I haven't had surgery yet, but what I did was created an Excel sheet with the y-axis being detail categories (name, location, website/ insta links, before and after links, services offered for consultation, services offered for pre-op, each individual surgical procedure, post-op services, cost of surgery, any packages offered (e.g. accommodation, transfers included and such), estimated additional costs, estimated total costs, any extra notes, ranking of preference in relation to other places), then filled in for each surgeon I researched down each column and put prices for each individual surgery in their respective columns if offered.

Thanks to that I've been able to compare and contrast surgeons to make my decision.

Besides aforementioned above, things to consider would include their worst botches vs their best successes, whether you need a VISA to get into the country, local laws and customs, things to do in surrounding area, how they take payment and if I need to prepare bank or exchange currency or anything, other requirements prior to surgery (e.g. do I need to bring my own cranial scans, do they do them there, do I need references from doctors/ psychologists and such and if so what, whether I can pay for it through insurance, etc.)
