Introduction: Orthognathic surgery has been widely used to correct dentofacial deformities. Modifications and improvements in surgical techniques have been constant in recent decades, aiming to make orthognathic surgery safer, more predictable and with the lowest possible morbidity fot the patient. However, like any surgical technique, it is not free from complications and trans-surgical and post-surgical complications. Objective: To identify the complications and intraoperative complications related to orthognathic surgery procedures performed in patients treated at a University Hospital. Material and Methods: A cross-sectional study was conducted based on the analysis of medical records, imaging exams and the surgical description of 100 patients undergoing orthognathic surgery at the University Hospital of the Federal University of Juiz de Fora, from which the variables gender, age, type of osteotomy, intercurrences and surgical complications were analyzed, in the period between February and December 2020. Results: Between the 100 medical records analyzed, 18 presented transsurgical complications. The most frequent intraoperative alterations were the maxillary gap requiring grafting (4%), difficulty in fixing the bone segments (3%) and undesirable mandibular fracture (2%). Regarding complications, these were present in 70% of the medical records, and the most frequent postoperative problem was paresthesia of the inferior alveolar nerve (64%). There was no significant association between the variables gender and age with the intercurrences and complications evaluated. Conclusion: In the medical records evaluated, 70% of complications and 18% transsurgical complications related to orthognathic surgery were present. The most common complication was transient paresthesia of the inferior alveolar nerve associated with sagittal osteotomy of the bilateral mandible branch and Le Fort I/ Le Fort I and chin. The most frequent transsurgical complications alterations were the maxillary gap requiring grafting, difficulty in fixation of the bone segments and undesirable mandibular fracture correlated with sagittal osteotomy of the bilateral mandible branch and chin.
