The acute tendinitis of the longus colli muscle is an unusual diagnosis in the cases of acute dysphagia with cervical pain. Is a self-limiting condition caused by abnormal calcium hydroxyapatite deposition in the prevertebral space and can cause pharyngeal swelling with impaired swallow. It is absolutely critical to make the differential diagnosis with deep cervical infections in order to avoid invasive...
Submental surface electromyography (ssEMG) visual biofeedback is widely used to train swallowing maneuvers. This study compares the effect of ssEMG and videofluoroscopy (VF) visual biofeedback on hyo-laryngeal accuracy when training a swallowing maneuver. Furthermore, it examines the clinician’s ability to provide accurate verbal cues during swallowing maneuver training. Thirty healthy adults performed...
Research using animal models has contributed significantly to realizing the goal of understanding dysfunction and improving the care of patients who suffer from dysphagia. But why should other researchers and the clinicians who see patients day in and day out care about this work? Results from studies of animal models have the potential to change and grow how we think about dysphagia research and...
This article reviews the history of the barium swallow from its early role in radiology to its current status as an important diagnostic test in modern radiology practice. Though a variety of diagnostic procedures can be performed to evaluate patients with dysphagia or other pharyngeal or esophageal symptoms, the barium study has evolved into a readily available, non-invasive, and cost-effective technique...
The Eating Assessment Tool-10 (EAT-10) represents a validated, easy to administer patient report dysphagia severity scale. Although its ability to detect swallowing impairment has been investigated in other patient populations, the utility of this instrument in individuals with head and neck cancer (HNC) has not been studied. The aim of the current investigation was to determine the relationship between...
The art and science of using stents to treat dysphagia and seal fistula, leaks and perforations has been evolving. Lessons learnt from the deficiencies of previous models led to several improvements making stent deployment easier, and with some designs, it was also possible to remove the stents if needed. With these improvements, besides malignant dysphagia, newer indications for using stents emerged...
Feeding, swallowing, and airway protection are three distinct entities. Feeding involves a process of sequential, neurosensory, and neuromotor interactions of reflexes and behaviors facilitating ingestion. Swallowing involves anterograde bolus movement during oral-, pharyngeal-, and esophageal phases of peristalsis into stomach. During these events, coordination with airway protection is vital for...
Surface electromyography (sEMG) is used as an adjuvant to dysphagia therapy to demonstrate the activity of submental muscles during swallowing exercises. Mechanomyography (MMG) has been suggested as a potential superior alternative to sEMG; however, this advantage is not confirmed for signal acquired from submental muscles. This study compared the signal-to-noise ratio (SNR) obtained from sEMG and...
Determining intrabolus pressure (IBP) at the upper esophageal sphincter (UES) and in the esophagus has given compelling evidence that IBP can be a predictor for swallowing dysfunction. Studies have looked most superiorly at the low hypopharynx region but there has been no inquiry into what IBP measures throughout the entire pharynx can tell us. We present a study to describe the pressures within and...
As deglutologists, we strive to use the best evidence available in the treatment of swallowing disorders. Evidence-based medicine is a bottom-up approach that thoughtfully combines the best external evidence with individual clinical expertise and the patients’ choice reflective of their clinical state and preferences for their specific care plan. Evidence-based medicine is not restricted to randomized...
