Summary
Temporomandibular joint (TMJ) arthroscopy effectively treated closed lock, reducing pain and improving mouth opening. This minimally invasive procedure offers significant symptom relief for TMJ disorders.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Arthroscopy
Background:
- Temporomandibular joint (TMJ) closed lock is a debilitating condition.
- Arthroscopy offers a minimally invasive approach to diagnose and treat TMJ disorders.
Purpose of the Study:
- To describe the clinical experience of arthroscopy in treating TMJ closed lock.
- To evaluate the efficacy of TMJ arthroscopy in pain reduction and improving mouth opening.
Main Methods:
- Retrospective analysis of 12 TMJ arthroscopies in 10 female patients (mean age 31.2 years).
- Antero-lateral approach utilized for joint entry.
- Clinical findings documented, including adhesions, disc displacement, and articular surface changes.
Main Results:
- Common findings included adhesions (64%) and fibrillation (64%).
- Significant pain reduction observed in 88% of patients with pre-arthroscopy pain, with 38% experiencing complete resolution.
- Mean maximal incisor opening increased by 40.3% two weeks post-procedure.
Conclusions:
- TMJ arthroscopy is an effective treatment for closed lock, leading to pain relief and improved function.
- The procedure demonstrates positive outcomes in improving mouth opening and reducing TMJ symptoms.
