Types of Hearing Loss
Conductive Hearing Loss
If there is a problem in the external or middle ear, a conductive hearing loss exists. This means sound is not being conducted properly to the inner ear. Common causes of conductive hearing loss are ear wax (cerumen) in the external ear, fluid in the middle ear, or a hole or tear (perforation) in the eardrum. Most types of conductive hearing loss can be treated medically or surgically.
Sensorineural Hearing Loss
If a problem occurs in the inner ear, the hearing loss is sensorineural. Sensorineural hearing loss usually cannot be cured medically or surgically, but the use of hearing aids or other amplifying systems can help children hear and develop speech and language.
Mixed Hearing Loss
Children with sensorineural hearing loss also can develop middle ear problems (such as fluid in the middle ear) This can make the infant's hearing loss worse. When there is a combination of two problems (sensorineural and conductive hearing loss), this is known as a mixed hearing loss.
