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.
Ear Tubes. Recurring ear infections or fluid build-up in the middle ear may require the temporary placement of tubes in the ear. Ear tube surgery involves a very small incision in the eardrum, which is a thin layer of tissue separating the outer and middle ear. The procedure is known as a myringotomy or tympanostomy. A small, plastic tube shaped like a hollow spool (a tympanostomy tube) is then inserted into the eardrum to keep the middle ear drained and ventilated. The tubes remain for 6 months to several years, and eventually fall out or are removed by a doctor.
