摘　　要：目的：探讨后循环短暂缺血性发作（PCTIA）患者的听功能状态。方法：选择PCTIA患者62例（124耳）作为PCTIA组，并选择健康成年人30例（60耳）作为对照组。均行纯音测听、声导抗、听觉脑干诱发电位和瞬态诱发耳声发射（TEOAE）检查。应用SPSS14．0统计学软件包进行统计学分析。结果：①PCTIA组与对照组比较，125～8000Hz各频率气导听阈无统计学意义（P〉0．05）；②PCTIA组的TEOAE通过率（42．7％）与对照组比较差异有统计学意义（P〈O．01）；③PCTIA组与对照组比较，I、Ⅲ、V各波潜伏期及I～Ⅲ、Ⅲ～V、I～V波间期都有延长，差异有统计学意义（P〈0．01）。结论：后循环缺血既可以影响耳蜗的血液供应，导致常规听力学检测难以证实的耳蜗功能损害，又可以因缺血缺氧导致听觉脑干功能的损害。耳声发射和脑干诱发电位为PCTIA的诊断及定位提供了帮助。Objective：To study the hearing characteristics in patient with posterior circulation transient ischemic attack（PCTIA）. Method：Sixty-two patients diagnosed by neurologist were selected as experimental group for testing of pure tone audiometry, tympanometry, otoacoustic emissions （OAE） and auditory brainstem response （ABR）. Thirty healthy subjects were chosen as control group. The data were compared between the PCTIA groups and the control group using the SPSS 14.0 software. Resuit：①The difference in pure tone threshold across 125 to 8 000 Hz between the PCTIA group and the control group was not statistically significant （P〉0.05）;②In PCTIA patients, the prevalence of TEOAE was only 42.7% ,significantly different from the control group;③The patients had longer ABR latency and wave interval than the normal controls （P〈0.0]）. Conclusion： Brain-stem and cochlear damage can occur in patients with PCTIA. These results suggest that OAE and ABR be used as im- portant diagnostic test for patients with PCTIA, and might be helpful in localizing abnormality in PCTIA.
