Summary
Arthrocentesis significantly improved pain, mouth opening, and TMJ clicking in patients with internal derangement. This simple procedure offers a recommended treatment option for temporomandibular joint disorders unresponsive to conservative methods.
Area of Science:
- Oral and Maxillofacial Surgery
- Temporomandibular Joint (TMJ) Disorders
Background:
- Internal Derangement of the Temporomandibular Joint (TMJ) is a common condition.
- Conservative management is often the first line of treatment for TMJ disorders.
Purpose of the Study:
- To evaluate the effectiveness of arthrocentesis in improving symptoms of TMJ internal derangement.
- Assessed outcomes included pain reduction, increased maximum mouth opening, and decreased clicking/crepitation.
Main Methods:
- Eleven patients with clinically diagnosed TMJ internal derangement underwent arthrocentesis.
- Patients were followed up at 1 week, 1 month, and 3 months post-procedure.
Main Results:
- Significant improvements were observed in pain, maximum mouth opening, and TMJ clicking/crepitation.
- All observed improvements were statistically significant.
- No serious postoperative complications were reported.
Conclusions:
- Arthrocentesis is a viable and effective treatment for TMJ internal derangement.
- The procedure can be recommended as a simple, chair-side option for cases refractory to conservative management.
