Sternohyoid Muscle Injuries

The sternohyoid muscle is a small but important muscle located in the front of the neck. It plays a key role in the movement of the hyoid bone and in swallowing. When this muscle is injured, it can lead to pain, difficulty swallowing, and other complications. In this guide, we explain the anatomy, types of injuries, causes, symptoms, diagnostic tests, treatments (both non-pharmacological and pharmacological), surgical options, prevention tips, and when to see a doctor.

Anatomy of the Sternohyoid Muscle

Understanding the basic anatomy of the sternohyoid muscle is crucial for recognizing how injuries can occur and how they may affect you.

Structure and Location

• Location: The sternohyoid muscle is found on the front (anterior) aspect of the neck.

• Appearance: It is a thin, flat muscle that runs vertically from the upper chest to the hyoid bone.

Origin

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

• Plain English: In simpler terms, the muscle starts at the upper part of your breastbone, close to where your collarbones meet.

Insertion

• Insertion Point: It inserts into the inferior (lower) border of the hyoid bone.

• Plain English: The muscle attaches to a small bone in your neck that is essential for swallowing and speaking.

Blood Supply

• Key Artery: The sternohyoid muscle receives blood mainly from branches of the inferior thyroid artery.

• Plain English: A branch of an artery near your thyroid gland supplies blood to this muscle, keeping it healthy and functioning.

Nerve Supply

• Innervation: The nerve supply comes primarily from the ansa cervicalis, a loop of nerves in the neck.

• Plain English: A small network of nerves in your neck sends signals to the sternohyoid muscle, telling it when to contract or relax.

Main Functions

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

2. Assisting in Speech: Supports movements required for clear speech.

3. Facilitating Swallowing: Aids in the complex process of swallowing by stabilizing the hyoid bone.

4. Neck Stabilization: Contributes to the overall stability of the front neck region.

5. Coordination with Other Muscles: Works alongside other neck muscles to perform smooth and coordinated movements.

6. Postural Support: Helps maintain proper posture of the neck during daily activities.

Types of Sternohyoid Muscle Injuries

Sternohyoid muscle injuries can vary in severity and type. Here are some common categories:

1. Strain: Overstretching or tearing of muscle fibers.

2. Partial Tear: Some fibers are damaged but the muscle is not completely torn.

3. Complete Tear: The muscle is fully torn, often requiring surgical repair.

4. Contusion: A bruise caused by a direct blow or trauma.

5. Overuse Injury: Repetitive motions can lead to inflammation and strain.

6. Traumatic Injury: Direct impact from accidents or sports-related injuries.

7. Iatrogenic Injury: Damage that occurs during medical procedures, such as neck surgery.

8. Repetitive Stress Injury: Long-term repetitive activities leading to chronic inflammation.

9. Inflammatory Injury: Conditions like myositis (muscle inflammation) affecting the muscle.

10. Degenerative Injury: Age-related wear and tear on the muscle.
