Is fixing alar retraction worth risks? (Photo)

I had a primary rhinoplasty in February 2024. One year and 3 months after the surgery, I still have alar retraction in the left nostril. This makes my nose appear assymetrical from the front, and the nose looks less attractive when viewed from the left profile. However, the retraction is mild. My surgeon has offered to do a graft with skin (or cartilage?) harvested from my ear for only the cost of hospital fees. However, I am not sure it is worth the risks (scarring, failed graft, etc.) Would you recommend a revision for this outcome given the risks?
