【摘要】：目的通过比较健听青年颅顶慢反应(slow vertex response,SVR)阈和短纯音听性脑干反应(toneburst auditory brainstem response,tb-ABR)阈与纯音听阈(pure tone audiometry,PTA)的关系,探讨SVR和tbABR用于听阈评估的价值。方法对30例健听青年分别进行双耳0.5、1、2、4kHz频率的tb-ABR、SVR反应阈及PTA测试,比较各频率SVR、tb-ABR反应阈与纯音听阈的差值及其相关性。结果 SVR反应阈与PTA在0.5kHz频率处的差值最小,为3.59±7.32dB,在1、2、4kHz频率的差值分别为6.92±5.07、8.33±6.71、9.83±9.41dB;tb-ABR反应阈与PTA在4kHz频率处的差值最小,为14.58±7.24dB,在0.5、1、2kHz频率处的差值分别为29.42±6.83、23.25±7.47、16.50±6.43dB;各频率SVR和tb-ABR反应阈与PTA差异均有统计学意义(均为P0.05)。SVR与PTA在1、2kHz处有较好相关性(分别为r=0.51,P0.01和r=0.44,P0.05);tbABR与PTA在4kHz处有较好相关性(r=0.53,P0.01)。结论在听力正常的青年人群中,SVR和tb-ABR反应阈均能较好地预估PTA,前者更接近PTA。
[Abstract]:Objective to explore the value of SVR and tbABR in the evaluation of auditory threshold by comparing the relationship between (slow vertex response,SVR threshold and (toneburst auditory brainstem response,tb-ABR threshold and pure tone threshold (pure tone audiometry,PTA. Methods the tb-ABR,SVR response threshold and PTA were measured at the frequency of 0.5kHz and 2kHz in 30 healthy young people. The difference between SVR,tb-ABR response threshold and pure tone hearing threshold at each frequency and its correlation were compared. Results the difference between SVR reaction threshold and PTA at 0.5kHz frequency was the smallest (3.59 卤7.32 dB), and the difference between PTA and PTA at 4kHz frequency was 6.92 卤5.07 卤6.71 卤9.83 卤9.41 dBtb-ABR, respectively. The difference was 29.42 卤6.83 卤7.47 卤16.50 卤6.43 dB at the frequency of 0.5 卤7.24 dB, respectively, and there was significant difference between the response thresholds of SVR and tb-ABR in each frequency (P0.05). There was a good correlation between PTA and PTA at 12 kHz (r0.51kHz, P0.01 and RP0.44P0.05), and there was a good correlation between PTA and PTA at 4kHz (r0.53P0.01). Conclusion both SVR and tb-ABR threshold can predict that PTA, is closer to PTA. in young people with normal hearing.
