This problem most likely is due to suture reaction. While the condition is not necessarily fatal, the area needs to be explored and revised with removal of any foreign objects (sutures). There surely must be some surgeon (even a general surgeon) in your area that will evaluate and treat her if she does not have the confidence in her original surgeon.
Ask the Dr if the stitches used were a ble braided sticjed made by a company called Ethicon. I too had similar problems w these sutures in a platysmal plication. I have found 100s of patients so far w similar problems. It is the same co that was sued in a class actionb for a suture called vicryl. I think anither lawsuit is called for! Please contact me at ***@**** I am still haveing issues 2 years post op. Necrotzed fat and lymph nodes etc. 3 surgeries so far! These are FDA approved sutures. It is not the Dr.s faukt rather the manufacturer of these horrible sutures being rejected and causing infections! We need a good attorney!! There are a few out there we just need to find one!
