The tympanostomy tube also called a pressure equalization tube is known in common parlance by the terms grommet or vent. This is a device placed through the eardrum, which connects the middle ear with the external ear. The tympanostomy tube is recommended in cases of too frequent ear infections and can evacuate the liquid generated during recurrent ear infections. This prevents deafness, the unfortunate result of repeated ear infections. The installation of the tympanostomy tube is done in surgery under general anesthesia, this operation is called paracentesis.
