Suprahyoid muscle spasm is a condition involving involuntary contractions of the muscles located above the hyoid bone (a small, U-shaped bone in the front of your neck). These muscles play important roles in swallowing, speech, and jaw movement. When they spasm, it can lead to pain, discomfort, and difficulties with everyday functions. This guide provides clear, evidence-based information on the anatomy, causes, symptoms, diagnostic tests, treatment options, and more.
Anatomy of the Suprahyoid Muscles
Structure and Location
The suprahyoid muscles are a group of small muscles situated in the upper neck, just above the hyoid bone. They lie beneath the chin and are involved in many essential functions such as swallowing and speaking. Key muscles in this group include:
Digastric Muscle: Has two bellies (anterior and posterior) that help depress the jaw.
Mylohyoid Muscle: Forms the floor of the mouth and supports the tongue.
Geniohyoid Muscle: Runs from the chin (genial tubercles) to the hyoid bone, helping to pull the hyoid upward.
Stylohyoid Muscle: Stretches from the styloid process of the temporal bone to the hyoid bone.
Origin and Insertion
Each suprahyoid muscle has a unique origin and insertion point:
Digastric Muscle:
Origin: Anterior belly originates from the digastric fossa of the mandible; posterior belly originates from the mastoid notch of the temporal bone.
Insertion: Both bellies converge on an intermediate tendon that attaches to the hyoid bone.
Mylohyoid Muscle:
Origin: Mylohyoid line of the mandible.
Insertion: Forms a muscular sheet that attaches to the hyoid bone.
Geniohyoid Muscle:
Origin: Inner surface of the mandible at the chin.
Insertion: Body of the hyoid bone.
Stylohyoid Muscle:
Origin: Base of the skull from the styloid process.
Insertion: Hyoid bone.
Blood Supply and Nerve Supply
Blood Supply:
The suprahyoid muscles receive blood from several arteries, including branches of the facial, lingual, and sometimes the occipital arteries. This rich blood supply ensures that the muscles get the oxygen and nutrients they need to function.Nerve Supply:
These muscles are mainly controlled by cranial nerves:The mylohyoid nerve (a branch of the inferior alveolar nerve from the mandibular division of the trigeminal nerve) supplies the mylohyoid and anterior belly of the digastric.
Other cranial nerves, such as branches from the facial nerve, assist in controlling muscle function.
Key Functions of the Suprahyoid Muscles
Swallowing: Elevate the hyoid bone during swallowing to help open the upper esophageal sphincter.
Speech: Contribute to the movement of the tongue and floor of the mouth, aiding in articulation.
Jaw Movement: Assist in depressing and stabilizing the jaw during speaking and chewing.
Breathing: Help maintain airway patency during swallowing.
Postural Support: Stabilize the hyoid bone, which supports the tongue and throat.
Mastication (Chewing): Work in coordination with other muscles to support chewing motions.
A suprahyoid muscle spasm occurs when one or more of these muscles involuntarily contract or tighten. This can lead to pain and may affect functions such as swallowing, speech, and even breathing. While muscle spasms are common in many parts of the body, when they occur in the suprahyoid region, they can cause discomfort in the neck, chin, and lower jaw.
Types of Suprahyoid Muscle Spasm
There isn’t a single, universally agreed-upon classification for suprahyoid muscle spasms, but they can generally be grouped into:
Acute Spasm: Sudden onset, often due to overuse or a minor injury.
Chronic Spasm: Ongoing or recurrent spasms that may be related to stress, nerve irritation, or underlying conditions.
Referred Spasm: Spasms that occur as a secondary response to problems in nearby structures (such as temporomandibular joint disorders or dental issues).
Each type can vary in severity and may require different treatment approaches.
Causes of Suprahyoid Muscle Spasm
Understanding the potential causes can help in both treatment and prevention. Here are 20 possible causes:
Muscle Overuse: Prolonged or excessive use of the muscles (e.g., extended talking or chewing gum).
Poor Posture: Incorrect head or neck alignment that strains the muscles.
Stress: Emotional stress can lead to muscle tension.
Anxiety: Similar to stress, anxiety may cause muscle tightness and spasms.
Temporomandibular Joint (TMJ) Disorders: Problems with the jaw joint can cause muscle tension in the surrounding areas.
Bruxism (Teeth Grinding): Habitual grinding or clenching of the teeth can strain the muscles.
Dysphagia: Difficulty in swallowing that forces the muscles to work harder.
Neck Injury: Trauma to the neck may trigger spasm in the nearby muscles.
Chin Injury: Direct injury to the chin area can lead to reflexive muscle spasm.
Nerve Irritation: Compression or irritation of nerves supplying the muscles.
Inflammation: Localized inflammation from infection or injury.
Vitamin Deficiencies: Low levels of magnesium, calcium, or other minerals can trigger spasms.
Dental Problems: Issues with teeth alignment or dental procedures may affect muscle balance.
Sleep Disorders: Poor sleep can increase muscle tension.
Gastroesophageal Reflux Disease (GERD): Acid reflux can lead to throat and muscle irritation.
Voice Overuse: Excessive talking or singing can tire and spasm the muscles.
Post-Surgical Complications: Surgery in the neck or jaw region may lead to temporary muscle spasms.
Congenital Abnormalities: Birth defects that affect muscle structure or nerve supply.
Autoimmune Conditions: Diseases like myositis may cause muscle inflammation and spasm.
Neurological Disorders: Conditions such as dystonia can involve involuntary muscle contractions.

Partial Resection of the Muscle: Removing a small portion of the muscle to reduce its spasm.
Debridement of Scar Tissue: If prior injury has led to scar formation, surgical removal can improve function.
Open Surgical Release: Directly exposing and releasing the tight muscle.
Nerve Decompression Surgery: Relieving pressure on nerves that may be triggering spasms.
Minimally Invasive Muscle Release Procedure: Using small incisions and specialized instruments to release the spastic muscle.
Note: Surgery is generally reserved for cases that do not respond to conservative treatments.
Preventive Measures
Preventing suprahyoid muscle spasms is often possible with lifestyle modifications and proper self-care. Consider these tips:
Maintain Good Posture: Keep your head and neck aligned to reduce muscle strain.
Regular Stretching: Perform daily neck and jaw stretches to keep muscles flexible.

Balanced Diet: Ensure you’re getting enough vitamins and minerals (like magnesium and calcium) to support muscle health.
Avoid Excessive Jaw Clenching: Be conscious of habits such as teeth grinding or clenching.
Voice Rest: Give your vocal cords and associated muscles a break if you use your voice extensively.
Regular Dental Check-ups: Maintain good oral health to prevent issues that may affect the jaw and neck muscles.
When to See a Doctor
It’s important to consult a healthcare provider if you experience any of the following:
Persistent or Severe Pain: If the discomfort does not improve with self-care.
Difficulty Swallowing: Problems with swallowing that may lead to nutritional issues.
Trouble Speaking or Breathing: Any interference with these vital functions should be evaluated.
