Abstract
Introduction
The objectives of this 5-year retrospective study were to evaluate the indications and risk factors for the removal of titanium miniplates following osteosynthesis in orthognathic surgery.
Methodology
The records of 1252 consecutive patients (5779 plates) undergoing orthognathic surgery between January 2015 and July 2020 were reviewed. The risk factors considered in the study included age, sex, smoking habits, jaw movement and rotation, third molar removal at the time of the surgery, plate location and plate manufacturer.
Results
681 patients had bimaxillary surgery, 466 patients had a bilateral sagittal split osteotomy and 105 patients had a Le Fort I osteotomy. In total, 341 genioplasties were performed. 78 patients required plate removal (6,2% of all patients). A total of 107 plates were removed (1,9% of all plates). All patients had their plates removed within a year. Infection is the most important reason for plate removal in 71,8% of the patients (56 patients, 68 plates). 12 patients had their plates removed because of subjective complaints (15,4%, 20 plates). The average time between surgery and plate removal was 73 days.
Conclusion
Age, thirdmolarremovalduringsurgery, mandibleplatesandmandibularrotationweresignificant predictors for plate removal. These factors should be taken into consideration for every orthognathic patient. This study reports a low incidence of plate removal compared with previously published reports.
