Effects of the Bilateral Mandibular Nerve Block (V3) in Mandibular Osteotomy

April 13, 2022 updated by: University Hospital, Montpellier

Effects of the Bilateral Mandibular Nerve Block (V3) in Mandibular Osteotomy: a Prospective, Randomized, Double-blind Versus Placebo Study

The sensory innervation of the face depends on the trigeminal (fifth cranial) which is divided into three branches, the mandibular nerve (V3) having motor fibers to the temporal and masseter muscle. The regional anesthesia of the face has grown in recent years for performing certain actions under light general anesthesia or sedation. The mandibular block is a simple and reliable technique but little used. Yet it reduces postoperative pain sagittal osteotomy of the mandibular branch by reducing consumption of opioids and in the oropharynx cancer surgery. Made with ropivacaine, known for its vasoconstrictive action, it also improves the visibility of the operative field during mandibular osteotomies reducing bleeding. Despite a real clinical benefit (ease of implementation, latency and duration of action of the local anesthetic), the V3 block ropivacaine is not evaluated in the maxillofacial surgery.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
consumption of morphine (cumulative dose) during the first post operative 24 hours valued in mg
Time Frame: 1 day
1 day
consumption of morphine (cumulative dose) during the first post operative 24 hours detected thanks to the "Patient Controlled Analgesia"
Time Frame: 1 day
1 day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Tolerability : effects of the block on nausea / vomiting (consumption of antiemetic in mg) during the first post operative 24 hours
Time Frame: 1 day
1 day
Postoperative pain valued thanks to Visual Analog Scale (VAS), VAS max in post anesthesia care units (PACU) every 30 minutes and in department every 4 hours
Time Frame: 1 day
1 day
postoperative bleeding (in mL)
Time Frame: 1 day
1 day
