Scar tissue is causing columella asymmetry. How would scar tissue be accessed and removed during a closed revision rhinoplasty?

Hello, doctors. I have a question concerning how access to the columella, specifically to the area underlying the columella skin, is obtained during a closed rhinoplasty. One of my revision rhinoplasty issues includes a hard lump of scar tissue that formed under the columella area that causes my columella to look asymmetrical and skewed and was not addressed during my primary rhinoplasty. How might this scar tissue mass be accessed and removed through a closed revision rhinoplasty?
