You have posted some insightful questions.
I posted the following in response to a similar thread:
"I do not want to
overwhelm you, so basically I am going to tell you the basics:
Ask as many questions as you can.
Ask them how many surgeries they perform annually, as well as specifically how many surgeries they do monthly and/or annually as well.
Ask to see before and after pics of surgeries they have performed, specifically before and afters that pertain to your specific situation.
Go with your gut ... do you feel comfortable with this surgeon? Does he or she answer your questions in a thorough fashion? Is the surgeon actually able to answer your questions or do you feel like you are getting vague responses and/or brushed off? Does he or she take the time to answer your questions? Does the surgeon seem knowledgable? Is he or she compassionate?
Do your own research if you can. Speak to former patients (do not depend on the surgeon to provide these patients, as often they are not real patients if the doc is offering their info). Does the doc have lawsuits or has had any? How does the surgeon treat patients post op if they need revision? Does the doc provide good care post op (follow up etc.)?
These are the basics ...
