Bone-like Bumps in Bridge After Rhinoplasty

Do not do anything.
This is normal for now.
Any cut bones will develop callus around the fracture site and this can be quite prominent and increase in size for 3-6 weeks after surgery.
Discuss your concerns with your surgeon but give it time for healing to occur. This is too soon to draw any conclusions about the final appearance.

First you are very early in your healing process. You have a long way to go. Soon after rhinoplasty, bumps on the nose are either soft tissue, skin and dermis or they are hard tissue, bone or cartilage. Once the correct diagnosis is made, your surgeon needs to come up with a treatment protocol as you heal over the next year.

The best advice you could get is from your rhinoplasty specialist. Without seeing before and after photos, it would be impossible to give you insight as to swelling or other issues. Wishing you well. Dr Joseph

                  It’s
not unusual for patients to have mild contour irregularities of the nose
following rhinoplasty. In most cases, they can be felt but aren’t easily
visualized.

                  These
irregularities are often due to bone and cartilage remnants where the dorsal
hump was removed. As swelling resolves they sometimes become more noticeable.

                  It’s
important to be patient, because the vast majority resolve with time. In some
cases secondary revisional surgery may be necessary. If you’re concerned about
post-operative nasal contour irregularities it’s important to discuss this
issue with your surgeon. 

Following nasal surgery, if the nasal bridge (dorsum) has been operated on then it goes through several stages of healing. It is not uncommon for some  bone and/or cartilage to be removed by a rasp or other instrument. No matter how gently this is performed, the nose interprets this a traumatic and will begin over ensuing weeks to heal this trauma. If collagen or new bone cells are produced, one may feel or even see a new "bump".  Swelling or old blood will subside in time. But if the new "bump" does not, then sometimes very small droplets of 'cortisone' may help it subside. Or if a sliver of cartilage is present, a small needle carefully angled through the skin might shave it down. But if a visible 'bump' remains after full healing has occured and it bothers the patient, then a secondary  procedure might be needed at a later date to smooth down the dorsum. 

These small fragments of cartilage and bone will likely resorb after your rhinoplasty has healed.  Any remnants can be addressed later. Surgery90210
