Infrahyoid Muscle Tears

Infrahyoid muscles are a group of muscles located in the front of your neck. They play an essential role in swallowing and speaking. When these muscles are injured or torn, it can lead to discomfort and difficulties with daily activities. This article explains, in simple language, what infrahyoid muscle tears are, how they happen, and what you can do about them.

Anatomy of the Infrahyoid Muscles

Infrahyoid muscles are found beneath the hyoid bone (a U-shaped bone in the neck). There are typically four main muscles in this group:

1. Sternohyoid

2. Omohyoid

3. Sternothyroid

4. Thyrohyoid

Structure & Location

• Structure: These muscles are long, thin, and strap-like. They run vertically in the neck.

• Location: They are found in the anterior (front) region of the neck, extending from the sternum and shoulder area up to the hyoid bone and thyroid cartilage.

Origin and Insertion

• Sternohyoid:

  • Origin: Manubrium of the sternum.

  • Insertion: Inferior border of the hyoid bone.

• Omohyoid:

  • Origin: Superior border of the scapula (shoulder blade).

  • Insertion: Inferior border of the hyoid bone.

• Sternothyroid:

  • Origin: Manubrium of the sternum and the first costal cartilage.

  • Insertion: Thyroid cartilage of the larynx.

• Thyrohyoid:

  • Origin: Upper border of the thyroid cartilage.

  • Insertion: Inferior border of the hyoid bone.

Blood Supply

• Sternohyoid and Sternothyroid: Mainly receive blood from branches of the superior thyroid artery.

• Omohyoid and Thyrohyoid: Receive blood from small branches that also come off the superior thyroid artery and nearby vessels.

Nerve Supply

• All Infrahyoid Muscles: Are primarily innervated by the ansa cervicalis, a loop of nerves from the cervical plexus.

Key Functions

1. Depressing the Hyoid Bone: They pull the hyoid bone downward during swallowing.

2. Depressing the Larynx: Helping to lower the larynx (voice box) during swallowing.

3. Stabilizing the Hyoid Bone: Keeping the hyoid bone steady during speech and eating.

4. Assisting in Swallowing: Working with other muscles to ensure food passes safely from the mouth to the stomach.

5. Voice Modulation: Contributing to the movement and tension of the larynx which affects voice tone.

6. Facilitating Breathing: Although not a primary breathing muscle, their positioning helps maintain proper airway structure.

An infrahyoid muscle tear is an injury where one or more of these muscles suffer a partial or complete tear. This injury can occur due to sudden trauma or repetitive strain, leading to pain and impaired function.

Types of Infrahyoid Muscle Tears

Infrahyoid muscle tears can vary in severity and presentation. Common classifications include:

1. Partial Tear: Only some of the muscle fibers are torn.

2. Complete Tear: The muscle is completely torn into two pieces.

3. Acute Tear: Occurs suddenly, typically from a single injury or trauma.

4. Chronic Tear: Develops over time from repetitive strain or overuse.

5. Isolated Tear: Involves one specific muscle.

6. Combined Tear: More than one of the infrahyoid muscles is affected.
