Peer Review Status: Internally Peer Reviewed


An occasional band of muscle may be found in contact with the lower border of the posterior cricoarytenoid. The ceratocricoideus (of Merkle) (or keratocricoid) is a short muscle arising near the lower border of cricoid cartilage, a little behind the inferior cornu of the thyroid cartilage, and passing obliquely outward and upward to be inserted into the inferior cornu of the thyroid cartilage. This variation was found in seven of 32 (21.9%) bodies studied and it usually exists on one side of the body only. According to Hetherington, the incidence of this variation is actually about 17%.
