This is related to the scope of alar resection, especially the nose of Guangdong and Guangxi. Because it has a large amount of alar resection, I will continue to cut to the position of nasal sulcus and then to the edge of nasal columella. This incision is too long, and the incision marks, especially the outer upper part of the alar, are obvious.
The other is to do dot matrix laser in dermatology and do a treatment around the incision. Its advantages are more accurate treatment range, less obvious traces after treatment and quick recovery, but it needs multiple treatments. Nevertheless, more and more people will still use dot matrix laser to treat scars.
