Sternohyoid Muscle Fibrosis

Anatomy of the Sternohyoid Muscle

Understanding the anatomy of the sternohyoid muscle is key to knowing how fibrosis affects it.

Structure and Location

• Location: The sternohyoid is one of the infrahyoid muscles, found on the front of the neck. It lies between the sternum? (breastbone?) and the hyoid bone (a small U-shaped bone at the base of the tongue).

• Appearance: It is a thin, flat, and strap-like muscle that runs vertically along the neck.

Origin and Insertion

• Origin: The muscle originates from the manubrium of the sternum (upper part of the sternum) and sometimes from the adjacent clavicle?.

• Insertion: It attaches to the lower part of the hyoid bone, helping to pull it downward.

Blood Supply and Nerve Supply

• Blood Supply: The sternohyoid receives blood from small branches of the inferior thyroid? artery? and other nearby vessels.

• Nerve Supply: It is innervated by branches of the ansa cervicalis (a loop of nerves in the neck), which controls the function of several infrahyoid muscles.

Main Functions

1. Depressing the Hyoid Bone: Helps lower the hyoid during swallowing and speaking.

2. Stabilizing the Hyoid: Provides support to the hyoid bone for proper tongue movement.

3. Aiding in Swallowing: Plays a role in the mechanics of swallowing.

4. Assisting in Speech: Contributes to the positioning of the hyoid bone during voice production.

5. Maintaining Neck Posture: Helps in stabilizing the neck’s soft tissues.

6. Facilitating Breathing: Works in coordination with other muscles during breathing.

Types of Sternohyoid Muscle Fibrosis

Sternohyoid muscle fibrosis can be categorized based on its cause or the pattern of tissue change:

• Idiopathic? Fibrosis: Develops without a known cause.

• Post-Traumatic Fibrosis: Results from an injury or neck trauma?.

• Inflammatory Fibrosis: Associated with chronic? inflammation? from autoimmune? or infectious conditions.

• Post-Surgical Fibrosis: Occurs after neck or throat? surgery.

• Radiation-Induced Fibrosis: Develops as a side effect? of radiation therapy? in the neck region.

• Overuse-Related Fibrosis: Due to repetitive strain? or chronic overuse of the neck muscles.

Causes of Sternohyoid Muscle Fibrosis

Below are 20 potential causes that can lead to fibrosis in the sternohyoid muscle:

1. Neck Trauma or Injury: Blunt force or whiplash injuries can damage muscle fibers.

2. Surgical Trauma: Neck or thyroid surgeries may inadvertently cause scarring.

3. Radiation Therapy: Treatment for head and neck cancers may lead to tissue damage.

4. Chronic Inflammation: Persistent inflammatory conditions can cause fibrosis.

5. Autoimmune Disorders: Conditions like rheumatoid arthritis? may lead to muscle scarring.

6. Viral? Infections: Some viral illnesses can trigger inflammation in the muscle.

7. Bacterial? Infections: Infections such as abscesses in the neck region.
