| Sumario: | Many studies have discussed the factors influencing hearing outcomes after cochlear implantation, but few have addressed improvements in speech perception for these patients over time. To investigate the relationship between preoperative factors and the pattern of longitudinal improvement in speech perception following cochlear implantation (CI). This study enrolled 83 patients (96 ears) who underwent CI at Shinshu University Hospital. The patients were assessed up to 12 months after CI by a monosyllable test, and showed either delayed improvement (DI), early improvement (EI), or stable improvement (SI) when compared with their preoperative score. Eight preoperative variables were also examined for their effects on speech perception over time. The DI, EI, SI groups comprised 35.4%, 43.8%, and 20.8% of all patients, respectively. Patients in the DI group were older at surgery than those in the EI and SI groups, and their onset age were also older than that in the SI group. No other preoperative variables showed significant differences across the three groups. Our findings revealed that age at implantation and age at onset of hearing loss significantly affected the improvement pattern of speech perception. Age may be useful in predicting recovery of speech perception after CI. 背景：多项研究讨论了影响人工耳蜗植入术后听力结果的因素, 但很少有人解决过这些患者言语感知的改善。 目的：探讨术前因素与人工耳蜗植入 (CI) 后言语感知的纵向改善模式之间的关系。 材料和方法：本研究纳入了在信州大学医院接受 CI 的 83 名患者（96只耳）。 患者在 CI 后 12 个月内通过单音节测试得到评估, 与他们的术前评分相比, 表现出延迟改善 (DI)、早期改善 (EI) 或稳定改善 (SI)。 还检查了八个术前变量对言语感知的影响。 结果：DI组、EI组、SI 组分别占所有患者的 35.4%、43.8% 和 20.8%。在手术时, DI 组患者比 EI组 和 SI 组年龄大, 并且他们的发病年龄也比 SI 组大。 三组之间没有其它术前变量表现出显著差异。 结论和意义：我们的研究结果表明, 植入年龄和听力损失发病年龄显著影响言语感知的改善模式。 年龄可能用于预测 CI 后言语感知的恢复。 |
