Dermatomyositis is a rare multisystem autoimmune disorder occasionally accompanied by dysphagia. It is typically treated with immune modulating agents; however, dysphagia is often unresponsive to these. Previous reports have demonstrated the utility of videoflouroscopy and manometry in understanding the etiologies of dysphagia to inform a procedural target, historically the cricopharyngeus muscle. We present a case of dermatomyositis and dysphagia resistant to medical management in a patient found by videoflouroscopy and manometry to have severe oropharyngeal dysphagia, esophageal dysmotility and a cricopharyngeal web. We demonstrate the utility and safety of upper esophageal sphincter dilation by transnasal esophagoscopy even in the setting of multifactorial dysphagia.

Oropharyngeal dysphagia due to upper esophageal sphincter (UES) dysfunction is commonly encountered in the clinical setting. Selective experimental perturbation of various components of the deglutitive apparatus can provide an opportunity to improve our understanding of the swallowing physiology and pathophysiology. The aim is to characterize the pharyngeal and UES deglutitive pressure phenomena in an experimentally induced restriction of UES opening in humans. We studied 14 volunteers without any dysphagic symptoms (7 men, 66 ± 11 yr) but with various supraesophageal reflux symptoms. To induce UES restriction, we used a handmade device that with adjustment could selectively apply 0, 20, 30, or 40 mmHg pressure perpendicularly to the cricoid cartilage. Deglutitive pharyngeal and UES pressure phenomena were determined during dry and 5- and 10-ml water swallows × 3 for each of the UES perturbations. External cricoid pressure against the UES resulted in a significant increase in hypopharyngeal intrabolus pressure and UES nadir deglutitive relaxation pressure for all tested swallowed volumes ( P < 0.05). Application of external cricoid pressure increased the length of the UES high pressure zone from 2.5 ± 0.2 to 3.1 ± 0.2, 3.5 ± 0.1, and 3.7 ± 0.1 cm for 20, 30, and 40 mmHg cricoid pressure, respectively ( P < 0.05). External cricoid pressure had no significant effect on pharyngeal peristalsis. On the other hand, irrespective of external cricoid pressure deglutitive velopharyngeal contractile integral progressively increased with increased swallowed volumes ( P < 0.05). In conclusion, acute experimental restriction of UES opening by external cricoid pressure manifests the pressure characteristics of increased resistance to UES transsphincteric flow observed clinically without affecting the pharyngeal peristaltic contractile function.

Inclusion body myositis (IBM) is a progressive degenerative skeletal muscle disease leading to weakening and atrophy of both proximal and distal muscles. Dysphagia is reported in up to 86% of IBM patients. Surgical cricopharyngeal myotomy may be effective for cricopharyngeal dysphagia and there is one published report that botulinum toxin A, injected into the cricopharyngeus muscle using a hypopharyngoscope under general anesthesia, relieved IBM-associated dysphagia. This report presents the first documentation of botulinum toxin A injection into the upper esophageal sphincter using a flexible esophagogastroduodenoscope under conscious sedation, to reduce upper esophageal sphincter pressure and successfully alleviate oropharyngeal dysphagia in two IBM patients.

This study in three dogs explores the effect of magnetically induced electrical stimulation of the brain to induce swallowing and produce contraction of the upper esophageal sphincter (UES). Single stimuli were delivered at intervals from 15 s to 3 min. Studies were performed with and without perfusion of fluid into the pharynx and upper esophagus. Results showed that magnetic stimulation produced a twitch contraction of the UES when stimulus intensity was above a threshold that varied between 14 and 20% of the stimulator output. Increasing stimulus intensity progressively increased twitch amplitude. Magnetic stimulation also induced swallowing, above a stimulus threshold similar to that for induction of the UES twitch contraction. Fluid perfusion augmented the ability of the magnetic stimulus to induce swallowing. We concluded that a magnetically induced single electrical stimulus of the cerebral cortex produces UES contraction and induces swallowing. The effect on swallowing is facilitated by sensory stimulation of the pharynx. This technique holds the potential for further study of 1) motor and sensory neural mechanisms involved in the control of swallowing and 2) the assessment and management of oropharyngeal dysphagia in humans.

A wide variety of disorders can affect the pharynx and upper esophagus, such as inherited or acquired structural abnormalities, malignancies, and inflammation secondary to a number of etiologies including bacterial, yeast and viral infections, irradiation, and gastroesophageal reflux disorder. Laryngoceles and peritonsillar abscess can also lead to pain and dysfunction. However, this review will focus on the main motility disorders that affect the pharynx and upper esophagus, namely oropharyngeal dysphagia, disorders associated with globus pharyngeus, and Zenker’s diverticulum. Figures show the anatomy of the three stages of normal swallow, various findings on functional endoscopic evaluation of swallowing, electromyography of the cricopharyngeal sphincter and submental muscles, and Zenker’s diverticulum. Tables list causes of oropharyngeal dysphagia, neuromuscular control of the pharyngeal phase (with identified cranial and cervical spinal nerve roots), pathophysiology of oropharyngeal dysplasia, diagnostic tests for oropharyngeal dysplasia, behavioral treatments to improve swallow and reduce aspiration, and potential overlapping causes of impaired upper esophageal sphincter relaxation.   This review contains 4 highly rendered figures, 6 tables, and 40 references   Key words: Oropharyngeal dysphagia; Globus; Upper esophageal sphincter dysfunction; Swallowing disorder; Dysphagia; Zenker’s diverticulum; Swallow assessment; Globus pharyngeus

Abstract Dysphagia is defined as an impairment of this complex and integrated sensorimotor system. It is estimated that 400,000 to 800,000 individuals worldwide develop neurogenic dysphagia per year. Neurogenic dysphagia is typically occurring in patients with neurological disease of different etiologies. A correct and early diagnosis and an appropriate management of dysphagia could be useful for improving patient’s quality of life and may help to prevent or delay death. In the present review, we discuss thoroughly the anatomy and physiology of swallowing and also the pathophysiological mechanisms involved in impaired swallowing, as well as the diagnosis, management, and potential treatments of neurogenic dysphagia. Assessment of neurogenic dysphagia includes medical history, physical exam, and instrumental examinations (fiberoptic endoscopic evaluation of swallowing, videofluoroscopic swallowing study, electromyography). Pharmacological treatment of these problems includes oral anticholinergic drugs. Surgical myotomy of the cricopharyngeal muscle showed an important improvement of oropharyngeal dysphagia associated to upper esophageal sphincter hyperactivity. Chemical myotomy of the upper esophageal sphincter by local injections of botulinum toxin type A into the cricopharyngeal muscle has been proposed as an alternative less invasive and less unsafe than surgical myotomy.
