Fiberoptic Endoscopy Evaluation of Swallowing (FEES) Findings Associated with High Pneumonia Risk in a Cohort of Patients at Risk of Dysphagia.

Aspiration detected in the fiberoptic endoscopy evaluation of swallowing (FEES) has been inconsistently associated with pneumonia, with no evidence of the risk of pneumonia from other alterations in swallowing safety detected in FEES. We conducted a dynamic, ambidirectional cohort study involving 148 subjects at risk of dysphagia in a tertiary university hospital. Our aim was to determine the risk of pneumonia attributed to alterations in swallowing safety detected during FEES. We used multivariate negative binomial regression models to adjust for potential confounders. The incidence density rate (IR) of pneumonia in patients with tracheal aspiration of any consistency was 26.6/100 people-years (RR 7.25; 95% CI: 3.50-14.98; P < 0.001). The IR was 19.7/100 people-years (RR 7.85; 95% CI: 3.34-18.47; P < 0.001) in those with laryngeal penetration of any consistency and 18.1/100 people-years (RR 6.24; 95% CI: 2.58-15.09; P < 0.001) in those with pharyngeal residue of any consistency. When adjusted for aspiration, the association of residue and penetration with pneumonia disappeared, suggesting that their risk of pneumonia is dependent on the presence of aspiration and that only aspiration is independently associated with pneumonia. This increased risk of pneumonia was significant in uni- and multivariate negative binomial regression models. We found an independently increased risk of pneumonia among patients with dysphagia and aspiration detected during FEES. Alterations in the oral and pharyngeal phases of swallowing, without aspiration, did not increase the risk of pneumonia.

Prediction of postoperative dysphagia in patients with oral cancer: a prospective cohort study.

OBJECTIVES: This study aims to identify autonomous risk factors for postoperative dysphagia in oral cancer patients and construct a nomogram prediction model to improve risk assessment accuracy and feasibility in clinical settings. METHODS: A prospective cohort study was conducted from March to July 2022 among oral cancer patients undergoing surgical interventions at the Department of Head and Neck Surgery. Clinical data were collected using the Postoperative Dysphagia Risk Factor Questionnaire. Swallowing function was assessed with the Mann Assessment of Swallowing Ability-Oral Cancer (MASA-OC). Lasso regression identified potential predictor variables, followed by univariate and multivariate logistic regression analyses. A predictive model was developed using R Studio 4.1.2 and rigorously evaluated with ROC curves, Hosmer-Lemeshow tests, and calibration curves. Internal validation utilized Bootstrap methodology with 1000 repetitive samples. RESULTS: The cohort included 257 oral cancer patients, with 73.9% experiencing postoperative dysphagia. Independent predictors included functional status, depressive symptoms, pT stage, surgical techniques, glossoplasty, maxillectomy, and post-surgery nasopharyngeal tube retention. The predictive model achieved an AUC of 0.933, sensitivity of 90.9%, and specificity of 81.7%. Hosmer-Lemeshow test (P = 0.715) and C-index (0.934) indicated satisfactory model fit. Internal validation yielded an AUC of 0.912, sensitivity of 93.3%, and specificity of 63.8%. Calibration curves demonstrated alignment between predicted and observed outcomes. CONCLUSION: A nomogram integrating recognized risk factors shows promise in predicting postoperative dysphagia in oral cancer patients, enhancing precision and aiding healthcare professionals in risk evaluation and patient care strategies.

Predictors for Failed Removal of Nasogastric Tube in Patients With Brain Insult.

