About this study

Official title: The Evaluation Of The Efficacy Of Auriculotemporal Nerve Block In Temporomandibular Disorders

The retrospective study aimed to evaluate the efficacy of the Auriculotemporal Nerve Block (ATNB) in achieving unrestricted mouth opening amount and in reducing the pain scores in those patients diagnosed with disc displacement with (DDWR) and without reduction (DDWOR) according to the Diagnostic Criteria for Temporomandibular Disorders, who could not benefit from noninvasive methods but did not want further invasion.

Read the detailed description

The records of 410 patients referred to the Department of Oral and Maxillofacial Surgery with TMD symptoms were reviewed to determine the treatment modalities used and their outcomes. The subjects were examined and diagnosed according to the Turkish translation version of The Diagnostic Criteria for Temporomandibular Disorders (DC/TMD-Axis 1 questionnaire and examination form). The pain intensity, maximal mouth opening (MMO) amounts, and self-reported outcome variables of twenty-two patients who underwent non-invasive therapies (occlusal stabilization splints, behavioral modifications, physical therapy, pharmacotherapy) but did not benefit from them and volunteered for the ATNB instead of invasive therapies (arthrocentesis, arthroscopy, and discectomy) were also evaluated. Prior to the ATNB, written informed consent was obtained from each participant. Also, each participant was warned about complications of the ATNB before the administration, such as hematoma at the injection site, positive aspiration, and temporary anesthesia of the facial nerve.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • local anaesthetic injectionProcedure or surgery

    The head and neck of the condyle were detected by palpating the pretragal area. Then, the needle was inserted anterior to the junction of the tragus and the lobule. After 0.5 ml the solution was subcutaneously infiltrated, the needle was protruded until it touched the neck of the condyle. Aspiration was performed to avoid intravenous injections, and the remaining solution was injected thereafter.

Study groups in NCT04827784
Study groupRoleWhat they receive
Auriculotemporal Nerve Block AdministrationExperimentalA total of 3 doses of Auriculotemporal Nerve Block (ATNB) were administered to involved participants. Local anesthetic solutions containing Articaine Hydrochloride (80 mg / 2 ml) and epinephrine bitartrate (0.02 mg / 2 ml) were used for ATNB application. The injections were repeated on follow-up visits in the first and fourth weeks. The maximal mouth opening amounts, pain intensity values (via VAS scale), and self-reported outcomes were evaluated at the pre-injection, first week, fourth week, and sixth-month follow-up controls.
Receives: Procedure: local anaesthetic injection

What is being measured

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

  1. Baseline Pain Intensity

    Pain intensity was measured using a 10-point Visual Analog Scale (VAS), in which 0 referred to 'no pain', 5 referred to 'moderate pain,' and 10 referred to 'excruciating pain'. The patients were asked to mark their pain intensities on VAS scale.

    Measured: At the initial visit before starting anesthetic administration.

  2. Post-injection Pain Intensity

    Pain intensity was measured using a 10-point Visual Analog Scale (VAS), in which 0 referred to 'no pain', 5 referred to 'moderate pain,' and 10 referred to 'excruciating pain'. The patients were asked to mark their pain intensities on VAS scale.

    Measured: At six months follow-up visit

  3. Change From Baseline Maximal Mouth Opening on Post-Injection Follow Up Visits

    All patients' maximal mouth opening were measured and recorded as the distance between upper and lower right central incisors.

    Measured: At the first week, fourth week and sixth month.

Secondary outcomes (1)
  1. Overall Satisfaction With The Applied Treatment

    Patients were asked dichotomously to define the ATNB as successful/unsuccessful, according to their experience. The patients' responses were recorded individually.

    Measured: At the six-month follow-up visit

Questions about this trial

What is this clinical trial studying?

A study testing local anaesthetic injection in people with Temporomandibular Joint Disorders and Arthralgia of TMJ, run by Tokat Gaziosmanpasa University at 1 site in Turkey (Türkiye).

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 1 inclusion and 5 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 1 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Baseline Pain Intensity (time frame: At the initial visit before starting anesthetic administration.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04827784, which also lists 3 linked publications.

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 1 Apr 2021.
