It sounds to be like your implant placement technique was not adequate if not this would not occur under normal circumstance.
My nose revision was done at Dream and done perfectly. I previously had extrusion from a full autologous rhinoplasty done in Los Angeles by Charles Lee, where the cartilage had tore and pushed out of my upper bridge. So you can imagine my tissue was very thin and much thinner than yours. As part of my consultation with Dr Park, we came up with 3 plans of treatment.
Plan a) ultra soft silicone placed under the periostiem. irradiated rib cartilage for the tip. Should my periostiem be damaged from the previous surgery we would then use scar tissue to seal and protect the implant.
Plan b) should my tissues be far too weak for the ultra soft silicone we would then use auto dermis as the replacement.
Plan c) this is what ended up happening. The ultra soft silicone i picked was too high for my thin skin to sustain and my periostiem was damaged. Auto dermis was also not a good fit for my nose. Hence the final method was discussed while i was awake on the operating table, feeling no pain and being walked through each step while dr park was working on my nose:
2.5mm Ultra soft silicone shielded and held down by scar tissue
0.5mm Tuto Fascia graft above the silicone and scar tissue to seal the hole from extrusion and grow into my damaged tissue. Thus protecting and strengthening it.
Irradiated rib strut in tip with a small piece of auto dermis in front of it to protect the tip tissue.
Shield Graft for added protection made with my own harvested ear cartilage
alloderm in collumela to lengthen the nose to reach the 3 point ratio.
Mine is considered reconstructive surgery as you can imagine how complex it is. If your tissues is really as thin as you say, then you should consider the use of tuto fascia to strengthen it like I did. The only side effect of tuto fascia is that it can, at irregular intervals increase blood circulation in the area and make the nose a little red. This comes and goes temporarily until the 6 months mark. It can also easily be covered with a thin layer of make up.
I was offered to try autologous dermis from Dr Park too. However he advised me that the resorption is unpredictable and depends on the patient's body. Plus i didn't want anything cuts to my booty region lol especially since I am very prone to keloids on the body. So i opted out of that method.
So anyways I hope sharing my method helps you consider what can be done for your situation. I wrote a review about what occured during my surgery if u want more detail.
