Hello Chloe12345.You have to ask the surgeon that performed the otoplasty whether he used absorbable or non-absorbable threads. If they were absorbable threads, you can go ahead with the piercing, as the threads would’ve long since dissolved in the meantime. If, on the other hand, non-absorbable threads were used, as is often the case today with the traditional otoplasties and generally with the stitch method, then it depends on where the threads lie in the ear. If the piercing is made at a place in the ear where the threads are, then the threads can be damaged and the ear can protrude again at this place. If the piercing is going to be made in the earlobe and this wasn’t pinned, then it doesn’t matter what threads were used and what method the ear was pinned with, because there wouldn’t be any threads in the earlobe at all.
