Relação do Tempo Máximo de Fonação em Pacientes com Disfagia Secundária a Acidente Vascular Cerebral

Abstract

In stroke patients dysphagia is a higher incidence of complications and may result in aspiration pneumonia. Objective. To relate the value of the maximum phonation time (MPT) in the vowel / e / sustained in patients with neurogenic dysphagia and the presence of tracheal aspiration. Method. We studied 38 adult patients, 22 (57.9%) males and 16 (48.1%) females, from 40 to 85 years. They were divided into groups smaller than 10s and above or equal to 10s. We used values of TMF in vowel / e / open sustained compared with endoscopic examination findings swallowing. Results. The ratio of the MPT vowel / e / sustained in patients with neurogenic dysphagia secondary to stroke, showed no statistical significance for the presence of tracheal aspiration. Conclusion. The reduced TMF does not mean the presence of tracheal aspiration, rendering ineffective its use in clinical practice. Further studies are needed to define security parameters in the evaluation of patients with stroke and neurogenic dysphagia.
