After a buccal lipectomy, you can expect temporary side effects such as facial swelling and bruising. Both should go away on their own as you recover, which is usually within two to three weeks. The cheekbones will begin to seem slimmer and more sculpted once the swelling subsides. Beyond that, buccal fat removal surgery is a relatively safe procedure.  However, like with any surgery, there is always the chance for unfavorable complications to arise, some of which may demand further surgery.   Potential complications include: Bleeding Problems with anesthesia Lockjaw  Injury to the salivary glands Injury to the facial nerves Cardiac or pulmonary side effects  Asymmetry of the face  Infection is also a potential risk factor. After a buccal lipectomy, a specific mouth rinse may be prescribed to help minimize the risk of infection in the patient. This wash should be used exactly as indicated by your surgeon.
