ABSTRACT

OBJECTIVE/HYPOTHESIS: Adenotonsillar problems might affect the voices of patients with pediatric dysphonia, which is very common. This study aimed to evaluate the prevalence of dysphonia in patients with adenotonsillar problems and to demonstrate the impact of tonsillectomy and adenoidectomy (T & A) on their voice postoperatively. STUDY DESIGN: Single-institution retrospective study. METHODS: Subjects were recruited from those children admitted for the purpose of T & A, and all underwent the auditory-perceptual assessment by speech therapists preoperatively. If children demonstrated scores >2 in the G parameter, we performed subjective (pediatric voice handicap index [pVHI], severity, talkativeness scale) and objective (Multi-Dimensional Voice Program) voice analyses preoperatively and 1 and 3 months postoperatively. RESULTS: Among the 1,197 patients, 91 (7.6%) patients showed dysphonia with a score >2 in the G parameter preoperatively. The follow-up voice analysis was completed in 51 and 22 patients after 1 and 3 months, respectively. Although there were no significant differences in the amount of speech preoperatively and postoperatively, the average visual analog scale score for dysphonia severity was significantly decreased at postoperative 1 month and postoperative 3 months. The average total pVHI score, jitter, shimmer, noise-to-harmonic ratio, and soft phonation index were significantly decreased at 1 and 3 months postoperatively. Subjective scores given by parents did not correlate with the acoustic parameters; however, the postoperative subjective parameters were significantly correlated with objective parameters. CONCLUSIONS: Voice problems were significantly improved after T & A in the short term and long term. In those with pediatric dysphonia, decreased mouth breathing and compliance with vocal hygiene would be helpful for voice improvement. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:2369-2375, 2021.

ABSTRACT

PURPOSE: This study aimed to investigate pharyngeal paraesthesia symptoms in patients with obstructive sleep apnoea (OSA). MATERIAL AND METHODS: Patients with snoring and suspected OSA as well as age-matched controls were recruited. All participants underwent nocturnal polysomnography (PSG) and pharyngeal paraesthesia assessment using the Glasgow-Edinburgh throat scale (GETS). The incidence and severity of pharyngeal paraesthesia symptoms were compared between the groups. RESULTS: A total of 280 patients who snored or were suspected of having OSA and 35 healthy, age-matched controls were recruited. The total pharyngeal paraesthesia symptom score was significantly higher in the OSA group than in the healthy group (12 [5, 23] vs. 3 [0, 9]; p < 0.001). The most frequent pharyngeal paraesthesia symptoms in the snore patients were Q7 (catarrh down the throat) and Q3 (discomfort/irritation in the throat), which are related to the irritability of the throat. The incidence of Q7 (OSA, 58% vs. controls, 14%; χ2 = 23.66; p < 0.001), Q3 (OSA, 46% vs. controls, 3%; χ2 = 23.07; p < 0.001), Q1 (feeling of something stuck in the throat; OSA, 33% vs. controls, 6%; χ2 = 11.00; p = 0.001), Q6 (swelling in the throat; OSA, 31% vs. controls, 0%; χ2 = 14.53; p < 0.001), Q9 (want to swallow all the time; OSA, 20% vs. controls, 6%; χ2 = 6.28; p = 0.012), Q5 (throat closing off; OSA, 24% vs. controls, 6%; χ2 = 6.16; p = 0.013), and Q2 (pain in the throat; OSA, 23% vs. controls, 6%; χ2 = 5.32; p = 0.021) was significantly higher in the OSA group than in the controls CONCLUSIONS: Patients with obstructive sleep apnoea have higher pharyngeal paraesthesia symptoms scores and tend to have irritated throats compared to healthy controls.

