I did revision rhinoplasty using the ear cartilage from my first surgery because I was unhappy with my nose shape and also had nasal congestion.
It was a complicated surgery because the existing silicone was removed too, but the director paid close attention to safety, so the operation went smoothly and I like the result much more.
My nose line actually came to life more after the revision, and my facial balance seems much prettier too.
Most importantly, my nasal congestion improved, making daily life much more comfortable.
If you are deliberating over revision surgery, I strongly recommend entrusting yourself to a director with extensive experience.
