Abstract:
Objective: To investigate the development of auditory speech perception and spatial hearing abilities within one year after cochlear implantation in preschool prelingual deaf children and the relationship between the two abilities. Methods: This retrospective study analyzed 31 preschool children with an average age of (2.3±1.2) years. All cases were assessed at pre-implant, 6 months and 12 months post-implant using the Infant-toddler Meaningful Auditory Integration Scale (IT-MAIS), the Meaningful Auditory Integration Scale (MAIS) and the Mandarin Early Speech Perception test (MESP) to evaluate their listening and speech perception abilities, and using the Speech,Spatial,and Other Qualities of Hearing Scale for Parents (SSQ-P) questionnaires to evaluate their speech perception and spatial hearing abilities. SPSS 23.0 was used for the statistical analysis. Results: All children performed better at 6 months and 12 months post-implant with IT-MAIS/MAIS, MESP than pre-implant, and the scoring rate continued to improve, with a significant difference (P<0.01). For the SSQ-P (Speech) and SSQ-P (Spatial) scores, the mean scores of pre-implant were (0.9±0.2) points and (0.8±0.3) points, those of 6 months post-implant were (4.6±0.2) and (2.6±0.3), and 12 months post-implant were (6.2±0.2) and (6.3±0.3), the scores of the two groups were significantly different at pre-implant, 6 months and 12 months post-implant (P<0.01). The growth rate of SSQ-P (Spatial) from pre-implant to 12 months post-implant was 675.3%, and the growth rate from 6 months post-implant to 12 months post-implant was 140.6%, the growth rate showed an significant increase compared with IT-MAIS/MAIS, MESP and SSQ-P (Speech).SSQ-P (Speech) and SSQ-P (Spatial) scores were moderate correlation at 12 months post-implant(r=0.465, P=0.008). Conclusions: Within one year after cochlear implantation, listening, speech perception and spatial hearing abilities of preschool prelingual deaf children could show a comprehensive, continuous and significant progress as the implantation time increasing. The growth rate of spatial hearing is greater than that of speech perception at 12 months post-implant, and the spatial hearing could still show rapid development characteristics after 6 months post-implant. 目的： 探讨低龄人工耳蜗植入术后儿童言语感知和空间听觉能力发育规律及二者之间的关系。 方法： 31例人工耳蜗植入术后儿童，男16例、女15例，年龄（2.3±1.2）岁（x¯±s，下同），分别在术前、开机6个月以及开机12个月，应用普通话婴幼儿有意义听觉整合量表（Infant-toddler Meaningful Auditory Integration Scale，IT-MAIS）/普通话有意义听觉整合量表（Meaningful Auditory Integration Scale，MAIS）和普通话早期言语感知测试（Mandarin Early Speech Perception test，MESP）评估听觉能力和言语感知能力发展，应用言语空间听觉质量量表父母版问卷（Speech，Spatial，and Other Qualities of Hearing Scale for Parents，SSQ-P）评估空间听觉能力的发展。应用SPSS 23.0软件进行统计学分析。 结果： 随开机时间延长，31例人工耳蜗植入儿童IT-MAIS/MAIS、MESP得分率持续提高，术前、开机6个月及开机12个月三个时间节点的得分率差异均有统计学意义（P值均<0.01）。SSQ-P（Speech）和SSQ-P（Spatial）得分：术前分别为（0.9±0.2）、（0.8±0.3）分，开机6个月为（4.6±0.2）、（2.6±0.3）分，开机12个月为（6.2±0.2）、（6.3±0.3）分，两项得分在术前、开机6个月、开机12个月三个时间节点差异均有统计学意义（P值均<0.01）。SSQ-P（Spatial）从术前至开机12个月的增长率为675.3%、开机6个月至12个月期间的增长率为140.6%，明显高于IT-MAIS/MAIS、LV-MESP及SSQ-P（Speech）的增长率。CI开机后12个月，SSQ-P（Speech）得分与SSQ-P（Spatial）得分呈中度相关（r=0.465，P=0.008）。 结论： 人工耳蜗植入术后儿童随开机时间延长，其听能、言语感知能力、空间听觉能力均呈现持续性显著进步。开机12个月时空间听觉能力增长率大于言语感知能力，且空间听觉能力在人工耳蜗开机6个月后仍呈现快速发育特点。.
