Summary
Resorbable plates showed higher complication rates than nonresorbable plates in orthognathic surgery. Despite this, resorbable plates may be preferred for specific patients, warranting further investigation into their clinical application.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomaterials Science
Background:
- Facial asymmetry correction often involves orthognathic surgery.
- Plate fixation is a common method for stabilizing osteotomies.
- The choice between resorbable and nonresorbable plates impacts outcomes.
Purpose of the Study:
- To compare the clinical efficacy of resorbable versus nonresorbable plates in orthognathic surgery.
- To evaluate complication rates associated with each plate type.
- To determine the optimal fixation method for facial asymmetry correction.
Main Methods:
- A cohort of 272 patients undergoing orthognathic surgery was analyzed.
- Patients were divided into two groups: nonresorbable (titanium) plates (n=152) and resorbable plates (n=120).
- Postoperative complications including open bite, infection, TMJ dysfunction, and relapse were recorded.
Main Results:
- Overall surgical success was high (98.89%).
- Complication rates were higher with resorbable plates (18.3%) compared to nonresorbable plates (8.6%).
- Resorbable plates were associated with increased anterior open bite, a trend toward relapse, and postoperative infection.
Conclusions:
- Nonresorbable (titanium) plates demonstrated a lower complication profile in this study.
- Despite higher complication rates, the study concluded that resorbable plates may be indicated for specific patients.
- Further research is needed to refine the application of resorbable plates in orthognathic surgery.
