Association between intraoperative factors and postoperative complications in third molar surgery: An observational study

Abstract

Objective: The main objective of this study was to establish the association between risk factors and complications after oral surgery. Material and Methods: A cohort study was developed between April of 2017 and March of 2018 through a register of patients admitted with buccal surgery indication at the San Borja Arriarán hospital, Chile. Results: The incidence of post-surgical complications was 5.8%, with alveolitis being the most frequent. In the bivariate analysis, surgical difficulty was the only intraoperative variable that presented a significant association with the development of post-surgical complications (p<0.05). In the multivariate analysis, no associations were found between intraoperative variables and the development of complications. Conclusion: The concentration of highly complex procedures in professionals with a high level of experience (maxillofacial surgeons) allows low post-surgical complication incidence and prevents intraoperative variables from generating a higher risk of post-surgical complications.
