How To Fix Asymmetrical Nose (large Soft Tissue Triangle)? (photos)

Thank you very much for sharing your concerns with us.

The harmony between facial parts makes us instinctively recognize the beauty... without knowing it, without defining it, just a perception that surprises and captivates us.

In this regard, I suggest perform a Closed Rhinoplasty (without visible scars) to treat the tip, base and nasal bridge.
With this procedure you get a delicate nose, better harmonize with your other facial features.

Respectfully,
Dr. Emmanuel Mallol Cotes.-

Filling the soft tissue triangle with soft tissue or crushed cartilage will create better symmetry. See an experienced rhinoplasty surgeon for this. 

Thanks for your question. The soft tissue triangle or facet is the region of the nose where the tip meets the ala. In your case that groove is too deep. This can be corrected by adding additional volume to this area. The best option is to place cartilage in this area to help give the facet a more normal contour. You could also try filler in this area as a non-surgical option, although I believe this is more risky with less predictable results.

A rhinoplasty procedure can accomplish building out the soft-tissue triangle with a morselized cartilage graft harvested from inside the nose.

Thank you for the question and as others have suggested the area you are concerned about can be filled with fascia or crushed cartilage.  So see some experts in your area and compare recommendationsDr Corbin

I am assuming that you've not had previous surgery or nasal trauma which has caused scarring at the nostril rim. This depressed area of the soft tissue triangle can be augmented probably with soft tissue or crushed cartilage but this would be determined after an examination.
