What is the procedure for a bone shaving surgery?
Disease description:
I've never been quite satisfied with my face shape, as I feel my jawbone is too wide. I've heard that bone-reduction surgery can help improve this, and I'd like to learn more about the specific procedure. How is this surgery performed? Will there be a lot of pain during the operation?

Orthognathic surgery, medically known as jaw and facial contouring surgery, is a surgical procedure that improves the facial contour by altering the bone structure. This surgery is primarily performed on areas such as the mandibular angle and zygomatic bone to achieve the goal of reducing the facial outline and improving facial shape. The following is a treatment process for this surgery:
1. Comprehensive evaluation: The doctor will use imaging examinations such as facial CT scans to understand the patient's bone structure and formulate a surgical plan.
2. Health assessment: Includes blood tests, electrocardiogram (ECG), etc., to ensure the patient's overall health and suitability for surgery.
3. Detailed consultation: Understand the patient's expectations to ensure clear surgical goals.
4. Anesthesia: Prior to the surgery, local or general anesthesia will be administered to ensure patient comfort and safety during the procedure.
5. Incision: The surgeon will make small incisions locally, usually near the mandibular angle. The muscles from the oral cavity to the facial skin will be carefully lifted to separate the periosteum and muscles, thereby exposing the bones to be removed.
6. Bone reduction: Using specialized surgical instruments, the surgeon will cut or grind away excess bone tissue to achieve the desired improvement in facial contour.
7. Hemostasis and wound cleaning: After bone reduction, the surgeon will perform hemostasis and apply bone wax to the wound to promote natural bone healing. Any bone fragments or debris generated during the surgery will be thoroughly rinsed with saline to ensure cleanliness of the surgical area.
8. Adjustment and dressing: Postoperatively, the surgeon will adjust according to the changes in the patient's masseter muscle and bone structure. If necessary, part of the enlarged muscle may be removed. Finally, the surgical site will be dressed to control bleeding and help shape the new contour.
9. Postoperative cold compress: Apply cold compresses in the early postoperative period to reduce swelling and pain.
10. Dietary adjustment: Initially, consume mainly liquid or soft foods, avoiding hard or difficult-to-chew foods.
