Ear tubes, also known as tympanostomy tubes, ventilation tubes, myringotomy tubes, or pressure equalization tubes, are tiny, hollow cylinders made of plastic or metal that are surgically placed into the eardrums. They are commonly used in children or adults who have chronic middle ear infections or infections that have resisted treatment. The purpose of ear tubes is to provide ventilation to the middle ear, prevent fluid buildup, and allow air to flow in and out, which helps to drain fluid that builds up behind the eardrum. They are inserted to equalize air pressure between the middle ear and the outside and to help drain fluid that builds up behind the eardrum. Ear tubes can help prevent ear infections by allowing air into the middle ear, and while they wont prevent all ear infections, they can make them milder and happen less often. Most ear tubes are designed to fall out on their own in 6 to 18 months, and the holes heal on their own. In some cases, the tubes might need to be put in again, but in most cases, surgery to remove an ear tube isnt necessary as the tube usually falls out on its own as the eardrum heals.
