2 months after rhinoplasty and my nose is wider than before. I am afraid this will be its new shape. (Photo)

2 months after a rhinoplasty is a too soon to judge your final results.  It is possible that you may have some uneven or significant swelling at this
time. Depending on the nature of your surgery, it can take up to one year
to see the final result. This is especially true if tip work was
performed during your surgery. I would give it some time and see how the
healing progresses, and speak with your surgeon to get his or her opinion.
Thank you and good luck with your recovery!

The common causes for wide noses after Rhinoplasty are inadequate osteotomies for mobilization of nasal bones ,Use of expander grafts for supporting mid-Vault also broadens nose,2 months is early to predict results ,May be at 6 months situation will be more clearer, Tip swelling may take up to a year for subsiding

The chances are that the nose looks wider because of post operative swelling and it can take upto 6 months for swelling to leave the bridge of the nose.  The tip of the nose can remain swollen much longer.  If you had a big hump on the bridge of the nose that was removed but the nasal bones were not narrowed by performing "Osteotomies", the bridge CAN look wider after surgery.  If the Rhinoplasty were done with the closed technique and the lower lateral cartilages were not sutured together with an inter final suture then the tip can look wider after surgery.  You should speak to your surgeon about these matters and he/she will be able to clarify things for you.  Most of all, you need to give it more time to allow swelling to recede.
