Purpose: The goal of this article was to assess the utility of thickened liquids for patients with oropharyngeal dysphagia. Conclusion: The use of thickened liquids is pervasive, but clinical justification and understanding varies widely among practitioners of deglutition. The benefit of diet/liquid recommendations and other compensatory strategies should be validated via instrumental examination. As highlighted in this review, thickening of liquids may pose serious implications and consequences for both a patient's physical welfare and quality of life. Careful patient selection is recommended to ensure the expected benefits from liquid thickeners outweigh the risks.
