目的 测量外中耳正常汉族婴幼儿宽频声导抗的能量反射值,为宽频声导抗的临床应用提供参考.方法 选取耳廓、外耳道及鼓膜形态正常,颞骨CT扫描外中耳及内耳结构无异常,且226 Hz及1 000 Hz鼓室图正常的汉族婴幼儿94例(170耳),年龄3～48个月,中位年龄14个月.根据月龄分为3～6月龄组(32耳)、7～12月龄组(53耳)、13～ 24月龄组(46耳)及25～ 48月龄组(39耳).对各组受试婴幼儿进行宽频声导抗测试,采用SPSS 15.0统计软件:分析不同频率能量反射的基本规律及年龄因素对能量反射的影响.结果 宽频声导抗的能量反射值在低频处较高,随频率增大逐渐下降,在4 000 Hz附近达最小值,之后又不断上升直到8 000 Hz.3～6月龄婴幼儿1 000 Hz以下及6 350 Hz以上频率范围内的能量反射值明显低于其他各月龄组,差异具有统计学意义(P值均＜0.05).6月龄以下组能量反射值低、波动范围大,6月龄以上组能量反射值高、波动范围小.结论 汉族外中耳正常婴幼儿的宽频声导抗能量反射值在不同频率的变化趋势与国内外文献报道基本一致.随着年龄的增长,宽频声导抗的能量反射值会发生变化,出生6个月以后逐渐趋于稳定.
目的 測量外中耳正常漢族嬰幼兒寬頻聲導抗的能量反射值,為寬頻聲導抗的臨床應用提供參攷.方法 選取耳廓、外耳道及鼓膜形態正常,顳骨CT掃描外中耳及內耳結構無異常,且226 Hz及1 000 Hz鼓室圖正常的漢族嬰幼兒94例(170耳),年齡3～48箇月,中位年齡14箇月.根據月齡分為3～6月齡組(32耳)、7～12月齡組(53耳)、13～ 24月齡組(46耳)及25～ 48月齡組(39耳).對各組受試嬰幼兒進行寬頻聲導抗測試,採用SPSS 15.0統計軟件:分析不同頻率能量反射的基本規律及年齡因素對能量反射的影響.結果 寬頻聲導抗的能量反射值在低頻處較高,隨頻率增大逐漸下降,在4 000 Hz附近達最小值,之後又不斷上升直到8 000 Hz.3～6月齡嬰幼兒1 000 Hz以下及6 350 Hz以上頻率範圍內的能量反射值明顯低于其他各月齡組,差異具有統計學意義(P值均＜0.05).6月齡以下組能量反射值低、波動範圍大,6月齡以上組能量反射值高、波動範圍小.結論 漢族外中耳正常嬰幼兒的寬頻聲導抗能量反射值在不同頻率的變化趨勢與國內外文獻報道基本一緻.隨著年齡的增長,寬頻聲導抗的能量反射值會髮生變化,齣生6箇月以後逐漸趨于穩定.

Objective To explore the law of wide band typanometry energy reflectance (WBTER) in Chinese infants of Han nationality with normal outer and middle ears,and to provide the normal values for the clinical application of WBTER.Methods Ninety four infants (170 ears) of Han nationality with normal outer and middle ears evidenced by temporal bone CT,and 226 Hz and 1 000 Hz tympanometry at the ages between three and 48 months (median age:14 months) were selected and divided into four groups:3-6 months(32 ears),7-12 months(53 ears),13-24 months(46 ears) and 25-48 months(39 ears).WBTER was conducted on these infants,and the basic law of energy reflectance under different frequencies,as well as the influence of age on energy reflectance were analyzed using SPSS 15.0.Results The normal value of energy reflectance was higher at low frequency,gradually decreased with the increase of frequency,reached the minimum near 4 000Hz,followed by constantly increased till 8 000Hz.In the scope of frequency below 1 000Hz and above 6 350 Hz,the energy reflectance values of infants in the group of 3-6 months were significantly lower than those of infants in other age groups (P ＜ 0.05).In comparison to the group below six months,the groups over six months generally had higher energy reflectance and lower fluctuation.Conclusions The pattern of energy reflectance across frequency range for Chinese infants and children was consistent with that of other races reported in foreign countries.The WBTER changes with the growing of age,which tends to be stable after the first six months of birth.
