Genioglossus Muscle Sprain

A genioglossus muscle sprain happens when the large fan‑shaped muscle at the floor of your mouth—the genioglossus—gets overstretched or torn. This injury often follows direct trauma, overuse, or sudden force against the tongue, causing pain, weakness, and difficulty with speech and swallowing. RxHarun

Anatomy of the Genioglossus Muscle

A clear understanding of the genioglossus anatomy is essential for grasping how a sprain occurs and why it causes the symptoms it does. RxHarunWikipedia

• Structure & Location:
  The genioglossus is a broad, fan‑shaped extrinsic tongue muscle that forms most of the tongue’s body. It lies on the floor of the mouth, just above the hyoid bone, and fans forward into the tongue.

• Origin:
  It springs from the superior mental spine (genial tubercle) on the inner midline of the mandible (lower jaw).

• Insertion:
  Muscle fibers spread out to attach to the underside of the tongue and the body of the hyoid bone, enabling both tongue protrusion and central depression.

• Blood Supply:
  Branches of the lingual artery—especially the sublingual branch—deliver oxygen and nutrients to the muscle.

• Nerve Supply:
  Motor control is via the hypoglossal nerve (cranial nerve XII); injury to this nerve leads to tongue weakness or deviation.

• Primary Functions:

  1. Protrusion: Pushes the tongue forward out of the mouth.

  2. Depression: Lowers the center of the tongue.

  3. Retraction of Tip: Draws the tongue tip backward and downward.

  4. Airway Stabilization: Keeps the upper airway open during breathing.

  5. Speech Articulation: Shapes tongue movements essential for clear speech.

  6. Swallowing Assistance: Helps push food backward into the throat.

Types of Genioglossus Muscle Sprain

Sprains are graded by severity: RxHarun

1. Grade I (Mild): Overstretching of a few muscle fibers with minimal pain.

2. Grade II (Moderate): Partial tearing of fibers, causing moderate pain and some weakness.

3. Grade III (Severe): Complete rupture of the muscle, leading to severe pain and major loss of function.

Causes of Genioglossus Muscle Sprain

Each of these can overstretch or tear the muscle fibers: RxHarun

1. Accidental Bite: Hard bite during chewing or speaking can overstretch the muscle.

2. Sports Impact: Direct hits to the face in contact sports can strain the tongue muscle.

3. Motor Vehicle Collision: Sudden jaw impact pulls on extrinsic tongue muscles.

4. Seizure Activity: Forceful tongue movements during seizures may sprain fibers.

5. Dental Work: Prolonged mouth opening for procedures can overstretch the muscle.

6. Excessive Talking: Hours of nonstop speech fatigues and strains the muscle.

7. Yelling or Singing: Loud vocal exertion overuses the genioglossus.

8. Improper Intubation: Emergency tube insertion can injure the muscle.

9. Jaw Fracture: Adjacent bone injury pulls on tongue attachments.

10. Teeth Clenching: Chronic clenching tenses and overstretches the tongue base.

11. High‑Impact Fall: Face‑first falls strain extrinsic tongue muscles.

12. Hard Chewing: Biting very tough foods without rest can cause microtears.

13. Bruxism: Nighttime grinding places continuous stress on tongue stabilizers.

14. Whiplash: Rapid neck motion in a crash can jerk the genioglossus.

15. Oral Surgery: Procedures near the tongue base may overstretch fibers.

16. Dehydration: Dry, inflexible tissues are more prone to injury.

17. CPAP Pressure: Improper sleep‑apnea mask fit can press on the tongue.

18. Tongue Piercing: Jewelry movement may catch and overstretch the muscle.

19. Facial Massage Error: Aggressive techniques can pull on tongue attachments.

20. Neuromuscular Weakness: Disorders that weaken surrounding muscles overload the genioglossus.
