There are different categories and classifications of plastic surgery. Some of these procedures are termed minimally invasive. A good example of a minimally invasive or minor procedure is a subcutaneous injection of botox. Other procedures performed by plastic surgeons are more invasive and carry substantially more risk. One example of this type of invasive procedure is breast augmentation. BA is a riskier procedure because the patient usually undergoes general anesthesia. Also, a good rule of thumb is that the more invasive a procedure is, the higher the likelihood of postoperative infection. Minimally invasive procedures have much less propensity for infection and postoperative complications.
Another factor to consider when speaking of risk is the physicians success rate for the procedure. In other words, a procedure for one practitioner may be relatively risk free but for a different practitioner performing the same procedure could be classified as high risk.
