Abstract

Objective

To describe and compare the latencies and amplitudes of Mismatch Negativity between children with and without Developmental Dyslexia.

Methods

Cross-sectional and comparative study, consisting of a study group of 52 children with Developmental Dyslexia and a control group of 52 children with typical development, matched by age and sex, aged between 9 years and 11 years and 11 months of both sexes. All participants underwent Otoscopy, Acoustic Immittance Measurements, Pure Tone Audiometry, Speech Audiometry, Brainstem Auditory Evoked Potential and Mismatch Negativity.

Results

It was verified a statistically significant difference when comparing Mismatch Negativity latencies between the groups, with higher values for children with Developmental Dyslexia (p = 0.012). However, there was no statistically significant difference in Mismatch Negativity amplitudes between the groups studied.

Conclusion

The results suggest that children with Developmental Dyslexia may present difficulties in auditory processing and discrimination skills compared to children with typical development.

发展性阅读障碍儿童的错配负性。

目的：描述和比较发展性阅读障碍儿童和非发展性阅读障碍儿童错配负性的潜伏期和振幅。方法：采用横断面对比研究方法，将发育性阅读障碍患儿52例作为研究组，将发育典型患儿52例作为对照组，按年龄和性别匹配，年龄在9岁至11岁11个月之间。所有的参与者都接受了耳镜检查、声阻抗测量、纯音测听、语音测听、脑干听觉诱发电位和失配负性测试。结果：错配负性潜伏期组间比较差异有统计学意义，发展性阅读障碍组的错配负性潜伏期较高（p = 0.012）。然而，错配负性振幅在两组间无统计学差异。结论：发展性阅读障碍儿童在听觉处理和辨别技能方面可能比正常发育儿童存在困难。

期刊介绍： The purpose of the International Journal of Pediatric Otorhinolaryngology is to concentrate and disseminate information concerning prevention, cure and care of otorhinolaryngological disorders in infants and children due to developmental, degenerative, infectious, neoplastic, traumatic, social, psychiatric and economic causes. The Journal provides a medium for clinical and basic contributions in all of the areas of pediatric otorhinolaryngology. This includes medical and surgical otology, bronchoesophagology, laryngology, rhinology, diseases of the head and neck, and disorders of communication, including voice, speech and language disorders.
