Introduction
Mandibular osteotomy surgery is designed for patients with facial mandibular defects, helping to create smoother jawline contours and enhance overall facial aesthetics. The surgical procedure includes general anesthesia, making incisions to expose the surgical site, bone grinding, hemostasis, and suturing. During the operation, it is essential to protect nerves and blood vessels and ensure symmetrical bone cuts. Additionally, for greater safety and optimal outcomes, it is recommended that patients undergo this surgery at a professional medical facility.
Mandibular contouring surgery is intended for patients with facial defects in the mandible, helping to create smoother jawline contours and a more aesthetically pleasing facial appearance. The specific procedure for mandibular reduction surgery is as follows:
1. General anesthesia: Clinically, bone reduction surgery is generally performed under general anesthesia with tracheal intubation.
2. Incision and dissection: An incision is made inside the mouth near the angle of the jaw. The facial skin and muscles are lifted from within the mouth, and the muscle is separated from the periosteum to expose the targeted bone area.
3. Bone reduction: Based on the planned amount of bone removal, the surgeon marks the cutting lines and uses a long-handled oscillating saw to trim the mandibular angle along these lines, then smooths any sharp edges. If necessary, part of the inner layer of the masseter muscle or excess fat may also be removed according to individual needs.
4. Suturing: Bone wax is applied to the bone surface to control bleeding, followed by compression using medical cotton balls to achieve hemostasis. Finally, the incision is sutured closed, completing the surgery.
