Regarding: "How many times can you get ear otoplasty? I just got ear otoplasty about a month and a half ago and it's better then my old ears but still not great, and I certainly don't feel comfortable putting my hair up. Can I get a second otoplasty? And will the surgeon cut the ear from where the scar was? Or will they have to cut at another spot?"
Just finished answering your other question on this forum.
I really sympathize with your situation but without photographs to understand you, I am struck by your the level of your anger and disappointment. It appears as if you had very little education before the Otoplasty on what to expect.
As regards How many times can you get ear Otoplasty? - I am tempted to pick a number of of a hat but there is NO set number. Each operation produces more scarring and accomplishes less than the operation before it. It is best to get it right the first time around.
Your statement that " got ear otoplasty about a month and a half ago and it's better then my old ears but still not great, and I certainly don't feel comfortable putting my hair up" suggests that EITHER your expectations were much greater than your outcome (so far) or that the Otoplasty result is truly poor.
You really should discuss this with your surgeon. As a patient you are entitled to expect your surgeon to do the best he can, based on his training and experience, but you cannot expect a miraculous transformation from a horrendous deformity. Sometimes, an improvement is all that can be realistically obtained.
