    Introduction

    As typically defined, dysphagia is a condition in which disruption of the swallowing process interferes with a patient’s ability to eat. It can result in aspiration pneumonia, malnutrition, dehydration, weight loss, and airway obstruction. Chest radiography is a simple assessment for pneumonia. The image below shows aspiration of liquid barium into the distal bronchus.

    Pathophysiology

    Aspiration is a term referring to the passive entry of any food item into the trachea (eg, during inhalation), although the word often is used to denote any entry of a bolus into the trachea in any manner. Penetration refers to the active entry of any food item into the trachea (eg, during swallowing), although the term often is used to denote the entry of any bolus into the laryngeal vestibule.
