Treatment or surgery can often reverse this kind of hearing loss. Untreated, hearing problems can get worse. If you have trouble hearing, you can get help. [icdlist.com]

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]
Prognosis
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]
Acquired causes should be differentiated from genetic causes to inform the evaluation and required ancillary testing (i.e., CT, MRI, and consultation with specialists) and to inform prognosis and treatment recommendations. Figure 2. [ncbi.nlm.nih.gov]
Etiology
Deafness is influenced by both genetic and environmental factors, with inherited causes as the most prominent etiological factor in deafness in developed countries. [degruyter.com]
