Bone grinding and face-lifting surgery is a very strict and meticulous operation, which usually requires very strict qualifications of surgeons, and the whole process of bone grinding surgery also has strict operating procedures.
Before the operation, the lateral X-ray film of the skull should be taken for the patient. On this X-ray film, the skull, jaw structure, tooth-jaw relationship and facial soft tissue should be measured, and the contours of the skull, jaw, teeth and facial soft tissue should be described with cellophane.
Through paper cutting and spelling, we can predict the bone parts, moving distance and direction that need to be moved during the operation, and predict the changes after the operation.
Sometimes it is necessary to take the membrane out of the patient's mouth to make a plaster model of the jaw teeth, and perform simulated surgery on this model. The operation should be performed under general anesthesia. Generally speaking, anesthesia is performed by tracheal intubation. The trachea is completely blocked because of the anesthesia pipe. In this state, it is difficult to inject blood into the trachea. In view of intraoperative bleeding, it is necessary to use an aspirator to suck in time and stop bleeding completely. As long as the operation is standardized, blood can be completely prevented from entering the trachea through the throat, leading to suffocation and death.
