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]

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]

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

These factors lend credence to the theory that patients with GJB2 and GJB6 mutations may have a favorable prognosis following cochlear implantation, and that patients with other mutations or without a documented mutation may have a less favorable prognosis [bcidaho.com]
