Start here: post-trauma reconstruction is usually funded as treatment of injury
Before any conversation about private cost, it is worth confirming what your own health system already provides, since post-trauma reconstruction, as treatment of injury rather than elective cosmetic surgery, is usually funded in developed health systems, frequently alongside the rehabilitation services private treatment abroad cannot easily replicate.
Where an injury was work-related or followed a road traffic collision, compensation arrangements sometimes fund reconstruction and rehabilitation together, which is worth establishing before paying privately. Where a funded pathway is available, it generally brings with it the orthopaedic input, the therapy and the specialist nursing that this category depends on more than almost any other this site covers.
