Objective: To analyze the central auditory nervous system function in children suffering from otitis media in the first five years of age. Specific objectives: to parallel, considering gender and age, the results obtained in tests of auditory processing in children without otitis media history and children who suffered from otitis media in childhood; to analyze the amplitude/latency of P300 and ARB tests and to compare the auditory processing and electrophysiological results after an Auditory Training Program. Methods: A total of 90 students between 8 and 14 years old, males and females, were divided into two groups. The Control Group (CG) consisted of 40 students from Public School without otitis media history, the Experimental Group I (EGI) consisted of 50 students from Public School suffering from secretory otitis media in their first five years of age and undergoing a surgery for bilateral ventilation tubes placement. All children underwent complete audiological evaluation and assessment of auditory processing which included the following tests: dichotic digits, synthetic sentence identification with ipsilateral competing message, dichotic consonant vowel test, pitch pattern sequence, gaps-in-noise and electrophysiological tests which included ABR and P300. The subjects presenting a change in the behavioral assessment tests will be included in the auditory training program and subsequently revalued. Expected Results: to find abnormal results in auditory processing test and P300 in children from EGI and normal results in children from CG. After the auditory training program, normal responses are expected in behavioral tests and electrophysiological test.
