Ultrasonography of laryngeal abnormalities in small animals allows the identification of laryngeal masses because of the resulting distortion of normal structural/anatomical relationships. It also allows fine-needle aspirates to be taken with minimal risk of causing hemorrhage or edema affecting the already narrowed laryngeal lumen. Findings in six cats and one dog with laryngeal abnormalities are described.
