Ear tube surgery is a very quick procedure, and the side effect is minimal.
My son did it a month ago. No ear infections and no complications so far.
Since his ear pain is gone, he becomes happier and more active.
They put a mask on him to put him to asleep (sedation), and he woke up right
after the 15 min procedure. He resumed normal activities that same
afternoon.
Usually for little kids, doctors don't give them IV anesthesia injection.
Of course, every surgery carries certain risk. You have to weigh the pros
and cons.
