There are only 3 surgeons who don't have re-do surgeries:
1) The dead surgeon.
2) The retired surgeon.
3) and the liar.
The best surgeons (those who have the fewest complications or re-do operations) are those who obtain excellent training, obtain board certification by real (not bogus) boards, keep up their continuing education, do a lot of the kind of surgery you are contemplating, and have a humble nature that allows them to admit their failings and learn from their mistakes or less-than-ideal outcomes. Educators, whether in academic or private practices, who like to teach other doctors are generally more up-to date, and those who provide charitable surgery for people in less fortunate circumstances tend to be better at their craft, and constantly strive for improvement regardless of their years of experience.
Unfortunately, some surgeons who are on a salary may have less incentive to do better than those whose income depend on their patients' satisfaction and ongoing referrals, but the latter may also be more prone to puffery and self-promotion.
Less than 3% of the 500-700 operations I perform per year require revision surgery, and those are not to fix "botched" surgery, but to improve results, deal with bleeding, place larger implants, or other similar adjustment. Truly unhappy patients with what I would call "botched" results are significantly less than 1% overall, but I do see them. Fortunately, they are very rarely my own patients, and there's a reason for that!
Those "botched surgeries" that I have seen recently: a breast augmentation that was attempted under local anesthesia by a Dermatologist (who called himself a cosmetic surgeon) and only one implant was able to be placed because of patient pain so severe he had to stop halfway through the operation. He tried again the next day (also under local, since he had no hospital privileges and was doing this in an exam room in his clinic) and failed again. Ten days later, the patient still had severe pain in the implanted breast, scars on both sides but an implant missing on one side, and I took the patient to surgery (under general anesthesia) to remove the one implant that he did get in--I found bleeding and possible early infection. Lawsuit pending. Case two: (an American patient who had surgery in Singapore)--facelift, forehad lift, eyelid surgery patient whose "surgical tourist" operation was not done improperly or "botched" at all, just didn't give her the improvement she (reasonably) wished for. Compared to her pre-op photos, there was really NO improvement, so I include this in the "botched" category. I redid everything, so her overseas cost "savings" really was a huge unnecessary expense and additional risk (she was lucky there were no complications other than a poor result).
Even properly-trained, board-certified plastic surgeons have complications or poor results; those with less training have more bad outcomes, or may be more successful at selecting patients who are "easy" cases, or less well informed as to what constitutes a good outcome. Foreign plastic surgeons can be superb surgeons, but there is a higher proportion of substandard training or practices in some foreign countries. You may be lucky enough to choose the best surgeon in a distant locale, but what happens if there IS a problem or complication?
If you are just concerned, good for you for asking these questions! If your gut is telling you to be concerned about who you are seeing, get a second or third opinion! Remember, the bitterness of poor quality remains long after the sweetness of low price is forgotten.
