Can A Solid Rib Graft Be Done After An Initial Diced Cartilage Rhinoplasty?
Q: Dr. Eppley, I’m an Asian patient who underwent augmentation rhinoplasty 4 months ago with diced rib cartilage, but the augmentation isn’t enough. When I consulted the surgeon, he said the diced cartilage technique either undercorrects or overcorrects the nose. With bloc rib rhinoplasty, it’s easier to control precision of the augmentation required but subject to warping. Is that true? I’m planning to have another revision to augment the height again using bloc rib cartilage. What do you think? How long more do I have to wait for a revision? I just wish to push for more height. Thanks.
A: In general, diced cartilage for total dorsal augmentation can be a very satisfactory technique if the amount of height required is no more than 3 or 4mms. For most Asian rhinoplasties, sufficient dorsal height is usually closer to 7mms. Thus a diced cartilage dorsal augmentation may be insufficient because the push of the skin at this amount of augmentation is significant and the diced cartilage construct is not strong enough to resist it. So even if the diced cartilage roll was 7mm in height, it would be pushed back down and flattened somewhat. A bloc cartilage graft is much more successful in displacing the dorsal nasal skin upward the required amount for the obvious reason thatit is solid and can not be deformed. While it is true that bloc cartilage has the risk of warping, the key to prevention of that problem lies in the harvest. Rib grafts are absolutely needed and getting a fairly straight cartilage graft of 3.5 to 4cms in length can be difficult but it can be done.
As for the timing of the revision, since you know you desire more now that the initial swelling has gone down you could proceed at any time with a revisional rib graft rhinoplasty.
