Description

technical field

[0001] The technical field of the present invention belongs to measuring instruments in the diagnosis of various parts of organs, in particular to a device for measuring the function of the Eustachian tube, and also to a method for measuring the function of the Eustachian tube. Background technique

[0002] Eustachian tube function detection methods include acoustic impedance audiometry, acoustic measurement, air pressure balance test, pressurized response test and so on.

[0003] At present, acoustic measurement is a relatively physiological detection method, which can measure the active opening function of the Eustachian tube, the opening time of the Eustachian tube during swallowing, determine the abnormality of the Eustachian tube, and objectively record palatal myoclonus and other sensory tinnitus. This method is a reliable method for recording the opening of the Eustachian tube. The positive rate of normal people is 74%-88.2%. The Japanese improved the ...
