摘　　要：使用NicoletSpirit诱发电位测试系统，结合纳音测听等对76例耳部和头领受伤者113耳进行检测。受试者分为两类：一是鼓膜穿孔32耳，分为小穿孔、中穿孔及大穿孔；二是鼓膜无穿孔81耳，分为轻度聋、中度聋、重度聋、严重聋及极度聋。分别进行耳蜗电图（EcochG）和听性脑干反应（ABR）测试，将鼓膜小穿孔、中穿孔和鼓膜无穿孔的轻度聋、中度聋与正常对照组的相关反应波潜伏期分别进行统计学分析表明，在方差分析和60项双项比较的Q检验中得出有显著差异者（P＜0．05）达76．7％，其中极显著差异者（P＜0．01）达70％。A hundred thirteen ears in 76 cases underwest the traumatic deafness caused by beating at the ear and head were examined with the Evoked Potential System of Nicolet Spirit and the Pure tone audiometry.113 ears were divided into two groups. One group consisted of 32 ears with the tympanal perforation, which were further divided into small, medium and big perforations. The second group consisted of 81 ears without tympanal perforation,which were classified into mild, moderate,serious,severe and profound deafness. The two groups were all examined by EcochG and ABR. The wave latent periods of EcochG and ABR of two groups (small, medium perforation;mild,moderate deafness)were statistically analysed and were compared with those of the normal control group. The results of the square deviation analysis and Q test showed the significant difference (76. 7%, P<0.05; 70%, P<0. 01).
