Abstract:
Objective The aim of the study was to analyse the middle ear function of one hundred and twenty-five newborns using 226,678,1 000 Hz tympanometry. Methods Tympanometries with 226,678,1 000 Hz probe tones were obtained from 125 newborns (250 ears) by means of GSI Tympstar middle ear analyzer. The newborns with abnormal tympanograms were referred for temporale CT. Results One case of 226 Hz tympanograms was type "As" while others were all type "A",of which single-peaked tympanograms was 43.2%(108/250),W-shaped tympanograms was 56.8%(142/250). The abnormal pattern of 678 Hz tympanograms were 74 ears,and the abnormal pattern of 1 000 Hz tympanograms were 35 ears. 43 newborns (86 ears) have accepted temporale CT and results showed 30 middle ears with effusion. Conclusion 226 Hz probe tone tympanometry couldn't reflect the middle ear function of newborns. The sensitivity of 678 Hz probe tone tympanometry in the diagnosis of middle ear function of newborns was good,but specificity was worse. The sensitivity and specificity of 1 000 Hz probe tone tympanometry were the best.
