Sudden Hearing Loss

​

Sudden hearing loss is a hearing impairment originating from the inner ear that usually occurs within the last three days, often accompanied by ringing or buzzing. It is an urgent condition that requires immediate intervention.

Structures related to the inner ear, such as the cochlea, semicircular canals, and the auditory nerve, are involved in sudden hearing loss. It can range from mild to complete deafness and is typically unilateral. If the hearing loss is significant, recovery can be challenging.

The exact cause is not fully understood, but it can be attributed to viral infections, vascular events, immune system disorders, medications, and the rupture of the inner ear membrane. Viral infections such as mumps, measles, and upper respiratory tract infections can lead to sudden hearing loss by affecting the inner ear. Inner ear tumors can also present with sudden hearing loss. Increased fluid pressure in the inner ear can cause membrane rupture and deafness. Other factors that increase fluid pressure include head or ear trauma, changes in pressure, and exposure to loud noises.

Vascular theory suggests that the constriction or blockage of blood vessels that supply the inner ear plays a significant role. Patients may notice the onset of hearing loss suddenly or within a few hours or days.

It is crucial to consult an ENT specialist promptly for a comprehensive hearing assessment. The earlier the treatment for sudden hearing loss begins, the higher the chances of success. In addition to medication administered through veins or the mouth, intratympanic injections performed in our clinic and hyperbaric oxygen therapy can be beneficial.

Age-Related Hearing Loss (Presbycusis)

​

Presbycusis is the gradual hearing loss that occurs with aging, affecting the auditory system as a natural consequence of getting older. As the senses weaken over time, presbycusis manifests in the inner ear, affecting the cells and nerves responsible for hearing, as well as the brain cells. This age-related hearing loss typically begins around the age of 65 and is prevalent in almost all individuals aged 80 and older. It is often significantly mitigated through hearing aids. Before discussing the symptoms of age-related hearing loss, it is important to understand what presbycusis is.
