For better or worse, a great deal of cosmetic surgery is subjective. For this reason, it is impossible to offer a money back guarantee or any type of guarantee for that matter. What you consider a botch, may in fact be a standard surgical result that simply does not meet your expectation. You may have a benefit but wish to have more of a result. You may have a complication that is expected and discussed in your surgical consent. An adverse outcome does not mean that your surgeon did anything wrong in the performance of surgery. Of course this is very different than a routine consumer purchase where we are accustom, and often promised, that the toaster, plasma tv, or cell phone we purchase will perform as advertised or the manufacture or retailer will make good on the item.
Take home lesson, your potential cosmetic surgery is not like a routine consumer purchase. I know of no surgeons who extend personal satisfaction guarantees for surgery. You undertake a significant personal risk having a cosmetic surgery. Please pay close attention to what is told to you by your surgeon and their staff. Carefully read and understand what your surgical consent. If you have questions, have those questions addressed. If you are not comfortable having the surgery based on what is described in your surgical consent and the informed consent process, please don't have the surgery. There is no such thing as a risk free surgery, things can and do happen that disappoint us or even disable us as a result of any surgery including cosmetic surgery. This is going to happen at some small rate unavoidably. You assume this risk when having a cosmetic surgery. Often your surgeon will be motivated to help correct issues and may even assume some or all of the expense of revising a surgery. The problems come when you and your surgeon do not agree on the nature of the problem or there is a break down in the relationship.
As Dr Rand correctly points out, in many cases, it is in your best interest to find the right surgeon to address your post-surgical concerns and this may not be the original surgeon. Unfortunately many individuals in this situation find they do not have the financial resources to repair or revise a cosmetic surgery that they are not happy with. It is worth noting that it is not unusual that the fix is even more expensive and surgically intensive than the original surgery. You may be posting because you are in this dilemma. Proceed cautiously and seek qualified second opinions before deciding how to proceed.
