Orthognathic surgery, commonly known as jaw surgery, is a precise procedure designed to correct significant misalignment of the jaws and teeth. This correction improves both the function of the bite and the overall balance of the facial structure. The visual journey of this transformation begins with planning and extends through a measured recovery phase to the final, stable outcome. This article will guide you through the expected visual changes.
Visualizing the Transformation
The appearance of the post-surgical face is first created digitally using advanced imaging and planning technologies. Surgeons use cone-beam computed tomography (CBCT) scans to create highly accurate three-dimensional models of the patient’s craniofacial anatomy. This digital data, combined with surface scans of the face, allows for virtual surgical planning (VSP) which simulates the exact movement of the jaw bones.
This process enables the surgical team to precisely predict the effect of the bone movement on the overlying soft tissues. Patients are often shown these simulations to visualize their anticipated profile and facial symmetry before the actual operation takes place. The planning also involves the creation of custom guides and surgical splints, which are 3D-printed to ensure the jaw segments are moved and positioned with sub-millimeter accuracy during the operation.
The Surgical Process and Immediate Appearance
Following the procedure, the patient’s immediate appearance is a direct result of the surgical trauma and the body’s natural response. Patients wake up with significant facial swelling, which is the body’s mechanism for healing, and this is sometimes managed with a specialized cold-therapy wrap around the head. There may be minor oozing from the internal incision sites inside the mouth or trickling of blood from the nose, particularly after upper jaw surgery.
The teeth are often held in their new position using orthodontic elastics attached to the braces, which limits jaw movement and helps stabilize the new bite. Intravenous lines may still be present, and patients may appear drowsy, which is typical of the immediate post-anesthesia phase.
The Recovery Look: Swelling and Gradual Change
Swelling typically reaches its maximum size between 48 and 72 hours after the surgery. This intense puffiness can make the face appear noticeably full and mask the underlying surgical change. Bruising often accompanies the swelling, beginning around the jawline and cheeks before progressing down the neck and sometimes onto the upper chest over the first week.
The most dramatic visual change occurs in the first two to three weeks, during which approximately 60% to 70% of the swelling subsides. During this time, the bruising changes color from purple-black to yellow-green before resolving entirely. The restricted liquid or soft food diet required during this phase can also lead to temporary weight loss and a somewhat gaunt appearance in the body, contrasting with the residual facial puffiness.
By four to six weeks post-operation, the face begins to look much closer to normal, with the remaining swelling becoming subtle and less noticeable to casual observers. A final, minor percentage of swelling will persist. This final swelling takes significantly longer to resolve, continuing to diminish over the next several months as the tissues fully settle.
Final Aesthetic and Functional Outcomes
The true and stable visual result of the jaw surgery is revealed once all residual swelling has completely resolved, a process that can take between six to twelve months. At this stage, the carefully planned changes to the bony structure become fully apparent in the soft tissue contours of the face. The new jaw position results in a permanently enhanced profile, often leading to improved facial symmetry and better definition in the chin and jawline.
Beyond the aesthetic improvements, the final visual outcome is supported by functional gains, such as a correctly aligned bite and improved lip posture. The repositioning of the jaws can also have implications for the surrounding structures, including the nose, where maxillary movement may subtly alter the nasolabial angle.
