Abstract
PurposeTo evaluate the prevalence of dysphagia in survivors of head and neck cancer (sHNC) and to identify the predictors contributing to the development of dysphagia.MethodsWe enrolled 62 sHNC in a cross-sectional study to check the prevalence of dysphagia in sHNC and to evaluate which factors were influencing the presence of this side effect. Besides dysphagia, sociodemographic and clinical characteristics, oral symptoms, maximal mouth opening (MMO), sleep quality and physical condition were evaluated, and a linear regression analysis was performed to verify which of these outcomes impact dysphagia.ResultsAmong all the sHNC, 85.5% presented dysphagia. The linear regression analysis confirmed that 44.9% of the variance in dysphagia was determined by coughing, MMO and sleep quality, being MMO the most powerful predictor, followed by coughing and sleep quality.ConclusionDysphagia affected the great majority of sHNC. Moreover, symptoms as coughing, reduced MMO and sleep disorders may act as predictors contributing to the development of dysphagia. Our results emphasize the importance of an early and proper identification of the symptoms as well as an adequate treatment strategy to address the cluster of symptoms that sHNC undergo.
