Botox for Treatment of TMJ Disorder With Bruxism (TMJ)

January 21, 2018 updated by: Ethan Baughman, Washington University School of Medicine

Phase 1 Study of Role of Botox in Myofascial Temporomandibular Disorder

Hypothesis: Myofascial temporomandibular joint disorder and related symptoms are associated with mandibular condyle and temporal fossa overloading secondary to temporalis and masseter muscle hyperactivity and spasm

This study will examine the use of onabotulinumtoxinA (Botox) to treat myofascial pain disorder in patients with bruxism who frequently exhibit signs of temporomandibular joint disorder (TMD) in a double blind cross-over randomized clinical trial by injecting 50 units Botox in temporalis and masseter muscles in 32 patients with 6 months follow up.

The objective of the proposed study will be to establish the safety and efficacy of botox in treating TMD associated with bruxism. By the time patients reach the specialists office, most have failed maximal conservative therapies, including non-chew diet, night guard, oral analgesics, muscle relaxants, physical therapy, and a portion have even undergone more invasive procedures, such as manipulation under anesthesia, arthroscopy, and arthroplasty surgeries with limited improvement or recurrence. Primary outcome of the study will be 50% reduction in pain. Secondary outcomes will be 50% reduction in surgical therapy, 25% increase in maximal inter-incisal opening (MIO). The investigators look forward to working with you on the proposed study

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.

Detailed Description

The study will enroll 32 patients with myofascial TMD. Patient will be aged 18-65. Exclusion criteria will include neuromuscular diseases, prior botox injections within previous 12 months, pregnancy, and fibromyalgia. All patients will be selected from the outpatient clinic, complaining of TMJ disease associated with bruxism. Screening will include a thorough history and exam, and TMJ CT scan or MRI. Patients with neuromuscular disorders, musculoskeletal disorders, and prior Botox injections will be excluded. Patients who have not already undergone conservative treatment will be managed with 3 months conservative therapies prior to becoming eligible. All patients will be informed and consented for participation in the study and Botox injections. Baseline pain questionnaire, physical exam will be performed. Patients will be randomized to receive normal saline or botox injections. All patients will crossover for the second set of injections at 3 months. All patients will receive up to a total of 200 Botox units at either 0 or 3 month time points. In this regard, patients will act as their own placebo control. Botox will be prepared according to the manufacturer's instructions. Briefly, the lyophilized protein will be reconstituted with preservative-free normal saline and drawn into 1-mL syringe. While the patient is sitting in the office procedure chair, 25 to 50 U of Botox will be injected into each temporalis muscle and 25 to 50 U of Botox will be injected into the each masseter muscle. The patient will be instructed to keep head elevated for 8 hours. Patients will be called 3 times after the first round of injections, to monitor for adverse events. Patients will be seen in clinic at 3 months and asked to fill out a second pain questionnaire. They will also undergo second physical exam, and then receive a second set of injections (crossover). Patients will be seen in clinic at 6 months and asked to fill out a third pain questionnaire undergo third physical exam. Patients will be called 3 times after the second round of injections, to monitor for adverse events. Patients will be seen in clinic at 6 months and asked to fill out a third pain questionnaire undergo a third physical exam

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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

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.
