Getting punched in the face after sliding genioplasty?
It is prudent for you to avoid contact sports while healing from sliding genioplasty. It will take a couple months for the bones to heal. Getting hit in the face can cause damage to progress you have made.
The bones take 6-8 weeks to heal. It also depends if you had grafting done as well which could prolong the healing process. I think you should take an x-ray and re-evaluate the healing.
