中文摘要：

对于韦伯试验中单侧传导性聋引起骨导听觉偏向患侧这一现象有多种解释,主要包括骨导信号的耳间强度差和相位差2类,但韦伯试验骨导偏向的具体机制仍需进一步研究。本文综述了包括外耳道堵塞、听骨链畸形、耳硬化等各种外中耳异常情况对骨导听觉的影响。外中耳病理和生理异常与传导性聋具有密切关系,在不同程度上都会影响耳间强度差和相位差。

英文摘要：

The phenomenon that bone-conducted sound lateralized to the side of a conductive heating loss （CHL） in Weber test has multiple explanations, mainly including the interaural intensity difference （liD） and interaural phase difference （IPD） of the bone-conducted signal. Nevertheless, further investigations are still required to reveal the mechanism responsible for the lateralization. In this paper, classified abnormalities including the occlusion of the external auditory canal, abnormal ossicular chain and otosclerosis, as well as their influence on bone-conducted hearing, were discussed in detail. Various types of outer and middle ear pathological and physiological abnormalities, which are closely related with CHL, influence IPDs and IIDs.
