Sustained and Repeated Mouth Opening Leads to Development of Painful Temporomandibular Disorders Involving Macrophage/Microglia Activation in Mice

Temporomandibular disorder (TMD) is a set of heterogeneous musculoskeletal conditions involving the temporomandibular joint (TMJ) and/or the masticatory muscles. Up to 33% of the population has had at least one symptom of TMD with 5-10% of them requiring treatment. Common symptoms include limited jaw movement, joint sound, and pain in the orofacial area. Once TMD becomes chronic, it can be debilitating with comorbidities that greatly reduce one's overall quality of life. However, the underlying mechanism of TMD is unclear due to the multicausative nature of the disease.

Prevalence of TMD in Sjӧgren Syndrome Patients

Sjӧgren's Syndrome seems to play a role in temporomandibular joint disorders.

Early Molecular Response and Microanatomical Changes in the Masseter Muscle and Mandibular Head After Botulinum Toxin Intervention in Adult Mice

The Botox-injected masseters had greatly increased expression of genes involved in muscle atrophy at the 1 week time point compared to the control side muscles. At the end of the study, 2 weeks after injection, the Botox-injected masseters were about 20% smaller than the control side masseters, and the Botox-side condyles had lost about 40% of relative bone area compared to the control side condyles.

Centralized Pain in TMD: Is It All in the Head?

We are pleased to introduce Sophia Stone, a new contributor to The TMJ Association, whose passion is to separate TMD fact from TMD fiction. Sophia has a background in medicine and research and can draw on her personal experience as a TMD patient.

I am 53 years old and have had five jaw surgeries. In the first surgery my lower jaw was lengthened. The second surgery bone spurs were removed and the discs were pulled back into place. For the third surgery in 1994, I had artificial joints by TMJ Implants, Inc. The fourth surgery was in August 2012 to remove the worn out joints and insert spacers.  The surgery was very lengthy--over 8 hours. Scar tissue that had formed was removed. One side was out of the hinge and the other side had screws floating in scar tissue. My jaw was wired shut for the first night; images were obtained and sent to the implant manufacturer. After the surgery I had swelling, pain, and facial paralysis. I had minimal movement of my upper lip, nose, and eyebrows. My fifth surgery was in October 2012 for which I received custom joints by TMJ Concepts.  Even though some modifications were necessary to make one of the joints fit, the surgery went very well and I had very little swelling. After a pain protocol was established, I was able to control the pain and chew soft foods.

Now I am three years post op, and I still have side effects from the surgeries. My eyebrows still do not move. I have some swelling in my cheeks and numbness on the right side. In January of 2016 I will have an eyebrow lift. I am also experiencing a hooding effect, which affects my vision. This picture was taken in August of 2015. I'm progressing, but not as quickly as I would like.
