2、; Pijl, 1991; Green et al., 1992; van Hoesel et al.,1993). 聽覺中樞可以處理和整合雙側(cè)不同設(shè)備傳來的信號。- 1996年，德國維爾茨堡ENT首次為重建雙側(cè)聽覺，給成人植入雙側(cè)耳蝸。- 1998年，上述機構(gòu)基于同樣目的，給兒童植入雙側(cè)耳蝸。二、雙側(cè)人工耳蝸植入國內(nèi)外現(xiàn)狀二、雙側(cè)人工耳蝸植入國內(nèi)外現(xiàn)狀國際：截止2007年12月，全球雙側(cè)人工耳蝸植入數(shù)量8000，占當時總植入數(shù)量的5%。具估計目前全球人工耳蝸植入數(shù)量350,000例，雙側(cè)植入數(shù)量已超過10000。截止2007年12月，雙側(cè)植入者中，兒童所占比例62%，成人38%。72%的雙側(cè)

3、植入為分期植入，28%為同期植入。同期植入的患者中，58%小于3歲。雙側(cè)植入的小齡化趨勢：以美國為例，2007年前，50%的雙側(cè)植入者為3-10歲，2007年后，雙側(cè)植入小齡化趨勢更明顯，3歲以下兒童比例越來越大。二、雙側(cè)人工耳蝸植入國內(nèi)外現(xiàn)狀二、雙側(cè)人工耳蝸植入國內(nèi)外現(xiàn)狀國內(nèi)：截止目前，國內(nèi)雙側(cè)人工耳蝸植入約300例，僅占總數(shù)1%左右，雙側(cè)植入者中98%為兒童 。近兩年增長趨勢明顯。- 言語識別- 聲源定位- 音樂欣賞- 綜合素質(zhì)三、雙側(cè)人工耳蝸植入效果數(shù)據(jù)三、雙側(cè)人工耳蝸植入效果數(shù)據(jù)言語識別提升：安靜環(huán)境下（兒童）言語識別提升：安靜環(huán)境下（兒童）安靜環(huán)境下雙側(cè)耳蝸的言語識別率提高15%。K
