The suprahyoid muscles are a group of small muscles located above the hyoid bone in your neck. These muscles play a key role in everyday activities such as swallowing, speaking, chewing, and even maintaining the position of your jaw. When these muscles are injured, overused, or affected by various health conditions, you may experience pain, difficulty swallowing, or other problems that interfere with daily life.
Anatomy of the Suprahyoid Muscles
Understanding the anatomy of the suprahyoid muscles is essential for grasping how their disorders affect you. These muscles are located in the upper neck region and serve several important functions.
Structure & Location
-
Location: The suprahyoid muscles are found above the hyoid bone (a small, U-shaped bone in the neck) and beneath the jaw (mandible).
-
Key Muscles: This group typically includes:
-
Digastric muscle: Has two bellies (anterior and posterior) and helps in opening the mouth.
-
Mylohyoid muscle: Forms the floor of the mouth and assists with swallowing.
-
Geniohyoid muscle: Runs from the chin (genial tubercles) to the hyoid bone.
-
Stylohyoid muscle: Extends from the styloid process of the skull to the hyoid bone.
-
Origin & Insertion
-
Origin: Each muscle begins (originates) from a different part of the skull or jaw. For example, the anterior belly of the digastric originates near the lower border of the mandible.
-
Insertion: The muscles attach (insert) onto the hyoid bone or nearby structures. For instance, the mylohyoid inserts along the midline of the hyoid bone, forming a muscular floor for the mouth.
Blood Supply
-
Arterial Supply: Blood is delivered to these muscles by branches of the facial and lingual arteries. One key branch is the submental artery, which supplies parts of the digastric and mylohyoid muscles.
-
Venous Drainage: The veins in this region drain into the external jugular system.
Nerve Supply
-
Motor Innervation:
-
The digastric muscle is partially innervated by the trigeminal nerve (cranial nerve V) for its anterior belly and by the facial nerve (cranial nerve VII) for its posterior belly.
-
The geniohyoid and mylohyoid muscles are mainly innervated by the mylohyoid nerve, a branch of the mandibular division of the trigeminal nerve.
-
The stylohyoid muscle is also supplied by a branch of the facial nerve.
-
-
Sensory Innervation: While these muscles themselves do not carry significant sensory fibers, surrounding structures may have their own nerve supplies that contribute to pain perception.
Key Functions
-
Elevation of the Hyoid Bone: During swallowing and speaking, these muscles help lift the hyoid bone.
-
Depression of the Mandible: They assist in opening the mouth by lowering the jaw.
-
Stabilization: They help stabilize the hyoid bone, which is crucial for proper tongue and neck function.
-
Swallowing: By coordinating with other muscles, they play a role in the safe passage of food and liquid.
-
Speech Articulation: They contribute to clear speech by supporting movements of the tongue and jaw.
-
Assistance in Breathing: In some cases, by maintaining the structure of the upper airway, they indirectly support breathing.
Types of Suprahyoid Muscle Disorders
Disorders of the suprahyoid muscles can vary widely. They might result from injury, overuse, or underlying health conditions. Some of the common types include:
-
Myofascial Pain Syndrome: Chronic muscle pain and tenderness due to the formation of trigger points.
-
Muscle Strain/Injury: Overuse or sudden trauma can strain the muscles.
-
Inflammatory Conditions: Inflammation (myositis) can occur due to infection or autoimmune reactions.
-
Neuromuscular Disorders: Problems in nerve-to-muscle communication (e.g., due to nerve injury or neurological conditions) can impair muscle function.
-
Temporomandibular Joint (TMJ) Dysfunction: Often involves the suprahyoid muscles, contributing to jaw pain and difficulty chewing.
-
Post-Surgical Complications: Surgery in the head and neck area may inadvertently affect these muscles.
-
Congenital Abnormalities: Some people are born with structural anomalies that affect muscle function.
-
Oropharyngeal Dysphagia: Difficulty swallowing due to poor muscle coordination.
-
Tension-Type Disorders: Stress-related tension can cause the muscles to tighten excessively.
-
Fibrotic Changes: Scar tissue formation following injury can restrict muscle movement.
Causes of Suprahyoid Muscle Disorders
A variety of factors may contribute to suprahyoid muscle disorders. Below are 20 potential causes explained in plain language:
-
Muscle Overuse: Repeated or intense activity such as chewing gum or speaking for long periods can lead to muscle fatigue and strain.

Trauma: A direct blow or accident that injures the neck can damage the muscles.
-
Infections: Bacterial or viral infections can cause inflammation in the muscle tissues.
-
Poor Posture: Slouching or improper head positioning may put extra stress on these muscles.
-
