比较在安静、+10 dB信噪比（SNR）和+5 dB SNR条件下，符合人工耳蜗植入（CI）条件的患者术前与术后言语性能的差异。回顾展三级转诊中心。包括来自三组的58名语言障碍后单侧CI接受者：1）在安静时使用AzBio句子符合CI候选标准的人，2）在噪音中在+10 dB SNR但不在安静时，3）和在噪音中在+5 dB SNR但不在安静或+10 dB SNR时。单侧CI。术前和术后1年的语音识别评分。第1组中个体的最佳辅助AzBio语音识别在所有测试条件下均显著改善，第2组和第3组在术后+10和+5 dB SNR测试条件下均显著改善。然而，当单独使用CI进行测试时，虽然第1组和第2组中个体的AzBio语音识别在安静和+10 dB SNR条件下显著改善，但第3组中个体的语音识别在术后任何测试条件下均未发生显著变化。虽然仅在+5 dB SNR条件下有资格获得CI的个体可能从最佳辅助条件下的植入中获得显著益处，但言语理解结果可能更具可变性，因此在植入前无需额外咨询，并需要逐个考虑听力需求和目标。
To compare the difference in pre- to postoperative speech performance of patients qualifying for a cochlear implant (CI) in quiet, +10 dB signal-to-noise ratio (SNR) and +5 dB SNR. Retrospective. Tertiary referral center. Fifty-eight post-lingually deafened, unilateral CI recipients from three Groups were included: 1) those who met CI candidacy criteria with AzBio sentences in quiet, 2) in noise at +10 dB SNR but not in quiet, 3) and in noise at +5 dB SNR but not in quiet or +10 dB SNR. Unilateral CI. Pre- and one year postoperative speech recognition scores. Best-aided AzBio speech recognition of individuals in Group 1 improved significantly for all test conditions and improved significantly for Groups 2 and 3 in the +10 and +5 dB SNR test conditions postoperatively. When tested with their CI alone however, while AzBio speech recognition of individuals in Group 1 and Group 2 improved significantly in the quiet and +10 dB SNR conditions, speech recognition was not significantly changed postoperatively under any testing condition for individuals in Group 3. While individuals qualifying for a CI only in the +5 dB SNR condition may derive significant benefit from implantation in best aided conditions, speech understanding outcomes can be more variable thus warranting additional counseling prior to implantation and case-by-case consideration of listening needs and goals.
