Reabilitação de perdas auditivas unilaterais por próteses auditivas implantáveis: revisão sistemática

Abstract

Introduction:The binaural hearing is the proper condition that allows the listener the depth dimension and sonority necessary to the perception of the soundworld. Objective: To determine, through a systematic review, the benefits that implantable hearing aids bring to adult individuals who have unilateral hearing loss in terms of localization of sound source and speech recognition in the presence of noise. Selection criteria: Survey participants over 18 years old with unilateral hearing loss, who used implantable hearing aid bone anchored hearing aids or cochlear implantation) and who had been submitted to the evaluation of the location of the sound source or performance of speech recognition in the presence of noise before and After implantation. Results: Of the 21 articles analyzed, seven were experimental; six were prospective, three descriptive, four case series and one case study. Conclusion: Despite the great clinical heterogeneity observed among the studies that evaluated the auditory rehabilitation of patients with unilateral hearing loss, it is possible to conclude that the cochlear implant provides better results both for the localization of the sound source and for speech recognition in the presence of noise.Keywords: Hearing loss, Unilateral; Cochlear implantation; Bone conduction; Hearing aids RESUMO Introdução: A audição binaural é a condição adequada que permite ao ouvinte a dimensão de profundidade e sonoridade necessárias à percepção do mundo sonoro. Objetivo: Determinar, por meio de uma revisão sistemática, quais os benefícios que as próteses auditivas implantáveis trazem para indivíduos adultos que possuem perda auditiva unilateral, no que se refere às habilidades de localização da fonte sonora e do reconhecimento de fala na presença do ruído.

Hearing rehabilitation of children and adolescents with unilateral hearing loss

“…A high clinical variability was found in regards to the adopted intervention when it comes to auditory rehabilitating patients with UHL and, therefore, one can infer that such cases represent a challenge to doctors and audiologists, which is more evidenced when the target-public is of children (26) . As observed in Figure 2, the majority of the sample (52.9%) received indication of electronic devices, which for 15 (44.1%) the HA was indicated and the CROS was chosen for three (8.8%) of them.…”

Perda auditiva unilateral e assimétrica na infância

“…Thus, there is a growing increase on discussions about the possibilities and indications of intervention measures in unilateral and asymmetric hearing loss in childhood, such as implantable hearing aids and, in the international scientific community, the cochlear implant, in addition to the Hearing Aid (HA)and the adaptation Contralateral Routing of Signal (CROS) (6)(7)(8)(9) .…”
