Infrahyoid muscles cancer is a rare and unusual type of cancer that originates in the muscles located in the lower part of your neck. These muscles—located below the hyoid bone—play a role in swallowing, speaking, and stabilizing the larynx (voice box).
Infrahyoid muscles cancer is a malignant growth that develops in one or more of the muscles situated below the hyoid bone in the neck. It is extremely rare and may sometimes be classified as a type of soft tissue sarcoma—a cancer arising from the tissues that support the body.
Key Points:
Rare Occurrence: Because the infrahyoid muscles are not common sites for cancer, cases are unusual.
Origin of the Cancer: It can develop from the muscle tissue itself or, in some cases, may represent a metastasis (spread) from a primary cancer located elsewhere.
Impact on Function: Since these muscles help with swallowing, speaking, and supporting the throat, any tumor in this area might affect these functions.
Anatomy of the Infrahyoid Muscles
Understanding the anatomy of the infrahyoid muscles is key to knowing how cancer in this area might affect your body. Below are the details about their structure, location, origin, insertion, blood supply, nerve supply, and functions.
A. Structure and Location
The infrahyoid muscles are a group of four pairs of muscles located in the front of your neck, beneath the hyoid bone. They include:
Sternohyoid: Runs from the sternum (breastbone) upward to the hyoid bone.
Sternothyroid: Extends from the sternum to the thyroid cartilage.
Omohyoid: Has two bellies (upper and lower) that connect from the shoulder area to the hyoid bone.
Thyrohyoid: Stretches between the thyroid cartilage and the hyoid bone.
B. Origin and Insertion
Origin:
Sternohyoid: Originates at the manubrium (upper part of the sternum).
Sternothyroid: Begins at the posterior surface of the manubrium.
Omohyoid: The inferior belly starts at the scapula (shoulder blade) area.
Thyrohyoid: Originates on the thyroid cartilage.
Insertion:
Sternohyoid: Inserts on the lower border of the hyoid bone.
Sternothyroid: Inserts on the thyroid cartilage.
Omohyoid: The superior belly inserts on the hyoid bone.
Thyrohyoid: Inserts on the hyoid bone near its superior border.
C. Blood Supply
Each muscle receives blood from small arteries that branch off from the major vessels in the neck:
Branches from the superior thyroid artery.
Contributions from the inferior thyroid artery.
Smaller perforating branches may also supply these muscles.
D. Nerve Supply
The nerves that control the infrahyoid muscles are mainly branches of the:
Ansa Cervicalis: A loop of nerves in the cervical (neck) region that provides motor innervation to these muscles.
Cervical Spinal Nerves: Some accessory innervation may come from these nerves.
E. Six Key Functions of the Infrahyoid Muscles
Swallowing:
They help move the hyoid bone and larynx during swallowing.Speech Production:
By stabilizing the larynx, they support clear speech.Neck Movement:
Assist in subtle movements and stabilization of the neck.Assisting Breathing:
Indirectly support the airway by maintaining laryngeal position.Facilitating Head Positioning:
Help control the position of the head relative to the neck.Supporting the Throat:
Provide structural support for the throat during various activities like coughing or laughing.
Types of Infrahyoid Muscles Cancer
Although cancer originating in the infrahyoid muscles is rare, there are a few types or classifications that can be considered:
Soft Tissue Sarcoma:
A group of cancers that arise from connective tissues, including muscle.Leiomyosarcoma:
A cancer that arises from smooth muscle cells and can sometimes affect the neck.Rhabdomyosarcoma:
A type of cancer more commonly seen in children that originates from skeletal muscle cells.Undifferentiated Pleomorphic Sarcoma:
A category of cancer that may include cells that do not resemble normal cells.Metastatic Lesions:
Tumors that have spread to the infrahyoid muscles from a primary cancer located elsewhere in the body.Other Rare Subtypes:
There may be other less common forms that affect the muscle tissue in this region.
Note:
Classification is largely based on the cell type, how the cells look under a microscope, and the tumor’s behavior.
