Thyrohyoid muscle atrophy refers to the wasting away or weakening of the thyrohyoid muscle. This muscle, located in the anterior neck, connects the thyroid cartilage to the hyoid bone and plays a vital role in swallowing and stabilizing the larynx. When this muscle loses mass or strength, it can contribute to various symptoms and impair daily activities such as speaking, swallowing, and maintaining neck stability. In this guide, we explore every aspect of this condition—from basic anatomy and types to causes, symptoms, diagnostic tests, treatment options, prevention methods, and when to see a doctor.
Anatomy of the Thyrohyoid Muscle
A thorough understanding of the thyrohyoid muscle’s anatomy is key to grasping what happens when it undergoes atrophy.
Structure and Location
-
Location:
-
Found in the front part of the neck, just above the thyroid cartilage and below the hyoid bone.
-
Part of a group of muscles called the infrahyoid muscles, often referred to as “strap muscles.”
-
Origin and Insertion
-
Origin:
-
Arises from the upper border of the thyroid cartilage.
-
-
Insertion:
-
Attaches to the lower border of the hyoid bone.
-
Blood Supply
-
Arterial Supply:
-
Typically receives blood from branches of the superior thyroid artery.
-
-
Venous Drainage:
-
Drains into nearby veins that connect to the jugular system.
-
Nerve Supply
-
Innervation:
-
The thyrohyoid muscle is mainly supplied by the hypoglossal nerve (cranial nerve XII) for motor control.
-
Some studies suggest that fibers from cervical nerves may also play a role.
-
Key Functions of the Thyrohyoid Muscle
-
Assisting in Swallowing:
-
Helps elevate the larynx during swallowing.
-
-
Stabilizing the Larynx:
-
Keeps the larynx steady during speech and swallowing.
-
-
Facilitating Voice Production:
-
Affects the tension on the vocal cords by influencing laryngeal position.
-
-

Types of Thyrohyoid Muscle Atrophy
While the condition may be categorized differently based on underlying mechanisms, the main types of thyrohyoid muscle atrophy include:
-
Disuse Atrophy:
-
Occurs when the muscle is not used regularly, often due to immobility or reduced physical activity.

Inflammatory Atrophy:
-
Associated with inflammatory conditions that may damage the muscle tissue.
