Dysphagia in Open Partial Horizontal Laryngectomy Type IIa: Quantitative Analysis of Videofluoroscopy using the ASPEKT Method. Dysphagia 2024; 39:964-973.

Abstract
Open Partial Horizontal Laryngectomy (OPHL) Type IIa surgery is a conservative surgical technique used in the treatment of laryngeal carcinomas. In this pilot study, we aimed to characterize swallowing function and physiology in a series of patients after OPHL Type IIa surgery through comparison to healthy reference values for quantitative measures for videofluoroscopy. We performed retrospective quantitative analysis of videofluoroscopy recordings of thin liquid swallows for a preliminary sample of 10 male patients. Each videofluoroscopy clip was rated in triplicate by trained blinded raters according to the ASPEKT Method (Analysis of Swallowing Physiology: Events, Kinematics and Timing). This preliminary sample of patients with previous OPHL surgery showed functional airway protection, with only 2 patients showing incomplete laryngeal vestibule closure (LVC) and associated airway invasion. However, the majority of patients (90%) showed prolonged latencies to LVC and upper esophageal sphincter (UES) opening. Prolonged durations of LVC and UES opening were also noted, but these were in the direction of compensation rather than impairment. Reduced pharyngeal area at rest was seen in 70% of the sample, and all patients showed poor pharyngeal constriction. Post-swallow residue was a prominent finding in ≥ 75% of these patients. In particular, reduced or absent constriction of the hypopharynx in the region of the pyriform sinuses was noted as a characteristic of swallowing in this sample. The data from these patients suggest that despite functional airway protection, severe swallowing dysfunction involving poor pharyngeal constriction and bolus clearance may be likely after OPHL surgery.

Abstract
PURPOSE The videofluoroscopic swallowing study (VFSS) is used widely in dysphagia research. However, variations exist in the conduct and interpretation of VFSS, including differences in contrast agents, food and fluid consistencies tested, patient positioning, intervention strategies trialed, fluoroscopy settings, resolution, and image storage solutions. It cannot be assumed that VFSS exams yield directly comparable results across different studies. It is essential that relevant elements of VFSS be clearly reported in research. The goal of this article is to outline optimal VFSS reporting as part of the Framework for RigOr aNd Transparency In REseaRch on Swallowing (FRONTIERS), a critical appraisal tool intended to promote rigor and transparency in dysphagia research. METHOD We developed a set of 27 questions regarding the rigor and transparency of VFSS reporting, based on review of previous research articles. These were reviewed by all members of the FRONTIERS Framework collaborative, to determine which questions were mandatory, unnecessary, or needed revision, prior to inclusion in the final critical appraisal tool. RESULTS The final FRONTIERS Framework tool contains 20 questions and seven subquestions regarding VFSS. These are grouped into four themes: patient/participant positioning, equipment and recording settings, contrast agents, and rating methods, including operational definitions and reliability. CONCLUSIONS The VFSS section of the FRONTIERS Framework tool is intended to facilitate and promote rigorous and transparent reporting of all elements that may influence the interpretation of VFSS in research. This critical appraisal tool can also be used to guide research design and the evaluation of study outcomes contributing to best practices in the field of dysphagia research.

Abstract
Videofluoroscopic swallowing study (VFSS), alongside flexible endoscopic evaluation of swallowing, represents the gold standard for diagnosing swallowing disorders and to determine severity, pathophysiology, and effective interventions, including texture modification. The clinical swallowing examination and assessment supplements these instrumental methods and serves as the basis for the modules of swallowing diagnostics. The adaptation of food and drink consistencies in dysphagia management has become widespread. For valid results of a VFSS with respect to confirming swallowing safety and efficiency of different liquid and food consistencies and textures, the use of uniform recipes containing radio-opaque contrast media is important. Our goal was to identify recipes that would produce consistencies that conform to the liquid and food levels of 0-7, as defined by the International Dysphagia Diet Standardization Initiative (IDDSI), with barium- and iodine-based contrast media, xanthan gum-based thickeners, and other edible components, which also show sufficient contrast on VFSS. In this study, we determined the different recipes using IDDSI testing methods and explored their radiological characteristics using a Philips MultiDiagnost Eleva fluoroscopy system and two different fluid contrast agents: barium- (Micropaque®) and iodine-based (Telebrix®). All recipes showed sufficient contrast on fluoroscopy and could be visualized in the amounts used for swallowing examinations. They were practical and easy to implement in terms of production and availability of the components. The homogeneity of the recipes diminished with higher IDDSI levels, which represent transitional food, but appeared still sufficient for fluoroscopic examination. The opacity did not significantly differ between the barium- and iodine-based contrast media.

Abstract
BACKGROUND People recurrently have difficulties swallowing solid medications, which can be associated with the size of the medication and the age and gender of individuals. OBJECTIVE To evaluate the impact of capsule size and adults' age and gender on oral and pharyngeal capsule transit during capsule swallows. METHODS Videofluoroscopy was used to measure capsule oral and pharyngeal transit during swallows in 49 healthy individuals (17 men and 32 women), with a mean age of 46 years (ranging from 23 to 88 years). Smaller capsules were filled with 0.50 mL of barium sulfate, and larger capsules were filled with 0.95 mL of barium sulfate; the volume of liquid ingested with the capsules was also quantified in each ingestion. The measurements included the oral preparation time, oral transit time, swallowing reaction time, time to laryngeal vestibule closure, laryngeal vestibule closure duration, pharyngeal transit time, and upper esophageal sphincter opening duration. RESULTS The capsule size did not influence either the oral or pharyngeal transit time. Increased liquid volume was ingested with larger capsules and by people older than 40 years. The oral transit time was shorter in older adults (60-88 years), and the time to laryngeal vestibule closure was longer in women. CONCLUSION The size of large capsules did not make a difference in oral or pharyngeal transit when compared with smaller capsules. The capsule size and the participant's age influenced the volume of liquid ingested - larger capsules and older individuals required a larger volume. The capsule oral transit was faster in individuals older than 60 years. BACKGROUND •Swallowing is influenced by the characteristics of what is being swallowed. BACKGROUND •There was no difference in swallowing capsules containing 0.50 mL or 0.95 mL. BACKGROUND •Larger capsules need more liquid ingestion to make swallowing easier. BACKGROUND •Individuals older than 40 years need a greater volume of liquid to swallow capsules than younger adults.

