比较单独人工耳蜗（CI）或电声刺激（EAS）器械的急性语音识别，以获得使用Corti器官（OC）与螺旋神经节（SG）频率-位置函数计算的基于位置的映射。11名成人CI接受者的侧壁电极阵列。术后成像用于推导使用OC与SG函数计算的位置标测图。音素识别进行了评估与辅音核辅音（CNC）的话，使用OC与SG基于位置的地图。对于9名单独使用CI的用户，SG图（平均18 rau）的急性音素识别优于OC图（平均9 rau; p=0.071，95% CI [≤-1.2]）的趋势不显著。当分析中包括2名EAS用户时，SG标测图（平均21 rau）的性能显著优于OC标测图（平均7 rau; p=0.019，95% CI [≤-6.2]）。与OC基于位置的映射相比，使用SG频率到位置函数的更好的音素识别可以指示信息的更自然的音调位置对准。目前正在进行一项前瞻性随机研究，以评估单独CI和EAS器械中使用SG频率-位置功能进行基于位置的标测的纵向结局。
To compare acute speech recognition with a cochlear implant (CI) alone or electric-acoustic stimulation (EAS) device for place-based maps calculated with an organ of Corti (OC) versus a spiral ganglion (SG) frequency-to-place function. Eleven adult CI recipients of a lateral wall electrode array. Postoperative imaging was used to derive place-based maps calculated with an OC versus SG function. Phoneme recognition was evaluated with consonant-nucleus-consonant (CNC) words presented using an OC versus a SG place-based map. For the 9 CI-alone users, there was a non-significant trend for better acute phoneme recognition with the SG map (mean 18 rau) than the OC map (mean 9 rau; p=0.071, 95% CI [≤−1.2]). When including the 2 EAS users in the analysis, performance was significantly better with the SG map (mean 21 rau) than the OC map (mean 7 rau; p=0.019, 95% CI [≤−6.2]). Better phoneme recognition with the SG frequency-to-place function could indicate more natural tonotopic alignment of information compared to the OC place-based map. A prospective, randomized investigation is currently underway to assess longitudinal outcomes with place-based mapping in CI-alone and EAS devices using the SG frequency-to-place function.
