Safe to Play Contact Sports After Otoplasty?

After otoplasty it is a good idea to avoid getting the ears smacked for a month or so. This typically means no boxing, wrestling, cage fighting, etc. Long-term the ears are fine for any kind of sport.

If you are going to go through the time, energy and costs of having an otoplasty, the worst thing you could do afterwards is have someone potentially directly strike the ear. At the very least this will certainly cause a distortion of the ear, and at worst, completely destroy the otoplasty.
Other sports like soccer, basketball, etc, are fine after a few months, but I would recommend no more boxing if you have this procedure done.
