Tongue extrinsic muscle strain is an injury affecting the muscles that connect your tongue to surrounding structures in the mouth and throat. These muscles play a key role in moving your tongue for speech, eating, swallowing, and even breathing. When they are overstretched or torn, you may experience pain, stiffness, and difficulty speaking or swallowing.
A tongue extrinsic muscle strain occurs when one or more of the four main muscles that anchor the tongue (the genioglossus, hyoglossus, styloglossus, and palatoglossus) are overstretched or partially torn. This often happens due to sudden force (like accidentally biting your tongue), overuse (such as prolonged singing or loud talking), or improper tongue movements during medical procedures (for example, intubation). Strains are graded from mild (Grade I) with only a few muscle fibers affected, to severe (Grade III) with a complete tear of the muscle.
Anatomy of the Tongue Extrinsic Muscles
Structure & Location
-
Structure: These are skeletal (voluntary) muscles made of many fiber bundles.
-
Location: They lie partly outside the main body of the tongue, running between the tongue and bones or soft tissues at the back of the mouth and throat.
Origins & Insertions
-
Genioglossus
-
Origin: Mental spine on the inner surface of the lower jaw (mandible).
-
Insertion: Underside and midline of the tongue, and into the hyoid bone.
-
-
Hyoglossus
-
Origin: Body and greater horn of the hyoid bone.
-
Insertion: Side of the tongue.
-
-
Styloglossus
-
Origin: Styloid process of the temporal bone (behind the ear).
-
Insertion: Side and under-surface of the tongue.
-
-
Palatoglossus
-
Origin: Palatine aponeurosis (soft palate).
-
Insertion: Side of the tongue’s back part.
-
Blood Supply
-
Main Arteries: Lingual artery (branch of the external carotid artery) and its branches.
Nerve Supply
-
Hypoglossal nerve (Cranial Nerve XII): Supplies genioglossus, hyoglossus, and styloglossus.
-
Vagus nerve via pharyngeal plexus: Supplies palatoglossus.
Key Functions
-
Protrusion: Pushing the tongue out (mainly genioglossus).
-
Retraction: Pulling the tongue back in (styloglossus).
-
Elevation: Lifting parts of the tongue (palatoglossus raises the back).
-
Depression: Lowering parts of the tongue (hyoglossus).
-
Shaping: Forming the tongue’s surface for speech and swallowing.
-
Bolus Positioning: Moving food and liquid toward the throat during swallowing.
Types of Tongue Extrinsic Muscle Strain
-
Grade I (Mild): Few muscle fibers stretched, minor pain, little to no loss of function.
-
Grade II (Moderate): Partial muscle tear, moderate pain, some loss of strength and movement.
-
Grade III (Severe): Complete muscle tear, severe pain, major loss of tongue movement.
-
Acute Strain: Sudden onset after a specific injury or trauma.
-
Chronic Strain: Develops over time due to repetitive overuse (e.g., professional voice use).
-
Muscle-Specific Strain: Strain localized to one of the four muscles (e.g., isolated genioglossus strain).

Frequently Asked Questions
-
What exactly causes a tongue extrinsic muscle strain?
A strain happens when the tongue muscles are overstretched or partially torn, often from biting, overuse, or sudden force. -
How long does healing usually take?
Most mild strains improve in 1–2 weeks. Moderate strains can take 3–6 weeks. Severe tears may need months, especially if surgery is required. -
Can I still eat and speak with this injury?
Mild strains usually allow basic speech and soft foods. Moderate to severe strains can make both activities painful and difficult. -
Are imaging tests always required?
No. If your doctor can diagnose by exam alone and it’s a mild strain, they may skip imaging. Ultrasound or MRI is used for uncertain or severe cases. -
Will physical therapy help?
Yes. Speech or myofunctional therapy guides safe exercises to restore strength and flexibility without re‑injuring the muscle. -
Is surgery common?
No. Fewer than 5 percent of cases need surgery. It is reserved for complete tears or chronic, non‑healing injuries. -
What home remedies work best?
Rest, ice for the first 48 hours, then moist heat, gentle stretching, and pain relievers like acetaminophen or ibuprofen. -
Can I prevent this injury if I’m a singer or speaker?
Absolutely. Regular warm‑ups, proper vocal technique, and hydration reduce your risk significantly. -
Is tongue strain linked to tongue‑tie (ankyloglossia)?
Sometimes. A tight or short lingual frenulum can alter tongue mechanics and increase strain risk. -
Will it affect my taste?
Mild strains do not usually affect taste. Severe strains near nerve supply may temporarily change taste sensations. -
Can children get this injury?
Yes. Children who bite their tongues or have prolonged crying fits can experience tongue muscle strain. -
Should I use a night guard?
If you grind your teeth at night (bruxism), a custom mouthguard can protect your tongue from injury. -
Are muscle relaxants safe?
When prescribed and monitored by a doctor, short courses of muscle relaxants like cyclobenzaprine are generally safe. -
What if my tongue is still weak after recovery?
Ask your doctor about targeted therapy like neuromuscular electrical stimulation or extended myofunctional exercises. -
When is a strain actually a tear?
Severe pain, a palpable gap in the muscle, or loss of all normal tongue movement may indicate a complete tear (Grade III). Imaging and specialist referral are then needed.
