Audiological and behavior findings in children underwent a bilateral myringoplasty - a comparative study

ABSTRACT Purpose: to analyze pre-surgical hearing evaluation in children who suffering from secretory otitis media in their first five years of age. Also to verify the length of time tubes have remained in the eardrum and analyze the test results of auditory processing after myringotomy surgery. Method: 79 students between eight and 12 years old were divided into two groups: 1 - 40 students without otitis media history and 2 - 39 students suffering from secretory otitis media in their first five years of age and who have undergone a myringotomy surgery. The individuals underwent complete audiological evaluation and assessment of Auditory Processing. Results: all patients showed conductive hearing loss in the pre-operative audiologic tests. The mean time of ventilation tubes was 11,8 months. The left ear showed significant lower performance in the dichotic digits and pitch pattern sequence tests. The students from group 2 showed lower performance whether compared to group 1 in the dichotic digits test and gaps-in-noise. Conclusion: children with a history of otitis media in the early years of life showed the conductive hearing loss responses in the pre-surgical evaluation and lower responses in dichotic test of digits and gaps-in-noise.
