Mylohyoid muscle tears can affect how you speak, swallow, and even how your lower face feels. In this guide, you’ll learn everything from the basic anatomy to treatments and prevention tips.
Anatomy of the Mylohyoid Muscle
The mylohyoid is a thin, flat muscle forming the floor of the mouth. It plays an important role in swallowing, speaking, and maintaining the position of other structures in the oral cavity.
Structure and Location
-
Location: The mylohyoid runs along the floor of the mouth, forming a muscular sling under the tongue.
-
Appearance: It appears as a thin, flat sheet of muscle fibers.
-
Key Role: Provides support to the tongue and helps in the actions of chewing, swallowing, and speaking.
Origin and Insertion
-
Origin: The muscle fibers start at the mylohyoid line on the inner surface of the mandible (lower jaw bone).
-
Insertion: They insert into a fibrous raphe—a line of connective tissue—running in the midline of the floor of the mouth, as well as attaching to the hyoid bone (a small, U-shaped bone in the neck).
Blood Supply
-
Arterial Supply: The mylohyoid muscle receives blood from branches of the facial artery and the submental artery.
-
Importance: A good blood supply is essential for muscle repair after injury.
Nerve Supply
-
Innervation: It is innervated by the mylohyoid nerve, a branch of the inferior alveolar nerve, which is itself a branch of the mandibular division of the trigeminal nerve (cranial nerve V).
-
Role: This nerve controls muscle movement and helps relay sensations.
Key Functions
-
Elevating the Floor of the Mouth: Helps push food towards the throat during swallowing.
-
Depressing the Mandible: Assists in lowering the jaw during mouth opening.
-
Assisting in Swallowing: Works with other muscles to coordinate the swallowing process.
-
Supporting the Tongue: Provides a stable base for the tongue to move and function properly.
-
Facilitating Speech: Aids in proper articulation by maintaining the floor of the mouth.
-
Stabilizing the Hyoid Bone: Helps secure the hyoid bone, which is crucial for proper neck function and swallowing.
Types of Mylohyoid Muscle Tears
Mylohyoid muscle tears can vary based on severity and the nature of the injury. Common types include:
-
Partial Tear: Only some muscle fibers are damaged.
-
Complete Tear: The muscle is torn completely across its fibers.
-
Strain Injury: Overstretching or overuse leading to micro-tears without a full rupture.
-
Contusion (Bruise): Direct impact causing damage without a full tear.
-
Repetitive Strain Injury: Repeated minor injuries from overuse causing cumulative damage.
Each type may require different treatment approaches, from rest and therapy to surgical repair.
Causes of Mylohyoid Muscle Tears
Below are 20 possible causes of mylohyoid muscle tears. These causes can range from direct trauma to overuse:
-
Direct Trauma: A hit to the jaw or face during accidents.
-
Sports Injuries: Contact sports or falls during physical activities.
-
Motor Vehicle Accidents: Sudden impact causing facial trauma.
-
Dental Procedures: Complications during oral surgery or dental extractions.
-
