Thyrohyoid ligament

Thyrohyoid Ligament

The Thyrohyoid ligament is a significant anatomical structure in the human body, specifically within the neck region. It is part of the laryngeal framework and plays a crucial role in the functioning of the voice box or larynx.

Anatomy

The thyrohyoid ligament is a broad, fibrous band that connects the thyroid cartilage to the hyoid bone. It is composed of two parts: the median thyrohyoid ligament and the lateral thyrohyoid ligament. The median thyrohyoid ligament is a thick, unpaired structure, while the lateral thyrohyoid ligament is thinner and paired.

Function

The primary function of the thyrohyoid ligament is to stabilize the position of the larynx in the neck. It allows for the movement of the larynx during swallowing and phonation, while ensuring that the larynx maintains its position relative to the hyoid bone.

Clinical Significance

The thyrohyoid ligament can be involved in various medical conditions. For instance, injury to the ligament can result in voice disorders due to the disruption of laryngeal function. Additionally, the ligament can be a site of calcification in certain pathological conditions, which can lead to difficulty in swallowing or breathing.
