[Examination of eustachian tube function in chronic suppurative otitis media].

Discussing something about the methods of examining the eustachian tube function of chronic suppurative otitis media. The examination of the eustachian tube function were given on 96 cases of chronic suppurative otitis media with Valsalva method, tympanium drip and acoustic impedance method. Though the former two methods were imperfect, the combination of them was similar to the acoustic impedance method in outcome, which is easy and convenient and doesn't need expensive instrument. The combination of the former two methods in result could get rid of the imperfection of each of them and could evaluate the eustachian tube function in accuracy, which is fit for basic-level hospital.
