目的：确定人工耳蜗植入后，当听觉和视觉语音信息可用时，先天性耳聋的成年人是否获得改善的语音感知。研究设计：重复测量单一受试者在单独视觉、单独听觉和视听条件下的语音感知分析。设置：神经耳病学私人诊所和研究机构。受试者：8名患有严重先天性双侧听力损失的成年人，接受人工耳蜗植入术（年龄18-55岁）在1995年和2002年之间，并有至少1年的植入经验。主要结果测量：听觉，视觉和视听言语感知。结果：言语感知得分的中位数如下：单独视觉，25.9%（范围：12.7-58.1%）;单独听觉，5.2%（范围：0-49.4%）;视听，50.7%（范围：16.5-90.8%）。8名受试者中有7名在视听条件下的表现与单独使用听觉或视觉条件下的表现一样好或更好。三名受试者的视听分数大于预期从一个简单的加性效应的信息从单独的视觉和视觉条件单独，这表明一个超加性效应的组合单独的视觉和视觉信息。三名受试者有一个简单的添加剂效应的言语知觉在audiovisual condition.Conclusion：一些先天性epidened受试者谁接受植入作为成年人有显着的收益时，从人工耳蜗植入和视觉信息唇读的听觉信息的言语知觉。这项研究表明，一些先天性耳聋的成年人能够整合人工耳蜗植入体提供的听觉信息（尽管植入前缺乏听觉语言经验）与视觉语言信息。
Objective:To determine whether congenitally deafened adults achieve improved speech perception when auditory and visual speech information is available after cochlear implantation.Study Design:Repeated-measures single subject analysis of speech perception in visual-alone, auditory-alone, and audiovisual conditions.Setting:Neurotologic private practice and research institute.Subjects:Eight subjects with profound congenital bilateral hearing loss who underwent cochlear implantation as adults (aged 18-55 years) between 1995 and 2002 and had at least 1 year of experience with the implant.Main Outcome Measures:Auditory, visual, and audiovisual speech perception.Results:The median for speech perception scores were as follows: visual-alone, 25.9%(range, 12.7-58.1%); auditory-alone, 5.2%(range, 0-49.4%); and audiovisual, 50.7%(range, 16.5-90.8%). Seven of eight subjects did as well or better in the audiovisual condition than in either auditory-alone or visual-alone conditions alone. Three subjects had audiovisual scores greater than what would be expected from a simple additive effect of the information from the auditory-alone and visual-alone conditions alone, suggesting a superadditive effect of the combination of auditory-alone and visual-alone information. Three subjects had a simple additive effect of speech perception in the audiovisual condition.Conclusion:Some congenitally deafened subjects who undergo implantation as adults have significant gains in speech perception when auditory information from a cochlear implant and visual information by lipreading is available. This study shows that some congenitally deafened adults are able to integrate auditory information provided by the cochlear implant (despite the lack of auditory speech experience before implantation) with visual speech information.
