This is not minor surgery. This is major surgery. And I am talking about going into your bone marrow in some cases. Hell, any student will tell you there is severe embolism risk especially if inadequate measures are taken!
In plastics, there is typical routine surgery like a rhinoplasty and blepharoplasty. All these do come with their risks but are less risky if it is your primary surgery and also if you are going to an experienced surgeon. In plastics, you want the BEST doctor you can find or one of the best, because you are dealing with something that is functional, The doctors that perform reconstructive cases need not be as skilled (though they are more skilled in a technical aspect) as the doctors who are trying to improve what already looks normal. To try to change a 6/10 to a 9/10 is really tough and requires extreme precision and artistic talent. Some patients even demand 10/10 to which my professor said that even in his examinations he doesn't get 10/10, maybe 80%!
In plastics, once we venture from soft tissue surgeries to BONE-cutting surgeries, that is where the real risk starts. That is when patients need general anesthesia. Nerve blocks don't work as well. That is when the real risks develop. In fact for some surgeries we have to work with the Maxillofacial surgeons (eg, Eye Orbit Reconstruction and Box Osteotomy). There is a dedicated team of surgeons and nurses to help.
Move on step further, we have this surgery. We do not just cut bone, but we pull them apart. Lets assume you manage to avoid the intra-operative risks (eg, embolism, cutting a nerve), what about the peri-operative risks (infection to the bone, embolism in the first few days post marrow reaming), and recovery period complications (eg, walking with a limp even one or two years after surgery).
If you are 178 or 180 cm as a male, do you want to deal with all this? As a female, I don't think I would. But I am not a male.
