First of all, facial paralysis may occur after mandibular angle grinding surgery: when mandibular angle grinding surgery is performed, the mandibular nerve is easily damaged, which directly dominates the perception of lower teeth and lips. It is the main culprit causing pain after mandibular angle grinding. If it is pulled during mandibular angle grinding, it will cause temporary paralysis of lip perception after mandibular angle grinding. And once it is damaged, it may cause permanent perceptual paralysis. Do you know? Let's take a look at it continuously. Secondly, after mandibular angle grinding and plastic surgery, it may also lead to left-right asymmetry of the face: during mandibular angle grinding surgery, some doctors can't accurately calculate the width of the removed bone, and the face of the human body itself is not completely symmetrical. If the mandibular angle grinding surgeon is not skilled or negligent, it will cause the asymmetry of the width of both sides of the face to increase. Therefore, experienced mandibular angle grinding surgeons should not only familiarize themselves with the facial bone structure, but also take X-rays before mandibular angle grinding to clearly understand the unique bone structure of the beauty seekers. Now you have a basic familiarity with the right questions. Thirdly, there will be hematoma after the mandibular angle plastic surgery: every operation will involve a large number of blood vessels and nerves, and even if the bleeding is fully stopped, it is very easy to appear bleeding after the operation. Mandibular angle grinding surgery is no exception. Therefore, in general, when the mandibular angle is grinded and sutured, the doctor will place a drainage tube to lead out the congestion in the wound. If the drainage tube is placed in a different position, or the hemostasis work is not done well, it is especially possible to accumulate a lot of blood stasis on the face after mandibular angle grinding, resulting in hematoma. Some even have massive bleeding. Finally, after mandibular angle grinding surgery, facial muscles may be distorted: damage to sensory nerves will cause sensory paralysis, while damage to facial nerves will involve facial muscle movement. For example, as shown in the picture of mandible, some nerves grow close to the periosteum during mandibular angle grinding surgery. Once the mandibular angle grinding surgeon fails to separate the nerves from the periosteum, there will be serious consequences such as eyebrow lifting obstacle and unilateral frontal muscle paralysis. In fact, the purpose of introducing these risks to you is to tell you that we should choose a professional and regular plastic surgery hospital when performing mandibular surgery, so that there will not be so many risks.
