My perspective as a physician:
Bad surgical outcomes occasionally happen. Most of the time, an adverse outcome does not result from any particular deficit of judgment or lack of technical skill on the part of the surgeon. Instead, it usually owes to factors (for example, the patient's capacity to heal) that are often hard to predict and harder to control. For this reason, it is important, as a patient, to understand that there is no such thing as risk free medical intervention, and to know the potential risks of the procedure you are considering. In other words, you might be one of the unlucky few to have a certain complication, but odds are that the complication is not because your physician screwed up, or didn't have enough experience.
Malpractice cases almost always involve more than a bad outcome. There are actually three legal elements that must be present to prove malpractice, but in a less technical sense, malpractice almost always follows some sort of breakdown of communication or toxic communication from the physician. Patients will usually accept a bad outcome, but they will not accept a bad outcome from a jackass.
As I was shopping for surgeons for my upcoming FFS/BA (four days from now!!), I definitely considered experience, but not simply the number of years in practice. I consulted three physicians, one of whom had clearly been in practice longer than all the others. Two performed their cases in outpatient surgical centers and one in a hospital setting. The most experienced physician proposed a technique of brow lift that is far more common for cis-women than it is in trans women. He also made a misogynistic comment during the consult that really rocked my confidence. When my wife and I left the office we both said, "No way" as we walked out. I ended up going with a younger physician with an easy manner, an obvious attention to aesthetic detail and a bit of training under Dr. Spiegel during his residency. The downside of this choice is that he may not have yet encountered the sort of surgical event that happens only once in 1000 cases. On the other hand, I think he has sufficient training and judgment to navigate it.
I hope I'm right, and after the smoke clears, I will be happy to share my recommendation (or non-recommendation) here.
