Separating the Perichondrial Flaps from each other after L-Strut Septorhinoplasty

I had a Septorhinoplasty in 2018 that involved a hump reduction and septal extension graft, which used the quadrangular cartilage from my septum as grafting material. In the 4 years since my surgery, my septum (or what remains) is deviated to the right, in a way that is disturbing to touch, and may also be causing a chronic whistling condition. Is a 'septal implant' surgery possible, which would involve separating the flaps and inserting cartilage back into the donor site?
