The aim of this study is to compare the results of auditory perception tests and speech sound evaluations with electrode array length in patients with Mondini deformity.
The study included 14 patients who underwent cochlear implantation and radiologically confirmed Mondini deformity between 2007 and 2021 in our clinic. While 7 patients received standard electrode arrays from the MED-EL brand, the remaining 7 received shortened electrode arrays from the MED-EL brand. Differences in auditory perception, articulation, and speech intelligibility between the two groups were examined. Auditory perception tests were administered to these patients preoperatively and at least 2 years after cochlear implant surgery. The patients' auditory perception performance was evaluated using single, double, and triple closed-set word tests (MTP-3, MTP-6, MTP-12), two-syllable open-set word test, Glendonald Auditory Screening Procedure (GASP) tests for articulation, Phonemic Synthesis Test (SST) for phonemic knowledge, and Speech Intelligibility Rating (SIR) test for speech intelligibility.
Both groups did not show statistically significant differences in auditory perception tests (MTP-3, MTP-6, MTP-12, two-syllable open-set word test), speech sound tests (SST), and speech intelligibility test (SIR). Significant improvement was observed in all tests in both groups when compared preoperatively and postoperatively.
No significant difference was observed in auditory perception and speech sound tests between groups with short and standard electrode arrays in patients with Mondini deformity. The option of using short electrode arrays during implantation in patients with Mondini deformity can be preferred without doubt in terms of outcomes.
本研究旨在比较蒙迪尼畸形患者听觉感知测试结果及语音评估结果与电极阵列长度之间的关系。
本研究纳入了2007年至2021年期间在我院接受人工耳蜗植入且经放射学确诊为蒙迪尼畸形的14例患者。其中7例患者接受了MED-EL品牌的标准电极阵列，其余7例接受了MED-EL品牌的缩短电极阵列。对两组患者的听觉感知、清晰度及言语可懂度差异进行了检测。在这些患者术前及人工耳蜗植入术后至少2年进行听觉感知测试。采用单字、双字和三字封闭集词汇测试（MTP-3、MTP-6、MTP-12）、双音节开放集词汇测试、用于清晰度检测的格伦多纳德听觉筛查程序（GASP）测试、用于音素知识检测的音素合成测试（SST）以及用于言语可懂度检测的言语可懂度评分（SIR）测试对患者的听觉感知表现进行评估。
两组在听觉感知测试（MTP-3、MTP-6、MTP-12、双音节开放集词汇测试）、语音测试（SST）及言语可懂度测试（SIR）方面均未显示出统计学上的显著差异。与术前相比，两组在所有测试中术后均观察到显著改善。
蒙迪尼畸形患者中，使用短电极阵列组与标准电极阵列组在听觉感知和语音测试方面未观察到显著差异。就结果而言，蒙迪尼畸形患者植入时使用短电极阵列这一选择无疑是更可取的。
