From your photo, there's appears to be a significant degree of swelling adjacent to the nasal bones. This could be from Breaking the bones, rasping the bones or swelling within the thicker nasal tissues above the bone that must be dissected off of the nasal bones before the bones are manipulated during the Rhinoplasty. At 6 weeks after the Rhinoplasty these nasal bones should be set and you can perform a simple maneuver to tell, whether the bones are wide or what you see is swelling. However, because you are not my patient, I must advise you to get your surgeons permisiion before trying this maneuver.
Once approved by your Rhinoplasty surgeon, take your index finger tip and apply gentle but sustained pressure to one side of your nose in the middle of the swollen area pushing inwards while counting slowly to 100. In the beginning, the tissue will feel very firm but continue the pressure. At some point during the 100 count, your finger will slowly start to remove swelling, creating a localized indentation as it does so. This continues until your finger contacts the true surface of the nasal bone...that could be 4-7 mm's or more inwards from the swollen skin surface. It's important not to push to hard or to fast but rather use gentle suatained pressure.
This will tell you whether the bone is wide (finger creates a very small or no indentation) or what you see is swelling (very deep indentation is created). If it's bone, a revision Rhinoplasty with bone osteotomies will be required at 6 months (earliest) from the last Rhinoplasty to narrow the bones and move them closer together.
If it's swelling, you still should IMHO do something about it to prevent excess scar tissue formation caused by prolonged swelling within the tissues. Nasal massage performed daily, not exercises, is a form of lymphatic drainage that directs nasal tissue swelling onto the large lymphatic vessels, of the face, for removal. I have all of my Rhinoplasty patients begin this at 1 month post Rhinoplasty and continue for 6 - 12 months depending on the thichkness of their skin and whether it was a primary or revsion Rhinoplasty. You will need to see a Rhinoplasty surgeon in person for these massage instructions. In addition due to the excess amount of swelling over tha nasal bone area, IMHO a kenalog 10 injection should be considered.
IMHO, once again, this has nothing to do with where you had your Rhinoplasty but rather seems more an indication of lack of communication, post op instructions and follow up planning. My pratice is in Beverly Hills but I have a very large international clientelle that travel here for their Rhinoplasty, Face Lifts, Breast Implants etc. and do just fine upon returniing to Europe, Asia, the Middle East and elsewhere because the surgery was performed properly, they were properly instructed on post op care and the lines of communication are always open.
