To investigate the postoperative long-term outcomes after an average of 9.2 years following cochlear implantation (CI) in prelingually deafened adults, along with preimplantation factors predicting postoperative outcomes. Twenty-six prelingually deafened adults who underwent CI at >18 years were compared with those who had undergone CI in childhood (<9 years) and were >10 years old. Outcome measures includedhearing thresholds, preoperative and postoperative aided hearing level (HL), speech discrimination score (SDS), and Categories of Auditory Performance (CAP) scores. Correlation analyses were performed on the following: SDS results, aided HL, school attendant status, implant manufacturers, and speech processor models. Improvement was achieved in the aided HL and SDS results, although these results were not better than those of the child group. CAP score was also statistically significantly improved after CI. Statistically significant correlation between the preoperative SDS and postoperative HL with CI results was observed. In other words, the better the preoperative SDS results, the better the postoperative SDS results. Prelingually deafened adults achieved considerable improvement through CI. It is important to understand that patients achieving better hearing with a well-fitted hearing aid and good SDS performance before surgery may be good candidates for CI.
为了调查在人工耳蜗植入（CI）平均 9.2 年后的长期术后结果，以及预测术后结果的术前因素，我们对 26 名在 >18 岁时接受 CI 的语前聋成人进行了研究，这些人与在 >10 岁时接受 CI 的儿童（<9 岁）进行了比较。结果测量包括听力阈值、术前和术后助听听力水平（HL）、言语辨别得分（SDS）和听觉表现类别（CAP）得分。对以下因素进行了相关分析：SDS 结果、助听 HL、学校监护人状态、植入物制造商和言语处理器模型。尽管这些结果并不优于儿童组，但在助听 HL 和 SDS 结果方面均取得了改善。植入 CI 后 CAP 评分也有统计学意义上的显著提高。在术前 SDS 和术后 HL 与 CI 结果之间观察到统计学显著相关性。换句话说，术前 SDS 结果越好，术后 SDS 结果越好。语前聋成年人通过 CI 取得了相当大的改善。重要的是要了解，在手术前使用适配良好的助听器和良好的 SDS 表现获得更好听力的患者可能是 CI 的良好候选者。
