What is ossicular dislocation?
Ossicular dislocation occurs when the bones in the middle ear (ossicles) become separated from each other. This causes loss of hearing.
What causes it?
Ossicular dislocation can be caused by a number of conditions including a temporal bone fracture, traumatic injury to the ear, a hole in the eardrum, chronic otitis media or cholesteatoma.
How can it be treated?
First, your doctor will evaluate your hearing and examine your ear thoroughly. In some cases it may be necessary to confirm the diagnosis with a surgical procedure. If the dislocation is confirmed, an ossicular chain reconstruction can be conducted to restore the continuity of the ossciles and improve hearing.
Depending on the nature of the discontinuity, bone or cartilage from the ear or a prosthesis can be used for the reconstruction.
