ABSTRACT
Abstract

Introduction:

Despite recent advancement in the prediction of cochlear implant outcome, the benefit of bilateral procedures compared to bimodal stimulation and how we predict speech perception outcomes of sequential bilateral cochlear implant based on bimodal auditory performance in children remain unclear.

Objectives:

This investigation was performed (1) to determine the benefit of sequential bilateral cochlear implant and (2) to identify the associated factors for the outcome of sequential bilateral cochlear implant.

Methods:

Observational and retrospective study. We retrospectively analyzed 29 patients with sequential cochlear implant following bimodal-fitting condition. Audiological evaluations were performed; the categories of auditory performance scores, speech perception with monosyllable and disyllables words, and the Korean version of Ling. Audiological evaluations were performed before sequential cochlear implant with the bimodal fitting condition (CI1 + HA) and one year after the sequential cochlear implant with bilateral cochlear implant condition (CI1 + CI2). The good performance group (GP) was defined as follows; 90% or higher in monosyllable and bisyllable tests with auditory-only condition or 20% or higher improvement of the scores with CI1 + CI2. Age at first implantation, inter-implant interval, categories of auditory performance score, and various comorbidities were analyzed by logistic regression analysis.

Results:

Compared to the CI1 + HA, CI1 + CI2 provided significant benefit in categories of auditory performance, speech perception, and Korean version of Ling results. Preoperative categories of auditory performance scores were the only associated factor for being GP (odds ratio = 4.38, 95% confidence interval - 95% = 1.07-17.93, p = 0.04).

Conclusions:

The children with limited language development in bimodal condition should be considered as the sequential bilateral cochlear implant and preoperative categories of auditory performance score could be used as the predictor in speech perception after sequential cochlear implant.
RESUMO
Resumo

Introdução:

Apesar dos avanços recentes na predição do resultado do implante coclear, ainda não está claro o benefício do procedimento bilateral em comparação com a estimulação bimodal e como podemos prever resultados de percepção da fala com implante coclear bilateral sequencial com base no desempenho auditivo bimodal em crianças.

Objetivos:

Este estudo foi realizado para 1) Determinar o benefício do implante coclear bilateral sequencial e 2) Identificar os fatores associados com o resultado do implante bilateral sequencial.

Método:

Estudo observacional e retrospectivo. Analisamos retrospectivamente 29 pacientes com implantes sequenciais após a adaptação bimodal. Avaliações audiológicas foram realizadas; os escores das categorias de desempenho auditivo, a percepção da fala com palavras monossílabas e dissílabas e a versão coreana de Ling. As avaliações audiológicas foram realizadas antes do implante sequencial com o ajuste bimodal (IC1 + AH) e um ano após o implante coclear sequencial com implante bilateral (IC1 + IC2). O grupo com bom desempenho (BD) foi definido da seguinte forma 90% ou mais em testes com monossílabos e dissílabos com condição apenas auditiva ou melhoria de 20% ou mais dos escores com IC1 + IC2. A idade no primeiro implante, o intervalo interimplante, o escore categorias de desempenho auditivo e as diversas comorbidades foram analisadas através de análise de regressão logística.

Resultados:

Em comparação com o IC1 + AA, IC1 + IC2 demonstraram benefícios significativos nos escores categorias de desempenho auditivo, percepção da fala e a versão coreana de Ling. Os escores de categorias de desempenho auditivo pré-operatórios foram o único fator associado para ser do grupo BD (odds ratio - OR = 4,38, intervalo de confiança de 95% - IC 95% = 1,07-17,93, p = 0,04).

Conclusões:

As crianças com desenvolvimento limitado de linguagem em condição bimodal devem ser consideradas, pois o implante coclear bilateral sequencial e o escore pré-operatório das categorias de desempenho auditivo poderiam ser usados como preditores na percepção da fala após implante sequencial.