OBJECTIVE: To construct a prognostic model for unsuccessful removal of nasogastric tube (NGT) was the aim of our study. METHODS: This study examined patients with swallowing disorders receiving NGT feeding due to stroke or traumatic brain injury in a regional hospital. Clinical data was collected, such as age, sex, body mass index (BMI), level of activities of daily living (ADLs) dependence. Additionally, gather information regarding the enhancement in Functional Oral Intake Scale (FOIS) levels and the increase in food types according to the International Dysphagia Diet Standardization Initiative (IDDSI) after one month of swallowing training. A stepwise logistic regression analysis model was employed to predict NGT removal failure using these parameters. RESULTS: Out of 203 patients, 53 patients (26.1%) had experienced a failed removal of NGT after six months of follow-up. The strongest predictors for failed removal were age over 60 years, underweight BMI, total dependence in ADLs, and ischemic stroke. The admission prediction model categorized patients into high, moderate, and low-risk groups for removal failure. The failure rate of NGT removal was high not only in the high-risk group but also in the moderate-risk groups when there was no improvement in FOIS levels and IDDSI food types. CONCLUSION: Our predictive model categorizes patients with brain insults into risk groups for swallowing disorders, enabling advanced interventions such as percutaneous endoscopic gastrostomy for high-risk patients struggling with NGT removal, while follow-up assessments using FOIS and IDDSI aid in guiding rehabilitation decisions for those at moderate risk.

Pharyngeal Residues Scoring through the Yale Pharyngeal Residue Severity Rating Scale (YPRSRS): Efficacy of Training.

The assessment of pharyngeal residues during fiberoptic endoscopic evaluation of swallowing (FEES) is based on visual-perceptual scales that involve clinical subjectivity. Training might be helpful to increase agreement among clinicians. This paper aims to assess the efficacy of training for the assessment of pharyngeal residue in FEES frames and videos through the Yale Pharyngeal Residue Severity Rating Scale (YPRSRS). Twenty-nine clinicians (Phoniatricians, Otorhinolaryngologists, Speech and Language Pathologists) and 47 students in Speech and Language Pathology participated in this study. Fourteen clinicians were randomly allocated to the training group, whilst the remaining 15 served as a control group; all the students participated in the training. Participants scored 30 pairs of videos and frames using the YPRSRS twice, before and after the training for the training groups and at least two weeks apart for the control group. Construct validity, defined as the agreement between each rater and the experts' scores, and inter-rater reliability were compared among the groups and between the first and the second assessments to verify the efficacy of the training. Construct validity significantly improved at the second assessment in the training group for the pyriform sinuses videos (baseline 0.71 ± 0.04, post-training 0.82 ± 0.05, p = .049) and in the students' group for the valleculae (baseline 0.64 ± 0.02, post-training 0.84 ± 0.02, p < .001) and pyriform sinuses videos (baseline 0.55 ± 0.03, post-training 0.77 ± 0.02, p < .05). No significant differences were found in the inter-rater reliability in any group. In conclusion, the training seems to improve participants' agreement with experts in scoring the YPRSRS in FEES videos.

Nutritional Issues in Children with Dysphagia.

(1) Background: Pediatric dysphagia presents significant nutritional challenges, often impacting growth and development due to reduced oral intake, increased nutritional needs, and gastrointestinal complications; (2) Methods: This prospective quasi-experimental study assessed 117 children under 14 years old (20 patients were under 1 year old, 80 were aged 1-7 years, and 17 were older than 7 years), diagnosed with swallowing disorders, to analyze their caloric, macro-, and micronutrient intake and identify potential deficiencies. The severity of dysphagia was established using functional oral intake scales, and dietary records were reviewed over a 3-day period; (3) Results: The study revealed that 39.8% of participants did not meet their total energy expenditure (TEE), highlighting a high prevalence of malnutrition among these children. Furthermore, patients using feeding devices exhibited a significantly lower caloric intake, and over half required significantly modified food textures. After individualized speech therapy and nutritional rehabilitation, participants showed significant improvements in caloric intake, with their energy coverage increasing from 958% to 1198% of the daily requirement. Rehabilitation also improved tolerance to a broader range of food textures; (4) Conclusions: This research underscores the importance of multidisciplinary, individualized nutritional strategies to address the specific challenges of pediatric dysphagia, emphasizing the role of enteral nutrition and therapeutic interventions in improving the quality of life and nutritional outcomes of these children. Further studies are recommended to assess the long-term impact of such strategies.

