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.
Depending on the specific condition in patientâs ear, an operation on the mastoid bone to control infection may be done, together with a procedure to restore hearing. This procedure is called a tympanomastoidectomy. The mastoid is a honeycomb cavity in the temporal bone, which lies directly behind the ear and is connected to the middle ear space. When a hole arises in the eardrum due to previous injury or infection, or when a long-standing infection persists with tissue in the middle ear or mastoid, mastoid surgery often becomes necessary to alleviate this infection. This part of the procedure is called mastoidectomy. The procedure used to restore or retain hearing is called a tympanoplasty. âTympanumâ refers to the middle ear cavity; âplastyâ means ârepair ofâ; thus âtympanoplasty.â
