How can a caved in nasal bone be fixed with revision rhinoplasty? (Photo)

I think I understand what caused this problem: uncontrolled vertical fracture of the left nasal bone.You had a small and not very prominent dorsal hump >>> the surgeon shaved just a bit of dorsum >>> the nasal bones did not freed from each other and a synostosis (bone fusion) between them and the septum persisted as a solidary block, aka "closed roof", same as prior to surgery but a bit slimmer >>> until here all is correct, however at this point, when you detect solidary nasal bones, no osteotomy should be attempted without previously relasing the synostosis between the nasal bones, which is best accomplished with the manual Joseph's saws or alternatively (when too large synostosis) under chisel work; since the "roof is open" then osteotomies can be performed safely and efficiently >>> however your surgeon stayed unaware of the closed roof solidarity, which was assymmetrical (happens commonly) affecting only to the left nasal bone cojoined with the septum (left closed roof and right open roof), and he tried the osteotomies, the right one went smoothly but the right one, due to the synostosis, was incompetent all the portion of solidary synostosis and effective below the solidary portion, at which the nasal bone broke from dorsum to maxilla and pinching that area in an unwanted line of fracture (instead of breaking at the radix, as is intended).Solution now is unclear by the images, but for sure needs a very very very good revision rhinoplasty surgeon, refracturing, eventually grafting (spacers) or chiseling the dorsum, temporal fascia graft as camouflage, etc.I notice other issues at other parts of the nose, like pinching of alr cartilage, tip shape issues, etc.If you wish better grounded opinion please do post or send privately well lit, focused and standard images: frontal, both lateral and both oblique views, also underneath the nostrils.
Feel free to request any additional information from me.

Revision rhinoplasty is more difficult than a primary rhinoplasty, so it's very important to choose your surgeon based on extensive experience straightening crooked noses. The  nasal bones are straightened with placement of osteotomies in them. The midportion of the nose is treated with a spreader graft placed underneath the concave upper lateral cartilage in the midportion of the nose which is demonstrated in all of the photographs. The nasal tip itself also appears to be somewhat crooked in some of the photos may need to be addressed as well. There is no perfect nose, just improvement.

Your deviation may be more than just bone. Your middle vault may be involved as well. Best of luck...