Dysphagia characteristics at FEES examination in post-extubation patients with COVID-19.

Objective: The aims of this study was to analyse fibreoptic endoscopic evaluation of swallowing (FEES) findings in tube-fed patients with coronavirus disease 2019 (COVID-19). Methods: Seventeen patients who had been intubated during intensive care unit (ICU) stay were enrolled. Pooling of secretions, dysphagia phenotype, penetration/aspiration and residue after swallow were assessed through FEES. The Functional Oral Intake Scale (FOIS) scores were also collected. Patients with significant swallowing impairment were evaluated again after 2 weeks. Results: All patients were tube-fed at enrollment. According to the FEES results, 7 started total oral feeding with at least one consistency. The more common dysphagia phenotypes were propulsive deficit and delayed pharyngeal phase. Pooling of secretions, penetration/aspiration, and residue after swallow were frequently documented. A significant improvement in FOIS scores was found during the second FEES examination. Conclusions: Swallowing impairment in patients with severe COVID-19 after discharge from the ICU is characterised by propulsive deficit and delayed pharyngeal phase. Most of these patients required feeding restrictions even if feeding abilities seem to improve over time.

Oropharyngeal Dysphagia Phenotypes Across Huntington's Disease Stages: Endoscopic Findings and Tongue Pressure Analysis.

Background: Oropharyngeal dysphagia (OD) is a common symptom in Huntington's disease (HD) and is associated with severe health and psychosocial consequences. Different OD phenotypes are defined on the basis of characteristic patterns at fiberoptic endoscopic evaluation of swallowing (FEES), and they may vary during disease progression. Objective: To describe OD phenotypes in different HD stages and to analyze their association with neurological data and tongue pressure measurements. Methods: Twenty-four patients with HD at different stages of disease progression underwent a FEES. Data on penetration/aspiration, pharyngeal residue, and OD phenotypes were gained. Neurological examination was performed with the Unified Huntington's Disease Rating Scale (UHDRS). Patient Maximum tongue pressure (MTP) and tongue endurance were measured. Results: We confirmed that the occurrence of penetration/aspiration increased with disease duration and pharyngeal residue increased from 16.7% to 100%, respectively. The most common OD phenotypes were oropharyngeal dyspraxia (91.7%), posterior oral incontinence (87.5%), and delayed pharyngeal phase (87.5%). These types of dysfunctions are already detectable in >80% of patients in the early disease stages. In more advanced stages, we also observed propulsion deficit (66.7%), resistive issue (54.2%), and protective deficit (37.5%). Propulsion deficit was associated with higher disease stage, greater motor dysfunction (UHDRS-I), and lower MTP and tongue endurance (p < 0.05). Conclusions: OD in HD results from a combination of different swallowing phenotypes. Early assessment of swallowing and periodical follow-ups are necessary to monitor OD severity and phenotypes and to revise diet recommendations.

Fiberoptic endoscopic evaluation of swallowing (FEES) in pediatrics: A systematic review.

