Infrahyoid Muscles Neuralgia

Infrahyoid muscles neuralgia refers to nerve pain that originates in or affects the group of muscles located beneath the hyoid bone in the neck. These muscles help control important functions like swallowing, speaking, and stabilizing the larynx. When the nerves supplying these muscles become irritated or injured, it can result in pain, stiffness, and other symptoms that interfere with daily activities.

Anatomy of the Infrahyoid Muscles

Understanding the anatomy is key to grasping why neuralgia in these muscles occurs.

Structure & Location

The infrahyoid muscles are a group of muscles situated in the anterior (front) part of the neck, below the hyoid bone. They are often referred to as the “strap muscles” due to their long, flat shape.

Main Muscles, Origin, and Insertion

There are four primary infrahyoid muscles:

1. Sternohyoid Muscle

   • Origin: Manubrium of the sternum and the medial end of the clavicle

   • Insertion: Inferior border of the hyoid bone

   • Function: Depresses the hyoid bone during swallowing

2. Omohyoid Muscle

   • Origin: Superior border of the scapula

   • Insertion: Inferior border of the hyoid bone via an intermediate tendon

   • Function: Depresses and retracts the hyoid bone, aiding in swallowing

3. Sternothyroid Muscle

   • Origin: Posterior surface of the manubrium and adjacent part of the sternum

   • Insertion: Thyroid cartilage of the larynx

   • Function: Lowers the larynx during speech and swallowing

4. Thyrohyoid Muscle

   • Origin: Upper border of the thyroid cartilage

   • Insertion: Inferior border of the hyoid bone

   • Function: Elevates the larynx or depresses the hyoid bone depending on which structure is fixed

Other muscles sometimes included are the platysma and additional neck muscles, but the four listed above are the core infrahyoid muscles.

Blood Supply

• Arterial Supply: Mainly through branches of the superior thyroid artery and inferior thyroid artery.

• Venous Drainage: Corresponding veins that drain into the jugular venous system.

Nerve Supply

• The nerves that supply these muscles mostly come from the ansa cervicalis, a loop of nerves formed by branches from the cervical spinal nerves (typically C1–C3).

• Additional nerve contributions may come from direct branches of the cervical plexus.

Main Functions of the Infrahyoid Muscles

1. Depression of the Hyoid Bone: Critical during swallowing to move the hyoid bone downward.

2. Depression of the Larynx: Helps in voice modulation and swallowing.

3. Stabilization: Provides support and stability to the neck and laryngeal structures.

4. Facilitation of Swallowing: Coordinates with other muscles to allow smooth passage of food.

5. Speech Modulation: Assists in controlling the tension of the larynx during speech.

6. Neck Movement: Contributes to the subtle movements and positioning of the neck.

Types of Infrahyoid Muscles Neuralgia

Although infrahyoid neuralgia is not as commonly discussed as other types of nerve pain, it can be categorized based on its cause or the pattern of nerve involvement. Types may include:

• Idiopathic Neuralgia: Nerve pain with no identifiable cause.

• Post-Traumatic Neuralgia: Occurring after injury or trauma to the neck.

• Post-Surgical Neuralgia: Following surgery in the neck region, such as thyroid or neck dissections.

• Referred Neuralgia: Pain originating in other structures (e.g., cervical spine) but felt in the infrahyoid region.

• Inflammatory Neuralgia: Related to conditions that cause inflammation (e.g., infections or autoimmune disorders).
