About this study

Temporomandibular joint (TMJ) arthroscopy has been used successfully for intra-articular disorders. Until now, limited studies are available regarding the clinical evidence of bilateral TMJ arthroscopy for Dimitroulis 2-3. This prospective study investigated the efficacy of TMJ arthroscopy in patients with bilateral disorders, and also the need for a posterior surgery.

Read the detailed description

Temporomandibular joint (TMJ) arthroscopy has been used successfully for intra-articular disorders. It was first introduced by Onishi at 1975, as a pioneering technique to treat painful joints and has been associated with a reduction in the number of open joints surgeries. This minimally invasive technique allows observation of the TMJ upper compartment tissues, and sometimes the lower compartment. Moreover, this intervention allows joint lysis and lavage (level 1 arthroscopy) and intra-articular surgical procedures (level 2-3 arthroscopy).

Recent studies updated that TMJ arthroscopy promotes a reduction in pain and inflammatory process and restoring the mandibular function with low morbidity. Moreover, TMJ arthroscopy seems to be also long-term effective for relieving TMJ symptoms. Until now, limited studies are available regarding the clinical evidence of bilateral TMJ arthroscopy for Dimitroulis 2-3. This prospective study investigated the efficacy of TMJ arthroscopy in patients with bilateral disorders, and also the need for a posterior surgery.

What participants receive

  • bilateral temporomandibular joint arthroscopyProcedure or surgery

    The TMJ arthroscopy was performed with a 1.9-mm arthroscope including a video system, with a 2.8-mm outer protective cannula. Briefly, for TMJ arthroscopy level 1, the authors used the classic puncture with an entry point 10 mm anterior and 2 mm below the Holmlund-Hellsing (H-H) line. A second puncture with a 21-G needle was performed 30 mm anterior and 7 mm below the H-H line to wash the joint with 250-300 ml Ringer solution. After washing the joint, 1.5-2 cc of hyaluronic acid was injected into it. For level 2 TMJ arthroscopy, the second puncture was substituted by a 2.8-mm outer protective cannula with a sharp trocar until the joint was reached. The 2.8-mm cannula was used for (1) intra-articular coblation and/or (2) intrasynovial medication. Antibiotic and non-steroidal anti-inflammatory drugs were routinely prescribed. Patients were instructed to follow a soft diet for 3 days after surgery and 5 physiotherapy and 3 speech therapy exercise sessions after intervention.

  • Xeomin® (Merz)Drug

    For tenderness grade 2, 155U of Incobotulinum toxin A was injected in the masticatory muscles and for tenderness grade 3 195U of Incobotulinum toxin A was injected. The authors used Xeomin® (Merz) in all patients.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pain (Visual Analogue Scale (0,10)

    VAS, 0-10, with 0 being no pain and 10 having maximum unbearable pain

    Measured: Pre-surgery

  2. Pain (Visual Analogue Scale (0,10)

    VAS, 0-10, with 0 being no pain and 10 having maximum unbearable pain

    Measured: Through study completion, an average of 2.5 years

Secondary outcomes (4)
  1. Maximum mouth opening (MMO, mm)

    Mouth opening measured with a ruler (mm)

    Measured: Pre-surgery

  2. Maximum mouth opening (MMO, mm)

    Mouth opening measured with a ruler (mm)

    Measured: Through study completion, an average of 2.5 years

  3. Muscle tenderness (0-3 scale)

    0-3, corresponding to a muscle tenderness scale in masseter and temporalis muscle (0-whithout muscle tenderness, 3 - maximum muscle tenderness)

    Measured: Pre-surgery

  4. Muscle tenderness (0-3 scale)

    0-3, corresponding to a muscle tenderness scale in masseter and temporalis muscle (0-whithout muscle tenderness, 3 - maximum muscle tenderness)

    Measured: Through study completion, an average of 2.5 years

Questions about this trial

What is this clinical trial studying?

A study testing bilateral temporomandibular joint arthroscopy and Xeomin® (Merz) in people with Bilateral Temporomandibular Joint Disorder, run by Instituto Portugues da Face.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain (Visual Analogue Scale (0,10) (time frame: Pre-surgery). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Sep 2021.
