Everything You Need to Know About Different Types of Jaw Surgery

Jaw surgery, also known as orthognathic surgery, is a procedure performed to correct various dental and skeletal issues related to the jaw. The specific type of jaw surgery recommended will depend on the individual’s condition and the desired outcome. Here are some common types of jaw surgery:

1. Maxillary Osteotomy

Maxillary osteotomy is a surgical procedure that involves repositioning the upper jaw (maxilla). It is performed to correct conditions such as an open bite, crossbite, or a significantly receded or protruding upper jaw. The surgeon will make incisions in the upper jawbone, reposition it, and secure it in the new position using plates and screws.

2. Mandibular Osteotomy

Mandibular osteotomy is a surgical procedure that involves repositioning the lower jaw (mandible). It is performed to correct conditions such as an overbite, underbite, or a significantly receded or protruding lower jaw. The surgeon will make incisions in the lower jawbone, reposition it, and secure it in the new position using plates and screws.

3. Genioplasty

Genioplasty, also known as chin surgery, is a procedure performed to reshape the chin. It may involve reducing or augmenting the size of the chin or adjusting its position to improve facial balance and harmony. The surgeon will make incisions either inside the mouth or externally under the chin, reposition the chin bone, and secure it in the new position using plates and screws.

4. Orthognathic Surgery

Orthognathic surgery refers to a combination of maxillary and mandibular osteotomies performed together. It is often recommended for individuals with significant skeletal discrepancies between the upper and lower jaws. The surgery aims to align the jaws properly to improve facial aesthetics, bite function, and overall oral health.

5. Temporomandibular Joint (TMJ) Surgery

TMJ surgery is performed to treat certain severe cases of temporomandibular joint disorders, such as chronic jaw pain, jaw joint dysfunction, or structural abnormalities of the jaw joint. The specific procedure will depend on the individual’s condition and may involve joint repositioning, joint replacement, or arthroscopy to address the underlying issues.

It’s important to note that jaw surgery is a complex procedure that requires careful evaluation, planning, and coordination between an oral and maxillofacial surgeon and an orthodontist. The specific type of jaw surgery recommended will depend on the individual’s specific needs and the severity of their jaw-related issues.
