It sounds like you have fractured your nose given the change in appearance. I would contact your surgeon ASAP for an examination and possible closed reduction if the injury was only a few days ago. They should be able to compare the pictures and examine you to identify what needs to be done.
Nasal fracture one year post rhinoplasty
Dear rhinoplasty problems, I would see your surgeon asap for an evaluation of your nasal fracture. In most cases it is best if the fracture is addressed and reset within the first week to ten days of the accident when possible. Correcting a nasal fracture will not form a new hump on the bridge. Best regards and hope your feeling better soon. Michael V. Elam, M.D.
Fracture post rhinoplasty
It is very difficult to answer your question without seeing you in person and examining your nose – you should consider seeing your surgeon for an assessment. In general the nose may be able to be reset (without major surgery) within 2 weeks of the fracture. After two weeks the bones may be more rigidly fixed and a rhinoplasty may be needed
I need to see a full set of nasal pictures as described on my website. Where is the "slant" located; on your bridge or lower above the tip?
Rhinoplasty to repair a fractured nose
The rhinoplasty procedure can re-set the fractured nasal bones back into alignment. This will involve medial and lateral osteotomies of the nasal bones. Occasionally a spreader graft is also required to be placed underneath the fractured upper lateral cartilage when necessary. A small hump that is present can be filed down same time.
