Efeitos da expansão rápida de maxila na audição: revisão sistemática da literatura

Abstract

Purpose: Verifying the effects of rapid maxillary expansion on hearing.Research strategy: The search was conducted in the bibliographic collection of the electronic databases MEDLINE, SciELO and Bibliografia Brasileira de Odontologia (BBO) in January 2016. The keywords used for the research were: "hearing loss", "hearing", "rapid maxillary expansion" and "palatal expansion technique". Selection criteria: Articles in Portuguese, English and Spanish were selected, published up to January 2016, without initial date limitation. Studies related to the rapid maxillary expansion on hearing topic were included in this systematic review. Results: The research strategy resulted in the selection of eight articles, which were classified as clinical trials. The studies explains that the rapid maxillary expansion performed on children and/or teenagers improves hearing thresholds and acoustic impedance measurements. Conclusion: The rapid maxillary expansion caused hearing improvement, despite the methodological limitations and diversity of the analyzed studies.

Produção Consonantal E Características Dimensionais Do Palato Duro Em Pessoas Com Síndrome De Down

“…O ortodontista pode trabalhar juntamente com o fonoaudiológo usando dispositivos orais de forma preventiva auxiliando na reabilitação neuromotora da região oral. Bem como com uso de terapia ortopédica de aumento transversal de palato que acarreta melhora na ventilação nasal, na apneia obstrutiva do sono, ajuda na prevenção de otite média restaurando a função da tuba auditiva e acomodação da língua REY, 2013;BUENO et al, 2016). Sugerimos incluir nos programas de saúde pública, medidas profiláticas e de promoção da saúde que tenham caráter multidiscplinar, visando sempre ao tratamento precoce de alterações estruturais e funcionais do SE das pessoas com SD, principlamente em período de crescimento.…”

“…Após a correção ortodôntica, os problemas de fala desaparecem ou são minimizados (PEREIRA et al, 2005). Com a terapia ortopédica de aumento transversal de palato ocorre a melhora na ventilação nasal, na apneia obstrutiva do sono, ajuda na prevenção de otite média restaurando a função da tuba auditiva e acomodação da língua REY, 2013;BUENO et al, 2016).…”

Unusual systemic and nondental effects of maxillary expansion therapy: A comprehensive and updated review of literature

“…The recent scientific literature pertaining to RME for the correction of maxillary/palatal deficiency has highlighted one of the significant nondental effects, that is, hearing improvement in middle-ear disorders/conductive hearing loss disorders in children and adolescent patients. [ 1 2 3 ] Findings such as constricted maxilla/palate and hearing problems associated with Eustachian tubes, the middle ear, and mouth breathing have been previously described in the existing literature. [ 1 2 3 ] A link between conductive hearing loss and maxillary deficiency in patients with high palatal form and posterior crossbite has been reported in scientific literature.…”

“…Resolution of the middle ear infection and hearing impairment/loss has been described in studies. [ 1 2 3 ] It has been reported that expansion of the constricted palate impacts the auditory anatomic area of the skull (Eustachian tube, i.e. tympanic cavity to the nasopharynx).…”
