As in any case where a procedure is reccomended a second opinion is a must.
As far as the experience, one of my children has had tubes inserted more then once. Tubes generally fall out after a year and my child’s eustachean (sp?) tubes had not developed enough after the first set of tubes to allow the fluid to drain quick enough. The concern is that hearing damage can result.
The procedure itself was very quick, there was about an hour after the procedure were we waited for anesthesia to wear off. My child did not seem to suffer any significant discomfort.
There are tubes that are designed to remain in for longer then a year and would have to be removed rather then fall out.
Regular follow up with the ENT is necessary to make sure they are effective.
