The tube usually falls out on its own, pushed out as the eardrum heals. A tube generally stays in the ear anywhere from 6 months to 18 months, depending on the type of tube used. If the tube stays in the eardrum beyond 2 to 3 years, though, your doctor might choose to remove it surgically.
Myringotomy is a surgical procedure of the eardrum or tympanic membrane. The procedure is performed by making a small incision with a myringotomy knife through the layers of tympanic membrane.
Myringotomy is a common outpatient surgical procedure. It can be performed under general inhaled anesthesia, but it is usually carried out under local anesthesia by lidocaine infiltration or instillation of different anesthetic agents.
Myringotomy is associated with a very quick recovery period. Most patients experience minimal pain and discomfort, and some may require antibiotic ear drops after surgery. Once tympanostomy tubes are placed, you will no longer be able to scuba dive or swim deeply underwater.
Your child may have a small amount of blood-tinged drainage from the ear for 1-2 days after the operation. If the drainage persists, there could be an infection.
