disarticulated with scissors if more exposure
is needed, after which the dorsal
cricoarytenoideus muscle and muscular
process of the arytenoid can be identified.
The dorsal cricoarytenoideus muscle is
grasped with an Allis forceps to aid
disarticulation.

4 The cricoarytenoideus muscle is cut to allow cricoarytenoid disarticulation. The arytenoid is dissected free from
its attachments without entering the laryngeal lumen and the interarytenoid ligament is dissected last.

5 Two synthetic non-absorbable sutures are placed through the most caudodorsal part of the thyroid to the
muscular process of the arytenoid to lateralize the arytenoid. The second suture is placed 5 mm cranial to the first
in the caudal thyroid and 5 mm dorsal through the arytenoid cartilage.
