Fatores na infância e adolescência que podem influenciar o processamento auditivo: revisão sistemática

Auditory assessment and central auditory processing script for preschool children

PURPOSE

To develop an assessment script to observe hearing and central auditory processing in preschool children.

METHODS

To The script was prepared based on a search in the Scielo databases and in the library of a university in the state of São Paulo using the following keywords: "central auditory processing", "hearing and language", "auditory processing disorders", "auditory processing in preschool children", and "vocabulary assessment", resulting in the selection of fourteen articles and two books. Then, questions related to auditory development and a script for assessing central auditory processing were prepared.

RESULTS

The script consists of eight parts, namely: Identification and Anamnesis, Information about Mother and Pregnancy, Complaints, Auditory Development, Language Development, Motor Development, Simplified Auditory Processing Evaluation and Behavioral Audiological Assessment.

CONCLUSION

The script is essential, given the lack of screening instruments in the literature for central auditory processing in preschool children that thoroughly investigate the entire process that permeates the auditory and language development of children aged 43 to 47 months.

Implications of musical practice in central auditory processing: a systematic review

Introduction

Recent studies have shown that musical practice and training are effective and have the potential to assist in the acquisition and improvement of auditory skills.

Objective

To verify the scientific evidence on the implications of musical practice in central auditory processing.

Methods

A systematic review was carried out in accordance with the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), using the Medline (Pubmed), LILACS, SciELO, BIREME, Scopus and Web of Science databases. The search period for the articles covered the last 5 years (2015–2020), without restriction of language and location. The quality of the articles was assessed, and the review included articles with a minimum score of 6 in a modified literature quality scale.

Results

Initially, 1362 publications were found, of which 1338 were excluded after the title screening, 15 were excluded due to the abstract, with nine articles being analyzed in full and four of them excluded after the analysis, as they did not answer the guiding question proposed for this research. Five articles that met the proposed inclusion criteria were admitted for this research. It was found that in adults, musical ability is associated with better performance of several auditory processing skills, as well as the fact that musical training in children promoted an accelerated maturity of auditory processing and exposure to music facilitated the learning of auditory information in newborns.

Conclusion

Considering the scientific evidence, it was found that the musical experience can improve specific skills of the central auditory processing, regardless of age, optimizing children’s linguistic development.

Central auditory processing in teenagers with non-cholesteatomatous chronic otitis media

Introduction

Evidences of possible effects of early age otitis media with effusion in the central auditory processing, emphasize the need to consider such effects also in subjects with chronic otitis media.

Aim

To investigate and analyze the impact of non-cholesteatomatous chronic otitis media on central auditory processing in teenagers.

Methods

This is a study in which 68 teenagers were recruited, 34 with a diagnosis of non-cholesteatomatous chronic otitis media (study group) and 34 without otological disease history (control group). The evaluation of the subjects consisted of: anamnesis, pure-tone threshold audiometry, speech audiometry and a behavioral test battery for assessment of central auditory processing.

Results

A statistically significant difference was found between the means observed in the study and control groups in all tests performed. An association was found between the control group and subgroups of the study group with unilateral alterations in all tests. An association was shown between the results for the control group and study group for family income, with a greater impact on subjects with a lower income.

Conclusions

Non-cholesteatomatous chronic otitis media affects the central auditory processing in teenagers suffering from the disorder, and monaural low-redundancy hearing is the most affected auditory mechanism. Unilateral conductive changes cause more damage than bilateral ones, and lower family income seems to lead to more changes to the central auditory processing of subjects with non-cholesteatomatous chronic otitis media.

Procedures for central auditory processing screening in schoolchildren

Introduction

Central auditory processing screening in schoolchildren has led to debates in literature, both regarding the protocol to be used and the importance of actions aimed at prevention and promotion of auditory health. Defining effective screening procedures for central auditory processing is a challenge in Audiology.

Objective

This study aimed to analyze the scientific research on central auditory processing screening and discuss the effectiveness of the procedures utilized.

Methods

A search was performed in the SciELO and PUBMed databases by two researchers. The descriptors used in Portuguese and English were: auditory processing, screening, hearing, auditory perception, children, auditory tests and their respective terms in Portuguese. Inclusion criteria: original articles involving schoolchildren, auditory screening of central auditory skills and articles in Portuguese or English. Exclusion criteria: studies with adult and/or neonatal populations, peripheral auditory screening only, and duplicate articles. After applying the described criteria, 11 articles were included.

Results

At the international level, central auditory processing screening methods used were: screening test for auditory processing disorder and its revised version, screening test for auditory processing, scale of auditory behaviors, children's auditory performance scale and Feather Squadron. In the Brazilian scenario, the procedures used were the simplified auditory processing assessment and Zaidan's battery of tests.

Conclusion

At the international level, the screening test for auditory processing and Feather Squadron batteries stand out as the most comprehensive evaluation of hearing skills. At the national level, there is a paucity of studies that use methods evaluating more than four skills, and are normalized by age group. The use of simplified auditory processing assessment and questionnaires can be complementary in the search for an easy access and low-cost alternative in the auditory screening of Brazilian schoolchildren. Interactive tools should be proposed, that allow the selection of as many hearing skills as possible, validated by comparison with the battery of tests used in the diagnosis.
