Styloglossus muscle strain is an injury to one of the key muscles that help move the tongue. When this thin, strap‑like muscle becomes overstretched or torn—often from sudden force, repetitive overuse, or direct trauma—it can cause pain, difficulty speaking, and swallowing problems.
A styloglossus muscle strain occurs when the styloglossus—a paired muscle originating on the temporal bone’s styloid process and inserting on the side and underside of the tongue—is overstretched or torn. This can range from mild microscopic tears (Grade I) to complete ruptures (Grade III). Common triggers include forceful tongue movements, sports injuries, dental procedures, or chronic overuse such as in professional singers or speakers. Strains often lead to pain in the floor of the mouth, speech changes, and difficulty swallowing.
Anatomy of the Styloglossus Muscle
-
Structure & Location
The styloglossus is a slender, fan‑shaped muscle located on the side of the tongue. It lies deep in the floor of the mouth, between the hyoglossus (below) and the palatoglossus (above), passing from the skull’s base down to the tongue’s lateral surface. -
Origin
This muscle starts at the styloid process of the temporal bone—a pointed projection just below the ear. -
Insertion
It attaches to the lateral aspect and inferior surface of the tongue, blending with fibers of the intrinsic tongue muscles. -
Blood Supply
The styloglossus receives oxygen‑rich blood from branches of the lingual artery, which itself stems from the external carotid artery. -
Nerve Supply
Motor control comes from the hypoglossal nerve (cranial nerve XII), which also innervates most other tongue muscles. -
Functions (Key Actions)
-
Tongue Retraction: Pulls the tongue backward into the mouth.
-
Tongue Elevation: Raises the sides and back of the tongue during swallowing.
-
Speech Articulation: Helps shape sounds by altering tongue position.
-
Swallowing Assistance: Elevates the tongue base, aiding in moving food back.
-
Oral Clearance: Works with other muscles to clear saliva or debris.
-
Coordination with Other Muscles: Balances the actions of stylohyoid and hyoglossus for smooth tongue motion.
-
Types of Styloglossus Muscle Strain
-
Grade I (Mild): Microscopic fiber tears, minimal loss of strength, mild discomfort.
-
Grade II (Moderate): Partial muscle fiber tear, noticeable pain, possible swelling, reduced tongue mobility.
-
Grade III (Severe): Complete muscle rupture, severe pain, major weakness, often requiring surgical repair.
-
Acute Strain: Sudden onset from a single event, like a sports collision or dental extraction.
-
Chronic Strain: Develops over time from repetitive overuse, as seen in singers, wind‑instrument musicians, or frequent public speakers.
Causes
-
Overextension during Yawning: Opening the mouth very wide can overstretch the styloglossus.
-
Forceful Tongue Thrusting: Habitual pushing of the tongue against teeth or lips strains muscle fibers.
-
Sports Trauma: Direct blows to the jaw or floor of the mouth in contact sports.
-
Dental Procedures: Prolonged mouth opening during surgery or heavy dental work.

When to See a Doctor

Early evaluation can prevent complications like chronic dysphagia or permanent muscle weakness.
Frequently Asked Questions
-
What exactly is the styloglossus muscle?
It’s a slender muscle that pulls your tongue backward and upward, helping you speak and swallow. -
How do I know if I’ve strained it?
You’ll feel tender pain under your jaw or on the tongue’s side, especially when moving or pressing the tongue. -
Is it serious if I can’t retract my tongue fully?
Limited retraction suggests moderate to severe strain—see a healthcare provider if it persists past two days. -
Can exercise make it worse?
Yes. Avoid tongue‑intensive activities like singing, playing wind instruments, or prolonged talking until pain subsides. -
Will a dentist catch this strain?
Dentists may notice stiffness or pain during mouth exams, but usually an ENT or oral surgeon diagnoses it. -
Do I need imaging tests?
Mild strains rely on clinical exam, but ultrasound or MRI is used when tears are suspected or recovery stalls. -
Are corticosteroid injections safe?
When guided properly, they can reduce inflammation without significant side effects; always done by specialists. -
How long does recovery take?
Grade I strains heal in 1–2 weeks; Grade II may take up to 4 weeks; Grade III may require months, including surgery and rehab. -
Can it recur?
Yes, without proper rehabilitation and prevention, the styloglossus strain can recur in active speakers or singers. -
Is physical therapy helpful?
Absolutely—speech therapists and myofascial specialists guide safe stretching and strengthening protocols. -
Can nerve damage occur?
Rarely, severe swelling can compress the hypoglossal nerve temporarily, causing numbness or weakness. -
What home remedies help?
Ice packs for the first 48 hours, then warm compresses, gentle tongue exercises, and a soft diet. -
Should I avoid certain foods?
Skip crunchy, hard, or very chewy foods during recovery to minimize tongue strain. -
Will Botox weaken my tongue permanently?
No—Botulinum toxin wears off in 3–4 months and is used only if conservative treatments fail. -
How can I prevent future strains?
Warm up, hydrate, practice good posture, take breaks during prolonged talking, and manage stress.
Conclusion
Styloglossus muscle strain, though uncommon, can significantly impact speaking, swallowing, and daily comfort. By understanding its anatomy, recognizing early symptoms, and following evidence‑based treatments—from rest and targeted exercises to medications and, in rare cases, surgery—you can speed recovery and prevent recurrence. Keep this guide handy whenever you experience tongue‑related pain, and don’t hesitate to consult a healthcare professional if symptoms persist beyond a couple of days.
