“…Many publications only cited the location considered ideal for the onset of the pharyngeal phase, for example, the region of the shadow of the mandibular ramus (23)(24)(25) , the fauces (26) and also the posterior nasal spine (27) and not describing the location in which the pharyngeal phase of swallowing was actually triggered. To a certain extent, this finding explains the small number of studies included in this review.…”

RESUMO Objetivo Revisar a literatura quanto aos locais de início da fase faríngea da deglutição em adultos e idosos, assintomáticos e sintomáticos. Estratégia de pesquisa Foi realizada pesquisa nas bases PubMed, BIREME e SciELO através dos descritores fluoroscopia (fluoroscopy), deglutição (deglutition) e faringe (pharynx). Critérios de seleção Estudos publicados entre 2005 e 2015, com adultos e idosos que realizaram videofluoroscopia da deglutição (VFD) e citaram o local de início da fase faríngea da deglutição. Análise dos dados Foi realizada análise descritiva e meta-análise, com estudo da heterogeneidade e de medidas agrupadas com efeito aleatório por meio da estatística I2. Para o cálculo de proporção na meta-análise, os locais descritos nos artigos foram classificados pelo Modified Barium Swallowing - Measurement Tool for Swallowing Impairment (MBSImp). Resultados Ao final, foram selecionados 12 artigos para análise descritiva e sete para meta-análise. Foi encontrada heterogeneidade entre os estudos, especialmente, devido às diferenças clínicas e metodológicas. O efeito aleatório indicou predominância (58%) do início da fase faríngea da deglutição nos níveis zero e um do MBSImP. Em indivíduos assintomáticos, observou-se o início da fase faríngea na cavidade oral, base da língua, dorso da língua e valécula. Em indivíduos sintomáticos, o início foi observado, principalmente, em orofaringe, valécula, hipofaringe e recessos piriformes. Conclusão Foi observada maior frequência de início da fase faríngea da deglutição em valécula. O início da fase faríngea em hipofaringe e recessos piriformes foi mais observado em indivíduos idosos ou com comorbidades que poderiam alterar a deglutição.

“…Omari et al reported that combined manometry and multichannel intraluminal impedance facilitated prediction of pharyngeal residue after swallowing 13 and other studies reported that a simple analysis of the impedance contour pattern (linear vs. stasis) could reveal pharyngeal residue. 5,14 As these analyses are qualitative rather than quantative, follow up studies are required for clinical application.…”

Application and Interpretation of High-resolution Manometry for Pharyngeal Dysphagia

The pharyngeal phase of swallowing is a complex event consisted with subsequent muscular contractions and pressure generation to move a bolus from the mouth to the esophagus. Recently, high-resolution impedance manometry (HRIM) was developed and used for the evaluation of pharyngeal dysphagia. Although HRIM provides precise pharyngeal pressure information, it has yet to be used as part of routine clinical practice for the assessment of dysphagia. The main reasons are thought to be that the test method and result interpretation are not easily applicable and standardized. The anatomical landmarks for HRIM parameters are velopharynx, tongue base, epiglottis, low pharynx, and upper esophageal sphincter. With HRIM, the pressure and timing data could be obtained at a precise anatomical structure. In the present review, we will review how to apply HRIM for the evaluation of pharyngeal dysphagia, including the interpretation of its parameters.

“…Therefore, a simpler measurement method is needed for prediction of pharyngeal residue. We have previously evaluated the utility of HRIM-based qualitative impedance for detection of pharyngeal residue in small study of 20 healthy volunteers and 10 OPD patients that used a pre-set cut-off of 1,000 Ω, 15 which was arbitrarily selected for color impedance analysis. We have observed a linear pattern (vertical line) under a value of 1,000 Ω in the impedance color bar of the subjects without pharyngeal residue in the videofluoroscopic swallowing study (VFSS), while a stasis pattern (a horizontal square) was seen in the subjects with pharyngeal residue.…”

Background/AimsImpedance analysis using high-resolution impedance manometry (HRIM) enables the recognition of pharyngeal residue in patients with oropharyngeal dysphagia. The aims of this study were to evaluate appropriate criteria for impedance analysis in a large patient cohort, as well as the diagnostic accuracy and agreement of analysis performed by HRIM trainees. MethodsWe reviewed 33 controls (13 males; median age, 61.2 years) and 104 oropharyngeal dysphagia patients (61 males; median age, 70.4 years) who underwent a flexible endoscopic evaluation of swallowing study (FEES) and HRIM. Two experts compared the pharyngeal residue on FEES and impedance color pattern at 1,000, 1,500 and 2,000 Ω of the impedance bar. Three trainees were given a 60 minutes tutorial to determine the diagnostic accuracy and agreement of this analysis. ResultsThe diagnostic sensitivity of experts for predicting liquid residue was 73.1% for 1,000 Ω, 96.2% for 1,500 Ω and 100% for 2,000 Ω. Significantly higher sensitivity was observed at 1,500 Ω compared to 1,000 Ω (P < 0.001). The diagnostic specificity of experts for liquid residue was 98.3% for 1,000 Ω, 96.6% for 1,500 Ω and 83.1% for 2,000 Ω. There was a higher specificity at 1,500 Ω compared to 2,000 Ω (P = 0.008). The κ value among the 3 trainees was 0.89 and the diagnostic accuracy of the trainees for liquid residue was comparable to that of the experts.
