Title in English
Evolution of speech perception in patients with ossified cochlea and short array cochlear implant
Keywords in English
Cochlear Implant
Short array
Speech perception
Abstract in English
Purpose. To report the speech perception of users of cochlear implants (CI) with short array, indicated as rehabilitation in patients with severe to profound deafness, especially when there is cochlear ossification. In these cases, with reduced intracochlear patency, total insertion becomes more difficult, requiring the use of this type of electrode (15 mm). Few studies have been published to evaluate auditory performance in these patients, presenting controversial audiological results. Methods. A retrospective analysis of medical records of patients who underwent surgery for cochlear implantation with short electrode, between 2009 and 2020, at the Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo (HRAC-USP) was carried out. Results. There was performance evolution in the speech perception tests in the data analysis. Meningitis and congenital hearing loss were the main indications for CI in the sample. Conclusion. CI with a short lead is an alternative in the management of patients with a history of cochlear ossification and severe or profound sensorineural hearing loss. Significance. To demonstrate the evolution of speech perception tests with short array cochlear implant in patients with or without ossified cochlea and its characteristics for application in clinical practice.

Abstract in Portuguese
Objetivo. Relatar a percepção de fala dos usuários de implante coclear com eletrodo curto, indicado como reabilitação em pacientes com surdez severa a profunda, especialmente quando houver ossificação coclear. Nesses casos, com redução da luz intracoclear, a inserção total se torna mais difícil, com a necessidade do uso desse tipo de eletrodo (15 mm). Poucos estudos foram publicados para avaliar o desempenho auditivo nesses pacientes, apresentando resultados audiológicos, até o momento, controversos. Metodologia. Procedeu-se análise retrospectiva de prontuários de pacientes submetidos à cirurgia para implante coclear com eletrodo curto, entre 2009 e 2020, no Hospital de Reabilitação de Anomalias Craniofaciais da USP. Resultados. Houve evolução de desempenho nos testes de percepção de fala na análise dos dados. Meningite e perda auditiva congênita foram as principais etiologias de indicação de IC na amostra. Conclusão. O IC com eletrodo curto é uma alternativa no manejo de pacientes com história de ossificação coclear e perda auditiva neurossensorial severa ou profunda.