OBJECTIVES: The systematic review aimed to provide an overview of the state-of-art regarding the use of fiberoptic endoscopic evaluation of swallowing (FEES) in pediatrics, specifically investigating FEES feasibility, safety, diagnostic accuracy, and protocols. METHODS: Four electronic databases were searched for original studies on the pediatric population that instrumentally assessed swallowing function using FEES. A hand-search of the references of included studies was performed. Data on the population, feasibility of endoscope insertion and bolus trials, adverse events, sensitivity and specificity, and FEES equipment and protocol were extracted. The quality of the studies was assessed using the checklists of the Johanna Briggs Institute. Selection of the studies, data extraction, and quality appraisal were conducted by two independent researchers. RESULTS: Eighty-two reports from 81 studies were included. The mean overall quality of the studies was 80 % (17-100 %). The feasibility of endoscope insertion was high (89%-100 %), while the feasibility of bolus trials varied from 40 % to 100 %. Adverse events were excessive crying (8 studies), irritability or agitation (4 studies), transitory oxygen desaturations (3 studies, 1.2-6.7 % of the patients), epistaxis (3 studies, 0.8-3.3 % of the patients), increased heart rate (1 study, 1 patient), vomiting (1 study, 1 patient), hypertonia (1 study), and hypersalivation (1 study). No major complications were reported. Using VFSS as the reference standard, FEES was generally found to be less sensitive (25-94 %) but more specific (75-100 %) for aspiration, whereas the reverse was true for penetration (sensitivity 76-100 %, specificity 44-83 %). FEES protocols were highly heterogeneous with poor reporting. CONCLUSION: FEES is a safe, accurate, and generally feasible examination in the pediatric population with suspected dysphagia. However, a consensus on the best FEES protocol for clinical practice and research is currently lacking.

Alternatives for the administration of oral antineoplastics in patients with swallowing difficulties.

Oncology patients often experience swallowing difficulties, which can compromise adherence to treatment and consequently reduce its effectiveness. Improper handling of these hazardous drugs can lead to the risk of inhalation of particles or other exposures endangering the health of the persons involved such as nurses and pharmacists. The aim of this review is to analyse and update the recommendations for the manipulation of oral antineoplastic drugs in patients with swallowing difficulties. A literature review of articles, websites, guidelines and other documents published up to about the conditions of handling and administration of oral antineoplastic agents in oncology and oncohaematology was carried out. A table of 110 active principles was compiled. The information was grouped according to the name of the drug, instructions for oral and nasogastric tube administration and suggested recommendations. Among the drugs reviewed, 66.4% were suitable for dissolution. Although there is a lot of information in the literature, the nonstop development of new oncological drugs requires continuous updating. Therefore, we have collected the most recent data to provide a consultation tool for healthcare professionals and patients with swallowing difficulties.

This review can be used by all types of healthcare professionals, especially nurses, who handle oncological medicinal drugs. In addition, the safest handling methods for the worker have been recommended.

Evaluation of clinical factors predicting dysphagia in patients with traumatic and non-traumatic cervical spinal cord injury: a retrospective study.

Introduction: Dysphagia is a common complication in patients with cervical spinal cord injury (C-SCI) and can cause various pulmonary complications, such as aspiration pneumonia and mechanical airway obstruction increasing mortality and morbidity. This study evaluated the clinical factors that predict dysphagia in patients with traumatic and non-traumatic C-SCI. Methods: Ninety-eight patients with C-SCI were retrospectively enrolled in this study and were divided into those with and without dysphagia. Clinical factors such as age, sex, tracheostomy, spinal cord independence measure, pulmonary function test (PFT) including forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and FVC/FEV1, American Spinal Cord Injury Association score, Berg Balance Scale, and surgical approach were investigated retrospectively. Results: Multivariate logistic regression analysis revealed that FVC and the presence of tracheostomy were significantly correlated with dysphagia in patients with C-SCI (p < 0.05). FVC and the presence of tracheostomy are useful tools for detecting dysphagia in patients with C-SCI. Conclusion: Considering the results of our study, early PFTs, especially FVC, in patients with C-SCI and early initiation of dysphagia management and treatment in patients with C-SCI and tracheostomy will be advantageous in lowering the mortality and morbidity due to pulmonary aspiration in these patients.

Reliability of Measuring Geniohyoid Cross-Sectional Area with B-Mode Ultrasound.