ABSTRACT

ANTECEDENTES Y OBJETIVO: Las técnicas quirúrgicas para tratar el colapso velofaríngeo de los pacientes con síndrome de apnea-hipopnea del sueño han evolucionado en los últimos años. Nuestro objetivo era conocer si estas nuevas técnicas proporcionan mejores resultados quirúrgicos. MATERIALES Y MÉTODOS: Es un estudio retrospectivo de los pacientes con síndrome de apnea-hipopnea del sueño moderado-severo tratados quirúrgicamente del 2006 al 2018. Solo los pacientes adultos sin adherencia a la CPAP y en los que no se practicó cirugía multinivel simultánea fueron incluidos. Durante este período se practicaron 4 técnicas diferentes: resección parcial del paladar, faringoplastia lateral, faringoplastia de expansión y faringoplastia de reposición con sutura barbada. La tasa de éxito se calcula según los criterios de Sher, según el criterio de IAH < 10/h y mediante la reducción relativa media del IAH (RRM). RESULTADOS: Ochenta y dos pacientes fueron incluidos. El IAH se redujo significativamente de 43,4 ± 24/h a 15,6 ± 18,6/h. No se observaron cambios significativos en el índice de masa corporal. Los valores de Tc 90, el índice de desaturación y la somnolencia según la escala de Epworth mejoraron tras la cirugía. La mayor tasa de éxito se obtuvo mediante la realización de la faringoplastia de reposición con sutura barbada (78,26% según criterios Sher, 65,22% para IAH < 10/h y 74,1% en RRM). Las diferencias observadas fueron estadísticamente significativas. CONCLUSIONES: La faringoplastia de reposición con sutura barbada es una técnica de reciente introducción que mostró superioridad sobre el resto de faringoplastias en esta cohorte


BACKGROUND AND PURPOSE: The surgical techniques used to treat velopharyngeal collapse in obstructive sleep apnoea patients have evolved over recent years. Our aim was to determine whether these new techniques have better surgical results. MATERIALS AND METHODS: This is a retrospective study of moderate to severe obstructive sleep apnoea patients surgically treated from 2006 to 2018. Only adult patients with no compliance to positive airway pressure and without simultaneous multilevel surgery were included. During this period, 4 different techniques were performed: uvulopalatopharyngoplasty, lateral pharyngoplasty, expansion pharyngoplasty and barbed reposition pharyngoplasty. Success rates as defined by Sher, as well as postoperative AHI < 10/h and mean relative AHI reduction (MRR) were compared. RESULTS: 82 patients were included. AHI was significantly reduced from 43.4 ± 24/h to 15.6 ± 18.6/h. No significant changes in body mass index were observed. Hypoxaemia time, oxygen desaturation index, and Epworth sleepiness scale values improved after surgery. The best success rates were obtained performing barbed reposition pharyngoplasty (78.26% measured by Sher's criteria, 65.22% by AHI < 10/h criteria and 74.1% by the MRR). The differences observed were statistically significant. CONCLUSIONS: Barbed reposition pharyngoplasty is a recently introduced technique that showed superiority over the other palatal surgery techniques in this cohort

ABSTRACT

The diagnosis of atypical paroxysmal events represents a significant challenge for clinicians when differentiating epileptic from nonepileptic events. The ictal manifestations of pharyngeal dysesthesias are often misdiagnosed and difficult to distinguish clinically, given their subtle features such as pharyngeal discomfort with and without autonomic symptomology. We report a rare case of isolated ictal pharyngeal dysesthesias localizing to the non-dominant frontal operculum lobe misdiagnosed as psychogenic and later confirmed by continuous video-EEG monitoring.

ABSTRACT

INTRODUCTION: The pathophysiology of dysphagia in Parkinson's disease (PD) is heterogeneous and poorly understood at present. This study investigated the phenotypes, prevalence and pathophysiology of oropharyngeal freezing (OPF) in PD and its relation to dysphagia. METHODS: In a prospective study, 50 PD patients were systematically screened for OPF using flexible endoscopic evaluation of swallowing (FEES). In addition, FEES-videos of 50 patients with post-stroke dysphagia and 50 healthy subjects were retrospectively evaluated as control groups. In PD patients freezing was assessed with the "freezing of gait (FoG) questionnaire" and the relationship between OPF and FoG was analyzed. RESULTS: In analogy to FoG, signs for OPF presented as either temporarily missing or delayed swallowing reflex in combination with freezing associated movement abnormalities e.g. festination, trembling, or akinesia. Seventeen PD patients (34%) showed considerable signs for OPF (15 cases of festination, 3 cases of trembling, 3 cases of akinesia). In the patients with post-stroke dysphagia, OPF was detected in 2 patients (4%). The healthy subjects showed no signs for OPF. The distribution of OPF differed significantly between the investigated groups (p < 0.01). PD patients with signs for OPF scored significantly higher in the FoG-questionnaire (12.69 ± 6.37) compared to patients without OPF (7.29 ± 5.17; p < 0.01). CONCLUSION: Swallowing in PD patients can be impaired by OPF. We suggest that OPF and FoG share common pathophysiologic mechanisms based on their association and similar semiologies.

