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

The dorsal hump is created by both the contour of the nasal bones (upper half) and the septum (lower half). During hump removal the bone is frequently rasped, or filed, down and the cartilage is trimmed to the appropriate level. Often, when a hump is removed the nasal bones must be narrowed by in-fracturing (osteotomies) because hump removal can leave a gap in between the nasal bones along the bridge.
It's possible that you are feeling uneven edges of the nasal bones where the hump was removed. When osteotomies are performed too high along the nasal side wall (to closed to the brige) the edges can become palpable. Irregularities of the nose are common following rhinoplasty, especially during the early recovery period. With time, these irregularites often resolve as healing progresses. The best thing is for you to visit with your surgeon.

It is not uncommon to have lumps and bumps after rhinoplasty. Sometimes this is blood collected under the lining of the bone. Usually these go away, even if they feel hard. Try some warm compresses on your nose and wait. Noses change a lot during the first six months after surgery. Talk to your doctor about it, but likely he or she will advise you to just give it time. Do NOT use fillers on your nose at this point.

It's possible to develop callus, an early sign of bony healing, that is more prominent in a part of your nose a few weeks after surgery. Swelling is still at play and you should keep an eye on it for the next few months. If at 6 months there is still no improvement, and it feels hard as bone as the swelling has subsided, there is always the possibility that the area that was brought down (the dorsal hump) did not turn out as smoothly as desired, and you may be able to feel a palpable stepoff or ridge between the bone and the cartilage. If so, sometimes a revision may help to soften the transition so that it is not palpable, but should not be considered for 6-12 months after surgery to make sure tissues heal, skin is pliable again, etc. to maximize the chance of success.

Thank you for your question. 
With any nasal surgery, the name of the game is patience. At one week, we would expect you to have quite a bit of swelling and bruising still noticeable and may have trouble breathing out of one or both nostrils. By the end of two weeks, typically, you will still be swollen but look more like you have a bad cold, rather than post surgical. Swelling can take up to a year to be completely gone, however, by 9 weeks you will look very good and should see big difference from your pre-op pics.
