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]
Some patients presenting OMD subsequent to focal radiotherapy may have a genetic susceptibility, given that many more patients do not; this topic requires further clarification. [elsevier.es]

- Yawning
Sometimes, the condition may be partially relieved by humming, singing, yawning, deliberately moving the mouth or by touching the chin and lips. Though oromandibular dystonia progresses in this way, it is not life threatening. [acaciadermacare.com]
Many patients had discovered tricks to open the eyes, including forced jaw opening, yawning, neck extension, or prising thern open with the fingers. Many developed a secondary blepharitis due to the spasms. [baillement.com]
Overactive movement of the muscles of the larynx (excessive closure or opening of the vocal cords) occurs during specific vocal activities such as speaking but not during laughing or yawning. [brainfoundation.org.au]
Improved speech is noted during emotional or physiological states for example joy, anger or following yawning. Shouting or stress usually makes the condition worse. Treatment can be difficult and is dependent on the individual. [netdoctor.co.uk]
- Hoarseness
The patient may sound hoarse, breathless, anxious or groaning. In the abductor type, there is an overcontraction of the muscles that separate the vocal cords, resulting in a choppy and breathy whispering voice pattern. [netdoctor.co.uk]
Eyes
- Blepharospasm
These results indicate that the neuronal arcs of the facial reflexes in blepharospasm and oromandibular dystonia are normal. [ncbi.nlm.nih.gov]

BACKGROUND: Oromandibular dystonia is a movement disorder that is characterized by involuntary masticatory and/or lingual muscle contracture. [ncbi.nlm.nih.gov]
For instance, dystonic contracture of the masticatory muscles can expand to the orbicularis oris muscle, orbicularis oculi muscle, neck and shoulder muscles. [sites.google.com]

OBJECTIVE: Most patients with tardive dystonia have a focal onset involving the cranial-cervical region. Because of its resemblance to idiopathic cranial dystonia, a common form of dystonia, it often poses a diagnostic problem. [ncbi.nlm.nih.gov]
One patient (6) had pre-existing cervical dystonia and had received haloperidol as a treatment for her cervical dystonia. [dx.doi.org]
- Involuntary Movements
Oromandibular dystonia (OMD) is defined as a subset of movement disorders characterized by involuntary muscle contraction in different parts of the oromandibular region. [ncbi.nlm.nih.gov]
Case 5 A 56-year-old female presented with a chief complaint of involuntary jaw movements. [head-face-med.biomedcentral.com]
Abnormal fluency or speed of movement might manifest as excessive or involuntary movement, or slow or absent voluntary movement. [sites.google.com]
Jaw Closing Involuntary actions of the masseter, temporalis, and internal or medial pterygoid muscles are responsible for jaw-closing OMD movements ( Fig. 5.3 ). [entokey.com]
- Slurred Speech
Side effects of this treatment may include difficulty swallowing, slurred speech and weakness, but they are short-term and well-tolerated. [ic.steadyhealth.com]
Side effects such as swallowing difficulties, slurred speech, and excess weakness in injected muscles may occur, but these side effects are usually transient and well tolerated. [dystonia-foundation.org]
- Tremulousness
DISCUSSION In the classical description of Samuel Kinnier Wilson on the progressive lenticular degeneration, different phenotypes were described, such as the dystonic (including a tremulous form) and Parkinsonian forms 11. [scielo.br]
Dsytonic movements are typically patterned, twisting and may be tremulous. Dystonia is often initiated or worsened by voluntary action and associated with muscle overflow activity. [cmdg.org]
Dystonic movements are typically patterned, twisting, and may be tremulous. Dystonia is often initiated or worsened by voluntary action and associated with overflow muscle activation [ 3 ]. [intechopen.com]
Sufferers find that their voice sounds strained and strangled, that it takes a lot of effort to speak and that their voice comes out as tremulous, weak or a breathless whisper. There are two types of spasmodic dysphonia. [netdoctor.co.uk]
- Abnormal Involuntary Movement
Description Dystonia is a neurological movement disorder that causes muscles in the body to contract or spasm involuntarily. The involuntary muscle contractions cause twisting, repetitive and patterned movements as well as abnormal postures. [brainfoundation.org.au]
Workup
Workup Patients should be evaluated for a family history of dystonia or the presence of other dystonias. [entokey.com]
Treatment
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]
Botulinum type A toxin is an effective treatment of oromandibular dystonia. It is important for clinicians to recognise the condition, as treatment is well-tolerated and can improve quality of life. [ncbi.nlm.nih.gov]
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]

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. [dx.doi.org]