ABSTRACT

OBJECTIVE: The 2008 diagnostic criteria classify Multiple System Atrophy (MSA) patients in a predominantly parkinsonian (MSA-P) or cerebellar (MSA-C) type. Phenotypic descriptions have since highlighted a clinical heterogeneity among patients (e.g., mixed-type, cognitive impairment, atypical longer survival). This study attempts to identify different phenotypes of patients with MSA and to describe corresponding brain 18-FDG Positron Emission Tomography (PET) patterns. METHODS: Patients with a "probable" MSA diagnosis for whom a brain 18-FDG PET was performed were included. A retrospective analysis (from 2006 to 2017) was conducted using standardized data collection. We used Latent Class Analysis (LCA), an innovative statistical approach, to identify profiles of patients based on common clinical characteristics. Brain metabolism of different groups was studied at rest. RESULTS: Eighty-five patients were included. Three different profiles were revealed (entropy = 0.835): 1. extrapyramidal, axial, laryngeal-pharyngeal involvement (LPI) and cerebellar symptoms (n = 46, 54.1%); 2. cerebellar and LPI symptoms (n = 30, 35.3%); 3. cerebellar and cognitive symptoms (n = 9, 10.6%). Brain metabolism analyses (k > 89; p < 0.001) showed hypometabolism of the basal ganglia, frontal/prefrontal, temporal cortices and left posterior cerebellum in profile 1. In profile 2 there was hypometabolism of the medulla, prefrontal, temporal, cingular cortices, putamen and bilateral cerebellar hemispheres. In profile 3 there was hypometabolism of bilateral posterior cerebellar hemispheres and vermis. CONCLUSION: Beyond the two most common phenotypes of MSA, a third and particularly atypical profile with cerebellar and cognitive symptoms but without LPI involvement is described. These profiles are supported by different brain metabolic abnormalities which could be useful for diagnostic purposes.

ABSTRACT

OBJECTIVE: To compare the frequency and type of diagnoses associated with pharyngeal dysfunction (PD) in children presenting with early versus late onset sleep disordered breathing (SDB). METHODS: This was a retrospective, cross-sectional study. A consecutive series of children ≤3 years old who underwent management for SDB were retrospectively identified from a prospectively kept surgical database. The early onset group was compared with two separate late onset (≥4years old) groups. Diagnoses associated with PD included gastroesophageal reflux disease (GERD), swallowing dysfunction, prematurity, asthma, and obesity. Distribution of PD diagnoses, airway lesions, syndromic conditions, pulse oximetry scores, and endoscopic pattern of airway obstruction were compared. RESULTS: 73 patients with early onset SDB were identified (51 boys, mean age 2.25 ±â€¯0.64 years, range 1.75-3 years) and compared with two groups of later onset SDB consisting of 75 and 72 patients with mean ages of 7.58 ±â€¯2.40 years and 8.04 ±â€¯3.34 years respectively (range 4-16 years). The early onset SDB group had a higher prevalence of PD diagnoses compared to the later onset group with 35 of 73 patients being diagnosed compared to 41 of 147 children (p = 0.01). Early onset SDB patients were more likely to have GERD or swallowing dysfunction (p < 0.01) while later onset patients more commonly presented with associated asthma or obesity (p < 0.01). There was no statistically significant difference in airway lesions between groups. CONCLUSION: Early-onset SDB is associated with conditions causing PD more often than later-onset SDB. Identifying these conditions and optimizing their management may impact outcomes in treating pediatric SDB.

