It is necessary to have an objective evaluation of the object of bone-grinding and face-lifting surgery, know fairly well, have the conditions, and make relevant records. It is more important to explain the postoperative effect to customers, so that customers can have a clear direction and understanding of their own requirements. One of the principles of determining the surgical plan according to the individual situation and determining the bone quantity as appropriate is to keep as much as possible and take less.
2. Preparation of bone grinding surgical instruments
Choose surgical instruments according to the surgical plan and surgical habits.
3, bone grinding surgery disinfection
After applying a towel to the patient's eyes and receiving routine disinfection, apply ointment and film to protect the eyes, and wipe the nose, mouth and other parts to prevent the gauze ball from overflowing too much liquid.
4. Determination of anesthesia method for bone grinding operation
If the patient wants general anesthesia, the doctor will cooperate with the anesthesiologist for ECG monitoring and pay attention to the patient's condition at any time. Generally speaking, local anesthesia combined with intravenous administration is much more convenient to operate, but it should be noted that swallowing or inhaling oral liquid into the lungs may cause vomiting or suffocation.
5, grinding bone cosmetic surgery incision
From the opening of the third tooth to the eighth tooth, pay attention to one or two millimeters along the top of the gum when cutting, and be careful not to accidentally injure the mental nerve. You can also design your own opening according to your own habits, but you don't have to emphasize minimally invasive. The smaller the incision, the larger the blind area. The higher the technical requirements, the more difficult it is for the hook knife to get in and out, and the higher the risk.
6. Bone grinding is separated from cosmetic surgery.
The left hand holds the lower edge of mandibular angle with four fingers, and the right hand uses periosteal separator to separate periodontal soft tissue along the incision, and then uses masseter separator to separate it to the lower edge of mandible and the ascending ramus of mandible. At this time, the left hand should be protected at any time according to the strength and direction of the right hand to prevent the separator from penetrating the periosteum and causing bleeding. After separating the external bone plate, insert the mandibular medial separator into the wound and extend to the bottom of the mandibular lower edge. Hook the mandibular body gently and turn the front end of the separator into the inner edge of the mandible. Touch the front end of the separator with your left hand, and push or pull back with your right hand to separate the bone and soft tissue inside the mandible. At this time, the movements should be consistent and the strength should be appropriate. When the separator enters the medial side of mandible, the direction or angle of force should be changed according to the shape of bone. However, it is forbidden to accidentally injure soft tissue, because there is a risk of bleeding, so pay attention.
7. Boning and grinding cosmetic surgery
The instruments for bone grinding and face-lifting surgery are ready to be installed, and the foot switch is placed in a convenient position. If grinding is used, first hold the protective retractor with your left hand and extend it into the incision to separate the soft tissue from the bone body and form a cavity, and place it in the position where bone grinding is needed but not in contact with the bone surface. Grasp the mobile phone head and step on the foot switch, and gently touch the bone surface when the rotary file rotates at high speed. When the bone chips are discharged, grind the bone surface layer by layer with a little force counterclockwise. At this time, you should master the rotary file head.
