I really want a tattoo and my ear surgery is a month and a half from now -- Would it affect my surgery if I get a tattoo now?

It depends on where you want your tattoo and how your recovery is. If you aren’t getting the tattoo on your ear or in the immediate area, and you don’t get an infection, then this won’t affect your surgery. However, it’s always best to ask your operating surgeon.

Hi. 
There is absolutely no problem with getting a tattoo done as long as it is not on the ear or behind the ear directly.

Otoplasty should not be effected by a tattoo unless it is on the ear or very close to it and leads to inflammation or infection. RegardsDr J

You should pose that question to your surgeon. Nobody on this forum knows what specific ear surgery you had (there are many) and where you would like to have your tattoo? It is always best to ask your surgeon what restrictions you have from the operation. Good luck!

So don't have your ear sin tattooed as that may change as the tissues relax after the surgery. Otherwise I can't see it making any difference, unless of course you are lying on your ear for several hours while the tattoo is done. hope that helps. Adam Goodwin

Check  with your surgeon.  He knows your medical history and the procedure that he will be performing. This is his call!