ABSTRACT

OBJECTIVE: To determine whether airway narrowing during obstructive events occurs predominantly at the retropalatal level and results from dynamic changes in the lateral pharyngeal walls and in tongue position. METHODS: We evaluated 11 patients with severe obstructive sleep apnea (OSA) and 7 healthy controls without OSA during wakefulness and during natural sleep (documented by full polysomnography). Using fast multidetector CT, we obtained images of the upper airway in the waking and sleep states. RESULTS: Upper airway narrowing during sleep was significantly greater at the retropalatal level than at the retroglossal level in the OSA group (p < 0.001) and in the control group (p < 0.05). The retropalatal airway volume was smaller in the OSA group than in the control group during wakefulness (p < 0.05) and decreased significantly from wakefulness to sleep only among the OSA group subjects. Retropalatal pharyngeal narrowing was attributed to reductions in the anteroposterior diameter (p = 0.001) and lateral diameter (p = 0.006), which correlated with an increase in lateral pharyngeal wall volume (p = 0.001) and posterior displacement of the tongue (p = 0.001), respectively. Retroglossal pharyngeal narrowing during sleep did not occur in the OSA group subjects. CONCLUSIONS: In patients with OSA, upper airway narrowing during sleep occurs predominantly at the retropalatal level, affecting the anteroposterior and lateral dimensions, being associated with lateral pharyngeal wall enlargement and posterior tongue displacement.

ABSTRACT

Objectives: To analyze the relationship between pharyngeal response time (PRT) and lateralization of brain lesions. Methods: A Cross-sectional study. 73 videofluoroscopic swallow studies (VFSS)were conducted on patients after stroke The study subjects were divided into : group 1 (G1) consisting of 39 individuals with left cortical lesion and group 2 (G2) consisting of 34 individuals with right cortical lesions. The VFSS of G1 and G2 subjects were analyzed using puree (A) and liquid (B) consistencies, and  were also subdivided into young adults and older persons. . The mean PRT was divided into times shorter and longer than 250 ms. Results: No statistically significant difference was observed between G1 and G2 for the A and B consistencies, being obtained : G1 (A mean: 56.6 ms; B mean: 99.5 ms; A mean: 3627 ms; B mean: 1712 ms) and G2 (A mean: 79.6 ms; B mean: 110.7 ms; A mean: 2040 ms, B mean: 1529 ms), for PRT shorter (A:p = .673; B: p = 1.000) and longer (A: p = .435; B: p = .847) than 250 ms, respectively. No statistically significant difference was found regarding the variable age in the comparison between young and old adults for mean PRT according to the A and B consistencies in G1 (A: p = .260; B: p = .732) and G2 (A: p = .586; B: p = .104). Conclusion: No relationship between PRT and lateralization of brain lesion was observed with respect to subject age and to the swallowing of different food consistencies.

ABSTRACT

Mutations in the Matrin 3 (MATR3) gene have been identified as a cause of amyotrophic lateral sclerosis (ALS) or vocal cord and pharyngeal weakness with distal myopathy (VCPDM). This study investigated the mechanism by which mutant MATR3 causes multisystem proteinopathy (MSP) including ALS and VCPDM. We first analyzed the muscle pathology of C57BL/6 mice injected with adeno-associated viruses expressing human WT or mutant (S85C) MATR3. We next generated transgenic mice that overexpress mutant (S85C) MATR3, driven by the CMV early enhancer/chicken ß-actin promoter, and evaluated their clinicopathological features. Intramuscular injection of viruses expressing WT and mutant MATR3 induced similar myogenic changes, including smaller myofibers with internal nuclei, and upregulated p62 and LC3-II. Mutant MATR3 transgenic mice showed decreased body weight and lower motor activity. Muscle histology demonstrated myopathic changes including fiber-size variation, internal nuclei and rimmed vacuoles. Spinal cord histology showed a reduced number of motor neurons, and activation of microglia and astrocytes. Comprehensive proteomic analyses of muscle demonstrated upregulation of proteins related to chaperones, stress response, protein degradation, and nuclear function. Overexpression of WT and mutant MATR3 similarly caused myotoxicity, recapitulating the clinicopathological features of MSP. These models will be helpful for analyzing MSP pathogenesis and for understanding the function of MATR3. © 2019 Pathological Society of Great Britain and Ireland.

