Analysis
Various forms of hearing impairment exist. Conductive deafness, for example, affects the eardrum and the ossicles.  This is a mechanical disturbance of the transmission of sound waves from the eardrum to the inner ear. Labyrinthine deafness, on the other hand, is a disturbance of the sensory cells in the organ of Corti.  They are no longer able to convert the vibrations in the inner ear fluids into nerve impulses.

Conservative treatments
Depending on the type and severity of hearing impairment, medication or hearing aids can  help. Both tests of hearing and microscopic examination of the ear are needed in order to establish which treatment possibilities are recommended. In specific cases, CAT scans or MRI imaging may be called for. 

Microsurgical intervention
Most ossicle or eardrum defects can be surgically repaired.  To this end, a patient’s own tissue is used, though if none is available, artificial substitutes may be used.
