I'd emphasise the point made earlier, the quality of the surgeon. Their experience, success rate, everything. And make sure the person you meet is the person performing the operation, you don't want to be a training exercise for a student.
Remember, this isn't a simple remove / reduce operation where the surgeon follows set steps - there is a lot of judgement involved. Wrap, size of wrap, tightness, the lot. And if the surgeon gets it wrong through inexperience it is you who is paying the price.
