Early ear problems and developmental problems at school age.

Retrospective history of middle ear disease was compared with developmental diagnosis in 507 consecutively referred school-age children. History of major ear problems was positively associated with discrepancies between the performance and verbal IQ on the WISC-R. History of major ear problems was positively associated with the presence of articulation disorders for children in the low social class, hyperactivity in the middle social class, and language problems in the high social class. A history of significant middle ear disease in early childhood should raise concerns for articulation difficulties and possible language problems in children presenting to clinicians with school problems.
