- To detect cholesteatoma (tumor or abnormal skin growth in the middle ear behind the eardrum)
- To find out meningoencephalocele or meningocele (congenital or birth defect condition where spinal cord of the baby fails to develop)
- To evaluate inner ear swelling which connects ear to the brain resulting in vertigo
