Epiglottic dysfunction: abnormal epiglottic movement patterns.

Abstract

Epiglottic movement patterns of 500 consecutive patients with varying etiologies were recorded during routine videofluoroscopic swallow evaluations. Seven distinct, commonly repeated, abnormal epiglottic patterns were identified. A multifactorial analysis of these seven abnormal epiglottic movement patterns was completed. Findings indicate that each of these seven distinct movement patterns have varying rates and amounts of aspiration. A description of each epiglottic movement pattern is given in conjunction with information regarding aspiration and other variables associated with the swallow process. A universal nomenclature is offered regarding these subtle abnormal epiglottic movement patterns to increase a verbal commonality in our descriptions of epiglottic function as it affects aspiration.
