Prevalence of dysphagia in patients with muscle tension dysphonia

Abstract

BackgroundIt is hypothesised that patients with muscle tension dysphonia have a high prevalence of dysphagia in comparison to normative values reported in the literature.MethodsThis prospective study included 44 subjects diagnosed with muscle tension dysphonia, based on symptoms and laryngoscopic findings, and 25 control subjects with no history of dysphonia and normal laryngeal examination findings. Demographic data included age, gender and smoking history. The aetiology of muscle tension dysphonia was classified as primary or secondary. Evaluation involved the Eating Assessment Tool (‘EAT-10’) questionnaire.ResultsPatients’ mean age was 45.93 ± 14.95 years, with a female to male ratio of 1.2:1. Fourteen patients had primary muscle tension dysphonia, while 30 had secondary muscle tension dysphonia. Among patients with secondary muscle tension dysphonia, Reinke's oedema was the most common aetiology. There was a significant difference in the prevalence of dysphagia between the study group and the control group (40.9 per cent vs 8 per cent respectively, p < 0.05).ConclusionThis study demonstrates a higher prevalence of dysphagia in patients with the presenting symptom of dysphonia and diagnosed with muscle tension dysphonia in comparison to subjects with no dysphonia.

Disfonía por tensión muscular: concepto y criterios diagnósticos

“…De los 15 artículos restantes, tres se refieren a la necesidad de realizar más exploración instrumentada y una adecuada historia clínica para llegar a un oportuno diagnóstico. Dos estudios refieren mayor patología en mujeres que en hombres [5,9]; cuatro reportan presión subglótica aumentada (>90 mmHg) [10][11][12][13] y tres reportan medidas fonatorias [12][13][14]: uno encuentra diferencias significativas [12] y dos refieren solo el pico cepstral como referencia confiable y con mayor predictibilidad diagnóstica [13,14]. Un trabajo propone el video de alta resolución como demostración de hiperfunción vocal [15].…”

“…Un trabajo que evaluó 44 pacientes con diagnóstico de MTD por hallazgos laringoscópicos, reportó que la edad media de los pacientes fue de 45,93 ± 14,95 años, con una relación mujer/hombre de 1.2:1. Entonces, la presentación es mayor en adultos de más de 30 años y ligeramente mayor en mujeres [5]. El estudio de Benninger et al con población de Estados Unidos de América, evalúo 146,7 millones de personas, entre 2008 a 2012, estimando la prevalencia de disfonía para 2008 de 760,265 casos y para 2012 de 1,247,471, con aumento del 1.3 % al 1.7 %, en estos años [6].…”

“…Los instrumentales pueden ser diversos, entre los que se encuentran: videolaringoscopia, radiografía, electromiografía y resonancia magnética funcional. Otros métodos pueden ser electroglotográficas, acústicas y aerodinámicas [5,8].…”

A retrospective study of patients presenting with speech and language therapy needs within multidisciplinary Long COVID services: A service evaluation describing and comparing two cohorts across two NHS Trusts

“…Given our knowledge of other symptoms of Long COVID, dysphagia symptoms may be driven by other factors such as laryngeal hypersensitivity, reflux, post‐extubation dysphagia, muscle tension dysphagia, fatigue and breathlessness (Buckley et al., 2021; Frajkova et al., 2020; Hamdan et al., 2019; Kruser & Prescott, 2017). During the period under study in East Suffolk, access to SLT‐led videonasendoscopy and FEES was limited by the emergence of COVID recovery planning, and implementation of changing professional guidance (RCSLT, 2021b) to facilitate the resumption of clinics.…”

Muscle Tension Dysphagia: Contributing Factors and Treatment Efficacy

“…[45][46][47][48][49][50][51] Since dysphagia is a known association of muscle tension dysphonia, we postulated that the same therapeutic techniques would be beneficial for a subset of dysphagia patients. 52,53 Our MTDg retrospective study revealed that voice therapy techniques aimed at reducing laryngeal muscle tension significantly reduced dysphagia symptoms. The same therapy techniques were then employed in this perspective study with promising results.…”
