Both of my twins had ear tubes placed (in both ears for each!) around 10 months of age. Their surgeries went smoothly and we did not experience any longterm complications from the surgeries. (One aside, one of the reasons we had the tubes placed so early is that one of our twins daughters had been on antibiotics for months on end. She developed an allergy to sulfa drugs subsequently).
None of my children have experienced complications with anesthesia , so I can't help you there! Good luck!
