My nose bridge is too thin after septorhinoplasy! Will it get wider in time? (Photo)

And it looks thin next to your tip, which is still wide, probably at least in part from swelling from the surgery.I don't know whether it will get wider, but for now there is nothing to do but wait. If you have another operation soon, to try to widen out the bridge, it could be a real disaster. It's necessary to wait for the scar tissue under the skin to soften and mature from one operation before attempting another operation.Later, if it doesn't widen out, it is possible to perform a revision to help.

From your pictures, it does appear that the nasal dorsum is narrow.  It is not likely because of the cast being too tight, rather likely due to how the nasal bones have settled after the procedure.  Make sure to visit your surgeon to discuss your concerns.  It would be wise to wait at least 12 months prior to thinking about revision surgery to allow the body to undergo the healing process.Best wishes.  

The tip of your nose looks significantly more swollen than the bridge, and this could be related, in the early days after the procedure, to a splint that was a bit too tight. Your nose should look more balanced soon, and you will notice changes during the entire first year.If you are still unhappy with the result after that time, you should discuss with your surgeon the available options for improvement.
