Sound energy is blocked from reaching the inner ear normally.
Possible causes include: fluid behind eardrum, earwax build-up, perforated eardrum, fixation of middle ear bones, etc.
In many cases, it may be medically or surgically treatable.
Typically, these individuals obtain significant benefit from hearing aids; however, surgical correction is frequently an option if medically appropriate.
May receive significant benefit from osseointergrated implanted hearing aids if medical treatment or air conduction hearing aids are not appropriate.
Sensorineural Hearing Loss
Inner ear (cochlea) and/or hearing nerve damaged so sound is not processed normally.
Possible causes include: noise, medications, disease, aging etc. In some cases (less than 10%), it is medically or surgically treatable.
These individuals often obtain significant benefit from hearing aids or other amplifying devices.
Cochlear implants often provide significant hearing to children and adults who do not receive benefit from hearing aids.
Mixed Hearing Loss
There is both a conductive and a sensorineural part to the hearing loss.
A portion of the loss may be medically or surgically treatable.
Typically, these individuals will obtain significant benefit from hearing aids or other amplifying devices.
