Abstract:
OBJECTIVE:To study the characteristics of infants middle ear function of children (0-1 year old) with 226 Hz, 1000 Hz tympanometry.
METHOD:Tympanometric data using 226 Hz, 1 000 Hz probe tones were gained from 150 children (300 ears) aged 0-1 year old with a GSI tympstar middle ear analyzer. All of them were term birth, divided into 5 groups of 30 patients, the neonatal period (0-28 days), 6 weeks (+/- 3 days), 3 months (+/- 6 d), 6 months (+/- 6 days), 7-12 months. To analyse the middle ear function of children with 226 Hz, 1000 Hz tympanometric data.
RESULT:226 Hz,1000 Hz probe tone tympanometric data were normal for the normal group, which respectively were: 76.7%, 80%, 86.7%, 90%, 93.3%. 226 Hz, 1000 Hz detection tympanometric data were not sound normal to abnormal group, the proportion in each group were: 13.3%, 8.3%, 5.0%, 3.3%, 1.6%. The contradiction between the two groups were divided into two subgroups: 226 Hz normal, 1000 Hz unusual in the proportion of each group were 6.7%, 6.7%, 5.0%, 3.3%, 1.6%; 1000 Hz normal, 226 Hz unusual in the proportion of each group were 5.0%, 5.0%, 3.3%, 3.3%, 3.3%.
CONCLUSION:The sensitivity and specificity of the 1000 Hz probe tone tympanometry was better.
