对20例正常新生儿在出生后第1～5天逐日行瞬态诱发性耳声发射(TEOAE)和畸变产物耳声发射(DPOAE)的测试。了解不同日龄新生儿畸变产物耳声发射(DPOAE)和瞬态诱发性耳声发射(TEOAE)的特征,探讨应用OAE作新生儿听力筛查的最佳时机。随新生儿日龄的增加,其TEOAE和DPOAE检出率和反应幅值逐步提高,新生儿生后第1～2天的检出率和反应幅值显著低于第3～5天,至生后第3～5天,TEOAE和DPOAE检出率接近或达到100％,反应幅值也趋于稳定。结论:应用TEOAE和DPOAE进行新生儿听力筛查时,其日龄至少应在3天或3天以上,测试TEOAE和DPOAE快速、方便,不失为普遍性新生儿听力筛查首选方法。
Ten normal neonates were tested for day-to-day transient evoked otoacoustic emissions (TEOAE) and distortion product otoacoustic emissions (DPOAE) 1 to 5 days after birth. To understand the features of DPOAE and TEOAE in neonates of different ages, and to explore the best time to use OAE for neonatal hearing screening. The detection rate and response amplitude of TEOAE and DPOAE gradually increased with the increase of the newborn’s age. The detection rate and the response amplitude of the first to the second days after neonatal birth were significantly lower than the 3rd to 5th days, After 3 to 5 days, TEOAE and DPOAE detection rate close to or reached 100%, the reaction amplitude tends to be stable. CONCLUSIONS: TEOAE and DPOAE should be used at least for 3 days or more in newborn hearing screening. It is a fast and convenient method to test TEOAE and DPOAE, which is the first choice of neonatal hearing screening.
