Please understand that putting tubes in the ear means you are puncturing the eardrum. You must check up on the risk that the drum may not heal properly, or may have scarring. This can affect hearing later in life.
It must be counterbalanced with the probability that the drum will be ruptured anyway due to the force of the fluid from the middle ear on the inside of the drum, or with the possibility that the infection can spread to other structures. It is not a simple decision. Please get 2nd and 3rd opinions from expert MD’s.
