摘要： ［摘要］目的：研究骨导听性脑干反应(ABR)的波形特点及正常的气、骨导ABR Ⅴ波潜伏期-强度曲线及相应的反应阈值，为临床气导ABR（ACABR）和骨导ABR(BCABR)的联合应用提供参考依据。方法：利用Nicoletspirit型诱发电位仪、EAR3A插入式耳机和Radioear B71骨振动器对一组听力正常年轻人（男32耳、女24耳）进行短声气骨导ABR测试，并观察对侧给予白噪声掩蔽对BCABR阈值及潜伏期的影响。结果：气骨导ABR相应强度下波形相似波Ⅴ潜伏期－强度曲线表明，随着刺激强度逐渐减低，潜伏期逐渐延长。骨导Click的潜伏期要比气导Click潜伏期延长的程度大，BCABR反应阈比气导ABR高。对侧70?dBSPL以下强度宽带噪声的使用对BCABR阈值及阈上10?dB强度下波Ⅴ潜伏期均无显著影响（P＞0.05）。结论：(1) BCABR波形特点与相应刺激强度的ACABR极为相似。BCABR与ACABR潜伏期-强度函数曲线可望联合用于传导障碍及其程度的评估；(2) 骨导行为的听阈水平超过40?dBHL时，BCABR难以引出，对其结果的解释应持慎重态度；(3) 骨导ABR测试时常规加对侧噪声掩蔽，但掩蔽声强度不应超过60?dB。

Abstract: ［ABSTRACT］Objective： To observe normative auditory brainstem response (ABR) latencyintensity functions and the threshold and provide reference for combined clinical use of air and boneconducted ABR. Methods: ABR absolute thresholds and latencies(Ⅴwaves)were obtained from 56 ears of 28 young persons with normal hearing using both the EARTONE insert earphone and the Radioear B71 bone viboratory. Results: The air and boneconducted waveⅤlatencyintensity functions exhibited increased latencies as intensity decreased. The boneconducted clicks yielded somewhat longer latencies than the airconducted ones. Conclusions: (1) The waves of air and boneconducted ABR are similar, and more information on ascertaining the presence and magnitude of a conductive hearing loss can be obtained when both air and boneconducted ABR wave V latencyintensity functions are administered. (2) When the threshold of boneconducted hearing exceeds approximately to 40 dBHL, no BCABR responses can be observed. (3) Masking is often necessary when administering boneconducted ABR test, but intensity of masking should not exceed to over 60 dBSPL.
