The reliable prediction of cochlear implant (CI) speech perception outcomes is highly relevant and can facilitate the monitoring of postoperative hearing performance. To date, multiple audiometric, demographic, and surgical variables have shown some degree of correlation with CI speech perception outcomes. In the present study, postsurgical acoustic and electric hearing thresholds that are routinely assessed in clinical practice were compared to CI speech perception outcomes in order to reveal possible markers of postoperative cochlear health. A total of 237 CI recipients were included in this retrospective monocentric study. An analysis of the correlation of postoperative pure-tone averages (PTAs) and electric CI fitting thresholds (T-/C-levels) with speech perception scores for monosyllabic words in quiet was performed. Additionally, a correlation analysis was performed for postoperative acoustic thresholds in intracochlear electrocochleography (EcochG) and speech recognition scores in a smaller group ( = 14). The results show that neither postoperative acoustic hearing thresholds nor electric thresholds correlate with postoperative speech perception outcomes, and they do not serve as independent predictors of speech perception outcomes. By contrast, the postoperative intracochlear total EcochG response was significantly correlated with speech perception. Since the EcochG recordings were only performed in a small population, a large study is required to clarify the usefulness of this promising predictive parameter.
人工耳蜗（CI）言语感知结果的可靠预测具有高度相关性，并且有助于监测术后听力表现。迄今为止，多种听力测定、人口统计学和手术变量已显示出与CI言语感知结果存在一定程度的相关性。在本研究中，将临床实践中常规评估的术后声学和电听觉阈值与CI言语感知结果进行比较，以揭示术后耳蜗健康的可能标志物。本项回顾性单中心研究共纳入了237名CI接受者。对术后纯音平均听阈（PTA）和CI电刺激阈值（T-/C级）与安静环境下单音节词言语感知分数之间的相关性进行了分析。此外，对较小一组（n = 14）的耳蜗内电诱发听性脑干反应（EcochG）术后声学阈值与言语识别分数进行了相关性分析。结果表明，术后声学听阈和电刺激阈值均与术后言语感知结果无关，且它们不能作为言语感知结果的独立预测指标。相比之下，术后耳蜗内EcochG总反应与言语感知显著相关。由于EcochG记录仅在少数人群中进行，因此需要开展大规模研究以阐明这一有前景的预测参数的实用性。
