Objective: To clarify the pathophysiology of dysphagia by electrophysiological methods. Method: Electrophysiological methods related to oropharyngeal swallowing were used to investigate 25 patients with cervical dystonia and 25 age matched normal volunteers. Results: Dysphagia was suspected in 36% of patients with cervical dystonia on the basis of clinical assessment. The incidence of dysphagia increased to 72% on electrophysiological evaluation of pharyngeal swallowing. Submental muscle electromyographic (EMG) and laryngeal relocation times were significantly prolonged and the triggering time to swallowing reflex was significantly delayed. Some abnormalities seen in cricopharyngeal sphincter muscle EMG indicated that the striated sphincter muscle is hyperreflexive in some patients. Conclusion: Neurogenic dysphagia was more prominent and longer lasting than mechanical dysphagia, which was transient and varied from patient to patient. Although these electrophysiological methods were not suitable for detecting anatomical changes during swallowing, as in videofluoroscopic studies, observations supported the neurogenic cause of dysphagia in patients with any kind of cervical dystonia.

“…Oropharyngeal function is usually investigated with the aid of videofluoroscopy. Clinical and videofluoroscopic evaluations have also indicated a high incidence of swallowing disorders in patients with CD before any treatment such as BoNT injection or rhizotomy [7][8][9]. In one study, swallowing abnormalities during video fluoroscopic examination were observed in over 50 % of CD patients [7].…”

“…Dysphagia and dysarthria (which account for 10.2 % to 37 % and 0.9 % of complaints, respectively) are the two most common adverse effects of BoNT treatment for OMD [37,42]. Clinical and videofluoroscopic evaluations have also indicated a high incidence of swallowing disorders in CD patients before any treatment such as BoNT injection or rhizotomy [7][8][9]. In a study by Comella et al, although new radiologic changes occurred in 50 % of CD patients following BoNT treatment, clinically only 33 % of these patients reported new dysphagia symptoms.…”

“…Various studies have shown that before treatment is started, some focal craniocervical dystonias such as spasmodic dysphonia and CD can be accompanied by a range of swallowing difficulties [6][7][8][9][10][11][12][13][14][15]. The incidence of dysphagia varies between 22 and 100 % of CD patients and is usually over 50 %.…”

“…It increases significantly after botulinum toxin (BoNT) injection [8,11,12]. Dysphagia is suspected in 36 % of patients with CD on the basis of clinical assessment, and the incidence increases to 72 % on electrophysiological evaluation of oropharyngeal swallowing and after selective rhizotomy [8,9]. Similarly, dysphagia in patients with spasmodic dysphonia has been reported before and after treatment of this condition [13][14][15].…”

Blepharospasm "lepharospasm "SP is a form of focal dystonia characterized clinically by involuntary periocular spasms resulting in forceful eye closure [ , , ]. "SP is characterized by tonic, phasic or combined involuntary tonic-phasic contractions of the orbicularis oculi muscles, producing repeated and frequent blinking and persistent forceful closure of the eyelids with various degrees of functional blindness. The characteristic features of "SP include sensory tricks that patients use to relieve their symptoms geste antagoniste and a high frequency of ocular symptoms starting before or at the onset of the spasm [ , , ]. "SP may be associated with inhibition of the levator palpebrae muscle apraxia of eyelid opening or involuntary movements in the lower face or jaw muscles [ , , ]. "praxia of eyelid opening may in turn be associated with other neurological conditions, such as progressive supranuclear palsy and corticobasal degeneration [ , ]. . .

Lingual dystoniaDystonic involvement of the tongue is a well-recognized feature of tardive dystonia as well as OMD, both primary and secondary, although primary focal lingual dystonia PFLD has only rarely been described. PFLD presents as an action dystonia during speech or in paroxysmal episodic lingual dystonic spasms [ ]. " rare disorder, it can be severe enough to affect speech, swallowing and breathing. Tardive lingual dystonia secondary to dopamine-receptorblocking drugs may manifest as a relatively isolated problem. "lthough severe tongue protrusion, particularly during eating, is characteristic of neuroacanthocytosis, it can also be . Treatment of craniocervical dystonias with BoNTWhile "oNT treatment remains the treatment of preference for most focal dystonias, pharmacological and neurosurgical treatments are also important in the treatment algorithm. Treatment with "oNT in properly adjusted doses is known to be effective and safe for cranial and cervical dystonia, but not OMD. In recent years, long-term studies on the efficacy and safety of "oNT-" have been published, a new "oNT-" formulation has been marketed and new studies on "oNT-" have been carried out [ ]. Systematic reviews and guidelines recommend that "oNT injections should be offered as a treatment option for CD for which it has been proven to be effective and can be offered for blepharospasm, focal upper extremity dystonia and adductor laryngeal dystonia for which it is probably effective [ , ].The first study on the use of "oNT for CD was a single-blind study with patients and used electromyography...
