Can a septal implant be removed safely without damaging the mucosa?

Three years ago I underwent the following procedure to increase air resistance on the right side of the nose: "Right-sided hemitransfixion incision. Elevation of the mucoperichondrium, only on the right side. A couple of cartilage grafts were inserted at the anterior portion of the septum. Closure of the hemitransfixion incision." Unfortunately, since the surgery I have been experiencing persistent pain in an area of the right septum. In that same spot, the mucosa appears thinner and at times I can even see part of the implant underneath. For this reason, I would like to consider removal of the cartilage grafts. I would appreciate your opinion on the following: 1) Is this a difficult operation? 2) Could removal of the grafts further damage the nasal mucosa? 3) Is there a risk that removal could create scarring? 4) Is there a risk that removal might worsen nasal dryness? 5) Is it likely that the grafts have adhered to the septum making removal more complicated? Thank you very much for your time and advice.
