The availability of surgical procedures on national health services varies from country to country, and even from region to region, so you will need to check locally. Make sure you also check up on any follow up care or further surgery that may be needed.
Costs vary from country to country so, again, you should check locally. In the UK it is estimated to cost approximately £38,000 to include the surgery, devices and immediate follow up care (as at April 2009).
Depending on the country you live in, some costs may or may not be paid by the state.
