Pain after Alar Rim graft and infection
The photos you provided do not appear to show cartilage extrusion. I don't see any redness in particular but you do have a tick webbed scar which could be the source of irritation and discomfort.
Dr. Jeffrey Epstein Answer
It is difficult to diagnose without seeing you,
but it sounds like exposed rim cartilage that usually heals up
eventually. Something to discuss with your doctor is possible having the
graft removed, letting it heal up, then consider having it replaced.
Infection after nose grafts
This is a very difficult problem that needs a face-to-face evaluation to advise you.
It isn't clear from the photos if the problem is infection, exposed cartilage, swelling or distortion from nasal tip sutures.
