<Before plastic surgery><Before plastic surgery><After molding><After molding>It's been 7 months since I had nose surgery, and my columella seems to be noticeably shorter than before the surgery.
 I understand that the surgical method involves building a columella support using ear cartilage and stacking several layers of ear cartilage on the tip of the nose.
After the surgery, my nostrils became asymmetrical, which wasn't there before.

The photos are in order:

will be revealed over time, right?
I really don't want to have a second surgery, but is there any other answer than surgery to lower the columella?
