Study summary

The aim of this study is To compare the accuracy and effectiveness of ultrasound (US) guided autologous blood injection (ABI) versus non- guided technique for the treatment of chronic recurrent temporomandibular joint dislocation

Read the detailed description

All patients involved in this study will be divided randomly to two different groups and injected with autologous blood into joint space and pericapsular tissue.

Study group (group A) will be injected with autologous blood with ultrasound guidance.

control group (group B) will be injected with autologous blood without US guidance. Anatomical landmarks and tactical sense will be followed only.

The operation will be done under local anesthesia ( Auriculotemporal nerve block ) the skin overlying the temporomandibular joint will be scrubbed by an antiseptic solution and the area will be isolated with sterile towels. External auditory canal will be blocked with cotton.

About 3 ml of blood will be withdrawn from patient's antecubital fossa, of which 2 ml injected intra-articular and 1 ml in the pericapsular tissue (PT) The procedure should be repeated on the opposite side in case of bilateral involvement.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. maximum mouth opening

    change in Maximum mouth opening (MMO): It's measured (in millimeter) from incisal edge of 11 to 41, in maximum mouth open position using caliper

    Time frame: at 2weeks, 3months and 6 months post-operative

Secondary outcomes

  1. Frequency of temporomandibular joint dislocation:

    number of dislocation per week

    Time frame: 2weeks, 3 months and 6 months post-operatively

  2. change of pain

    measuring pain using visual analogue scale(0-10),higher scores mean worse outcome.

    Time frame: 2weeks, 3 months and 6 months post-operatively

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jan 2024 (actual). Primary completion is estimated for Jul 2024, 6 months after the start.

Of 24 interventional studies with no phase under Joint Dislocations, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 68. This study's planned 6 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 6, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
