ABSTRACT

Objective To study the relationship between tubomanometry(TMM) and tympanograms before and after the treatment of otitis media with effusion(OME) in children,and to evaluate the function of tubomanometry in forecasting the prognosis of OME.Methods Data from 66 patients(98 ears) were collected before and after one to four weeks treatment,all the patients received tympanometry and tubomanometry ETS,recorded eustachian tube scores(ETS) and tympanogram types.Results Before treatment,there were significant differences between the ETS of normal ears and sick ears,also between ETS of type B tympanograms and type C.There was significant difference between ETS before and after treatment,but not between the ETS of type B tympanograms and type C after treatment.The increased ETS value of type B tympanograms was higher than type C with a significant difference.There was a significant difference between the ETS of the effective group and the invalid group before and after treatment,whether type B tympanograms or type C.Conclusion Eustachian tube scores increased after treatment,and the functions of eustachian tube were improved in children of otitis media with effusion.Before treatment,the ETS of type B tympanograrns was lower than type C,indicating a poorer function of eustachian tube.After treatment,the increased ETS value of type B tympanograms was more than type C.Tubomanometry could forecast the prognosis of otitis media with effusion in children.
