The role of Eustachian tube function in the results of tympanoplasty.
While the Eustachian tube constitutes by its functions of equipression, ventilation and drainage one of the determining elements of sound transmission, it is too the one on which it is the most difficult to take effect. Eustachian tube dysfunctions' persistence after tympanoplasty interfere, by negative pressure in the tympanic cavity, with the good quality of the results as anatomical as functional. Valuation of the tubal function, its keeping and its restoration, before, per- and after operation, must constitute for the otologist a permanent objective.
