Abstract:
Objective To establish the judgment basis of ventilation pipe status by 0 daPa wideband acoustic immittance(WAI-0 daPa),and to assist doctors to determine the status of ventilation tube and determine the timing of extubation.Methods A total of 43 children with 62 ears aged 3-6 years old were tested by 0 daPa broadband acoustic reactance test.The normal middle ear function group were ten children with 20 ears.Children with secreto-ry otitis media more than 12 months after tympanic tube catheterization were divided into 11 cases 19 ears of clear ventilation tube group,and 23 ears in 22 cases of ventilation tube blockage group.A total of 107 frequencies of WAI-0 daPa were obtained.The Kruskal-Wallis H and Nemenyi were used to analyze the influence of ventilation tube status on WAI-0 daPa.Results The WAI-0 daPa at 226-667 Hz was significantly higher in the clear ventila-tion tubegroupthan in the normal middle ear group.The WAI-0 daPa at 226-500 Hz was significantly lower in the blocked ventilation tube group than in the clear ventilation tube group.The WAI-0 daPa at 2 000-3 364 Hz and 6 727 Hz in the normal middle ear function group were significantly higher than those in the blocked ventilation tube group.The WAI-0 daPa in low frequencies was less than 20％,the possibility of blackage of eardrum tube was greater.Conclusion The absorptivity in low frequency region of WAI-0 daPa can be used to determine the status of tympanic catheter ventilation tube and assist doctors to determine the timing of extubation.
