Summary
This study presents a modified miniplate for treating chronic temporomandibular joint (TMJ) dislocation. The miniplate effectively improved mouth opening and joint function while preventing recurrence in a patient over 18 months.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Biomedical Engineering
Background:
- Chronic temporomandibular joint (TMJ) dislocation involves excessive forward condyle movement, leading to fixation.
- Current treatments for chronic TMJ dislocation have varying success rates and potential complications.
Observation:
- A modified miniplate was designed and surgically placed to treat chronic mandibular dislocation.
- The patient was monitored for 18 months post-surgery.
Findings:
- The modified miniplate demonstrated efficiency in treating chronic TMJ dislocation.
- Postoperative maximal mouth opening improved significantly.
- Recurrence of dislocation was prevented, and articular function was restored.
Implications:
- This modified miniplate offers a potentially effective surgical solution for chronic TMJ dislocations.
- Further studies with larger patient cohorts are warranted to confirm these findings.
- The technique may improve patient quality of life by restoring jaw function.
