Brief summary

The proposed study, which will be carried out on 72 male and female patients, who have reached bone maturity, are younger than 50 years and underwent orthognathic surgical procedures. Patients will be divided into a study group which will receive a regional block with levobupivacaine and a control group that will receive saline as a placebo. The main hypothesis is that regional analgesia in orthognathic surgery contributes to intraoperative and postoperative analgesia. The aim is to determine the real benefit of regional analgesia in orthognathic surgery and analyze the impact of psychosocial factors on results. Various psychological questionnaires, pain scale and questionnaires for evaluation of postoperative recovery will be used in the research. The results of the research could contribute to a better understanding of regional anesthesia in orthognathic surgery and determine impact of psychosocial factors on pain level and satisfaction with orthognathic surgery.
