Crooked nose after revision rhinoplasty 1 year ago, is the soft area scar tissue?

It is not simple to correct crooked nose! Even with the best effort and use of multiple cartilage grafts, corrective osteotomies and careful tip repositioning, deformity can still reccur; part of that may be resistance and memory of soft tissues( providing that all supporting structures were correctly reconstructed). It is best to address this issue with your surgeon and ask for in person second opinion by an expert in rhinoplasty. It always helps to have all documentation and photos before and after previous surgeries available for review. Hope this helps.