B-mode ultrasound is a safe noninvasive procedure that has been used to characterize aspects of the oropharyngeal swallow. The submental suprahyoid muscles are often investigated with ultrasound because of their contributions to hyolaryngeal elevation. There are several techniques for positioning the ultrasound transducer in the coronal plane, however, there is limited research on how reliability of measurement of the cross-sectional area (CSA) of the geniohyoid differs across transducer placement technique. This study examined three methods of transducer placement in the coronal plane by two examiners to determine the reliability of measurement of CSA of the geniohyoid muscle. Forty healthy adults participated in the study. Each participant's geniohyoid muscles were imaged using B-mode ultrasound under three transducer placement conditions in the coronal plane by two examiners. Geniohyoid CSA was measured from each ultrasound image. A three-way mixed-methods ANOVA was used to determine whether there were significant differences in geniohyoid CSA among transducer position conditions, trials, and examiners. There were significant differences among the transducer placement conditions, indicating that each condition was measuring a different portion of the muscle. There were no significant differences among repeated trials nor between examiners within each method of transducer placement. All three conditions of transducer placement were reliable at measuring geniohyoid CSA across trials and examiners. This study emphasizes the need for consistency of placement, whichever method is selected. It also highlights the need for researchers to provide a precise description of methods for positioning the transducer so that placement is reproducible.

Methodological Procedures to Acquire and Analyze Ultrasound Images of Swallowing: A Scoping Review.

This scoping review aimed to identify methodological procedures for acquiring and analyzing ultrasound images related to swallowing in adults and older adults. The inclusion criteria were based on the PCC strategy (participants, concept, and context), as follows: population (adults and older adults), concept (ultrasound assessment), and context (swallowing assessment). The review included observational, experimental, descriptive, and analytical studies and excluded those that were not available in full, animal studies, in vitro studies, letters to the editor, errata, study protocols, and those that used ultrasound for purposes other than swallowing. There were no language and time restrictions. Two independent blinded professionals selected 81 articles that met the inclusion criteria from different databases. The most evaluated parameters included tongue morphology and movements, hyoid bone displacement, swallowing muscle area, and pharyngeal residue detection, such as pharyngeal wall mobility. They used convex and linear transducers (3 MHz to 8 MHz) positioned in the submental, laryngeal, and lateral regions of the neck. The subjects were seated and instructed to eat different food volumes and consistencies. The literature mapping showed that ultrasound is a promising diagnostic tool, helping clinicians understand swallowing disorders, as it provides static and dynamic images in different modes and positions. Also, patients receive real-time biofeedback of changes related to dysphagia.

Impact of maximum phonation time on postoperative dysphagia and prognosis after cardiac surgery.

Objective: The incidence of postoperative complications, including dysphagia, increases as the population undergoing cardiovascular surgery ages. This study aimed to explore the potential of maximum phonation time (MPT) as a simple tool for predicting postextubation dysphagia (PED) and major adverse cardiac and cerebrovascular events (MACCEs). Methods: This retrospective study included 442 patients who underwent elective cardiac surgery at a university hospital. MPT was measured before surgery, and patients were stratified into 2 groups based on normal and abnormal MPTs. Postoperative complications, including PED and MACCEs, were also investigated. Swallowing status was assessed using the Food Intake Level Scale. Results: MPT predicted PED with prevalence of 11.0% and 18.0% in the normal and abnormal MPT groups, respectively (P = .01). During the follow-up period, MACCEs developed in 17.0% of patients. Frailty, European System for Cardiac Operative Risk Evaluation II score, PED, and MPT were markedly associated with MACCEs (adjusted hazard ratios: 2.25, 1.08, 1.96, and 0.96, respectively). Mediation analysis revealed that MPT positively influenced PED and MACCEs, whereas PED positively influenced MACCEs. The trend in restricted cubic spline analysis indicated that the hazard ratio for MACCEs increased sharply when MPT was <10 seconds. Conclusions: These findings underscore the potential of MPT as a valuable tool in the preoperative assessment and management of patients undergoing cardiac surgery. By incorporating MPT into routine preoperative evaluations, clinicians can identify patients at a higher risk of PED and MACCEs, allowing for targeted interventions and closer postoperative monitoring. This may improve patient outcomes and reduce the health care costs associated with these complications.

