Transiently evoked (TEOAEs) and distortion-product otoacoustic emissions at the 2f1-f2 frequency (DPOAEs) are being used as a clinical tool for diagnosis of peripheral auditory pathology. Because both tests are fast and non-invasive, they may be an excellent method for hearing screening in infants and children. The purpose of this study was to compare the TEOAE and DPOAE measures obtained in a group of healthy children.
Sixty-six school-aged children with normal hearing were included in the study. Subjects with recent otologic disease or abnormal tympanograms were excluded. TEOAEs and DPOAEs were performed using a DP Echoport ILO 292 Otodynamics analyzer connected to a portable personal computer. Correlation between TEOAE amplitudes and DPOAE levels was estimated.
Correlation between TEOAE amplitudes and DPOAE levels was highly significant across all measured frequencies. Correlation was more significant at the middle frequencies than at the low and high frequencies.
Although frequency specific information may be obtained by both tests, most reliable results were obtained at the middle frequencies. TEOAE values were more prominent at low frequencies, whereas DPOAEs were more effective at high frequencies. Both methods are reliable, objective, fast and useful tests of the cochlear status and should be included in the standard audiological diagnostic work-up of children.
瞬态诱发耳声发射（TEOAEs）和2f1-f2频率的畸变产物耳声发射（DPOAEs）正被用作诊断外周听觉病理学的临床工具。由于这两种测试都快速且无创，它们可能是婴幼儿听力筛查的极佳方法。本研究的目的是比较一组健康儿童的TEOAE和DPOAE测量结果。
66名听力正常的学龄儿童纳入本研究。排除近期患有耳科疾病或鼓室图异常的受试者。使用连接到便携式个人计算机的DP Echoport ILO 292耳动力学分析仪进行TEOAE和DPOAE测试。评估TEOAE幅度与DPOAE水平之间的相关性。
在所有测量频率上，TEOAE幅度与DPOAE水平之间的相关性非常显著。中频的相关性比低频和高频更显著。
虽然两种测试都可以获得频率特异性信息，但在中频获得的结果最可靠。TEOAE值在低频更突出，而DPOAEs在高频更有效。这两种方法都是检测耳蜗状态的可靠、客观、快速且有用的测试，应纳入儿童标准听力学诊断检查中。
