I underwent Revision Rhinoplasty over a year ago to correct asymmetry in my tip & address a small dorsal hump. Unfortunately, inadequate blood flow during the procedure resulted in an atrophic scar in my upper dorsal area. 4 months ago, my surgeon excised the scar & connected the tissue, improving it but leaving some atrophic scarring. Residual swelling also present. Certain angles are worse. Which laser or scar treatments would you now recommend? Fully ablative CO2? Fractional? Another?
