摘　　要：目的:探讨正常新生儿多频探测音鼓室声导抗图的图型、声导纳值、声纳值和声导值的正常范围。方法:使用GSI-33中耳分析仪,对足月顺产并通过瞬态诱发性耳声发射和畸变产物耳声发射筛查的新生儿55例(110耳)进行226、6781、000 Hz探测音鼓室声导抗测试,对比分析各种探测音鼓室声导抗的图形,声导纳值、声纳值和声导值,并进行统计学分析。结果:226 Hz探测音鼓室声导纳图、声纳图和声导图以双峰型为主,分别占90.0%、99.1%和85.5%,少数为单峰型,无多峰型出现;678 Hz探测音鼓室声导纳图、声纳图和声导图以单峰型为主,分别占62.7%、77.3%和62.7%,双峰型分别占34.6%、20.9%和31.8%,少数出现三峰型;1 000 Hz探测音鼓室声导纳图、声纳图和声导图以单峰型为主,分别占96.4%、99.1%和97.3%,极少数为双峰型,无三峰型出现。226 Hz与678 Hz探测音测试,鼓室声导纳值与声纳值、声纳值与声导值的均差异有统计学意义(均P<0.05);声导纳值与声导值差异无统计学意义(P>0.05)。1 000 Hz探测音测试,鼓室声导纳值、声纳值与声导值的两两比较均差异有统计学意义(均P<0.05)。结论:获得正常新生儿多频探测音鼓室声导抗图的图形、声导纳值、声纳值和声导值的正常范围,结果提示,1 000 Hz探测音鼓室声导抗测试可以较好反映正常新生儿的中耳功能。Objective：To discuss the multiple-frequency probe tones tympanograms and the normal ranges of admittance ,susceptance and conductance in normal newborns. Method：Tympanometries with 226 Hz, 678 Hz and 1 000 Hz probe tones were obtained from newborn infants with normal TEOAE and DPOAE（55 infants, 110 ears）, analysed multiplefrequency prone tones tympanograms and values of admittance, susceptance and conductance by using GSI-33 middle ear analyzer. Result：226 Hz tympanograms for admittance,susceptance and conductance main were W-shaped, the percentages were 90.0% ,99.1% and 85.5 %. 678 Hz tympanograms for admittance,susceptance and conductance main were single-peaked, the percentages of single-peaked type were 62.7%, 77.3 % and 62.7% ,and the percentages of W-shaped type were 34.6%, 20.9 % and 31.8%, had a little three-peaked type. 1 000 Hz tympanograms for admittance , susceptance and conductance main were single-peaked, and percentages were 96, 4%,99.1% and 97.3%,and had a little W-shape type but no three-peaked type, There were significant differences between admittance and susceptance,susceptance and conductance in 226 Hz and 678 Hz probe tones tympanogram. There were significant differences between admittance and susceptance, susceptance and conductance, admittance and conductance in 1 000 Hz probe tones tympanogram. Conclusion.. Multiple-frequency probe tones tympanograms and the normal ranges of admittance , susceptance and conductance of normal newborn infants is obtained, and 1000 Hz probe tone tympanometry is a sensitive test for function of middle ear in newborn infants.
