Laryngeal artery

Superior thyroid artery

The laryngeal artery refers to the arteries that supply blood to the larynx. There are two main laryngeal arteries: the superior thyroid artery and the inferior thyroid artery.

Superior Laryngeal Artery

The superior laryngeal artery is a branch of the superior thyroid artery. It accompanies the internal laryngeal nerve and supplies the larynx above the vocal cords.

Inferior Laryngeal Artery

The inferior laryngeal artery is a branch of the inferior thyroid artery. It accompanies the recurrent laryngeal nerve and supplies the larynx below the vocal cords.

Function

The laryngeal arteries are crucial for providing oxygenated blood to the larynx, which is essential for its function in voice production and breathing.

Clinical Significance

Damage to the laryngeal arteries can lead to ischemia of the laryngeal tissues, potentially affecting voice and airway function. Surgical procedures involving the thyroid gland or the neck must take care to preserve these arteries to prevent complications.
