Thyrohyoid muscle cancer is a very uncommon condition that affects a small muscle located in the neck between the thyroid cartilage and the hyoid bone. Because cancers in this location are rare, many of the treatment principles and diagnostic approaches are similar to those used for head and neck cancers in general. In this guide, we explain in plain language the anatomy, potential causes, symptoms, diagnostic tests, treatment options, and preventive strategies associated with this type of cancer.
Anatomy of the Thyrohyoid Muscle
Understanding the anatomy of the thyrohyoid muscle is key to comprehending how cancer in this region might affect function and spread.
Structure and Location
-
Location:
The thyrohyoid muscle is located in the upper neck. It lies between the thyroid cartilage (part of the voice box) and the hyoid bone (a small, U-shaped bone in the neck that supports the tongue). -
Surrounding Structures:
It is close to important structures such as the larynx (voice box), pharynx (throat), and various nerves and blood vessels that serve the head and neck.
Origin and Insertion
-
Origin:
The muscle originates from the upper border of the thyroid cartilage. In simple terms, this means it starts from the cartilage that helps form your voice box. -
Insertion:
It attaches to the hyoid bone, which is the small, movable bone in your neck. This connection helps support the movement of the larynx during speech and swallowing.
Blood Supply and Nerve Supply
-
Blood Supply:
The blood vessels that supply the thyrohyoid muscle come from branches of nearby arteries. These small vessels provide the oxygen and nutrients needed for the muscle’s health and function. -
Nerve Supply:
The muscle is controlled by nerves from the cervical plexus—a network of nerves in the neck. These nerves help coordinate the muscle’s movement, especially during actions such as swallowing and speaking.
Key Functions of the Thyrohyoid Muscle
-
Support of the Larynx:
Helps hold the larynx in the correct position for effective voice production. -
Facilitating Swallowing:
Assists in the complex movement required for safe swallowing by adjusting the position of the larynx. -
Speech Production:
Plays a role in modifying the tension and position of the vocal cords, which influences voice quality. -
Stabilizing the Neck:
Contributes to the overall support structure of the neck, working with other muscles to maintain stability. -
Assisting in Breathing:
Although indirectly, the muscle’s role in maintaining the structure of the throat aids in smooth breathing. -
Coordination with Other Neck Muscles:
Works with other muscles to ensure that movements such as head turning and posture maintenance are performed smoothly.
Because primary cancer of the thyrohyoid muscle is rare, it is usually discussed within the broader context of head and neck cancers. The area may be affected by cancers that originate in nearby tissues and then involve the thyrohyoid muscle.
Thyrohyoid muscle cancer refers to the development of malignant (cancerous) cells within or invading the thyrohyoid muscle. In many cases, the cancer may start in nearby structures (such as the larynx or thyroid) and spread to the muscle.
Types of Thyrohyoid Muscle Cancer
While there is no single classification solely for thyrohyoid muscle cancer, the following types of malignancies might involve the thyrohyoid area:
-
Squamous Cell Carcinoma:
Often found in head and neck cancers, these cells can invade adjacent muscles, including the thyrohyoid. -
Sarcomas:
These are cancers that begin in the soft tissues (muscle, fat, or connective tissues) and may rarely develop in the muscles of the neck. -
Metastatic Cancers:
Sometimes, cancers from other parts of the body spread to the neck muscles. -
Anaplastic Carcinoma:
A rare and aggressive type that can affect various tissues in the neck.
Note: The type and behavior of the cancer influence the treatment options and prognosis.
Causes of Thyrohyoid Muscle Cancer
There are many factors that can contribute to the development of cancers in the head and neck region, including the thyrohyoid muscle area. Below are 20 potential causes or risk factors:
-

Previous History of Head and Neck Cancer:
Recurrence or second primary cancers. -
Viral Infections Other Than HPV:
Certain other viruses may also be linked to cancer. -
Chronic Laryngitis:
Persistent inflammation of the voice box can lead to cell changes. -
Genetic Mutations:
