The cricothyroid artery arises from the superior thyroid artery and may contribute to the supply of the larynx. It follows a variable course either superficial or deep to sternothyroid. If superficial, it may be accompanied by branches of the ansa cervicalis, and if deep, it may be related to the external laryngeal nerve. It can anastomose with the artery of the opposite side and with the laryngeal arteries.
