Is It Unusual for an Original Surgeon to Do a Revision After a Poor Result?

From what you describe I would have little hesitation to trust your neck in the hands of your surgeon again. He has the experience and provides the care you want. Discuss before your revision necklift thoroughly what kind of result you can expect and what limitations you should know about.

Most physicians care very much that you obtain a good result from a procedure they do.  Most times, if less than optimal results occur, it is not a result of poor technique of the doctor but they would still want to help you get the result that both you and they would like to see.  Some may charge a facility fee to cover the costs of the material used and nurses' time and some may not charge depending on the procedure.  You could feel free to see a second opinon first and then return to the original surgeon, but it is very common for patients to undergo secondary procedures for improvement by the original surgeon.
