A tympanostomy tube (also known as a grommet, T-tube, ear tube, pressure equalization tube, vent, PE tube or myringotomy tube) is a small tube inserted into the eardrum in order to keep the middle ear aerated for a prolonged period of time, and to prevent the accumulation of fluid in the middle ear.hen it is necessary to keep the middle ear ventilated for a very long period, a T-shaped tube may be used, as these T-tubes can stay in place for 2-4 years. Materials used to construct the tube are most often plastics such as silicone or Teflon. Stainless steel tubes exist, but are no longer in frequent use.
Also found in: Wikipedia. tympanometry. indirect measurement of the compliance (mobility) and impedance of the tympanic membrane and ossicles of the middle ear; it is done by subjecting the external acoustic meatus to positive, normal, and negative air pressure and monitoring the resultant sound energy flow.
