The Median thyrohyoid ligament is a fibrous cord that connects the thyroid cartilage to the hyoid bone. It is a part of the laryngeal framework and plays a crucial role in the functioning of the larynx and vocal cords.

Anatomy

The median thyrohyoid ligament is located in the anterior midline of the neck. It extends from the upper border of the thyroid cartilage to the hyoid bone. The ligament is covered by the thyrohyoid membrane, which is a broad, fibrous sheet that connects the thyroid cartilage and hyoid bone.

Function

The primary function of the median thyrohyoid ligament is to stabilize the position of the larynx in the neck. It helps to maintain the alignment of the larynx and prevent its displacement. The ligament also plays a role in the movement of the larynx during swallowing and speech.

Clinical significance

Injuries to the median thyrohyoid ligament can result in voice changes, difficulty swallowing, and pain in the neck. These injuries can occur due to trauma, surgery, or diseases such as cancer.
