摘要
目的探讨瞬态诱发耳声发射(transient evoked otoaeoustic emission,TEOAE)应用于中国农村学龄儿童听力筛查的意义和可行性。方法用Madsen Celesta 503耳声发射仪对317例(634耳)正常农村小学1-6年级学生进行听力筛查,并用耳镜、纯音测听和鼓室导抗图系列检查作为“金标准”,验证其结果。结果317例(634耳)儿童TEOAE的通过率为94.64%(600/634),金标准的通过率为94.48%(599/634)。TEOAE测试中,一致百分率为96.69%±0.71%,灵敏度为0.69±0.078(69%±7.8%),特异度为0.98±0.0052(98%±0.52%),漏诊率β=0.31,误诊率α=0.02,Youden指数J=0.67±0.078,阳性似然比LR+=34.5,阴性似然比LR_=0.32,阳性预报值PV+=0.71(71%),阴性预报值PV_=0.98(98.%),AZ=0.8。结论TEOAE测试具有方便、快速、无创、灵敏、客观等优点,是较好的中国农村学龄儿童听力筛查的方法。
Objective To investigate the clinical meaning and feasibility of transient evoked otoaconstic emission (TEOAE) in China rural primary school children hearing screening. Methods TEOAE was recorded with Madsen Celesta 503 in 317 (634 ears) primary school children,then the results were compared with gold standard test group, including otoscopy, pure tone audiometry and tympanogram. Results In 317 (634 ears) pupils, the presence of TEOAE was 94.64% (600/634) ; the presence of gold standard was 94.48 % (599/634). The consistency rate was (96.69 ± 0.71 )%; sensitivity (Sen) was 0.69 ± 0. 078; specificity (Spe) = 0.98 ± 0.0052, the false positive rate (FPR), that was β, was 0.31; α = 0.02; Youden' s index J = 0.67±0.078, LR+ =34.5, LR_ =0.32, PV+ =0.71(71%),PV_ =0.98(98.%),AZ=0.8.Conclusion The TEOAE test is simple, quick, harmless, sensitive and objective. It can be used in hearing screening program in rural primary school children.
