1 month post otoplasty, when can I exercise?

I would definitely ask this question of your surgeon and follow his or her instructions.  In most cases, I would think that you should be able to exercise a month after your otoplasty.  But again, check with your surgeon just to make sure.  

Thanks for the question. After 6 weeks your surgery area is totally healed and yes you can do gym, swimming and also do other activities. I wish you all the best. 

Your surgery is generally too invasive. It is important to minimize manipulation around the ear to avoid ripping out sutures thus diminishing the postoperative result. I say to my patients that they can start exercising after a day or so as long as they do not "bare down", holding their breath while they're extremely straining to lift heavy weights and lying down to do stomach exercise etc. What is important, however, is to don a ski cap or headband to keep the ears closely pressed against the head while you were sleeping. This is to prevent inadvertent separation of the sutures when turning her head on the pillow while sleeping. You must wear this for approximately 6 weeks.

I like to have patients wear ear protection for one month after ear surgery. I release my patients to no contact sports at one month and contact sports at 6 to eight weeks. You should discuss your activity level with your surgeon

One month postop, I would not see contraindications to exercising.  The only thing I would encourage you to delay would be full contact sports.  However, as in all procedures, you should defer to the recommendation of your plastic surgeon.