Long-term effects on swallowing and laryngeal function after treatment for severe COVID-19 disease in intensive care.

PURPOSE: This study aimed to assess swallowing and laryngeal function at long-term follow-up in patients treated for severe COVID-19 in the ICU. METHODS: Thirty-six patients with severe COVID-19 were prospectively examined with fiberendoscopic evaluation of swallowing (FEES) about 6 and 12 months after ICU discharge. Comparison with initial FEES examinations during the time in hospital was performed in 17 patients. Analysis of swallowing function and laryngeal features was performed from video recordings. Twenty-five participants responded to Eating Assessment Tool, Voice Handicap Index, and the Hospital Anxiety and Depression Scale at follow-up. RESULTS: Penetration to the laryngeal vestibule (PAS ≥ 3) was seen in 22% and silent aspiration (PAS = 8) in 11% of patients on at least one swallow at follow-up. Fourteen percent had obvious residue in the vallecula and/or pyriform sinuses after swallowing thick liquid or biscuits. Self-reported eating and swallowing difficulties were found in 40% of patients. Abnormal findings in the larynx were present in 53% at follow-up. Thirty-three percent had reduced or impaired vocal fold movement, of whom 22% had bilateral impaired abduction of the vocal folds. Possible anxiety and depression were found in 36% and 24% of responders, respectively. CONCLUSION: Although a majority of patients appear to regain normal swallowing function by 1 year after treatment for severe COVID-19, our results indicate that dysphagia, abnormal laryngeal function, and anxiety/depression may remain in a substantial proportion of patients. This suggests that swallowing and laryngeal function, and emotional symptoms, should be followed up systematically over time in this patient group.

Assessing Dysphagia in the Adult.

This article explores the landscape of dysphagia assessment in adults. Dysphagia, a complex condition affecting the lifespan and many health conditions, significantly compromises individuals' quality of life. Dysphagia is often underdiagnosed, emphasizing the need for comprehensive assessment methods to ensure timely and accurate intervention. It encompasses clinical history, physical examination, clinical and instrumental swallow evaluations. Procedures within each of these modalities are reviewed, highlighting strengths, limitations, and contribution toward a complete understanding of dysphagia, ultimately guiding effective intervention strategies for improved patient outcomes.

Validation of the IDDSI funnel for liquid flow testing.

In 2017, the International Dysphagia Diet Standardisation Initiative (IDDSI) introduced the IDDSI flow test which enables patients, clinicians, caregivers, food service professionals and researchers to classify liquid thickness into five levels based on the volume of liquid remaining in a standard 10 mL slip tip syringe after 10 s of flow under gravity. Within a few months of publishing the IDDSI flow test instructions, several barriers emerged: (1) the preferred model of syringe (BD 303134) was not equally accessible around the world, causing some users to perform flow tests with alternate models of syringe; (2) differences in syringe geometry across models led to variations in IDDSI flow test results; and (3) the need to use a second syringe for sample loading added complexity and cost to end users. To address these barriers, IDDSI designed the IDDSI funnel, a novel device, which combines the geometry of the BD 303134 syringe with a kitchen funnel to facilitate easy loading of liquid samples without need for a second syringe. In this report, we compare the IDDSI flow test results across two devices: syringe BD 303134 and IDDSI funnel. IDDSI level classifications were in complete agreement with the syringe reference test results in 67/73 (92%) of the test fluids and temperature conditions with mean difference of residual liquid across devices of 0.2 (2% full scale). These results demonstrate excellent correspondence between the two devices.

The Impact of Videofluoroscopic Pulse Rate on Duration and Kinematic Measures in Infants and Adults with Feeding and Swallowing Disorders.

