Katie, I find myself so angry that you have chosen to put yourself in this situation (live in Canada, have surgery in Mexico, and ask trained, experienced plastic surgeons in the US and Canada who are donating their time to answer questions online). And that's not all!
Your photo does indeed show one implant higher than the other, but you are wearing an elastic sports bra that covers your breast scars, and completely invalidates any assessment of implant position inferiorly near your (eventual) inframammary creases. It's impossible to know if the "high" implant is too high because it's pocket is not open enough inferiorly, if your "low" implant has bottomed out, or if you have early capsular contracture or inadequately-created pocket size. No one can give you good advice with this information or without personal examination, which is not possible when you travel out-of-country before ALL of your follow-up visits are complete. Did you receive a reduction of cost because follow-up is not included (nor even possible without more travel)?
Finally, you admit you aren't following your surgeon's advice because "it hurts and I don't like to do it." What other recommendations or follow-up instructions have you decided not to follow? Surgery involves pain, swelling, discomfort, medications, limitations of activities, recommended healing measures like implant movement exercises or wearing of elastic bands, not wearing of bras, etc. Elective cosmetic surgery is not like picking out your desired operation from a vending machine, paying the money, and after some magical things that happen inside the machine, getting your "final result." It involves time and effort and compliance with advice on YOUR part. And, if you "don't like it" and choose to not follow advice and recommendations by the surgeon you traveled to and paid for the surgery, why would you even listen to "free" advice?
I'm sorry, but you should be freaking out. I'm freaking out that you didn't learn your lesson the first time and anticipate doing this again for a tummy tuck. Is your Mexican surgeon so "cheap" that you are willing to risk even MORE "freaking out?"
You should reconsider and see any of many properly-trained and certified plastic surgeons closer to home, both in Canada and the US. BTW, what is the cost of re-operation, re-do surgery, or treatment of complications? You can't get that online, and any monetary savings via surgical tourism is more than offset by even one re-operation for ANY reason.
I'm sorry if this answer sounds harsh, but those of us plastic surgeons in border states end up taking care of all too many surgical tourists who think vacationing and elective surgery is a great idea, and a way to save money to boot! Yours is just a minor example of why this is totally erroneous thinking. What happens if you get a blood clot on the long flight home? Or an infection in your abdominal incision? Or dead skin or belly button from second-hand smoke in the Mexican airport? Who will you ask to "fix" those issues?
Please rethink this and see a plastic surgeon in your own area to ask about your breasts, and find out about a tummy tuck by a local expert. Commit to following all advice, even if it hurts or you don't like it. Even if you had the "King of plastic surgery of Mexico" as your surgeon (and somehow I doubt this if you're going for "cheap"), how can you get evaluation of any problem when you're in Edmonton, and your surgeon is in Mexico? Best of luck--I fear you may need it with the choices you are making. I truly wish you well. Dr. Tholen
