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. 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. 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 (<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 (<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(=0.465, =0.008). 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.
探讨学龄前语前聋儿童人工耳蜗植入术后1年内听觉言语感知和空间听觉能力的发展情况以及二者之间的关系。本回顾性研究分析了31例平均年龄为（2.3±1.2）岁的学龄前儿童。所有病例在植入前、植入后6个月和12个月时，使用婴幼儿有意义听觉整合量表（IT-MAIS）、有意义听觉整合量表（MAIS）和普通话早期言语感知测试（MESP）评估其听觉和言语感知能力，使用家长版言语、空间及其他听觉质量量表（SSQ-P）问卷评估其言语感知和空间听觉能力。采用SPSS 23.0进行统计分析。所有儿童在植入后6个月和12个月时，IT-MAIS/MAIS、MESP得分均高于植入前，且得分率持续提高，差异有统计学意义（<0.01）。对于SSQ-P（言语）和SSQ-P（空间）得分，植入前平均得分分别为（0.9±0.2）分和（0.8±0.3）分，植入后6个月分别为（4.6±0.2）分和（2.6±0.3）分，植入后12个月分别为（6.2±0.2）分和（6.3±0.3）分，两组在植入前、植入后6个月和12个月时得分差异均有统计学意义（<0.01）。SSQ-P（空间）从植入前到植入后12个月的增长率为675.3%，从植入后6个月到植入后12个月的增长率为140.6%，与IT-MAIS/MAIS、MESP和SSQ-P（言语）相比，增长率显著增加。植入后12个月时，SSQ-P（言语）和SSQ-P（空间）得分呈中度相关（=0.465，=0.008）。人工耳蜗植入术后1年内，学龄前语前聋儿童的听觉、言语感知和空间听觉能力随植入时间增加可呈现全面、持续且显著的进步。植入后12个月时，空间听觉的增长率大于言语感知，且植入后6个月后空间听觉仍可呈现快速发展的特点。
