Overview
Brief Summary
This study aims to evaluate the efficacy of arthrocentesis in the treatment of internal derangement of the temporomandibular joint (TMJ).
Detailed Description
This work was designed as a prospective case series clinical study. Patients imaging was evaluated with Cone-Beam Computed Tomography and Nuclear Magnetic Resonance at the beginning of the treatment and after the last arthrocentesis.

Eligibility Criteria
Inclusion Criteria
- •TMJ noises and click
- •history of unsuccessful conservative management (NSAID and occlusal bite)
- •occlusal bite still present
Exclusion Criteria
- •degenerative joint disease (such as osteoarthritis, rheumatoid arthritis etc.)
- •history of condylar fractures or previous TMJ trauma
- •TMJ surgery
Outcomes
Primary Outcomes
Pain decrease
Time Frame: baseline (preop), 1 week, 1 month, 2 months, 6 months, 12 months (postop)
Patients were followed up for 1 year. The mean pre-operative pain, using visual analog scale, showed an average decrease of 6.7 at 1 year.
increase in the mouth opening
Time Frame: Baseline (preop), 1 week, 1 month, 2 months, 6 months, 12 months (postop)
The mean maximum mouth opening(MMO) pre-operatively was 15,8 mm and increased to 34 mm immediately following arthrocentesis which increased by 0.5-1 mm at every month followup with mean MMO of 39,4 mm at 6 months. Thereafter it remained consistent till 1 year. The mean increase in the mouth opening at 1 year was 23,6 mm
TMJ click and noises reduction
Time Frame: Baseline (preop), 12 months (postop)
At the end of 1 year, (75%) patients stated no evidence of clicking.
Secondary Outcomes
- number of subjects showing signs of TMJ inflammation or structural alterations at Magnetic Resonance Imaging and Cone Beam Computerized Tomography pre- and postop.(Baseline (preop)- 60 days postop)
