title: Mastoid abnormalities in Down syndrome.
abstract: Hearing loss and otitis media are commonly associated with Down syndrome. Hypoplasia of the mastoids is seen in many affected children and sclerosis of mastoid bones is not uncommon in Down syndrome. Awareness and early recognition of mastoid abnormality may lead to appropriate and timely therapy, thereby preserving the child's hearing or compensating for hearing loss; factors which are important for learning and maximum development.
