Background: Chronic otitis media with effusion (CME) primarily affects
children. Temporary auditory deprivation is a serious complication of this
disease and can result in auditory processing disorder, as demonstrated in past
studies. The objective of the current study was to investigate the effects of CME
duration on binaural processing and amblyaudia.
Methods: Ninety-four children were examined, including 48 children (29
girls=60%) with different CME durations (from 3 months to more than 9
months) and 46 children (34 girls=73%) with no history of CME or a duration
of less than 3 months CME. Persian versions of the dichotic digits and dichotic
rhyme tests were applied.
Results: Significant differences between the groups (P<0.001) in dichotic
digits difference (DDD) and dichotic rhyme difference (DRD) in free recall
conditions were identified. With longer durations of CME, the DDD and DRD
average scores were increased in the CME positive group, and the probability of
amblyaudia was also enhanced.
Conclusion: A history of CME and the long-term auditory deprivation resulting
from it in early childhood can increase the risk of amblyaudia.