ABSTRACT

RATIONALE AND OBJECTIVES: Non-invasive quantification of the severity of pharyngeal airflow obstruction would enable recognition of obstructive versus central manifestation of sleep apnoea, and identification of symptomatic individuals with severe airflow obstruction despite a low apnoea-hypopnoea index (AHI). Here we provide a novel method that uses simple airflow-versus-time ("shape") features from individual breaths on an overnight sleep study to automatically and non-invasively quantify the severity of airflow obstruction without oesophageal catheterisation. METHODS: 41 individuals with suspected/diagnosed obstructive sleep apnoea (AHI range 0-91 events·h-1) underwent overnight polysomnography with gold-standard measures of airflow (oronasal pneumotach: "flow") and ventilatory drive (calibrated intraoesophageal diaphragm electromyogram: "drive"). Obstruction severity was defined as a continuous variable (flow:drive ratio). Multivariable regression used airflow shape features (inspiratory/expiratory timing, flatness, scooping, fluttering) to estimate flow:drive ratio in 136 264 breaths (performance based on leave-one-patient-out cross-validation). Analysis was repeated using simultaneous nasal pressure recordings in a subset (n=17). RESULTS: Gold-standard obstruction severity (flow:drive ratio) varied widely across individuals independently of AHI. A multivariable model (25 features) estimated obstruction severity breath-by-breath (R2=0.58 versus gold-standard, p<0.00001; mean absolute error 22%) and the median obstruction severity across individual patients (R2=0.69, p<0.00001; error 10%). Similar performance was achieved using nasal pressure. CONCLUSIONS: The severity of pharyngeal obstruction can be quantified non-invasively using readily available airflow shape information. Our work overcomes a major hurdle necessary for the recognition and phenotyping of patients with obstructive sleep disordered breathing.

ABSTRACT

The aim of this study was to assess pharyngeal swallowing impairments in thyroidectomy patients and to delineate the contributory kinematic components. Forty consecutive patients (mean age = 47.33 years) and fourteen age- and sex-matched heathy adult volunteers (mean age = 42.64 years) participated in this study. A videofluoroscopic swallowing study (VFSS) was performed 1 day prior to surgery, and at 1 week and 3 months post-surgery. VFSS images were evaluated using the Modified Barium Swallowing Impairment Profile (MBSImp). Kinematic and temporal aspects of swallowing were characterized by measurement of maximum hyoid and laryngeal excursion, pharyngeal transit duration, laryngeal response duration (LRD), and laryngeal closure duration at each three time-points. At 1 week post-surgery, only pharyngeal impairment was significantly deteriorated than pre-surgery (p = 0.001). However, at 3 months, a significant improvement was observed to pre-surgery level (p = 0.01). Post-surgery, maximum hyoid excursion was significantly reduced in patients compared controls (p = 0.001). Although the maximal distance of the hyoid and the laryngeal excursion was shorter than before surgery, laryngeal excursion at all three time-points was similar to that of controls. At all three time-points, LRD was significantly longer in patients than in controls (p = 0.01). Following thyroidectomy, pharyngeal aspects of swallowing as measured by the MBSImp and kinematic aspects of swallowing were reduced with incomplete recovery at 3 months. These exploratory data may guide decision regarding management of pharyngeal swallowing impairment with patients undergoing total thyroidectomy.

