This study aims to evaluate the efficacy of arthrocentesis in the treatment of internal derangement of the temporomandibular joint (TMJ).
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.

| Measure | Description | Time Frame |

| Pain decrease | 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. | baseline (preop), 1 week, 1 month, 2 months, 6 months, 12 months (postop) |
| increase in the mouth opening | 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 | Baseline (preop), 1 week, 1 month, 2 months, 6 months, 12 months (postop) |
| TMJ click and noises reduction | At the end of 1 year, (75%) patients stated no evidence of clicking. | Baseline (preop), 12 months (postop) |
| Measure | Description | Time Frame |
|---|---|---|
| number of subjects showing signs of TMJ inflammation or structural alterations at Magnetic Resonance Imaging and Cone Beam Computerized Tomography pre- and postop. | 40% of subjects who showed clear signs of inflammation showed significant improvement, in 30% with structural alterations was evident the absence of intra-articular adhesions and debris, in 30% with internal derangement did not appear any radiographic change. |
