Understanding changes that may occur in the swallow with repetitive use in healthy individuals is a prerequisite to evaluate and treat persons with compromised swallowing. To determine any systematic effect of use on swallow function, we attempted to tax the swallow mechanism in a rigorous sequence of dry and liquid swallow conditions. Oropharyngeal temporal measures were assessed videofluoroscopically...
The prolonged voluntary closure of the glottis during the supraglottic and super-supraglottic swallowing techniques may create the Valsalva maneuver. The Valsalva maneuver has been associated with sudden cardiac death and cardiac arrhythmias. This study describes the effects of the supraglottic and super-supraglottic swallowing techniques on the cardiovascular system. Subjects included 23 patients...
Research has shown that swallowing in adults is affected by bolus consistency. Little is known, however, regarding the effect of bolus consistency on swallowing in children. Electromyographic (EMG) data from typically developing five- and eight-year-old-children and adults were obtained from the following muscles as they swallowed boluses of different consistencies: (1) right upper lip, (2) right...
Cervical auscultation is in the process of gaining clinical credibility. In order for it to be accepted by the clinical community, the procedure and equipment used must first be standardized. Takahashi et al. [Dysphagia 9:54-62, 1994] attempted to provide benchmark methodology for administering cervical auscultation. They provided information about the acoustic detector unit best suited to picking...
Background: Two approaches can be used for treating Zenker's diverticulum operatively: external or endoscopic. Methods: The records of 52 patients who underwent Zenker's diverticulum endoscopically were evaluated retrospectively. Twenty-two patients were treated with endoscopic scissors and 30 patients by carbon dioxide laser resection. The therapeutic concept of rigid endoscopic diverticulotomy was...

Epiglottic movement patterns of 500 consecutive patients with varying etiologies were recorded during routine videofluoroscopic swallow evaluations. Seven distinct, commonly repeated, abnormal epiglottic patterns were identified. A multifactorial analysis of these seven abnormal epiglottic movement patterns was completed. Findings indicate that each of these seven distinct movement patterns have varying...
This study investigated the swallowing physiology of 13 patients [age 27-69 years (mean = 45 years)] with multiple sclerosis (MS) who had Kurtzke Extended Disability Status Scale (EDSS) scores ranging from 2 to 9 (mean = 6) and who complained of difficulty swallowing. Videofluoroscopic recordings of the patients' calibrated liquid and paste bolus swallows were analyzed and compared with publi-shed...

Our goal was to determine and compare vocal cord (VC) closure pressure and its associated intratracheal pressure during several physiological events such as swallowing, coughing, straining, and phonation. We studied 11 healthy subjects (age 41 ± 2 years) with no current or previous history of laryngeal or pulmonary diseases. VC closure pressure during the above-mentioned tasks was studied using a...

The hypertensive lower esophageal sphincter (HLES) is a disorder of esophageal motility associated with dysphagia and chest pain. Although well characterized manometrically, opinions differ greatly with regard to its pathophysiology and its management. Therapy is limited to a few medications, esophageal dilatation, and even surgery, although none of these options are consistently successful. In this...
Surface electromyography (EMG) has been used successfully in teaching patients swallow maneuvers in clinical settings. The present study aims to determine if surface EMG can reliably demonstrate differences in muscle activity between the normal swallow and the Mendelsohn maneuver and whether there is a close temporal relationship between submental muscles and laryngeal elevation as demonstrated by...
