Studies for Evaluation of Aspiration
Studies for Aspiration Evaluation:
These evaluations are performed in children suspected of aspirating food or saliva into their windpipe, a condition often seen in those with neurological conditions such as cerebral palsy, neurodegenerative diseases, or neuromuscular disorders. Aspiration can lead to repeated episodes of pneumonia and, ultimately, lung damage. These studies help document aspiration and guide appropriate management plans.
Video-Fluoroscopic Swallow Study (VFSS):
Also known as a Modified Barium Swallow (MBS), the VFSS uses fluoroscopy to observe swallowing. During the study, food mixed with barium is administered in various consistencies according to a set protocol. The sequence typically includes thin liquids (e.g., milk), thickened liquids (e.g., thick juice), puree, and solid foods, based on the child’s tolerance. This allows us to observe if food enters the windpipe during swallowing. At our hospital, pediatric pulmonologists and radiologists jointly perform these studies to ensure accuracy.
Fiberoptic Endoscopic Evaluation of Swallowing (FEES)
The Fiberoptic Endoscopic Evaluation of Swallowing (FEES) assesses the pharyngeal phase of swallowing, aiming to detect aspiration and determine safe dietary options for the child. In this study, a thin, flexible bronchoscope or laryngoscope is gently passed through the nose to the hypopharynx, allowing visualization of the glottis and vocal cords. The child sits in an optimal feeding position and is offered foods of varying consistencies, as in a VFSS, but without barium. The procedure is conducted live, and the results are recorded.
