In this study a comprehensive audiometry was applied to detect the hearing loss in 400 patients (531 ears) with difficult-to-test hearing loss induced by ear or skull injury. It was found that the real PTA detectable rate reached 95.29% and the incidence of hearing loss was 82.11%, of which 68.81% were related to injury. The incidence of nonorganic deafness was 77.59%, i.e., the incidence of hearing loss exaggerated by patients was 57.25% (tested ears), simulated deafness was 16.20% and functional deafness was 4.14%. The principle of dealing with nonorganic deafness was discussed.
本研究采用全面的听力测定法，对400例（531耳）因耳部或颅骨损伤导致听力测试困难的听力损失患者进行检测。结果发现，实际纯音听阈（PTA）可检测率达到95.29%，听力损失发生率为82.11%，其中68.81%与损伤有关。非器质性聋的发生率为77.59%，即患者夸大听力损失的发生率为57.25%（受试耳），伪聋为16.20%，功能性聋为4.14%。并对非器质性聋的处理原则进行了讨论。
