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

Condition or disease Intervention/treatment
TMJ Internal Derangement Procedure: TMJ arthrocentesis

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.

Group/Cohort Intervention/treatment
arthrocentesis in TMJ internal derangement
30 patients with TMJ internal derangement and pain with history of failed conservative management.
Procedure: TMJ arthrocentesis
lavage of the superior TMJ space with saline and sodium hyaluronate (SH)

Primary Outcome Measures :
  1. 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.

  2. 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

  3. 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 Outcome Measures :
  1. number of subjects showing signs of TMJ inflammation or structural alterations at Magnetic Resonance Imaging and Cone Beam Computerized Tomography pre- and postop. [ Time Frame: Baseline (preop)- 60 days 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.

Sampling Method:   Non-Probability Sample
Study Population
A total of 30 patients with TMJ internal derangement and pain with history of failed conservative management were selected. 70% had anteriorly displaced discs (AD), and 30 complained of other disorders (osteophytes, signs of soft tissues inflammmation, TMJ structure alterations).

Inclusion Criteria:

  • TMJ pain
  • 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
