Impacto da expansão rápida da maxila na produção do som da fala: uma revisão sistemática

| Resumo: | Introduction: Maxillary expanders are positioned centrally on the palate. Thus, these appliances might interfere on tongue articulation and impact negatively the speech of patients undergoing rapid maxillary expansion (RME). Objectives: To evaluate changes on speech sound production in children, adolescents and adults treated with RME. Material and methods: Two reviewers independently and blindly performed an electronic search. The articles were pre-selected based on the title and abstract. After reading the fulltext articles, the studies that met the eligibility criteria were included. A manual search was performed by examining the references of each selected article. The ROBINS-I tool was used to qualitatively assess the selected studies. Results: Ten articles were selected, and the risk of bias ranged from moderate to critical. The studies showed methodological limitations related to the selection of eligibility criteria, lack of randomization and allocation concealment of participants, lack of control groups, lack of assessment blinding and lack of standardization of the type of expander used, the amount of expansion and the follow-up time. The studies found a tendency of RME promotes significant changes in speech. However, the negative impact on speech sounds production seems to be temporary, tending to improve during the retention phase and returning to normal after the maxillary expander removal. Conclusion: Rapid maxillary expansion seems to promote temporary changes in speech sound production that return to normality after expander removal. However, the quality of the evidence is limited, and well-conducted randomized clinical trials are necessary to better elucidate these effects. |
