Otitis media, auditory sensitivity, and language outcomes at one year.

Abstract

The relationship among otitis media, auditory sensitivity, and emerging language was examined in a group of 1-year-old children who were prospectively followed since birth. Pneumatic otoscopy was used to document the otologic status of the children's ears at each medical visit. There were 13 babies with normal ratings in each ear at 80% more of their visits (designated as "otitis free") and 12 babies with bilaterally positive otoscopy results at 30% or more of their first year visits (designated "otitis positive"). In comparison to the otitis free infants, the group of otitis positive babies demonstrated reduced auditory sensitivity as measured by auditory brain stem response (ABR) and poorer expressive language abilities. However, differences in receptive language were not detected. These results suggest that otitis media may have an impact on auditory sensitivity and developing language as early as 1 year of age.
