Surgical placement of yo-yos, also known as transtympanic aerators or diabolos, is one of the most common treatments offered when a child has recurrent ear infections.
These drains are very small hollow plastic tubes that are placed through the tympanic membrane to form a small hole in the eardrum. This allows for permanent ventilation of the eardrum and prevents recurrence of ear infections.
It is strongly recommended not to bathe when you have yo-yos because the water could cause inflammation or infection (no water in the ears, no swimming, no drops).
The area to be protected is complex, especially due to the shape of the ear and the small surface area to glue.
