Clinical research on consistency of different evaluation methods for eustachian tube function and surgery exploration / 局解手术学杂志

ABSTRACT

Objective To compare the consistency of temporal bone HRCT,tympanium drip method,impedance audiometry for eustachian tube function and exploratory surgery,and to determine the best method for evaluation of eustachian tube function.Methods The examination of the eustachian tube function were given on 68 cases of otitis media with the surgical indication by these three methods above-mentioned in turn.And then compare the evaluation results with the exploratory surgery.Results The count data matching test of temporal bone HRCT,tympanium drip method and impedance audiometry compare with surgery exploration results were κ =0.625,κ =0.472,κ =0.912,respectively,which were in general degree(κ≥0.4).It suggested that the three methods were reliable for evaluation of eustachian tube function.Conclusion Among these three methods,impedance audiometry is the most accurate one,and then temporal bone functional HRCT,the last one is tympanium drip,therefore,the method of impedance audiometry is promoted to evaluate the function of eustachian tube.
