You should contact your rhinoplasty surgeon and discuss the incidence with him or her. Chances are that your surgeon wants to see you in person to assess the extent of your injury. This will determine the optimal timing for your rhinoplasty operation. Best wishes!
I'm sorry to hear about your recent trauma. I would wait a couple of months prior to considering rhinoplasty for best results.
Trauma to the nose is going to cause excessive swelling and bruising, therefore the surgery may need to be postponed. In addition, the laceration to the nose will need to heal on its own prior to undergoing elective cosmetic surgery on the nose. It is always best to check with your operative surgeon.

I would suggest getting in touch with your plastic surgeon asap for an in person consultation. While your photo is helpful, it is impossible to tell the state of your nose after your injury without seeing you in person.
You'll need to visit and discuss this with your surgeon as soon as possible. What is found on your exam and how much your swelling goes down will influence the timing answer. Better to have happened now than afterwards! Good luck!
