Fig. 2. Ultrasonographic assessment of thyroid-hyoid approximation. The transducer is positioned at the midsagittal plane of the anterior neck, between the thyroid cartilage (Tc) and the hyoid bone (Hy). Sonogra-phic imaging demonstrates the mea-surement of the distance between the thyroid cartilage and hyoid bone at the resting position (A) and at maximal approximation (B).
