目的 研究先天性外耳道闭锁小儿气导和骨导短声诱发的听性脑干反应(auditory brain stem response,ABR)的特点,评价骨导ABR的应用价值.方法 将受试者分为两组.组1(闭锁组)为16例(21耳)先天性外耳道闭锁患者,年龄在1～13岁之间,平均为5.62岁;组2(对照组)为正常听力小儿15例(25耳),年龄在1～13岁之间,平均为6.1岁.比较两组气、骨导ABR的特点.结果闭锁组气、骨导ABR反应阈值分别为(73.81±7.4)dB nHL和(6.19±4.98)dB nHL,正常组分别为(23.20±4.76)dB nHL和(5.60±5.07)dB nHL.30 dB nHL刺激强度下闭锁组骨导ABR潜伏期与对照组相比差异无显著性.闭锁组气、骨导ABR阈值差值与正常组相比差异有显著性.结论 骨导ABR可以用于评估先天性外耳道闭锁患者的耳蜗功能.
目的 研究先天性外耳道閉鎖小兒氣導和骨導短聲誘髮的聽性腦榦反應(auditory brain stem response,ABR)的特點,評價骨導ABR的應用價值.方法 將受試者分為兩組.組1(閉鎖組)為16例(21耳)先天性外耳道閉鎖患者,年齡在1～13歲之間,平均為5.62歲;組2(對照組)為正常聽力小兒15例(25耳),年齡在1～13歲之間,平均為6.1歲.比較兩組氣、骨導ABR的特點.結果閉鎖組氣、骨導ABR反應閾值分彆為(73.81±7.4)dB nHL和(6.19±4.98)dB nHL,正常組分彆為(23.20±4.76)dB nHL和(5.60±5.07)dB nHL.30 dB nHL刺激彊度下閉鎖組骨導ABR潛伏期與對照組相比差異無顯著性.閉鎖組氣、骨導ABR閾值差值與正常組相比差異有顯著性.結論 骨導ABR可以用于評估先天性外耳道閉鎖患者的耳蝸功能.

Objective To characterize air- and bone-conduction click-evoked auditory brain stem responses (ABRs) in children with congenital external auditory canal atresia and assess the valua of bone conduction ABRs in the clinic. Methods Air- and bone-conduction click-evoked ABRs in 16 children with congenital malformations of the external ear (aged l-13years) were compared to those in 15 age-matched normal-hearing children. Results ABR threshold was 73.81 ± 7.4 dB nHL for air conduction and 6.19 ± 4.98 dB nHL for bone conduction in children with external auditory canal malformation;and 23.20 ± 4.76 dB nHL and 5.60 ± 5.07 dB nHL respectively in normal hearing children. While the air-bone ABR threshold gap was greater in children with ear canal atresia than in normal hearing children, bone-conduction ABR wave V latency was not statistically different between the two groups. Conclusion Bone conduction ABR is valuable in assessing cochlear reserve in individuals with congenital atresia of the external auditory canal
