3 weeks post-op. I can't open my mouth all the way. What is the usual outcome of a situation like mine? (photos)

At three weeks out from surgery, it is normal to have swelling that can lead to tightness and temporary inactivity of the nerves. However, it is important to follow up with your surgeon to fully assess the activity of your nerves and your skin. Sometimes the hibernation of nerves lasts a few weeks and sometimes can take longer. Follow up regularly with your surgeon to follow up and make sure there is improvement of the nerve function.

Thank you for your question.    I recommend to see your doctor. This condition can be cause for a number of reasons but you need to be seen in the office to be asses properly.
