Should you have your upper blepharoplasties done by a senior-level resident (trainee)? On the one hand you obtain the procedure at a greatly reduced cost. Moreover, you contribute to the training experience of a plastic surgery resident. I wish that we had had resident aesthetic clinics in the era when I trained. We did not, and were expected simply to learn aesthetic skills on our own. On the other hand there is virtually no such thing as a 'simple' operation; I have found that I continue to refine even the most straightforward operations some thirty years into my career. If you are seeking the best possible outcome, as one of my colleagues has already stated on this page, there is absolutely no substitute for experience. All the best!
Residents are supervised closely by attending surgeons. The attending surgeons are well respected surgeons with extensive experience. Discuss your concerns with your surgeon. The residents are limited in scheduling and when they can see you because of their schedules.
Without a full set of pictures, it's very difficult to comment on what may be required and how difficult the procedure would be. Experience is very important in elective cosmetic eyelid surgery. It probably best to have a frank discussion with the supervising surgeon about their level of expertise that the resident surgeon can deliver an excellent result
I seriously doubt the money you are going to save is worth subjecting yourself to this. These surgeries are highly technique dependent. If you are simply having functional surgery and do not particularly care about the outcome, then perhaps you will be satisfied with the result. However, cosmetic eyelid surgery is truly fussy and requires very finesse and care. There is no substitute for experience.
