“A tympanostomy tube (also known as a grommet or ear 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 mucus in the middle ear. The operation to insert the tube involves a myringotomy. The tube itself is made in a variety of designs. The most commonly used type is shaped like a grommet or T. When it is necessary to keep the middle ear ventilated for a very long period, a “T”-shaped tube may be used. 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.”
“Long term studies have called the necessity of routine ear tube surgery into question.”
