Tympanostomy tubes are small, cylindrical devices inserted into the eardrum to help drain fluid and equalize pressure in the middle ear. They are commonly used in children who experience frequent ear infections or fluid buildup, which can affect hearing and lead to other complications. The procedure to place these tubes is typically quick and performed under anesthesia. Once inserted, tympanostomy tubes allow air to enter the middle ear, reducing the risk of infections and improving hearing. They usually remain in place for several months to a few years before falling out on their own or being removed by a doctor.
