Maxillary structure may be changed through many operations in maxillary zone. Many surgical interventions such as maxillary filing or elongation of short chin may be applied.

Maxillary surgical interventions generally have aesthetic purposes. In addition, some mandatory processes may be applied together with orthodontists.
Maxillary filing is a maxillofacial aesthetic operation commonly applied in practice. In general, it is done to downsize too long or too wide chins. It is not correct to use it in too long chin operations. Therefore, it is a practical operation fit for tiny maxillary reduction processes.

Maxillary filing operations are performed through an intraoral incision. Operation is done under general anesthesia. It is required to be done in an operating room. It should be applied in a full-fledged hospital. The patient must take care in eating and drinking for some time after the operation. The patient should be kept under control for 1 month. As a conclusion, the patient may have a smaller chin 1 month after the operation.

These gonion operations may apply different techniques. For example, if the jawbone of a person is backward caved in, that zone may be filled in by fillings and silicones. If it is too short, it may be extended frontward by using surgical screws, or if it has protruded too much, it may be corrected by filing operations.

Gonion operation is not a standard type of operation. Type of operation is determined by the patient's maxillary structure. The operation should be designed fit to the facial structure, Patients wishing facial aesthetics or a reduced nose do not generally know that the problem is in jawbone. In general, maxillary interventions are applied for a patient wishing facial aesthetics. The type of operation should be determined according to gonion problem.

Original name of maxillary operations which are publicly known as "jawbone surgery" is orthognatic surgery. Applied to correct the physical problems in face. Warps and deformities may be corrected through interventions to submaxilla and intermaxilla.

Another problem dealt with by orthognatic surgery is intermatching of teeth on submaxilla and intermaxilla. To put it differently, maxillary surgery may be used both aesthetically and for resolution of a physical problem. It is required to apply an orthodontic therapy before dental therapy. As publicly known, it is "dental braces".

An x-ray must absolutely be taken before orthognatic surgeries. Skeletal deformity is determined by x-ray results, and surgery is planned accordingly. In general, the problem is related to being in the forefront or at the back for intermaxilla or submaxilla or both. In reliance upon this orthodontic and skeletal analysis, the surgery is planned.

Maxillary surgeries are performed under general anesthesia. As it is done intraorally, it leaves no operational scars. Surgery takes 1.5 hours if it is related to only one jawbone. If it is required to intervene with both jawbones, surgery takes more than 3 hours. During surgery, patient does not feel any pain.
