Start here: facial reconstruction is usually funded where the cause is cancer, trauma or a congenital condition
Before any conversation about private cost, it is worth confirming what your own health system already provides, since facial reconstruction, where the cause is cancer, trauma, burns or a congenital condition, is usually funded, treated quite differently from cosmetic surgery by most developed health systems.
Where cancer is the cause, this funded pathway typically includes the ongoing surveillance covered later on this page, which private treatment arranged abroad generally does not provide in the same integrated way. This is worth pursuing before paying privately, particularly given how much that ongoing surveillance matters to your long-term health.
