How do doctors remove ear tubes? is it a surgical procedure?

Ear tubes: Ear tubes are quite often expelled spontaneously after the problem is solved ie if placed for increased pressure or persistent pus in the muddle ear, they are expelled when the problem is cleared and stays cleared ie pressure is relieved or pus is all discharged. Sometimes the tubes are removed if they are causing trouble or are not needed any more. This is done by the ENT surgeon.

Anesthesia/yes: Tubes are generally left alone and self jettison after 6m to 2yr. If there is a reason to remove them, the kid must be perfectly still (anesthesia) and the tube is removed under direct observation by the ENT using various instruments.
