I read that and thought “ok yeah I guess that’s possible” but then I thought about it more and I think honestly this only applies to magnets encapsulated in materials like silicone or parylene which have imperfections that promote rejection and / or biofouling. The xG3 and certainly the Titan should never result in this.
A properly closed and healed incision should mean the xG3 or Titan is “in for good” and should not grow out. The only other possibility I can think of is that they never seated properly and caused constant pressure / force over time which in turn caused partial or full tissue necrosis which opened a wound for the magnet to be pushed out of.
I guess my question at this point is - what types of magnets have you heard of that have grown out? Are they silicone coated?
