Any operation is risky. The risks of orthognathic surgery include: anesthesia risk, surgical failure risk and intraoperative accidents, postoperative edema and infection risk, postoperative recurrence risk. These risks are the main reasons for the limitation of orthognathic surgery.
Orthognathic surgery usually adopts general anesthesia, and the risks of anesthesia mainly include accidental injuries of teeth, lips and vocal cords caused by allergic reaction and poisoning reaction of anesthetic drugs: severe anesthesia accidents with hoarseness after surgery can lead to respiratory and circulatory system failure and even life-threatening. Experienced anesthesiologists will explain to patients before operation to minimize the risk of anesthesia.
Orthodontists and orthodontists should have good cooperation. Orthodontists prepare for occlusion before surgery, orthognathic surgeons determine the best surgical plan after careful measurement and model surgery before surgery, and accurate and gentle operation during surgery is the only way to reduce the risk of surgical failure. In order to reduce postoperative edema and infection, orthognathic doctors should try their best to reduce surgical injuries, shorten the operation time and stop bleeding carefully. And use drugs to prevent and control the postoperative infection process.
And the risk of postoperative recurrence can not be ignored. The operation only changed the size and position of the jaw, but the related muscles and tongue did not change correspondingly, which required the patient to train himself after the operation to gradually adapt to the new jaw tissue. However, patients often cannot persist in this process, and the risk of recurrence increases. In addition, not completely getting rid of bad oral habits is also an important reason for recurrence. Therefore, patients should follow the advice and requirements of orthodontists in this regard and establish self-awareness to prevent recurrence.
To sum up, although surgery is risky, modern orthognathic surgery has developed into a mature discipline. Orthodontists, orthognathic surgeons and anesthesiologists have mastered the skills of preventing risks and established the confidence of successful treatment for patients.
