目的 评估自闭症患儿的听功能和传出神经功能.方法 对30例自闭症患儿和15例正常儿童分别行听性脑干反应(ABR)和耳声发射(OAE)测试,并以55 dB nHL白噪声为对侧抑制声,进行畸变产物耳声发射(DPOAE)和瞬态诱发耳声发射(TEOAE)对侧抑制效应测试,比较两组结果.结果 ①ABR检查结果:30例(60耳)自闭症患儿中,25例(50耳)的ABR阈值均在20 dB nHL以内,1例左耳阈值为30 dB nHL,右耳阈值为40 dBnHL,1例(2耳)阈值均为50 dB nHL,3例(6耳)ABR未引出;正常组15例(30耳)ABR阈值均在20 dB nHL以内;与正常组左、右耳Ⅰ-Ⅴ波间期(分别为4.30±0.14、4.31±0.14 ms)比较,自闭症组(分别为4.07±0.24、4.08±0.22 ms)有缩短的趋势(P＜0.05);②OAE检食结果:正常组均可引出;30例自闭症患儿除3例ABR未引出者和1例双耳ABR阈值为50 dB nHL者OAE未引出外,其余26例均引出,且1、2 kHz OAE幅值与正常组差异有统计学意义(P＜0.05);③对侧抑制结果:正常组幅值均降低;自闭症组26例OAE可引出者中,1例ABR阈值不对称者对侧给予55 dB nHL白噪声后,OAE幅值小降低反而升高,其余25例OAE幅值均降低;两组OAE对侧抑制幅值差值无统计学差异.结论 与同龄正常儿童相比,自闭症患儿更容易出现听功能障碍.
目的 評估自閉癥患兒的聽功能和傳齣神經功能.方法 對30例自閉癥患兒和15例正常兒童分彆行聽性腦榦反應(ABR)和耳聲髮射(OAE)測試,併以55 dB nHL白譟聲為對側抑製聲,進行畸變產物耳聲髮射(DPOAE)和瞬態誘髮耳聲髮射(TEOAE)對側抑製效應測試,比較兩組結果.結果 ①ABR檢查結果:30例(60耳)自閉癥患兒中,25例(50耳)的ABR閾值均在20 dB nHL以內,1例左耳閾值為30 dB nHL,右耳閾值為40 dBnHL,1例(2耳)閾值均為50 dB nHL,3例(6耳)ABR未引齣;正常組15例(30耳)ABR閾值均在20 dB nHL以內;與正常組左、右耳Ⅰ-Ⅴ波間期(分彆為4.30±0.14、4.31±0.14 ms)比較,自閉癥組(分彆為4.07±0.24、4.08±0.22 ms)有縮短的趨勢(P＜0.05);②OAE檢食結果:正常組均可引齣;30例自閉癥患兒除3例ABR未引齣者和1例雙耳ABR閾值為50 dB nHL者OAE未引齣外,其餘26例均引齣,且1、2 kHz OAE幅值與正常組差異有統計學意義(P＜0.05);③對側抑製結果:正常組幅值均降低;自閉癥組26例OAE可引齣者中,1例ABR閾值不對稱者對側給予55 dB nHL白譟聲後,OAE幅值小降低反而升高,其餘25例OAE幅值均降低;兩組OAE對側抑製幅值差值無統計學差異.結論 與同齡正常兒童相比,自閉癥患兒更容易齣現聽功能障礙.

Objective To assess hearing and efferent system functions of autistic children.Methods Tests were performed on 30 Autistic children and 15 normal children to evaluate hearing objectively by using otoacoustic emission (OAE) and auditory brainstem response (ABR).The efferent system functions were analyzed through contralateral suppression in OAE.Results The mean ABR Ⅰ-Ⅴ interpeak latencies (IPLs) in children with Autism were significantly reduced than that in the control group.The amplitudes of OAE at 1 kHz and 2 kHz in autistic children were significantly different in two groups.There were no significant differences in contralateral suppressions between the Autistic children and the control.Conclusion Hearing impairment may be more common in children with Autism than in normal children,while for a few Autistic children,their efferent system functions are affected.
