A stationary coordinate system was established with the cricoid cartilage as a reference and a motion coordinate system was established using the movement of the arytenoid cartilage. The Euler angles of the arytenoid cartilage movement were calculated by transformation of the two coordinate systems, and the spatial motion characteristics of the arytenoid cartilage were quantitatively studied.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Displacement of the cricoid cartilage was primarily inferior during inspiration. During phonation, the displacement was mainly superior. When the glottis closed, the superior displacement was about 5\u20138\u2009mm within 0.56 s. During inspiration, the arytenoid cartilage was displaced superiorly approximately 1\u20132\u2009mm each 0.56 s. The rotation angle was subtle with slight rotation around the XYZ axis, with a range of 5\u201310 degrees. During phonation, the displacement of the arytenoid cartilage was mainly inferior (about 4\u20136\u2009mm), anterior (about 2\u20134\u2009mm) and medial (about 1\u20132\u2009mm). The motion of the arytenoid cartilage mainly consisted of medial rolling, and there was an alternating movement of anterior\u2010posterior tilting. The arytenoid cartilage rolled medially (about 20\u201340 degrees within 0.56 s), accompanied by anterior\u2010posterior tilting (about 15\u201320 degrees within 0.56
