Abstract.
The purpose of the present study was to investigate the relationship between prevalence of aspiration as determined by videofluoroscopic evaluation and prevalence of the gag reflex and velar movement as determined by direct visual examination. One hundred adult patients underwent a videofluoroscopic evaluation of aspiration with either an esophagram (n = 31), upper gastrointestinal series (n = 18), small bowel series (n = 23), or modified barium swallow procedure (n = 28), and concomitant evaluation of the gag reflex and velar movement on phonation. All studies were performed using the lateral, upright position, and all patients drank at least 5 cc of single contrast barium. Aspiration was defined as penetration of material below the level of the true vocal folds. A normal gag reflex and normal velar movement on phonation were observed in 14 of 15 (93%) patients who exhibited objective documentation of aspiration with videofluoroscopy. Conversely, 19 of 20 (95%) patients without a gag reflex were observed with videofluoroscopy to be without aspiration. Normal velar movement on phonation was observed in 99 of 100 (99%) patients. There was no significant age difference between patients with or without a gag reflex. No relationship was found between the prevalence of aspiration and the gag reflex or velar movement on phonation. It was concluded that the presence of a gag reflex does not protect against aspiration, and the absence of a gag reflex does not predict aspiration.
