Abstract

Assessment of the cricoarytenoideus dorsalis muscle (CAD) in horses using a transesophageal ultrasound, computed tomography, or magnetic resonance imaging is available in a limited number of hospitals. This study assessed the ease of ultrasonographic imaging of the CAD using an external transcutaneous technique in horses. After confirmation of the CAD in the cadavers, ultrasonography in twenty live horses was carried out using a transcutaneous approach. In live horses, ultrasonographic imaging of the CAD was possible by pushing the larynx from the opposite side with the other hand. It is believed that the results of this study may be beneficial in the examination of recurrent laryngeal neuropathy.
