Conductive hearing loss
Any problem in the outer or middle ear that results in the sound not conducted appropriately is called conductive hearing loss. The conductive hearing loss is usually mild or moderate, between 25 and 65 decibels.
Sensorineural hearing loss
Sensorineural hearing loss is due to the absence or destruction of sensors cells (hair cells) of the cochlea and is usually permanent. Known as hearing perception loss, the sensorineural hearing loss can be mild, moderate, severe or profound.
Mild to severe sensorineural hearing loss can be treated with hearing aids or a middle ear implant. Cochlear implants are often the solution for severe or profound hearing loss.
Mixed hearing loss
Mixed hearing loss combines sensorineural hearing loss and conductive hearing loss. Due to problems in both the inner and the outer or the middle ear. Treatment options include medication, surgery, hearing aids, middle ear implants or bone conduction implants.
Neural hearing loss
A problem due to lack or damage of the auditory nerve can cause a neural hearing loss. Neural hearing loss is usually severe and permanent.
