Título

Evaluation of Swallowing in Obstructive Sleep Apnea

Introdução

Obstructive Sleep Apnea (OSA) may cause neuro / myopathy in the pharyngeal muscles of affected patients. Such alterations can lead to dysfunction in the swallowing process, since the reflex evocation and the spread of the bolus are dependent on adequate pharyngeal sensitivity and function. In most cases, however, the complaint of dysphagia is not mentioned spontaneously by OSA patients.

Objetivo

To evaluate swallowing disorders in OSA through the Swallowing Video Endoscopy (VED) exam in asymptomatic patients.

Métodos

Twelve patients with snoring (older than 18 years), diagnosed with OSA by polysomnography, underwent VED.

Resultados

The examination showed alteration in 8 patients (66.6%). The following alterations were found in the studied sample: 8 patients (66.6%) presented early bolus escape; 5 patients (41.6%), laryngeal penetration and 2 patients (16.6%), residue formation. All were referred for speech therapy treatment.

Conclusões

Alterations in the swallowing process are frequent in this patient population, even in asymptomatic patients. Larger and controlled studies should be performed to better evaluate this finding. Thus, screening at risk patients can be considered for speech therapy referral and prevention of future symptoms.
