Jaw surgery, known as orthognathic surgery in the medical community, is an umbrella term for a variety of surgical interventions to correct abnormalities and structural issues with the jaw and facial bones. Sometimes surgery is necessary because a person is born with abnormalities or misalignments affecting function, including how they talk and chew. Other times, there are cosmetic reasons why jaw surgery might be recommended if the abnormalities impact a person’s overall appearance. Jaw surgery can also be a necessary requirement after a patient is in an accident or experiences some type of trauma, with surgery being a way to reconstruct the damaged areas in the jaw and facial region. An oral or maxillofacial surgeon performs jaw surgery, and the surgeon often works in collaboration with an orthodontist overseeing the patient’s case. Not only is the goal to improve jaw function, but it can also be an effective way to improve aesthetic issues related to the structure and appearance of the jaw area. Jaw surgery is usually only recommended when other treatment options are insufficient for correcting a patient’s jaw. For example, patients with severe misalignment of the teeth and jaw, as well as congenital or developmental conditions or facial asymmetry, can benefit from a correction of the jaw positioning to improve both function and aesthetics.
A thorough evaluation must be done before determining whether jaw surgery is necessary. This examination process includes x-rays of the teeth and face, 3D imaging, and digital models to plan the desired outcome of the surgery. When a surgeon completes a comprehensive assessment, they are able to create a detailed treatment plan that is uniquely designed to match each patient’s individual needs. Because the surgery is intensive, patients are put under general anesthesia to ensure they are comfortable and still during the operation. The surgeon will make incisions inside the mouth to minimize the visible appearance of scarring in the future. Sometimes, external incisions might be necessary and made in discreet locations, such as under the jawline. Specialized methods are used to reposition the jawbone and fix the misalignments. For example, the jaw might be moved forward or backward, or it might be necessary to place bone grafts to fill gaps where a portion of the jawbone is missing. The surgeon might need to stabilize the bones using plates, screws, or wires so that everything maintains the correct alignment during recovery. Usually, these surgical interventions are combined with orthodontics and restorative dentistry to create an optimal smile for each patient. The results can be transformative, but there is also a significant recovery time that lasts for a few weeks.
