Evaluating Your Child for Ossicular Chain DislocationTo determine if your child has ossicular chain dislocation, the Children’s Hearing Center team will:
- Evaluate your child’s hearing
- Examine your child’s ear with a microscope
- Request a computed tomography (CT) scan, if needed, to determine the extent of the disease. The CT scan can also provide images to guide surgery.
Ossicular Chain Dislocation Surgery OutcomesThe success rate of ossicular chain dislocation repair depends on the stapes.
- If the stapes is intact, the rate of good hearing recovery is about 75 percent.
- If the stapes is not intact, the rate of good hearing recovery is about 50 percent.
