When your surgery is performed by a qualified plastic surgeon, complications are infrequent and usually minor. However, individuals vary greatly in their anatomy and healing ability and the outcome is never completely predictable.
As with any surgery, complications can occur. These may include infection; excessive bleeding, such as hematomas (pooling of blood beneath the skin); significant bruising and wound-healing difficulties; and problems related to anesthesia and surgery.
There are a number of factors that may increase the risk of complications in healing. In general, a patient is considered to be a higher risk if he or she is a smoker; has a connective-tissue disease; has areas of damaged skin from radiation therapy; has decreased circulation to the surgical area; has HIV or an impaired immune system; or has poor nutrition. If you regularly take aspirin or some other medication that affects blood clotting, it's likely that you'll be asked to stop a week or two before surgery.
