The effects of grommet insertion on Eustachian tube function

A prospective study on the effect of grommet insertion on the passive Eustachian tube opening pressure was undertaken in children's ears with otitis media with effusion. After an initial immediate improvement following aspiration of the middle ear no further change in Eustachian tube function occurred over 4 subsequent weeks. Grommet insertion probably has no effect on Eustachian tube function.
