Anatomical changes in the pharynx resulting from changes in head and neck position

TL;DRAbstract

<p>Purpose: The chin down posture is a compensatory strategy commonly used to minimize the risk of aspiration in patients with a pharyngeal delay. There are several difficulties to determining if the chin down posture is effective at eliminating aspiration including: the variability on how to perform the posture, what the posture is called, and the anatomical changes resulting from the posture The main purpose of this study was to determine the anatomical changes associated with different postural positions (i.e., chin down, chin tuck, and head extended) using endoscopy.</p> <p>Method: Twenty healthy female subjects underwent nasoendoscopy and assumed four different head positions with and without a bolus in the oral cavity. Subjects were instructed on how to perform each posture prior to insertion of the endoscope. The four head position included a neutral, chin down (looking at the floor), chin tuck (chin to neck), and head extended position. Still images of each po
