3、植入为分期植入，28%为同期植入。同期植入的患者中，58%小于3岁。双侧植入的小龄化趋势：以美国为例，2007年前，50%的双侧植入者为3-10岁，2007年后，双侧植入小龄化趋势更明显，3岁以下儿童比例越来越大。二、双侧人工耳蜗植入国内外现状二、双侧人工耳蜗植入国内外现状国内：截止目前，国内双侧人工耳蜗植入约300例，仅占总数1%左右，双侧植入者中98%为儿童 。近两年增长趋势明显。- 言语识别- 声源定位- 音乐欣赏- 综合素质三、双侧人工耳蜗植入效果数据三、双侧人工耳蜗植入效果数据言语识别提升：安静环境下（儿童）言语识别提升：安静环境下（儿童）安静环境下双侧耳蜗的言语识别率提高15%。K
