What Xiao Chang said is the scientific name of mandibular protrusion, this kind of dental deformity is mainly caused by heredity or local trauma in infancy. A protruding jaw greatly affects the shape of the face, making it unsightly. Orthodontic surgery can be a good solution to this problem, as described below.
What is jaw protrusion correction surgery?
In clinical practice, the mandibular protrusion correction surgery often removes the protruding mandibular tissue by surgical osteotomy, so that the maxilla and mandible are in an ideal anterior-posterior position. To remove the teeth that hinder the osteotomy, the whole operation is more traumatic. Will the mandibular protrusion surgery leave scars?
The mandibular protrusion correction surgery can be performed with an intraoral inferior gingival incision or a skin incision parallel to the lower chin. When an incision is made at the inferior gingiva, the lower lip and the mucoperiosteal should be turned down and back together to perform degloving surgery. , in order to expose the chin, although this approach can avoid the appearance of scars, but it is slightly more difficult and easy to damage the mental nerve. An incision is made at the skin under the chin. Although there are traces of postoperative skin sutures, it is not easy to be seen.
The specific process of mandibular protrusion surgery
Taking the skin incision method parallel to the submental border of the chin as an example, the mandibular protrusion correction surgery involves incising the skin until the periosteum, separating along the superficial layer of the periosteum to the periphery to reveal the protruding chin, and removing part of the mandible according to the aesthetic point of view and the actual situation of the patient. After the excess protruding bone was cut off, the bone wound was repaired into a round and blunt shape with a bone rasp, and bone wax was applied to completely stop the bleeding. Then, the excess skin and subcutaneous tissue were excised, sutured layer by layer, fixed with pressure bandage, and the sutures were removed one week later.
