摘要
目的 :利用多频稳态诱发反应 (MFSSR)测试聋儿的残余听力 ,比较该方法与听性脑干反应 (ABR)之间阳性率的差异来说明这种客观测试法所具有的优点。方法 :在睡眠状态下测试了 2 78例聋儿的MFSSR及ABR ,分析了MFSSR不同频率阳性反应出现率及阈值分布范围 ,并与ABR阳性反应出现率进行比较。结果 :左右耳MFSSR在 0 .5kHz、1.0kHz、2 .0kHz和 4 .0kHz的阳性率分别为 33.0 9%、70 .5 0 %、4 4 .96 %、19.4 2 %和33.81%、6 6 .91%、4 1.0 7%、17.6 3% ,而ABR的阳性率为 16 .91%和 17.2 7% ,MFSSR后 3个频率的阳性反应出现率要明显高于ABR。结论 :MFSSR作为一种客观测试方法具有频率特性好、刺激强度高、结果由计算机自动判断等特点 。
Objective:To obtain the residual hearing by using multi-frequency steady-state response test in a group of deaf children and to compare the results with that of ABR.Method:Both sides of ears of 278 deaf children had been tested while they were asleep.Result:Positive incidences of MFSSR at 0.5,1?2,4 kHz are 33.09%, 70.50%, 44.96% , 19.42%(left ears)and 33.81%, 66.91%, 41.07%, 17.63%(right ears)respectively. Except 4 kHz, the ratios at the other three frequencies are significant higher than that of ABR.Conclusion:MFSSR is a promising objective audiometry,this kind of test could provide frequency-specific information for hearing diagnosis.
