A tongue transverse muscle contusion is a bruise or injury to the transverse fibers of the tongue—muscle strands that run side-to-side across the tongue’s body. Unlike superficial cuts or lacerations, a contusion involves bleeding within the muscle tissue itself. This can cause swelling, pain, reduced tongue mobility, and difficulty speaking, chewing, or swallowing.
Anatomy of the Transverse Muscle of the Tongue
Understanding contusion starts with the tongue’s structure.
Structure & Location
-
The transverse muscle lies deep within the tongue’s body.
-
Its fibers run horizontally, narrowing the tongue when they contract.
Origin & Insertion
-
Origin: Median fibrous septum (central line of connective tissue in the tongue).
-
Insertion: Lateral margins of the tongue.
Blood Supply
-
Primarily from the lingual artery (a branch of the external carotid).
-
Small branches penetrate the tongue’s intrinsic muscles.
Nerve Supply
-
Motor innervation via the hypoglossal nerve (cranial nerve XII).
-
Sensory from lingual branch of the trigeminal nerve (V3) for general sensation; taste via chorda tympani (branch of facial nerve VII).
Key Functions
-
Tongue Narrowing: Draws tongue edges toward midline.
-
Altering Shape: Helps form speech sounds (e.g., lateral consonants like “l”).
-
Assisting Swallowing: Shapes the food bolus.
-
Oral Cleaning: Aids in moving saliva and debris.
-
Taste Enhancement: Adjusts surface area for taste bud contact.
-
Fine Motor Control: Works in concert with other intrinsic muscles.
Types of Transverse Muscle Contusion
-
Mild (Grade I): Microscopic bleeding, minimal swelling.
-
Moderate (Grade II): Partial fiber tear, more swelling, moderate pain.
-
Severe (Grade III): Full-thickness fiber tear, significant hematoma, marked dysfunction.
-
Bilateral vs. Unilateral: Can affect one side or both sides symmetrically.
-
Acute vs. Chronic: Acute from recent trauma; chronic from repeated minor injuries.
Causes
-
Direct Blow: Accidental hit to mouth (e.g., sports).
-
