A importância da análise perceptivo-auditiva em indivíduos com hipotireoidismo congênito: uma revisão sistemática

Abstract

OBJECTIVE: To investigate the importance of carrying out vocal perceptual analysis in children with congenital hypothyroidism in scientific productions. METHOD: The most relevant studies published during the period from 2008 to 2021 were analyzed, using the Virtual Health Library (VHL), Scientific Electronic Library Online (Scielo), U.S. National Library of Medicine (PUBMED/MEDLINE) databases as references, Cochrane Library: Cochrane Reviews, EMBASE. The search strategy used the following combinations: congenital hypothyroidism and voice; congenital hypothyroidism and child; congenital hypothyroidism and child and voice; vocal perceptual analysis in children with congenital hypothyroidism. To identify the study designs, the following terms were used: review and meta-analysis. Regarding quality and risk of bias, the study was evaluated by three independent judges, who used the Newcastle-Ottawa scale checklist, thus establishing the result of the same. RESULTS: Initially, 124 studies were located that referred to congenital hypothyroidism and dysphonia separately. Of these, after evaluating the titles, 50 articles were selected that were related to the combinations of the present review. 47 were excluded that did not associate HC with vocal problems. Thus, 3 studies remained for the next stage of the review. In the second stage, the abstracts were evaluated and 1 article published in PUBMED and MEDLINE and 2 published in SciELO were selected. CONCLUSION: Further studies are required to clarify a possible association between vocal disorders and hypothyroidism, which can cause myxedema in the larynx and, consequently, dysphonia, and abnormal development and communication.
