7 months post-op. My straight/solid rib rhinoplasty is warped. Is shaving down or screwing to the bone a good option? (photo)

On this profile view, you've got that unnatural-appearing bump just above the tip. Seems to me, though, that if that bump were shaved down, your nose would look very long. I'd think about considering a significant elevation of the tip, too. Elevating the tip could have other benefits.
The bridge of your nose looks a little concave to me. If the tip comes up, the nose is overall smaller, and the convexity wouldn't be as important -- it might even look right with the smaller nose. Then, making a nose smaller just tends to de-emphasize any other asymmetries or problems. Also, we don't see a frontal view, but if the graft is off-center from the frontal view, and that asymmetry can't be corrected completely, then again, elevating the tip can make the nose look less crooked.
I'd like to see what that would look like with a morph, but this one photo isn't good enough for making a morph of your nose.
Don't really know what screwing the graft to the bone would do. The problem seems to be close to your tip, which is far away from any bone.
Finally, how thick is the graft? Usually, rib is used to make a big elevation of the bridge, but your bridge seems low-ish to me, at least from this photo. Why was rib used in the first place? Was the rib operation a revision?
Seems I asked more questions than you did! Sorry. I'm trying to help...
Remember that rhinoplasty is an exquisitely difficult operation to get right, and you should only have more surgery if you are able to make yourself very confident in your surgeon's skills. The changes I described above require advanced techniques, requiring skill that most plastic surgeons don't possess with expertise. For most noses, it's much better to not have surgery than to have inexpertly-performed surgery. Read my essay on how to stay out of trouble while selecting a rhinoplasty surgeon. For those who have had previous surgery, it also discusses how to tell whether your first surgeon should be performing your revision.

I can see the point from the graft right above the nasal tip.  There are two option.  Shave down the point, redo the graft, or remove the graft entirely and do something else altogether.  I don’t  think trying to screw that part of the graft will work at all.

Unfortunately rib cartilage warping is a fairly common and difficult to fully control problem, especially if the cartilage graft is taken from a younger patient. Your surgeon knows the intricacies of your graft and your surgical details the best, thus I would rely on his or her advise. Couple of options that come into mind:- shaving the bottom protruding portion of the cartilage down- probably the quickest option but doesn’t prevent from further warping. Probably shaving the excess, scoring the cartilage partially to break the tensile forces and suturing it to the cartilaginous nasal structures has the best chance with this route -replacing warped graft with another rib cartilage graft- again doesn’t fully prevent from warping problem. Options here include cutting the cartilage differently, reinforcing the graft with permanent sutures, suturing the bottom portion and maybe fixing the top portion with K wire or a screw after placement, or using a cadaveric cartilage graft which may be less prone to warping than your own. - removing the graft and using a silicone dorsal implant (not in favor of those but in certain instances they work fine and may be a good option)- removing your graft, mincing it into small pieces, wrapping in fascia or Alloderm and placing it back- this will not provide structural support but aesthetically works well. Hope this helps. Dr. O
