What is jaw surgery?
Types of procedures?
Orthognathic surgery , also known as corrective jaw surgery or simply jaw surgery, is surgery designed to correct conditions of the jaw and face related to structure, growth, sleep apnea, TMJ disorders, malocclusion problems owing to skeletal disharmonies, or other orthodontic problems that cannot be easily treated with braces.
What are the types of corrective jaw surgeries?
Maxilla Osteotomy (Upper Jaw)
This procedure is intended for patients with an upper jaw deformity, or with an open bite. Operating on the upper jaw requires surgeons to make incisions below both eye sockets, making it a bilateral osteotomy, enabling the whole upper jaw, along with the roof of the mouth and upper teeth, to move as one unit.
Mandible Osteotomy (Lower Jaw)
The mandible osteotomy is intended for those with a receded mandible (lower jaw) or an open bite, which may cause difficulty chewing and jaw pain. For this procedure cuts are made behind the molars, in between the first and second molars, and lengthwise, detaching the front of the jaw so the palate (including the teeth and all) can move as one unit.
Sagittal Split Osteotomy
This procedure is used to correct mandible retrusion and mandibular prognathism (over and under bite). First, a horizontal cut is made on the inner side of the ramus mandibulae, extending enterally to the anterior portion of the ascending ramus. The cut is then made inferiorly on the ascending ramus to the descending ramus, extending to the lateral border of the mandible in the area between the first and second molar. At this time, a vertical cut is made extending inferior to the body of the mandible, to the inferior border of the mandible. All cuts are made into the middle of the bone, where bone marrow is present. Then, a chisel is inserted into the pre existing cuts and tapped gently in all areas to split the mandible of the left and right side. From here, the mandible can be moved either forwards or backwards.
