This study investigated the speech perception of cochlear implant (CI) recipients with measurable preoperative ipsilateral speech perception. These data should support improved individual counselling of CI candidates.
Pre- and postoperative speech audiometric parameters were analyzed, including maximum score for phonemically balanced words (PB) and monosyllabic score at a normal conversational level of 65 dB, with hearing aids one hand and CI on the other. Data of 284 experienced adult CI wearers were grouped and evaluated in terms of preoperative PB.
The preoperative PB was exceeded by the postoperative monosyllabic score in 96% of cases. The overall median postoperative score was 72.5%. The groups with preoperative PB > 0% showed significantly better speech perception scores with CI than the group with PB = 0 %. Median improvement compared to the preoperative monosyllabic score with hearing aids was 65 percentage points, independent of preoperative PB.
The preoperatively measured PB may be used as a predictor for the minimum speech perception obtained with CI. This is of high clinical relevance for CI candidates with a PB above zero.
本研究调查了术前同侧言语感知能力可测量的人工耳蜗（CI）植入者的言语感知情况。这些数据应有助于改善对CI候选者的个性化咨询。
分析术前和术后言语听力测定参数，包括音素平衡词（PB）的最高分和在65dB正常对话水平下的单音节得分，分别使用助听器和CI时的情况。对284名经验丰富的成年CI佩戴者的数据按术前PB进行分组和评估。
96%的病例术后单音节得分超过术前PB。术后总体中位数得分是72.5%。术前PB＞0%的组使用CI时的言语感知得分明显高于PB = 0%的组。与术前使用助听器时的单音节得分相比，中位数改善为65个百分点，与术前PB无关。
术前测量的PB可作为CI获得的最低言语感知的预测指标。这对PB高于零的CI候选者具有高度临床相关性。
