Computed tomographic anatomy of the larynx in mesaticephalic dogs

The aim of this work was to describe the normal anatomy of the larynx and its adjacent structures in mesaticephalic dogs by computed tomographic (CT) images and correlate those with anatomical sections. For that, 2 clinically normal young-adult mesaticephalic dogs with body weight of 12.8 kg and 18....
