Swallowing and pharyngo-esophageal manometry in obstructive sleep apnea.

ABSTRACT:

Introduction

Upper airway nerve and muscle damage associated with obstructive sleep apnea may impair the strength and dynamics of pharyngeal and esophageal contractions during swallowing.

Objective

To evaluate the presence of alterations in pharyngoesophageal manometry in patients with obstructive sleep apnea with and without oropharyngeal dysphagia.

Methods

This study prospectively evaluated 22 patients with obstructive sleep apnea without spontaneous complaints of dysphagia, using a questionnaire, fiberoptic endoscopic evaluation of swallowing, and pharyngoesophageal manometry, including measurement of the upper and lower esophageal sphincter pressures and mean pharyngeal pressures at three levels during swallowing.

Results

The dysphagia group consisted of 17
