Chin Back: Mentoplasty Or Orthognathic Surgery?

The lack of a chin ends up causing a feeling of facial disharmony and gives the impression of leftover soft tissues below the jaw, forming what we know as a double chin. Discover the two main treatment options for chin backward and determine which one is the right choice for you.

Chin Symmetry

The chin should touch an imaginary vertical line through the root of the nose. There is some deformity in the front of this line or behind it, which can be more or less accentuated. Many people have the feeling that they have a big nose when in fact, the problem is in the chin. Its poor positioning causes visual changes in the proportions of the entire face, so it is a frequent reason for looking for aesthetic treatments.

Abnormal chin size may be related to changes in facial bone development, bone deformities, trauma, fractures, or tumors. When the chin is positioned behind this line, we speak of retrognathism, which is caused by a more posterior position of the jaw and can lead to sleep apnea. On the contrary, if the chin is advanced to the parameter, we speak of prognathism, usually resulting from a hypotrophy of the maxilla or hypertrophy of the mandible. The first case is what we popularly known as chin back.

Mentoplasty

Mentoplasty is a large jaw, chin surgery (กราม ใหญ่ เสริม คาง which is the term in Thai), recommended for repositioning. The procedure is capable of lengthening, shortening, repositioning, or even modifying the shape of this region.

Therefore, the technique is variable and can be performed by inserting prostheses or cutting bones. In the case of the chin backward, a prosthesis is implanted between the muscle and the bone, stretching the chin.

Orthognathic Surgery

Orthognathic surgery is a procedure that treats dentofacial deformities, aiming to restore the regular aesthetic pattern of the face, balancing its proportions. The specialist loosens the upper jaw and mandible during the surgery, making a new fixation in correct positions using titanium plates and screws.

What Is The Best Treatment?

It is difficult to say which treatment is ideal for chin backward without carefully analyzing the case. Usually, before surgery, 3D planning is performed with the aid of computed tomography. With the aid of technology, this detailed study allows an assertive visualization of the results. Opting for chin surgery alone can lead to poor results, as occurs when advancements greater than 3 to 4 mm are made, which usually produce an aged appearance due to soft tissue damage. In any case, look for a professional you trust. Counting on someone experienced is the best way to your satisfaction.
