Treatment Treatment for nonsyndromic deafness includes utilization of hearing aids as well as vibrotactile devices. For children over the age of 12 months with severe to profound hearing loss, cochlear implantation might be considered an option. [mazornet.com]

This type of hearing loss may be responsive to medical or surgical treatment. Mixed hearing loss is the result of damage to conductive pathways of the outer and/or middle ear and to the nerves or sensory hair cells of the inner ear. [asha.org]

Possible treatments include hearing aids, cochlear implants, special training, certain medicines, and surgery. [icdlist.com]
