Rigid fixation of comminuted mandibular fractures
1University of Texas Health Science Center, San Antonio.
Summary
Rigid fixation using plates and screws effectively treats comminuted mandibular fractures, leading to bony union and good functional outcomes. This method offers a viable alternative to traditional fixation for complex facial bone injuries.
Area of Science:
- Oral and Maxillofacial Surgery
- Trauma Surgery
- Orthognathic Surgery
Background:
- Comminuted mandibular fractures traditionally treated with closed reduction and external fixation to preserve periosteum.
- Rigid fixation offers potential advantages in stability and healing for complex fractures.
Purpose of the Study:
- To retrospectively evaluate the success rate of rigid fixation for comminuted mandibular fractures.
- Assess functional recovery, aesthetic outcomes, and complications associated with this treatment approach.
Main Methods:
- Retrospective analysis of 16 comminuted mandibular fractures in 15 patients.
- Treatment involved AO stainless steel reconstruction plates or titanium miniplates with bone screws.
- Fractures included symphysis, body, angle, and ramus locations.
Main Results:
- All fractures achieved bony union without bone grafting.
- Mean maximum incisal opening was 40 mm; satisfactory facial form and occlusion were noted.
- Complications included two infections (13%) and one refracture, all managed successfully.
Conclusions:
- Rigid fixation is a successful and viable treatment for comminuted mandibular fractures.
- This technique effectively restores form and function with acceptable morbidity.
- Further research may explore long-term outcomes and optimal hardware choices.
