Bone grinding and face slimming is a popular face modification method at present. Therefore, most girls who are not born beautiful hope to become "artificial beauty" through bone grinding and face slimming, but they do not know much about the process of bone grinding and face slimming.
1、 It is necessary to have an objective evaluation of the object of bone grinding and face thinning surgery. The condition state should be understood in the heart and relevant records should be made. Determine the operation plan according to the individual condition, and determine the amount of bone to be taken out. How to remove it? More importantly, we should explain the postoperative effects with customers, so that they can have a clear direction and understanding of their own requirements. One of the principles is to keep as much as possible and take as little as possible when allowed. How? Take mandibular angle? Cheek fat pad? Or masseter? All removed entities will produce an effect, which is also the factor of creating beauty, and its necessity must be considered.
2、 Preparation of instruments for bone grinding and face thinning: select the surgical instruments to be used according to the surgical plan and habits.
3、 Disinfection of bone grinding and face thinning surgery: after the recipient spreads the towel and receives the routine application and disinfection, the eye is protected by applying ointment and film, and the nose edge, mouth and other parts are fully smeared. Pay attention to prevent excessive liquid overflow of the gauze ball belt.
4、 Anesthesia mode determined by bone grinding and face thinning surgery: if the patient needs general anesthesia, the doctor will cooperate with the anesthetist to monitor the ECG and keep an eye on the patient's condition at any time. However, generally speaking, it will be much easier to use local anesthesia with intravenous administration, but it should be noted that vomit or asphyxia will be caused by ingestion of oral sewage or inhalation into the lungs.
5、 The incision of bone grinding and face thinning surgery: from the third tooth opening to the eighth tooth, pay attention to the opening of one or two millimeters along the top of the gums when removing the knife. Be careful not to injure the mental nerve by mistake. You can also design the opening according to your habits, but you don't need to focus on micro trauma. The smaller the incision, the wider the blind range. The higher the technical requirements, the more difficult it is to get in and out of hooks, knives, etc., and the higher the risk.
6、 Separation of bone grinding and face thinning: the left hand uses four fingers to hold the lower edge of the mandibular angle, the right hand uses the periosteal separator to separate the periodontal soft tissue along the incision, and then use the masseter muscle separator to separate large areas to the lower edge of the mandible and the mandibular ramus. At this time, the left hand should follow up and protect 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 the outer bone plate is separated, insert the medial mandibular separator into the wound and extend it to the bottom of the lower edge of the mandible, gently hook the mandibular body and turn the front end of the separator into the medial edge of the mandible, touch the front end of the separator with the left hand, and push forward or pull back with the right hand to separate the bone body and soft tissue inside the mandible. At this time, the action should be consistent and the force should be appropriate. When the separator enters the inner side of the mandible, the force direction or angle should be changed appropriately according to the bone shape. However, do not pull indiscriminately to cause injury to the soft tissue. There is a risk of bleeding, so pay attention to it.
7、 Bone removal for bone grinding and face thinning surgery: the equipment for bone grinding and face thinning surgery is ready to be installed, and the foot switch is placed in a convenient position. If it is done by grinding, first use the left hand to hold the protective hook and extend it into the incision to separate the soft tissue from the bone body and form a cavity, and then place it at the position where bone grinding is required but not in contact with the bone surface. Grasp the head of the mobile phone and step on the foot switch, When the rotary file rotates at a high speed, it gently contacts the bone surface. When bone chips are discharged, it slightly forces to grind the bone surface layer by layer in the counter clock direction. At this time, it is necessary to master the angle between the rotary file head, the protective sleeve and the bone surface. Only when the angle is appropriate, can the satisfactory cutting effect be achieved.
