Presentation
In some patients the R1 component was also present on the side contralateral to the stimulus, while in normal subjects it was present only on the ipsilateral side. [ncbi.nlm.nih.gov]
2014 Articles Background: We present the case of a 65-year-old female with sudden-onset involuntary mouth opening, deviation of the jaw, facial grimacing, and tongue movements that started 6 months prior to her admission. [academiccommons.columbia.edu]
Jaw & Teeth
- Oral Ulcers
The therapeutic approach adopted to reduce the severe oromandibular movements, dysphagia, and the numerous oral ulcers was selective electromyography (EMG)-guided botulinum toxin application to the inferior head of the lateral pterygoid muscles and masseters [ncbi.nlm.nih.gov]
- Numbness of the Tongue
A 56 year-old female patient presented at the emergency department after ten days of chemotherapy with progressive airway obstruction and complaints of numbness of the tongue. She also had difficulty swallowing and was unable to speak. [ncbi.nlm.nih.gov]
Psychiatrical
- Loss of Initiative
Significant weight loss was reported in 3 out of 5 patients with eating dysfunction and OMD. Only patients with both OMD and OBL dyskinesias experienced weight loss. The weight loss ranged from 13–15 lbs (13.6% to 10.5% loss of initial body weight). [head-face-med.biomedcentral.com]

- Postural Instability
Dystonia is defined as muscle spasm resulting in abnormal posturing of the anatomical regions involved. Parkinsonism is defined when there are two or more of the following features: tremor, bradykinesia, rigidity and postural instability. [jnnp.bmj.com]
Dystonia follows Parkinson's disease (a neurological movement disorder associated with bradykinesia, tremor, rigidity, and postural instability) and essential tremor (a common movement disorder characterized by involuntary, rhythmic oscillatory movements [sites.google.com]
- Rubral Tremor
Patient distribution was as follows: Seven patients had chorea due to HD, 1 had tardive dystonia, 1 had oromandibular dystonia (OMD), 1 had post-ischemic hemidystonia, 1 had hemiballismus, and 1 patient had post-traumatic rubral tremor. dagger]) EPS [medical-dictionary.thefreedictionary.com]
Workup
Workup Patients should be evaluated for a family history of dystonia or the presence of other dystonias. [entokey.com]
Urine
- Acanthocytes
Routine blood tests, as well as tests for serum copper, ceruloplasmin, and acanthocytes, yielded normal results. Video-EEG monitoring did not detect abnormalities. [elsevier.es]
Treatment
After BoNT treatment, there was a significant reduction in the mean total OMDQ-25 score at 4 weeks (38.2 ± 17.6; p = 0.004), as well as at 8 weeks (39.6 ± 18.1; p = 0.008). [ncbi.nlm.nih.gov]
Oral agents remain one of the first-line medical treatments for OMD, and evaluation by a neurologist for consideration of such treatment is a prudent initial step. [entokey.com]

For example, patients with less than a 50% improvement on a 1 to 100 function rating scale were re-injected less than a month following their initial treatment. The overall median time between treatments was 3 months. [mdedge.com]
Prognosis
The prognosis is poor and the treatment is symptomatic. This paper describes a case of a 38-year-old woman referred for a locked left TMJ who was diagnosed as having an oromandibular dystonia. [ncbi.nlm.nih.gov]

Types of dystonia: The many types of dystonia are divided into separate groups because of their implications for treatment and prognosis. [hopkinsmedicine.org]
Prognosis What is my prognosis? If dystonia develops in childhood, particularly if it starts in the legs, then in many (but not all) cases it will spread to other parts of the body and become generalised. [brainfoundation.org.au]
Etiology
Clinical characteristics, etiology of brain injury, and pattern of dystonia were analyzed. Patients with clinically significant CD and OMD were treated with BTx and followed for 12 weeks. [ncbi.nlm.nih.gov]
By definition, all cases of "dystonia plus" are secondary, although the etiology (eg, neuroleptics, Wilson disease, neuroacanthocytosis, trauma) may not always be obvious. [medlink.com]
Differential diagnosis of oromandibular dystonia and various etiologies were investigated. Neuroimaging studies revealed a left cerebellar infarction. [academiccommons.columbia.edu]
The etiology is unknown but in the idiopathic form is believed to be related to a neurotransmitter defect possible in the basal ganglia. About 20% of patients with brain injuries develop new onset cervical or oromandibular dystonias. [mussenhealth.us]
Epidemiology
These results may be of value with regard to the conduct of multicenter epidemiologic and clinical studies on focal dystonias. [ncbi.nlm.nih.gov]
Epidemiology, clinical features, and etiology Oromandibular dystonia affects women more frequently than men and the prevalence was estimated to be 68.9 cases per 1 million Americans (for reviews see Bhidayasiri et al. [2006]). [cambridge.org]

The effect of cholinergic agents was less than the effect of dopaminergic drugs, implying that dopamine plays a predominant role in the pathophysiology. [ncbi.nlm.nih.gov]

Prevention
In the present case history, treatment for OMD was started as soon as the diagnosis of jaw-closing OMD was established, and dental treatment intervention for preventing its development or progression was considered at the same time. [ncbi.nlm.nih.gov]
It prevents specific neurotransmitters from reaching the affected muscles, preventing spasms. Botulinum toxin is administered by injection. One dose usually lasts about 3 months. There may be some initial (temporary) pain at the injection site. [medicalnewstoday.com]
Therefore, to prevent these and other complications, prompt and appropriate treatment of OMD is important. [doi.org]
