suni, I understand being thoughtful and considerate, but your focus needs to be to find the best solution for you.
Your doctor is there to provide a service for you as a patient and as a customer. He or she can have an ego, but if you reach the decision that you need other input from surgeons who are specialists and are much more experienced, your decision rules this. It is your body and you will suffer any consequences and reap the rewards of your judgement.
If you had a problem with your eyes, no matter how good your general practitioner is, you are referred to en eye doctor because of their experience. The same principle applies here, especially if you have access to some of the best surgeons in this specialty.
So ego or not, he has no reason to be anything but supportive. Having said that, I and others here also had to assert myself and move to another doctor when the service (HR) that I wanted was being argued against by surgeons in very good standing in the Boston area. I had no problem telling them that I was going to another doctor for an opinion.
Too bad if their egos suffered. It is your decision.
