Is there a way to close or suture that tiny open flap between my nostril and columella? (Photo)

Hi paige75,
Thanks for asking this question. If your goal is to improve the stepoff between columella skin and nostril, it would require making an incision again and reapproximating the skin edges better. Some skin would be trimmed to make the incision even. I recommend you seek another opinion with a board certified surgeon, ideally someone who has good experience in rhinoplasty. I hope this helps.
