摘 要:目的分析0-36个月婴幼儿226 Hz和1000 Hz探测音声导抗结果,探讨在临床上如何选择226 Hz和/或1000 Hz探测音声导抗方法将1645例(共3290耳)0-36个月婴幼儿按听力评估结果分为两个大组:听力正常组938例(1876耳)和听力异常组707例(1414耳),按月龄分为七个小组:第一组:新生儿(≦28天)54例(108耳),其中听力正常组34例(68耳);第二组:2~3月龄355例(710耳),其中听力正常组149例(298耳);第三组:4~6月龄537例(1074耳),其中听力正常组201例(402耳);第四组:7~9月龄236例(472耳),其中听力正常组143例(286耳);第五组:10~12月龄97例(194耳),其中听力正常组62例(124耳);第六组:13~24月龄259例(518耳),其中听力正常组249例(498耳);第七组:25~36月龄107例(214耳),其中听力正常组100例(200耳)。结果正常组226 Hz和1000 Hz探测音鼓室声导抗图均存在正峰,并且均以宽大的单峰型最多见,少数为双峰型.其中226 Hz单峰1403耳(74.79%),双峰290耳(15.46%);1000 Hz单峰1407耳(64.07%),双峰175耳(5.17%).第一至第五月龄组组间1000Hz与226Hz探测音声导抗正常和异常结果均有统计学意义(P<0.05)。其中第一至第四月龄组1000Hz组一致率(97.06%,91.95%,91.04%,81.82%)均高于226Hz组(38.24%,68.46%,66.92%,66.78%),第五月龄组226Hz组的一致率(95.16%)高于1000Hz组(58.87%)。第六至第七月龄组组间1000Hz与226Hz探测音声导抗正常和异常结果均有统计学意义(P<0.05)。结论单纯226 Hz探测音鼓室声导抗测试不能准确反映O^10月龄婴幼儿的中耳功能,1000 Hz探测音声导抗测试能更好的评估O^10月龄婴幼儿的中耳功能;;226 Hz探测音鼓室声导抗测试能客观反映11~36月龄婴幼儿的中耳功能。Objective To report results of tympanometry at 1000 Hz or 226 Hz in 1645 infants (0-36months). Methods Based on their hearing evaluation results, 1645 infants were divided into a normal hearing group (n=938, 1876 ears) and an ab-normal hearing group (n=938, 1414 ears). Within each group, cases were further divided into seven age groups, i.e. Group 1 (≦28days of age, n=54 [108 ears] with 34 [68 ears] in normal hearing group), Group 2 (2 to 3 months of age, n=355 [710ears] with 149 [298 ears] in normal hearing group), Group 3 (4 to 6 months of age, n=537 [1074 ears] with 201 [402 ears] in normal hear-ing group), Group 4 (7 to 9 months of age, n=236 [472 ears] with 143 [286 ears] in normal hearing group, Group 5 (10 to 12 months of age, n=97 [194 ears] with 62 [124 ears] in normal hearing group), Group 6 (13 to 24 months of age, n=259 [518 ears] with 249 [498 ears] in normal hearing group) and Group 7 (25 to 36 months of age, n=107 [214 ears] with 100 [200 ears] in nor-mal hearing group). Results Most cases in the normal hearing group showed single broad peak tympanograms with either 226 Hz or 1000 Hz probe tone. A small number of cases in the normal hearing group showed W-shaped tympangrams. With the 226 Hz probe gone, single peaked tympanograms occurred in 1403 ears (74.79%) while W-shaped tympanograms occurred in 290 ears (15.46%). With the 1000 Hz probe tone, single peaked tympanograms were seen in 1407 ears (64.07%) while W-shaped tympanograms were seen in 175 ears (5.17%). The rates of normal and abnormal results were different among groups 1 to 5 (P&lt;0.05). Using the 1000 Hz probe tone, the rate of consistent results in groups 1 to 4 (97.06%, 91.95%, 91.04%and 81.82%re-spectively) were higher than using the 226 Hz probe tone (38.24%, 68.46%, 66.92%and 66.78%, respectively). The rate of con-sistent results in group 5 when using the 226 Hz probe tone (95.16%) was higher than when using the 1000 Hz probe tone (58.87%). In groups 6 an
