ABSTRACT BACKGROUND: Dysphagia is described as a complaint in 32% of patients with laryngitis. OBJECTIVE: The objective of this investigation was to evaluate oral and pharyngeal transit of patients with laryngitis, with the hypothesis that alteration in oral-pharyngeal bolus transit may be involved with dysphagia. METHODS: Videofluoroscopic evaluation of the swallowing of liquid, paste and solid boluses was performed in 21 patients with laryngitis, 10 of them with dysphagia, and 21 normal volunteers of the same age and sex. Two swallows of 5 mL liquid bolus, two swallows of 5 mL paste bolus and two swallows of a solid bolus were evaluated in a random sequence. The liquid bolus was 100% liquid barium sulfate and the paste bolus was prepared with 50 mL of liquid barium and 4 g of food thickener (starch and maltodextrin). The solid bolus was a soft 2.2 g cookie coated with liquid barium. Durations of oral preparation, oral transit, pharyngeal transit, pharyngeal clearance, upper esophageal sphincter opening, hyoid movement and oral-pharyngeal transit were measured. All patients performed 24-hour distal esophageal pH evaluation previous to videofluoroscopy. RESULTS: The evaluation of 24-hour distal esophageal pH showed abnormal gastroesophageal acid reflux in 10 patients. Patients showed longer oral preparation for paste bolus and a faster oral transit time for solid bolus than normal volunteers. Patients with laryngitis and dysphagia had longer preparation for paste and solid boluses, and a faster oral transit time with liquid, paste and solid boluses. CONCLUSION: A longer oral preparation for paste and solid boluses and a faster transit through the mouth are associated with dysphagia in patients with laryngitis.

ABSTRACT Background There are some studies in the literature about the feeding behavior and masticatory process in patients with feeding disorders; however, it is not very well known if there are alterations in oral-pharyngeal swallowing dynamics in subjects with anorexia nervosa. Objective To evaluate the oral and pharyngeal bolus transit in patients with anorexia nervosa. Methods The study was conducted with 8 individuals clinically diagnosed and in treatment for restricting-type anorexia nervosa (seven women and one man), and 14 healthy individuals with no digestive or neurological symptoms (10 women, 4 men). Swallows were evaluated by videofluoroscopy with three swallows of 5 mL liquid bolus and three swallows of 5 mL paste bolus consistency, given in a random sequence. The participants were asked after each swallow about the sensation of the bolus passage. Results In the analysis of oral-pharyngeal transit duration, the mean duration of pharyngeal transit with paste bolus in patients with anorexia was shorter than in healthy volunteers (P=0.02). In the duration of movement of the hyoid bone, longer movement was observed in anorexia than in healthy volunteers with liquid bolus (P=0.01). With liquid bolus, five (62.5%) patients and one (7.1%) control had sensation of the bolus passage (P<0.05). Conclusion There seems to be no important alterations of swallowing in subjects with anorexia nervosa, although the results suggest that pharyngeal transit has shorter duration than that seen in healthy volunteers and the hyoid movement duration is longer in patients than in healthy volunteers. Fast pharyngeal transit may be the cause of bolus transit perception in patients with anorexia nervosa.

Liquid Bolus

Abstract Thickened fluids are commonly used in the medical management of individuals who suffer swallowing difficulty (known as dysphagia). Previous studies have shown that the rheological properties of a liquid affect the flow behavior of the bolus in swallowing, such as pharyngeal transit time. While there is no doubt that shear rheology is a highly important factor for bolus flow, it is suspected that extensional properties of a liquid bolus also plays an important role in swallowing, due to elongation of the bolus as it flows through the oropharynx. Our aim in this work was to observe the effect of extensional viscosity on pharyngeal transit time and elongation of the bolus during swallowing. Eight samples of thickened liquid barium that were shear-controlled, but varied in extensional viscosity and two samples that were extensional-controlled, but varied in shear viscosity were swallowed by eight healthy individuals. Data were collected under lateral view of videofluoroscopy swallow study (VFSS); measures of pharyngeal transit time and the ratio of the length to the width of the bolus on the frame of Upper Esophageal Sphincter (UES) opening were taken from the VFSS recordings. It was observed that the pharyngeal transit time generally increases when the fluids are thickened to higher IDDSI consistency. Additionally, higher extensional viscosity fluids reduced the elongation of the bolus during swallowing, thus potentially reducing the risk of post-swallow residue due to bolus breakage. This study confirmed the relevance of the extensional viscosity of the bolus in swallowing.
