(1) To survey the use of bimodal stimulation by prelingually deaf children receiving unilateral cochlear implantation and (2) to investigate demographic and audiologic factors explaining the use of bimodal stimulation.
Cross-sectional survey.
Tertiary care institution.
The study included 44 unilaterally implanted prelingually deaf children from a single institution, with a minimum follow-up of 1 year. During routine follow-up visits, an examiner interviewed parents on their children's use of bimodal stimulation. At the same time, residual hearing and hearing aid gain in the contralateral ear were assessed.
Approximately half of patients (52%) used bimodal stimulation. On average, bimodal users showed better mean unaided and aided thresholds than nonbimodal users (P < .001). A mean 250- to 500-Hz unaided threshold ≤90 dB HL in the contralateral, nonimplanted ear was associated with a higher probability of bimodal use (P = .008). Parental satisfaction with the contralateral hearing aid was inversely correlated with mean 125- to 500-Hz and 1000- to 4000-Hz unaided thresholds (P < .001) and mean 250- to 500-Hz and 1000- to 4000-Hz aided thresholds (P < .001).
A mean 250- to 500-Hz unaided threshold ≤90 dB HL is associated with a higher probability of bimodal use by prelingually deaf children. Better residual hearing is associated with a higher degree of parental satisfaction with the contralateral hearing aid. This information could be useful to counsel parents of prelingually deaf children, when deciding between bimodal stimulation and simultaneous bilateral cochlear implantation.
（1）调查接受单侧人工耳蜗植入的语前聋儿童对双模式刺激的使用情况；（2）研究解释双模式刺激使用情况的人口统计学和听力学因素。
横断面调查。
三级医疗机构。
本研究纳入了来自单一机构的44名单侧植入人工耳蜗的语前聋儿童，随访时间至少为1年。在常规随访期间，一名检查人员就其孩子对双模式刺激的使用情况采访了家长。与此同时，评估了对侧耳的残余听力和助听器增益。
约一半的患者（52%）使用双模式刺激。平均而言，使用双模式刺激的患者在未佩戴助听器和佩戴助听器时的平均听阈比未使用双模式刺激的患者更好（P <.001）。对侧未植入耳的250至500Hz平均未佩戴助听器听阈≤90dB HL与更高的双模式刺激使用概率相关（P =.008）。家长对侧助听器的满意度与125至500Hz和1000至4000Hz的平均未佩戴助听器听阈呈负相关（P <.001），与250至500Hz和1000至4000Hz的平均佩戴助听器听阈也呈负相关（P <.001）。
250至500Hz平均未佩戴助听器听阈≤90dB HL与语前聋儿童更高的双模式刺激使用概率相关。更好的残余听力与家长对侧助听器的更高满意度相关。这些信息在为语前聋儿童的家长在双模式刺激和同期双侧人工耳蜗植入之间做出决策时提供咨询可能会有所帮助。
