Sternohyoid muscle infection is a rare but important condition that affects one of the strap muscles in the neck. Infections in this muscle can cause pain, swelling, and other symptoms that may affect your ability to swallow, speak, or move your neck comfortably.
Anatomy of the Sternohyoid Muscle
Understanding the structure and function of the sternohyoid muscle is key to grasping what happens when it becomes infected.
Structure & Location
-
Location: The sternohyoid is one of the strap muscles located in the front of the neck. It lies close to the skin, making it part of the superficial muscular layer.
-
Origin: It originates from the upper part of the sternum (manubrium) and the medial end of the clavicle.
-
Insertion: The muscle extends upward to insert on the lower border of the hyoid bone, which is a U-shaped bone in the neck that supports the tongue.
Blood Supply and Nerve Supply
-
Blood Supply: The muscle 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 network of nerves that supply several infrahyoid muscles.
Key Functions
-
Depressing the Hyoid Bone: It helps pull the hyoid bone downward during swallowing.
-
Stabilizing the Hyoid: Works together with other strap muscles to keep the hyoid bone in place.
-
Facilitating Swallowing: Plays a role in the coordinated movement needed to swallow.
-
Assisting in Speech: Helps stabilize structures that affect voice and speech.
-
Supporting Neck Movements: Contributes to the overall function and movement of the neck.
-
Postural Support: Supports the cervical region by providing tension and structure.
A sternohyoid muscle infection occurs when bacteria, viruses, or other pathogens invade the tissue of this muscle, causing inflammation and sometimes abscess formation. Though infections in this muscle are uncommon, they can result from trauma, spread from nearby structures, or post-surgical complications.
Key Points:
-
Inflammatory Response: The body reacts to the invading organism by sending immune cells to the area, leading to redness, swelling, and pain.
-
Abscess Formation: In some cases, the infection may lead to a collection of pus (an abscess), which may require drainage.
-
Impact on Function: Inflammation may interfere with swallowing and neck movement.
Types of Sternohyoid Muscle Infections
While the sternohyoid muscle infection is not as widely categorized as infections in larger muscle groups, it can be classified based on several criteria:
-
Based on the Pathogen Involved:
-
Bacterial Infections: The most common type, often caused by common bacteria.
-
Viral Infections: Less common, may occur alongside systemic viral illnesses.
-
Fungal Infections: Rare but possible, particularly in immunocompromised individuals.
-
-
Based on the Infection’s Depth:
-
Superficial Infections: Affecting the outer layers of the muscle.
-
Deep-Seated Infections: Involving deeper muscle fibers and sometimes spreading to adjacent tissues.
-
-
Based on Complications:
-
Abscess Formation: Localized collections of pus within the muscle.
-
Necrotizing Infections: A severe form that leads to tissue death, though this is very rare.
-
Causes of Sternohyoid Muscle Infection
The following is a list of potential causes. These factors may contribute directly or indirectly to the development of an infection in the sternohyoid muscle:
-
Bacterial Invasion from Skin Injuries: Cuts or abrasions on the neck can introduce bacteria.
-
Post-Surgical Infection: Infection after neck or thyroid surgeries.
-
Contiguous Spread from Dental Infections: Infections from dental abscesses may spread.

Common symptoms include neck pain, swelling, redness, fever, and difficulty swallowing.
FAQ 4: Is this type of infection common?
No, infections of the sternohyoid muscle are relatively rare compared to other soft tissue infections.
FAQ 5: Which bacteria are most often involved?
Common bacteria include those found on the skin and in the throat, such as Staphylococcus aureus.
FAQ 6: What tests are used to diagnose it?
Doctors may use blood tests, imaging studies (ultrasound, CT, MRI), and sometimes needle aspiration to diagnose the infection.
FAQ 7: Can this infection cause an abscess?
Yes, if the infection worsens, it can lead to abscess formation, which may need drainage.
