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.
Background. Myringotomy is a surgical procedure of the eardrum or tympanic membrane. The procedure is performed by making a small incision with a myringotomy knife through the layers of tympanic membrane (see the image below).his surgical procedure permits direct access to the middle ear space and allows the release of middle-ear fluid, which is the end product of otitis media with effusion (OME), whether acute or chronic. OME is classified as serous, mucoid, or purulent. Myringotomy (radial incision).
