Suprahyoid Muscles Cancer

The suprahyoid muscles are a group of muscles located above the hyoid bone in your neck. They play a crucial role in swallowing, speaking, and other movements of the mouth and throat. Although cancers specifically starting in these muscles are uncommon, tumors in the head and neck region can invade or affect these muscles.

Anatomy of the Suprahyoid Muscles

Understanding the normal anatomy of the suprahyoid muscles helps in recognizing changes that may occur when cancer is present.

Structure and Location

• Location: The suprahyoid muscles are located in the upper neck, above the hyoid bone.

• Main Muscles Involved: They include the digastric (with anterior and posterior bellies), mylohyoid, geniohyoid, and stylohyoid muscles.

Origin and Insertion

• Digastric Muscle:

  • Anterior Belly: Originates from the lower jaw (mandible) near the chin.

  • Posterior Belly: Originates from the mastoid process behind the ear.

• Mylohyoid Muscle: Arises from the lower border of the mandible and inserts into the hyoid bone.

• Geniohyoid Muscle: Originates from the inner surface of the lower jaw (genial tubercles) and attaches to the hyoid bone.

• Stylohyoid Muscle: Begins at the temporal bone near the ear and extends down to the hyoid bone.

Blood Supply and Nerve Supply

• Blood Supply:

  • These muscles receive blood from branches of the facial artery, lingual artery, and other small vessels in the head and neck.

• Nerve Supply:

  • The muscles are controlled by cranial nerves and cervical nerves. For example, the mylohyoid and anterior belly of the digastric are innervated by the mylohyoid nerve (a branch of the mandibular nerve, CN V3).

Main Functions

1. Swallowing: Helps lift the hyoid bone and larynx during swallowing.

2. Mastication Support: Assists in the movement of the jaw during chewing.

3. Speech: Contributes to proper tongue and throat positioning, aiding speech.

4. Mouth Opening: Plays a role in depressing the mandible (opening the mouth).

5. Stabilization: Stabilizes the hyoid bone for other neck functions.

6. Facial Expression Support: Assists in movements that affect facial expressions, particularly near the jawline.

Types of Cancers Involving the Suprahyoid Region

While a “suprahyoid muscles cancer” is rare, cancers in this area generally fall into broader categories, such as:

• Head and Neck Squamous Cell Carcinoma (HNSCC):
  Cancers arising from the mucosal surfaces that can extend into adjacent muscles.

• Soft Tissue Sarcomas:
  Rare cancers that develop in soft tissues, including muscle, fat, or connective tissue, sometimes affecting the suprahyoid region.

• Rhabdomyosarcoma:
  A type of sarcoma that originates from muscle cells, more common in children.

• Metastatic Cancers:
  Cancers from other parts of the body that spread to the neck region.

Each type may require different treatment approaches, and the exact classification depends on the origin and spread of the tumor.
