Mylohyoid muscle strain refers to an injury where the fibers of the mylohyoid muscle—located on the floor of the mouth—are overstretched or torn. Because this muscle plays a vital role in swallowing, speaking, and supporting the floor of the mouth, any injury can lead to discomfort and affect daily activities.
Anatomy of the Mylohyoid Muscle
Understanding the mylohyoid muscle’s structure and function is crucial for recognizing how strains occur and how they affect your body.
Structure and Location
-
Location:
The mylohyoid muscle forms the floor of the mouth and lies just above the tongue. -
Origin:
It originates from the mylohyoid line on the inner surface of the mandible (lower jaw). -
Insertion:
The muscle inserts at the hyoid bone and connects at a midline raphe (a seam running along the center).
Blood and Nerve Supply
-
Blood Supply:
The muscle receives blood mainly from the submental branch of the facial artery. In some individuals, branches from the lingual artery also contribute. -
Nerve Supply:
It is innervated by the mylohyoid nerve, which is a branch of the inferior alveolar nerve coming from the mandibular division of the trigeminal nerve (cranial nerve V).
Key Functions of the Mylohyoid Muscle
-
Supports the Floor of the Mouth:
Provides a firm base under the tongue. -
Elevates the Hyoid Bone:
Assists in the swallowing process by lifting the hyoid bone. -
Depresses the Mandible:
Helps in opening the mouth by slightly lowering the jaw. -
Aids in Speech Articulation:
Contributes to the clarity of speech by stabilizing oral structures. -
Stabilizes the Tongue:
Works with other muscles to keep the tongue in proper position. -
Supports Mastication (Chewing):
Plays a role in the complex process of chewing by maintaining proper muscle balance.
Types of Mylohyoid Muscle Strain
Mylohyoid muscle strains can be classified in several ways depending on the injury’s severity and cause:
-
Acute Strain:
A sudden injury typically caused by trauma or a forceful contraction. -
Chronic Strain:
Occurs gradually from repetitive overuse or sustained stress on the muscle. -
Partial Tear:
Only some muscle fibers are damaged. -
Complete Tear:
The muscle is fully ruptured (rare in mylohyoid injuries). -
Isolated Mylohyoid Strain:
The injury is confined solely to the mylohyoid muscle. -
Combined Strain:
The mylohyoid is injured alongside other muscles in the floor of the mouth or jaw region.
Causes of Mylohyoid Muscle Strain
Understanding what might cause a mylohyoid strain can help in both prevention and management. Here are 20 possible causes:
-
Excessive Talking or Singing:
Overuse of the oral muscles. -
Forceful Chewing of Tough Foods:
Straining the muscle with hard-to-chew items. -
Trauma to the Chin or Jaw:
Direct blows can cause sudden strain. -
Dental Procedures:
Prolonged mouth opening during treatments. -

Post-Surgical Complications:
Following oral or jaw surgery. -
Temporomandibular Joint (TMJ) Dysfunction:
Can cause secondary muscle strain. -
Muscle Fatigue:
Overuse without sufficient rest. -
Overextension During Yawning:
