OBJECTIVES: To analyze the central auditory nervous system function through behavioral and electrophysiological tests in children with a history of otitis media and subsequent bilateral tubes placement surgery.
METHODS: The participants were divided into two groups between eight and 14 years old: control group (CG) consisted of 40 children with no history of otitis media; experimental group (EG) consisted of 50 children with documented history of otitis media and undertook a surgery for bilateral tubes placement. All children completed audiological evaluation (audiometry, speech audiometry, and immittance audiometry), behavioral evaluation (tests: dichotic digits, synthetic sentence identification with ipsilateral competing message, gaps-in-noise, frequency pattern), and electrophysiological evaluation (Auditory Brainstem Response, ABR, Frequency Following Response, FFR (verbal), and Long Latency Auditory Evoked Potential, LLAEP).
RESULTS: The EG group showed significantly poorer performance (p<0.001) than the CG for all auditory abilities studied. The results revealed significant latency delays and reduced amplitude (p<0.05) of waves III and V for ABR; significant latency delay was seen of potentials P2, N2, and P300 for LLAEP; significant latency delays and reduced amplitude (p<0.05) were observed for FFR in children with a history of otitis media.
CONCLUSION: The results demonstrate negative effect of otitis media in the auditory abilities and electrophysiological measures in children with a history of otitis media.
