Neurelec Digisonic（R）SP双耳耳蜗植入体提供了双侧耳蜗植入的替代方案，其允许在单个装置内刺激双侧耳蜗。本前瞻性研究旨在比较一组Neurelec Digisonic（R）SP双耳植入体使用者（表示为BINAURAL组，n = 7）与一组双侧成人人工耳蜗植入体使用者（表示为BILATERAL组，n = 6）的言语感知、声音定位以及健康状况和听力残疾的自我评估。在安静和“鸡尾酒会”噪声中，使用60 dB SPL的单词识别评估言语感知，该噪声通过面向患者的半声场中的五个扬声器传递（信噪比= +10 dB）。声音定位任务是在距离中线-90度和+90度之间定位的五个扬声器中确定声音刺激的来源。使用格拉斯哥福利量表评估健康状况的变化，并使用助听器福利简档评估听力残疾。两组之间的言语感知没有统计学差异，尽管存在有利于BINAURAL组的趋势（BINAURAL和BILATERAL组的平均单词识别百分比：安静时为70 vs. 56.7%，噪音时为55.7 vs. 43.3%）。在声音定位和自我评估健康状况和听力残疾方面的表现也没有显着差异。根据BINAURAL组在检测耳间差异的听力任务中的表现，可以考虑植入Neurelec Digisonic（R）SP双耳植入体以恢复有效的双耳听力。基于这些首次比较结果，该器械似乎提供了与传统双侧人工耳蜗植入术相似的受益，采用了一种新的方法来刺激两条听觉神经。版权所有（c）2013 S.

An alternative to bilateral cochlear implantation is offered by the Neurelec Digisonic (R) SP Binaural cochlear implant, which allows stimulation of both cochleae within a single device. The purpose of this prospective study was to compare a group of Neurelec Digisonic (R) SP Binaural implant users (denoted BINAURAL group, n = 7) with a group of bilateral adult cochlear implant users (denoted BILATERAL group, n = 6) in terms of speech perception, sound localization, and self-assessment of health status and hearing disability. Speech perception was assessed using word recognition at 60 dB SPL in quiet and in a 'cocktail party' noise delivered through five loudspeakers in the hemi-sound field facing the patient (signal-to-noise ratio = +10 dB). The sound localization task was to determine the source of a sound stimulus among five speakers positioned between -90 degrees and +90 degrees from midline. Change in health status was assessed using the Glasgow Benefit Inventory and hearing disability was evaluated with the Abbreviated Profile of Hearing Aid Benefit. Speech perception was not statistically different between the two groups, even though there was a trend in favor of the BINAURAL group (mean percent word recognition in the BINAURAL and BILATERAL groups: 70 vs. 56.7% in quiet, 55.7 vs. 43.3% in noise). There was also no significant difference with regard to performance in sound localization and self-assessment of health status and hearing disability. On the basis of the BINAURAL group's performance in hearing tasks involving the detection of interaural differences, implantation with the Neurelec Digisonic (R) SP Binaural implant may be considered to restore effective binaural hearing. Based on these first comparative results, this device seems to provide benefits similar to those of traditional bilateral cochlear implantation, with a new approach to stimulate both auditory nerves.
