TYPES OF HEARING LOSS

A conductive hearing loss occurs when there is problem in the outer or middle ear. Essentially, there is problem conducting sound efficiently through the outer ear and middle ear structures. It occurs because the sound entering the ear is reduced or dampened. However, unlike a sensorineural loss, it can be partially or totally reversed with medical intervention

What causes a Conductive hearing loss?

Malformation of the outer or middle ear structures, abnormal bone growth in the middle ear, a hole in the eardrum, a middle ear infection in which fluid accumulates behind the eardrum, or poor Eustachian tube dysfunction may cause conductive hearing loss. Treatment for conductive hearing loss varies based on the circumstances. Hearing aids are often the best answer when surgery is not possible, because they significantly improve hearing and are convenient.

What is sensorineural hearing loss?

Sensorineural hearing loss refers to any reduction in hearing sensitivity or sound clarity that is caused by damage to the structures of the inner ear or the nerve pathways. Sensorineural hearing loss usually occurs slowly. Exposure to very loud noise is the most common cause of sensorineural hearing loss followed by aging known as Presbycusis. Certain medications such as quinine and health conditions are also known causes of sensorineural hearing loss.Hearing aids are the primary treatment for sensorineural hearing loss as surgical intervention is rarely possible. Cochlear implantation may be recommended, depending on candidacy.

What is a mixed hearing loss?

A mixed hearing loss is a combination of a conductive and sensorineural hearing loss and affects both the outer or middle ear and the inner ear.   Therefore there is likely to be damage in the outer or middle ear structures and the inner ear or auditory nerve. Causes for a mixed hearing loss vary and treatment may include medications or surgery for the conductive component and amplification (hearing aids) for the sensorineural component.
