目的初步评价颞叶癫痫患者的听觉功能。方法对19例单侧颞叶癫痫患者(左侧10例,右侧9例),进行500Hz低通滤波言语测试、纯音测听、ABR及声导抗测试。选择20例健康人做对照组。结果纯音测听示实验组中纯音听阈均<25dB,分别与对照组相比,差异无显著意义(P>0.05);ABR检查中实验组与对照组在各波潜伏期、波间期差异无显著意义(P>0.05);实验组500Hz低通滤波言语识别率、“未滤-低通差”分别与对照组相比,差异无显著意义(P>0.05),但左颞叶癫痫患者组“未滤-低通差”右耳(69.7±12.3)%,左耳(67.1±10.3)%大于对照组右耳(61.7±8.3)%,左耳(60.1±8.3)%。结论实验结果未发现颞叶癫痫患者有明显听觉障碍。左颞叶癫痫患者“未滤-低通差”有增大趋势。
Objective To evaluate the auditory function of patients with temporal lobe epilepsy. Methods Twenty-nine patients with unilateral temporal lobe epilepsy (left 10 cases, right 9 cases) underwent 500 Hz low-pass filtered speech test, pure tone audiometry, ABR and acoustic impedance test. Choose 20 healthy people as the control group. Results Pure tone audiometry showed that pure tone threshold was <25dB in the experimental group, there was no significant difference compared with the control group (P> 0.05). There was no significant difference between the experimental group and the control group (P> 0.05). Compared with the control group, the speech recognition rate of the low-pass filter of 500 Hz in the experimental group was no significant difference (P> 0.05) (69.7 ± 12.3)% for the unfiltered - low-pass poor, 67.1 ± 10.3% for the left ear and 61.7 ± 8.3% for the right ear and 60.1 ± 8.3% for the left ear of the control group. Conclusion The experimental results did not find obvious temporal disturbance in patients with temporal lobe epilepsy. Patients with left temporal lobe epilepsy “unfiltered - low-pass” have an increasing trend.
