Straw vs Cup Use in Patients with Symptoms of Oropharyngeal Dysphagia.

Context: This study aims to determine whether straw or cup use is superior for the control of a single thin liquid bolus in patients with symptoms of oropharyngeal dysphagia to liquids.

Methods: This is a prospective, randomized, single-blinded study. Patients were studied at a Professional Voice and Swallowing Center by a laryngologist between April 2017 and April 2018. Twenty-five patients, 18 years of age or older, who presented with symptoms of oropharyngeal dysphagia the clinic were included in the study. Each patient complained of difficulty with choking on liquids. Informed consent was obtained from each patient. Patients that were unable to follow one to two step commands and patients with dysphagia that lack oral strength or respiratory strength to facilitate straw or cup usage were not included. Patients with dysphagia that are tracheostomy tube dependent were also not included.

Results: The average PAS for straw versus cup drinking at 10mL was 1.08 and 1.04 respectively with a p-value of 0.33. For straw versus cup at 20mL, the PAS was 1.04 and 1.26 respectively with a p-value of 0.13. For 30mL, the PAS was 1.0 and 1.4 for straw and cup use respectively with a p-value of 0.16. And for 40mL, the PAS was 1.0 and 1.09 with a p-value of 0.27.

Conclusions: No statistical significant difference was demonstrated in risk of penetration or aspiration of thin liquids between cup and straw usage in patients with mild oropharyngeal dysphagia.
