Insights
Ventilation tube insertion for otitis media with effusion in children significantly improves central auditory processing, including speech discrimination and noise perception, restoring hearing abilities.
Area of Science:
- Pediatric Otolaryngology
- Auditory Neuroscience
- Speech-Language Pathology
Background:
- Otitis media with effusion (OME) is a prevalent childhood condition.
- OME frequently leads to conductive hearing loss and central auditory processing disorders (CAPD).
Purpose of the Study:
- To determine if resolving conductive hearing loss via ventilation tube (VT) insertion improves CAPD in children with OME.
- To assess the impact of VT insertion on various central auditory functions.
Main Methods:
- Cross-sectional study involving 20 children (6-12 years) with OME and 20 controls.
- Central auditory processing evaluated pre- and post-VT insertion using Speech Discrimination Score, Speech Reception Threshold, Words-in-Noise, Speech in Noise, and Consonant Vowel in Noise tests.
Main Results:
- Children with OME showed poorer performance on most auditory tests compared to controls before VT insertion.
- Post-VT insertion, patients demonstrated significant improvements in Speech Discrimination Score and Consonant Vowel in Noise tests.
- Auditory test scores in the patient group approached those of the control group after VT insertion.
Conclusions:
- Ventilation tube treatment effectively restores normal hearing in children with OME.
- Improved hearing following VT insertion leads to enhanced central auditory abilities, including speech reception and discrimination.
- Treatment positively impacts the ability to process speech in noisy environments.
Introduction:
Otitis media with effusion is one of the most common diseases among children. The purpose of this research is to investigate whether the resolvement of conductive hearing loss from the insertion of a ventilation tube also improves central auditory processing disorders in children with otitis media with effusion.
Method:
In this cross-sectional study, 20 children between 6 and 12 years old were diagnosed with otitis media with effusion and 20 normal children were included in the study. The central auditory processing status was evaluated in all patients before ventilation tube insertion and after six months by Speech Discrimination Score, Speech Reception Threshold, Words-in-Noise, Speech in Noise, Consonant Vowel in Noise tests, and the results were compared.
Results:
The mean score of Speech Discrimination Score and Consonant Vowel in Noise tests in the control group were significantly higher than the patient group before ventilation tube insertion and after surgery, in the patient group, the mean scores increased significantly. The mean scores of the Speech Reception Threshold, Words-in-Noise, and Speech in Noise tests in the control group were significantly lower than the patient group before ventilation tube insertion and after the operation, in the patient group, the mean scores significantly decreased. After VT insertion, these tests were close to the control group.
Conclusion:
Restituting normal hearing by ventilation tube treatment improves central auditory abilities as shown in speech reception, speech discrimination, the ability to hear, the ability to recognize monosyllabic words, and the power of speech in the presence of noise.
