OBJECTIVE
Motor control of the muscles of the face, lips, and tongue of horn players has traditionally been described from externally observed phenomena. Developments in real-time, high-speed magnetic resonance imaging (MRI) extend the scope of study to include descriptive and quantitative
OBJECTIVE
The inability to propel a bolus of food successfully from the posterior part of the oral cavity to the oropharynx is defined as transfer dysphagia. The present case series describes the varied presentation of transfer dysphagia due to focal dystonia and highlights the importance of early
Oromandibular dystonia consists of prolonged spasms of contraction of the muscles of the mouth and jaw. Primary idiopathic forms and secondary forms exist. Secondary dystonia develops due to environmental factors; some cases of cranial dystonia after dental procedure have been reported, but the
BACKGROUND
This paper describes the use of real-time magnetic resonance imaging in visualizing and quantifying oral cavity motor strategies employed by 6 healthy, elite horn players and 5 horn players with embouchure dystonia.
METHODS
Serial images with an acquisition time of 33.3 ms were obtained
Dystonia is a neurological disorder that can cause constant muscle contractions and motor limitations. This work reports a clinical case of periodontal treatment in a patient with generalized idiopathic dystonia. The intraoral clinical examination was focused on the presence of caries and
The embouchure of trumpet players is of utmost importance for tone production and quality of playing. It requires skilled coordination of lips, facial muscles, tongue, oral cavity, larynx and breathing and has to be maintained by steady practice. In rare cases, embouchure dystonia
OBJECTIVE
To investigate the prevalence of substance abuse (SA) in patients with cervical dystonia (CD) and to correlate it with prevalence of psychiatric disorders.
METHODS
Data on anxiety, depression, dystonia severity, and substance abuse were collected from ten sites participating in the
Dermoid cysts are rare masses of the oral cavity derived from ectodermal elements. These are benign, slow-growing tumors that are typically asymptomatic but cause complications of inflammation or dysphagia, dystonia, and airway encroachment due to mass effects. We report the case of a 17 year old
Giant perivascular spaces (PVS) are rare, CSF-filled, dilated cavities lined by the pia mater that are most often asymptomatic radiological findings but can sometimes cause neurological symptoms. We present two exceptional cases of secondary focal dystonia induced by the mass effect on the basal
Oromandibular dystonia is characterized by persistent contractions and repetitive spasms of masticatory muscles surrounding the oral cavity and lingual muscles. The lingual dystonia is rare hyperkinetic movement disorder, often occurring secondary to drugs. The common drugs which can cause acute
Recently, patients receiving the long-term administration of typical antipsychotics have been recognized to be at risk of developing intractable tardive dystonia. A 44-year-old man was referred to our hospital because of progressive dysphagia for about 5 years. He had received several typical
This paper describes the use of real-time MRI at 30 frames/s in studying motor function within the oropharyngeal cavity of a trumpet, horn, trombone, and tuba player. Using Image J and customized MB-Ruler Pro software, analyses of discrete 33.3 ms snapshots of motion extracted from real-time MRI
Neuroferritinopathy is an autosomal dominant basal ganglia disease with iron accumulation caused by a mutation of the gene encoding ferritin light polypeptide (FTL). Six pathogenic mutations in the FTL gene have so far been reported. One such mutation was found in a Japanese family, thus suggesting
We assessed the oropharyngeal swallowing ability in 8 patients with Parkinson's disease (PD), 8 patients with progressive supranuclear palsy (PSP), and 10 age-matched healthy controls (CTL) using videofluorography (VF). In VF studies, PD and PSP patients demonstrated food pooling on the tongue,
Polysystemic autoimmune diseases often cause orofacial and stomatognathic symptoms. Inflammation of the temporomandibular joint only rarely and slightly reduces the range of mouth opening (rheumatoid arthritis), which is much more restricted in systemic sclerosis due to fibrosis of perioral soft
