Whenever you have an operation, there are always potential side effects. Some are normal reactions of your body:
Pain: Pain varies from patient to patient and depends on your pain threshold. If you have a sedation or a general anesthesia, the anesthetist will inject in your drip strong long lasting pain killers. After your surgery, you will be given tablets of pain killers, generally for the next 7 days.
Scars: For any operation, there is a scar. Your surgeon will show you during the consultation the type of scars you have to expect. He will tell you where they will be, how large they will be and their normal evolution. Certain patients for genetic reasons don't heal very well and their scars, instead of being very discreet, tend to be quite red, or even with time get larger (hypertrophic scars) and very lumpy (cheloid scars). You have to tell your surgeon if you had problems with scarring in the past, so that he can minimize the risk of bad scarring.
Swelling: After your surgery it is normal to have a swelling on the operative site. This swelling will last several weeks or even months. The duration of the swelling depends on how aggressive the surgery was and how your body reacts to it. To minimize the swelling you are often asked to wear a compression garment for a few weeks (to be specified by your surgeon). Also massage sessions are recommended after surgery to have a quicker disappearance of this swelling.
Bleeding: Usually, for a lot of operations, at the end of your surgery, your surgeon will leave a drain in place. This drain will stay in place a few hours and will allow any oozing coming from the operative site to be collected in a small container. But sometimes, there is a real bleeding starting after the end of the surgery. If it happens, you need to go back to theatre so that the bleeding can be dealt with by your surgeon. It is important to tell your surgeon during the consultation if you are taking any blood thinners or anticoagulants as they need to be stopped before your operation. It is also important to have a blood test before surgery to detect any potential problem in your coagulation capacity.
Infections: Infections are a real medical problem. Prevention is very important: before surgery you need to have a blood test to check if you already have an ongoing infection and a swab to check if you have resistant bacteria on your skin (MRSA). Then it is recommended to take a shower with antiseptic before your operation. During surgery, the anesthetist will give you an IV antibiotic. After surgery you will be given tablets of antibiotics for a week and instructions regarding the change of your dressings. Changing of the dressings regularly by a nurse is very important in the prevention of infection.
These are the general risks of any procedure in plastic surgery.
They are also specific risks for every procedure that will be explained further.
