Will I ever be able to box again? !
The otoplasty procedure involves cuts in the cartilage and permanent suturing to hold the ears in place. Boxing can disrupt the sutures and previous surgery and is ill advised since it will leave deformities. Boxing can also cause cauliflower ear if left untreated. It is best to find another sport.
While being six months after otoplasty is plenty of time to have good healing, you must realize that boxing will pose lifelong risks to your ears whether you have had otoplasty or not. (even though you are unlikely to box the rest of your life) The risk is one of hematoma which can create scarring and cartilage deformity. The ear that has undergone otoplasty may be more prone to this concern in the first year after surgery.