This investigation assessed the impact of temporal resolution during a videofluoroscopic evaluation of swallowing (VFSS) on measures of duration and kinematics. Thirty adult and ten infant swallow studies, all acquired at 30 frames and 30 pulses per second, were obtained from a New Mexico hospital. All swallow studies were altered to simulate 15 and 5 pulses per second. Duration measures included pharyngeal response time, duration of upper esophageal sphincter (UES) opening, velopharyngeal closure duration and total swallow duration. Kinematic measures were assessed in adults only and included peak hyoid position and extent of UES opening during the swallow. Analysis of outcome measures was performed and compared across the three temporal resolutions (30, 15, and 5 pulses per second). For data points where normative values are available, we evaluated the impact of temporal resolution on clinical determination (i.e., did a change in pulse rate alter the clinical classification). Kinematic and duration measures were altered with changes in pulse rate and these changes increased as temporal resolution decreased. For outcome measures where normative values are available, accuracy of clinical determination decreased with decreased pulse rate. Temporal resolution impacts duration and kinematic measures. However, the direction of these changes is unpredictable, indicating sensitivity and specificity are both affected. Without a predictable impact, the use of lower pulse rates may alter clinical impressions and treatment recommendations yielding inappropriate treatment goals and treatment duration.

Oropharyngeal dysphagia in children with multiple disabilities.

OBJECTIVE: This study aimed to investigate the prevalence of oropharyngeal dysphagia among institutionalised children with multiple disabilities, a topic with limited literature coverage. METHODS: The study employed a questionnaire, specifically the F-PEDI-EAT-10, to screen for dysphagia in children. Trained nurses administered the questionnaire to the participants. RESULTS: The study included 117 children with multiple disabilities (51.3 per cent boys and 48.7 per cent girls) with an average age of 14 ± 4.7 years. The questionnaire revealed that 53 per cent (n = 62) of the children had a positive score and, surprisingly, 29 per cent of them (n = 18) did not have a confirmed diagnosis of oropharyngeal dysphagia. Notably, children with a positive F-PEDI-EAT-10 score had a significantly higher prevalence of pneumopathy and undernutrition compared with those with a negative score. CONCLUSION: This study underscores the high prevalence of oropharyngeal dysphagia among children with multiple disabilities, a condition that is often underdiagnosed.

Role of fiberoptic endoscopic evaluation of swallowing (FEES) in children with suspected dysphagia.

OBJECTIVE: To assess FEES findings in defining oral feeding safety in children with suspected dysphagia, comparing them with clinical feeding evaluation results. METHODS: This study comprised a case series involving children with suspected dysphagia, referred for evaluation by otolaryngologists and speech-language pathologists (SLPs) at a Brazilian quaternary public university hospital. These children underwent both clinical evaluations and fiberoptic endoscopic evaluation of swallowing (FEES), with a comprehensive collection of demographic and clinical data. Subsequently, the authors performed a comparative analysis of findings from both assessments. RESULTS: Most patients successfully completed the FEES procedure (93.7%), resulting in a final number of 60 cases included in the study. The prevalence of dysphagia was confirmed in a significant 88% of these cases. Suspected aspiration on clinical SLP evaluation was present in 34 patients. Of these, FEES confirmed aspiration or penetration in 28 patients. Among the 35 patients with aspiration or penetration on FEES, 7 (20%) had no suspicion on SLP clinical assessment. All seven patients in whom clinical SLP evaluation failed to predict penetration/aspiration had neurological disorders. The median age of the children was 2.8 years, and 49 (81.6%) had neurological disorders, while 35 (58.3%) had chronic pulmonary disease. The most prevalent complaints were choking (41.6%) and sialorrhea (23.3%). CONCLUSION: FEES can diagnose structural anomalies of the upper aerodigestive tract and significantly contribute to the detection of aspiration and penetration in this group of patients with suspected dysphagia, identifying moderate and severe dysphagia even in cases where clinical assessment had no suspicion.
