How Long Will I Have to Wait After Otoplasty Before Being Able to Use Full Size Headphones?

It is best to follow up with your surgeon in regards to what you can do after otoplasty surgery.  Normally, after 1 month post-op (if no complications), you would be able to do most anything.

As for headphones, I tell patients that they can use their headphones 1 month after surgery.   Nowadays most people are happier using "earbuds" than headphones.   My own children say they are "cooler",   not just fashionably cooler but temperaturely cooler.   Ears get hot under the headphones.