Abstract
During videofluoroscopic swallowing study (VFSS), barium sulfate (BaSO4 ) is commonly added into food samples as a radiopaque contrast media for bolus visualization and examination. Accordingly, the consistency and flow behavior of barium stimuli can differ significantly from their non-barium counterparts. Such differences may have a subsequent impact on the validity of VFSS. Therefore, in this study, effects of barium sulfate on the shear and extensional rheological properties and IDDSI (International Dysphagia Diet Standardization Initiative) flow consistency of liquids prepared using various commercial thickening powders were investigated. Results showed that all barium stimuli exhibited shear thinning behavior but with significantly higher shear viscosity compared to the non-barium counterparts. A shift factor of viscosity at shear rate 50 s-1 with values in range of 1.21-1.73 could be used to describe the increase in the viscosity for samples thickened with gum-based thickeners. However, the change in the viscosity was not invariant for the stimuli prepared starch-based thickener. The addition of BaSO4 had a negative impact on extensional properties of samples by demonstrating a faster filament rupture. The extent of impact on the decrease in filament breakup time was more pronounced in xanthan > guar gum ≈ tara gum-based thickeners. Based on the IDDSI flow test, no significant effect of BaSO4 was found on the gum-based thickeners, whereas there was a marked effect in the starch-based sample. These results can be used beneficially to assist clinicians in the dysphagia diagnosis for matching rheological properties of the barium stimuli to enhance effectiveness dysphagia interventions.

Abstract
PURPOSE It is essential that clinicians have evidence-based benchmarks to support accurate diagnosis and clinical decision making. Recent studies report poor reliability for diagnostic judgments and identifying mechanisms of impairment from videofluoroscopy (VFSS). Establishing VFSS reference values for healthy swallowing would help resolve such discrepancies. Steele et al. (2019) released preliminary reference data for quantitative VFSS measures in healthy adults aged < 60 years. Here, we extend that work to provide reference percentiles for VFSS measures across a larger age span. METHOD Data for 16 VFSS parameters were collected from 78 healthy adults aged 21-82 years (39 male). Participants swallowed three comfortable sips each of thin, slightly, mildly, moderately, and extremely thick barium (20% w/v). VFSS recordings were analyzed in duplicate by trained raters, blind to participant and task, using the Analysis of Swallowing Physiology: Events, Kinematics and Timing (ASPEKT) Method. Reference percentiles (p2.5, 5, 25, 50, 75, 95, and 97.5) were determined as per Clinical and Laboratory Standards Institute EP28-A3c guidelines. RESULTS We present VFSS reference percentile tables, by consistency, for (a) timing parameters (swallow reaction time; the hyoid burst-to-upper esophageal sphincter (UES)-opening interval; UES opening duration; time-to-laryngeal vestibule closure (LVC); and LVC duration) and (b) anatomically scaled pixel-based measures of maximum UES diameter, pharyngeal area at maximum pharyngeal constriction and rest, residue (vallecular, pyriform, other pharyngeal locations, total), and hyoid kinematics (X, Y, XY coordinates of peak position; speed). Clinical decision limits are proposed to demarcate atypical values of potential clinical concern. CONCLUSION These updated reference percentiles and proposed clinical decision limits are intended to support interpretation and reliability for VFSS assessment data.

JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2023; 66:863-871. [PMID: 36780312 PMCID: PMC10205107 DOI: 10.1044/2022_jslhr-22-00465] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 11/03/2022] [Accepted: 11/20/2022] [Indexed: 05/25/2023]
Abstract
PURPOSE Videofluoroscopic (VFSS) measurements of pharyngeal swallow mechanics can differentiate age- and disease-related changes in swallowing. Pharyngeal area at rest (PhAR) may differ in people with dysphagia, although its impact is not clear. Before the role of PhAR in dysphagia can be explored, it is important to establish whether PhAR remains stable across repeated measures in healthy adults, and varies as a function of sex or age. We hypothesized that healthy adults would show stable PhAR across repeated measures, but that larger PhAR would be seen in men versus women and in older versus younger adults. METHOD We collected VFSS data from 87 healthy adults (44 men, M age = 46 years, range: 21-82). Trained raters identified the swallow rest frame after the initial swallow of each bolus and measured unobliterated pharyngeal area on these frames, in %(C2-4)2 units. Repeated-measures analyses of variance with a factor of sex, a covariate of age, and a repeated factor of task repetition were performed across the first 12 available measures per participant (N = 1,044 swallows). RESULTS There were no significant variations in PhAR across repeated measures. A significant Sex × Age interaction was seen (p = .04): Males had significantly larger PhAR than females (p = .001), but females showed larger PhAR with advancing age (R = .47). CONCLUSIONS These data confirm stability in PhAR across repeated measurements in healthy individuals. However, significant sex and age differences should be taken into consideration in future studies exploring the role of PhAR in people with dysphagia.