Resumo Objetivo: Determinar se o estreitamento das vias aéreas durante eventos obstrutivos ocorre predominantemente na região retropalatal e resulta de alterações dinâmicas nas paredes laterais da faringe e na posição da língua. Métodos: Avaliamos 11 pacientes com apneia obstrutiva do sono (AOS) grave (grupo AOS) e 7 indivíduos saudáveis sem AOS (grupo controle) durante a vigília e o sono natural (documentado por meio de polissonografia completa). Por meio de TC multidetectores rápida, obtivemos imagens das vias aéreas superiores no estado de vigília e de sono. Resultados: O estreitamento das vias aéreas superiores durante o sono foi significativamente maior na região retropalatal do que na região retrolingual no grupo AOS (p < 0,001) e no grupo controle (p < 0,05). O volume da via aérea retropalatal foi menor no grupo AOS do que no grupo controle durante a vigília (p < 0,05) e diminuiu significativamente da vigília ao sono apenas no grupo AOS. O estreitamento retropalatal da faringe foi atribuído à redução do diâmetro anteroposterior (p = 0,001) e lateral (p = 0,006), que se correlacionou com o aumento do volume das paredes laterais da faringe (p = 0,001) e o deslocamento posterior da língua (p = 0,001). Não ocorreu estreitamento retrolingual da faringe durante o sono no grupo AOS. Conclusões: Em pacientes com AOS, o estreitamento das vias aéreas superiores durante o sono ocorre predominantemente na região retropalatal e afeta as dimensões anteroposterior e lateral, além de estar relacionado com aumento das paredes laterais da faringe e deslocamento posterior da língua.

ABSTRACT

Ear, nose and throat (ENT) comorbidities are common in patients with asthma and are frequently associated with poorer asthma outcomes. All these comorbidities are "treatable traits" in asthma. Identification and management of these disorders may spare medication usage and contribute to improved asthma control and quality of life, and a decrease in exacerbation rates.This review summarises recent data about the prevalence, clinical impact and treatment effects of ENT comorbidities in asthma including allergic rhinitis, chronic rhinosinusitis with and without nasal polyposis, aspirin-exacerbated respiratory disease, obstructive sleep apnoea and vocal cord dysfunction.Many of these comorbidities are possible to be managed by the pulmonologist, but the collaboration with the ENT specialist is essential for patients with chronic rhinosinusitis or vocal cord dysfunction. Further rigorous research is needed to study the efficacy of comorbidity treatment to improve asthma outcomes, in particular with the development of biotherapies in severe asthma that can also be beneficial in some ENT diseases.

ABSTRACT

BACKGROUND: Cricopharyngeus muscle dysfunction (CPMD) is a common cause of dysphagia. We employ a progressive series of three double-balloon dilations separated by 4-6 weeks between procedures as a primary treatment option. The purpose of this study was to evaluate subjective, functional and objective improvement in swallowing after three serial dilations for CPMD. METHODS: We retrospectively evaluated patients between June 1, 2014, and June 30, 2016, who underwent a series of three double-balloon dilations for CPMD. Pre- and post-dilation Eating Assessment Tool-10 (EAT-10), Functional Oral Intake Scale (FOIS), pharyngeal constriction ratio, pharyngeal area, and pharyngoesophageal segment (PES) opening were compared. RESULTS: Seventeen patients with CPMD underwent serial double-balloon dilation procedures separated by one month. Mean age of the cohort was 73.5 (SD ± 13.3) years, and 53% were female. The mean EAT-10 improved from 24.7 (SD ± 7.8) to 15.9 (SD ± 10.2) [p = 0.0021]. Mean FOIS improved from 5.4 (SD ± 1.4) pre- to 6.3 (SD ± 0.9) post-treatment (p = 0.017). Mean UES opening increased from 1.05 (SD ± 0.34) cm to 1.48 (SD ± 0.41) cm (p = 0.0003) in the anteroposterior fluoroscopic view and from 0.58 (SD ± 0.18) to 0.76 (SD ± 0.30) cm (p = 0.018) in the lateral view. Pharyngeal constriction ratio (PCR), a surrogate measure of pharyngeal strength, improved from 0.49 (SD ± 0.37) to 0.24 (SD ± 0.15) (p = 0.015), however pharyngeal area (PA) was unchanged. CONCLUSIONS: A progressive series of three double-balloon dilations for cricopharyngeus muscle dysfunction resulted in improved patient reported dysphagia symptom scores and objective fluoroscopic swallowing parameters.
