A tongue extrinsic muscle sprain happens when one or more of the muscles that move the tongue get overstretched or torn. Unlike small tears inside the mouth, this sprain affects muscles attaching the tongue to bones, making tongue movement painful and weak. Evidence shows timely rest and proper care speed recovery and prevent lasting problems.
Anatomy of Tongue Extrinsic Muscles
The tongue’s extrinsic muscles originate outside the tongue and attach to it, controlling its position. There are four: genioglossus, hyoglossus, styloglossus, and palatoglossus. Below is their detailed anatomy:
Structure & Location
The genioglossus sits at the front floor of the mouth, fan‑shaped. Hyoglossus lies below, spanning from the hyoid bone upward. Styloglossus runs from the skull’s styloid process down to the tongue’s side. Palatoglossus connects the soft palate to the tongue’s side.
Origin
-
Genioglossus: inner side of the mandible (chin).
-
Hyoglossus: body and greater horn of the hyoid bone.
-
Styloglossus: styloid process of the temporal bone.
-
Palatoglossus: palatine aponeurosis of the soft palate.
Insertion
-
Genioglossus: underside of the tongue and hyoid bone.
-
Hyoglossus: sides of the tongue.
-
Styloglossus: side and underside of the tongue tip.
-
Palatoglossus: side of the back of the tongue.
Blood Supply
Small branches of the lingual artery supply all four extrinsic muscles, ensuring they get oxygen and nutrients.
Nerve Supply
-
Genioglossus, hyoglossus, styloglossus: all by the hypoglossal nerve (CN XII).
-
Palatoglossus: by the vagus nerve (CN X) via the pharyngeal plexus.
Functions
-
Protrusion (genioglossus) – sticks the tongue out.
-
Retraction (styloglossus) – pulls the tongue back.
-
Depression (hyoglossus) – moves tongue downward.
-
Elevation of back (palatoglossus) – lifts the tongue toward soft palate.
-
Side‑to‑side movement – coordinates tongue shape for speech and swallowing.
-
Tongue anchoring – stabilizes for chewing and breathing.
Types of Sprain
-
Grade I (Mild): Tiny muscle fibers overstretched, minor pain.
-
Grade II (Moderate): Partial tear, clear weakness, moderate pain.
-
Grade III (Severe): Full tear or rupture, significant pain, loss of function.
Causes of Tongue Extrinsic Muscle Sprain
-
Accidental bite: Biting your tongue hard during talking or eating can overstretch a muscle.
-
Sports injury: A blow to the face in contact sports like football can sprain tongue muscles.
-
Motor vehicle crash: Sudden jaw impact can strain extrinsic muscles.
-
Seizure: Violent tongue movements during a seizure cause overstretching.
-
Dental procedure: Long dental work with mouth wide open may strain muscles.
-
Excessive speech: Speaking nonstop for hours without rest can fatigue and sprain.
-
Yelling or singing: Overuse during loud vocal activities strains the tongue.
-
Improper intubation: Medical tube placement in emergency can injure muscles.
-
Trauma to jaw: Broken jaw or heavy tap can pull on tongue muscles.
-
Clenching teeth: Tight jaw clenching can indirectly overstretch extrinsic muscles.
-
High‑impact fall: Hitting the floor face‑first can sprain tongue muscles.
-
Chewing hard food: Biting very tough items without proper chewing rest leads to sprain.
-
Bruxism (teeth grinding): Nighttime grinding fatigues tongue stabilizers.
-
Whiplash: Neck motion in car accidents can jerk tongue muscles.
-
Oral surgery: Procedures on tongue base or soft palate can overstretch extrinsic muscles.
-
Dehydration: Dry tissues are less elastic, more prone to sprain.
-
Sleep apnea device: CPAP mask pressure against tongue at night may strain.
-
Tongue piercing: Jewelry movement can catch and overstretch muscle.
-
Massage error: Poorly performed facial massage may pull on tongue attachments.
-
Neuromuscular disorder: Weakness in support muscles leads to overloading extrinsic fibers.

Frequently Asked Questions (FAQs)
-
What exactly causes a tongue extrinsic muscle sprain?
Overstretching or tearing the muscles that move your tongue, often from trauma or overuse. -
How long does recovery take?
Mild sprains heal in 1–2 weeks; severe tears may take 6–8 weeks or longer with therapy. -
Can I talk during healing?
Limited soft, low‑volume speech is okay after first 48 hours, but avoid straining. -

Gentle tongue stretches prescribed by a speech‑language pathologist help. -
Can massage help?
Yes—light, hygienic massage under the tongue reduces stiffness. -
What diet should I follow?
Soft, nutritious foods like smoothies, yogurt, and pureed soups. -
Is heat or cold better?
Cold packs first 48 hours, then warm compresses after swelling goes down. -
When can I return to sports?
Only after pain‑free full range of motion—often 4–6 weeks. -
Do I need imaging tests?
Only if moderate to severe pain, weakness, or suspected full tear. -
