Can a rhinoplasty lengthening the columella shorten the philtrum? (photos)

Hello,What you want is not called 'lengthening the columella'. It is actually lengthening the caudal septum so that your columella sits lower than the ala, and will also shorten the philtral length. So, yes, it will improve  your lip aesthetics too. Best of luck!

Your nose and philtrum look normal and you would be taking too much risk vs. the gain. I have done this surgery for 40 years and I would tell you ---fNO surgery,

Tough problem to solve surgically. You have to move the septal cartilage and the medial crura of the lower lateral cartilage forward. This may require grafting of cartilage which can be difficult to secure in a straight line. Your upper lip can be shortened by making an incision following the contour of you ala and the junction of the collumela and excise excess lip skin to pull your lip upward. Can be difficult to disguise this incision and make everything look normal. So, in other words, you need to find a surgeon with a big S on his scrubs to help you out with this so it does not get screwed up in an irreversible manner.
