Evolution of speech perception in patients with ossified cochlea and short array cochlear implant

Abstract

Background: Short array cochlear implant is 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, presenting controversial audiological results.Aims/Objectives: To report the speech perception of users of cochlear implants (CI) with short array. Material and Methods: A retrospective analysis of medical records of patients who underwent surgery for cochlear implantation with a short array, 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 array 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.

Chinese Abstract

背景：短阵列人工耳蜗适用于重度至极重度耳聋患者的康复, 尤其是在耳蜗骨化的情况下。 在这些病例中, 随着耳蜗内通畅性的降低, 完全插入变得比较困难, 需要使用这种类型的电极（15mm）。已发表的评估听觉表现的研究很少。这些研究提出有争议的听力学结果。

目的：报告短阵列人工耳蜗 (ci) 使用者的言语感知。

材料和方法：对 2009 年至 2020 年间在圣保罗大学颅面异常康复医院 (hRac-UsP) 接受短阵列人工耳蜗植入手术的患者的病历进行回顾性分析。

结果：数据分析中, 语音感知测试可见性能改善。 脑膜炎和先天性听力损失是样本中人工耳蜗的主要适应症。

结论： 具有短阵列的人工耳蜗是治疗有耳蜗骨化病史和严重或极重度感音神经性听力损失的患者的另一种选择。

意义：展示短阵列人工耳蜗植入有或无骨化耳蜗患者后, 言语感知测试的改善, 及其在临床实践中的应用特点。
