Partial deafness cochlear implantation and electric-acoustic stimulation have proven to be a useful method of treating adults with a ski-slope type hearing loss. Good hearing preservation and speech perception outcomes have been reported. This study aims to assess partial deafness cochlear implantation in children.
Nine children, ranging in age from 4.2 to 12 years, received a cochlear implant following the round window surgical technique for partial deafness cochlear implantation. Hearing preservation was assessed by pure-tone audiometry and speech perception outcomes were measured using monosyllable word tests in quiet and noise. Data are available for most children up to a period of 1 year.
Hearing could be preserved partially in all cases, however, one child does not have sufficient preservation to make use of electric-acoustic stimulation. The eight children with sufficiently preserved hearing either use the natural low frequency hearing in combination with a cochlear implant to hear or use the DUET combined hearing system. Speech perception tests showed improvement in quiet and noise over time.
Results suggest that partial deafness cochlear implantation is a viable treatment method in children. However, surgery should only be conducted by an experienced surgeon and parents need to be carefully counselled about the risks and benefits of partial deafness cochlear implantation.
部分性聋人工耳蜗植入及电声刺激已被证明是治疗具有斜坡型听力损失成人的一种有效方法。已有报道称其听力保留良好且言语感知结果良好。本研究旨在评估儿童部分性聋人工耳蜗植入情况。
9名年龄在4.2至12岁之间的儿童接受了采用圆窗手术技术的部分性聋人工耳蜗植入。通过纯音听力测定评估听力保留情况，并使用安静和噪声环境下的单音节词测试测量言语感知结果。大多数儿童的数据可获取长达1年的时间。
所有病例听力均可部分保留，然而，有1名儿童听力保留不足，无法使用电声刺激。8名听力保留充分的儿童要么将自然低频听力与人工耳蜗结合使用来聆听，要么使用DUET联合听力系统。言语感知测试显示，随着时间推移，安静和噪声环境下的表现均有改善。
结果表明，部分性聋人工耳蜗植入对儿童是一种可行的治疗方法。然而，手术应由经验丰富的外科医生进行，且需要就部分性聋人工耳蜗植入的风险和益处对家长进行仔细咨询。
