Hearing Thresholds in Young Children With Otitis Media With Effusion With and Without Cleft Palate.

Objective: To investigate hearing thresholds in children born with cleft palate and in children with otitis media with effusion but no cleft palate. Design: Prospective longitudinal group comparison study. Setting: University hospital. Participants: Sixteen children born with nonsyndromic cleft palate with or without cleft lip (CP±L) and 15 age-matched children with otitis media with effusion (OME) but without cleft. Main Outcome Measures: Hearing was tested at repeated occasions beginning with neonatal auditory brainstem response (ABR) at 1-4 months of age, and age-appropriate hearing tests from 9 to 36 months of age. Results: The median ABR thresholds in both groups were elevated but did not differ significantly. At 12 months of age, the median 4 frequency averages at 500-1000-2000-4000 Hz (4FA) were indicative of mild hearing loss but significantly better in the CP±L-group than in the group without cleft (P <.01). There were no significant group-wise differences regarding the median 4FA at 24 and 36 months of age, and at 36 months, the median 4FA were normal in both groups. Both groups exhibited a significant improvement over time from the neonatal ABR thresholds to the 4FA at 36 months (CP±L-group P <.05; without CP±L-group P <.01). Conclusion: The hearing loss in children with CP±L was not more severe than among children with OME but without cleft palate; rather, at 12 months of age, the thresholds were significantly better in the CP±L-group than those in the group without cleft. The air conduction thresholds improved with age in both groups. [ABSTRACT FROM AUTHOR]
