The doctor will explain the benefits and risks of your neck procedure during your consultation. Choosing a qualified, experienced surgeon dramatically reduces the risks associated with surgery, which can include bleeding, infection, and the need for revision surgery. Swelling and bruising are common side effects that may last several days, along with tingling, tightness, or numbness.  For more information on risks, talk to Dr. Bared or use a reputable online resource like the American Society of Plastic Surgeons.
