【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("f28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(P0.05)。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(P0.05)。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。
[Abstract]:Objective to analyze the results of detecting acoustic conductance at 226Hz and 1000 Hz in infants aged 0-36 months. To explore how to select 226Hz and / or 1000 Hz acoustic impedance detection method in clinical practice, 1645 infants (3290 ears) aged 0-36 months were divided into two groups according to hearing evaluation results: 938 cases (1876 ears) in normal hearing group and 707 cases in abnormal hearing group. (1414 ears), divided into seven groups according to their age: group 1: 54 newborns ("f28 days)" (108 ears), including 34 cases (68 ears) of normal hearing group, 355 cases (710 ears) of 3 months of age of 3 months of 2 months of age in the second group, 149 cases of normal hearing group (298 ears), and 537 cases of group 3: 56 months of age. (1074 ears), including 201 cases in the normal hearing group (402 ears), 236 cases (472 ears) in the fourth group at the age of 7 to 9 months, including 143 cases in the normal hearing group (286 ears), 97 cases in the fifth group (n = 97) in 10 months old, including 62 cases (124 ears) in the normal hearing group, and 259 cases in the sixth group (n = 259) in the sixth group at the age of 1324 months (518 ears). There were 249 cases (498 ears) in normal hearing group and 107 cases (214 ears) in the seventh group at 36 months old, including 100 cases (200 ears) in normal hearing group. Results in the normal group, there were positive peaks in 226Hz and 1000 Hz acoustic conductance maps of the tympanic chamber, and most of them were in the broad single-peak type, and a few in the bimodal type. There were 1403 ears (74.79%) with 226Hz single peak, 290 ears (15.46%) with double peak, 1407 ears (64.07%) with 1000 Hz single peak, and 175 ears (5.17%) with double peak. From the first to the fifth month, the normal and abnormal results of 1000 Hz and 226 Hz detection acoustic impedance were statistically significant (P0.05). The consistent rate of 1000Hz group (97.06%) was higher than that of 226Hz group (66.92.78%). The concordance rate of 226Hz group (95.16%) was higher than that of 1000Hz group (58.87%). The normal and abnormal results of detecting acoustic impedance at 1000Hz and 226Hz were statistically significant between the sixth and seventh month groups (P0.05). Conclusion the measurement of acoustic conductance of 226Hz detecting tympanic chamber can not accurately reflect the middle ear function of infants of 10 months old. It is better to evaluate the middle ear function of infants of 10 months of age and detect the acoustic conductance of tympanic chamber at 226 Hz. The test can objectively reflect the middle ear function of 1136 months old infants.
