【摘要】： 目的探討不同頻率探測音聲導(dǎo)抗測試及多頻率掃描聲導(dǎo)抗測試在診斷嬰幼兒中耳功能中的作用。 方法使用GSI TympstarⅡ中耳分析儀對122例聽力正常嬰幼兒和141例聽力異常嬰幼兒進(jìn)行226Hz、678Hz、1000Hz探測音聲導(dǎo)抗測試及多頻率掃描聲導(dǎo)抗測試并進(jìn)行統(tǒng)計學(xué)分析。 結(jié)果對6月齡的嬰幼兒226Hz探測音鼓室導(dǎo)鈉測試的鼓室圖參數(shù)及圖形變化在聽力正常組和異常組間的差異無統(tǒng)計學(xué)意義,而對6月齡的嬰幼兒其鼓室圖參數(shù)在兩組之間有統(tǒng)計學(xué)意義;各月齡組的678Hz、1000Hz探測音鼓室導(dǎo)鈉圖的圖形特點(diǎn)在聽力正常組和異常組間的差異均有統(tǒng)計學(xué)意義(P0.05);在6月的嬰幼兒聽力正常組和異常組,其兩組之間共振頻率的差異無統(tǒng)計學(xué)意義(P0.05),而在6月齡其差異有統(tǒng)計學(xué)意義(P0.05);在正常組中,嬰幼兒中耳共振頻率隨著月齡的增加而逐漸增加,在11月齡后其中耳共振頻率達(dá)到正常范圍。 結(jié)論3種頻率探測音聲導(dǎo)抗測試對于6月齡的嬰幼兒中耳功能的診斷均較敏感,678Hz、1000Hz探測音聲導(dǎo)抗測試對6月齡嬰兒中耳功能的檢查較準(zhǔn)確。正常嬰幼兒中耳的共振頻率在11月齡后達(dá)到正常范圍,其對6月齡的嬰幼兒中耳功能的檢查有一定的幫助。
[Abstract]:Objective to investigate the effect of different frequency probe audiometry and multi frequency scanning acoustic impedance test in the diagnosis of middle ear function in infants.
Methods using the GSI Tympstar II middle ear analyzer, 122 cases of normal hearing children and 141 cases of hearing abnormal infants were tested with 226Hz, 678Hz, 1000Hz detection sound and multiple frequency scanning acoustic conductance test and were statistically analyzed.
Results there was no significant difference in the variations of the tympanic map parameters and graphic changes between the normal and abnormal groups of the 6 month old infants with 226Hz detection in the sound tympanum test. The parameters of the tympanic map for the 6 month old infants and young children were statistically significant between the two groups. The graphical characteristics of the 678Hz, 1000Hz sounding tympane guided sodium map of each month group There was significant difference between the normal hearing group and the abnormal group (P0.05). There was no significant difference in the resonance frequency between the two groups in the normal hearing group and the abnormal group in June (P0.05), but the difference between the two groups was statistically significant (P0.05); in the normal group, the resonance frequency of the middle ear in the infants was increased with the increase of the age of the month. Gradually increased, after 11 month old, ear resonance frequency reached normal range.
Conclusion 3 kinds of frequency detection sound acoustic conductivity test are sensitive to the diagnosis of middle ear function in 6 month old infants. 678Hz, 1000Hz detection sound acoustic conductivity test is more accurate for the middle ear function of 6 month old infants. The resonance frequency of the middle ear of normal infants reaches the normal range after 11 month old, and the examination of 6 month old of the middle ear function of infants and young children There's some help.
