Plain English summary of protocol
Background and study aims
Today, guided procedures are popular because they increase the predictability and the safety of the treatment provided to patients. Guidance with ultrasound imaging is a safe procedure without any side effects. This study aims to obtain more accurate injections and follow up the results after the injections, and investigate the role of the guidance in reducing the symptoms associated with temporomandibular joint disorders (a condition affecting the movement of the jaw).
Who can participate?
Patients aged 18-60 years with temporomandibular joint disorders
What does the study involve?
Platelet-rich plasma (PRP) was injected with a contrast medium and the mixture was delivered into the upper joint space through reference points drawn on the face (non-guided method) in 12 patients, while the mixture was delivered into the upper joint space in the remaining 12 patients using ultrasound guidance followed by a CBCT scan to determine the location of the mixture in the tissues, and then the patients were followed up several times for 3 months after the injection. The following were measured: the duration of the session, the number of re-injections, and the number of redirections. Pain at rest and function were also recorded in the first 3 days after the injection, and the maximum mouth opening, joint sounds, and pain when palpating the joint were followed up 1 week, 1 month and 3 months after the injection.
What are the possible benefits and risks of participating?
The study does not involve any risks as the PRP is taken from the patient and the contrast media is tested before it is delivered to the joint tissues.

| Secondary study design | Randomised controlled trial |
| Study type | Participant information sheet |
| Scientific title | A randomized clinical study of the accuracy of intra-temporomandibular joint injections combining non-guided injection with ultrasound-guided injection, with a comparison of the procedure and therapeutic efficacy |
| Study objectives | Does ultrasound guidance help to obtain more accurate, easier, and more efficient injections in treating symptoms associated with temporomandibular joint disorders compared to the non-guided method? |
| Ethics approval(s) |
Approved 30/08/2021, Damascus University (Damascus, Damascus, -, Syria; +963 (0)1133923192; ap.srd@damascusuniverity.edu.sy), ref: 231-290424-DN |
| Health condition(s) or problem(s) studied | Temporomandibular joint disorders |
| Intervention | Participants were randomly allocated by drawing cards to non-guided injection or ultrasound-guided injection. Platelet-rich plasma (PRP) was injected with contrast medium Ominpque 350 mg and the mixture was delivered to the joint through reference to points drawn on the face in 12 patients. While the mixture was delivered to the remaining 12 patients using ultrasound guidance, this was followed by a CBCT scan to determine the location of the mixture in the tissues, and then the patients were followed up several times for 3 months after the injection. |
| Intervention type | Procedure/Surgery |
| Primary outcome measure(s) |
1. Accuracy of the injected mixture location measured using CBCT imaging just after the mixture is delivered |
| Key secondary outcome measure(s) |
Optimal PRP and iodinated contrast agent mixture ratio for TMJ CBCT arthrography, determined using CBCT imaging and questionnaire (this part of the study was done before the main part that involved 24 samples, aiming to find the appropriate mixture for use in the primary objectives of the study) |
| Completion date | 30/04/2024 |
