Study population: Review the operation time, blood loss, anesthesia method, anesthesia medication, and postoperative recovery evaluation of the operation record sheet and anesthesia-related record sheet (including the recovery room and postoperative visit record sheet) in the patient's medical record.

Brief summary: Using retrospective medical records to analyze the difference between the analysis of the correlation between operation time, blood loss, anesthesia methods, anesthesia medication, and postoperative recovery time

Detailed description: In Orthognathic surgery, facial bones involved in the operation site are more likely to bleed. In order to reduce the amount of bleeding during the operation, intentional hypotensive anesthesia is executed during the operation.

Because the amount of bleeding is controlled within a reasonable range, the surgical field of vision is naturally clear, which can also make the operation go smoothly, shorten the operation time, and increase the postoperative comfort. Therefore, for orthognathic surgery, the maintenance of intraoperative blood pressure is very important. Using inhaled anesthetics can easily achieve deeper anesthesia, but may increase postoperative nausea and vomiting. Generally speaking, these patients will be fixed with steel wires between the upper and lower jaws after the operation. Postoperative nausea and vomiting will increase the risk of aspiration pneumonia, but intravenous anesthesia can reduce postoperative nausea and vomiting.

This research is a retrospective investigation of medical records. The purpose of this study is to understand the differences in the analysis of the correlation between the operation time, blood loss, anesthesia method, anesthesia medication, and postoperative recovery of patients undergoing surgery during orthognathic surgery. In the future, orthognathic surgery (Orthognathic surgery) anesthesia policy and anesthesia target process guidelines can be formulated, and it can help remind medical staff to make an early and appropriate treatment at any time.

Eligibility criteria: Inclusion Criteria:

* Patients undergoing conventional anesthesia surgery and orthognathic surgery.
