetables rich in vitamins—such as leeks, carrots, and celery. We hope this article has been helpful.
