Mylohyoid boutonniere injury is a term used to describe damage involving the mylohyoid muscle—one of the muscles that forms the floor of your mouth—and the surrounding structures. Although the term “boutonniere” is more commonly used for finger injuries, in this context it helps describe a complex injury pattern that affects the muscle, its attachments, and related tissues.
Anatomy of the Mylohyoid Muscle
Understanding the basic anatomy of the mylohyoid muscle is essential when learning about injuries affecting it.
Structure & Location
Location:
The mylohyoid muscle is found in the floor of the mouth, just under the lower jaw (mandible). It forms a thin, flat sheet that helps support the tongue and other structures.
Origin & Insertion
Origin:
The muscle originates along a bony ridge called the mylohyoid line on the inside of the lower jaw.Insertion:
It runs downward and inward to attach to the hyoid bone—a small, U-shaped bone in the neck—and connects along a midline raphe (a seam where both halves meet).
Blood Supply & Nerve Supply
Blood Supply:
The muscle is primarily supplied by small branches from nearby arteries, including submental branches from the facial artery.Nerve Supply:
It is innervated by the mylohyoid nerve, a branch of the mandibular division (V3) of the trigeminal nerve (cranial nerve V).
Main Functions
Elevating the Floor of the Mouth: Helps raise the mouth floor during swallowing.
Depressing the Lower Jaw: Assists in opening the mouth by working against the jaw muscles.
Assisting in Swallowing: Plays a role in the movement of food from the mouth to the throat.
Stabilizing the Tongue: Supports proper tongue movement and positioning.
Aiding in Speech: Contributes to clear speech by helping with muscle coordination.
Supporting the Hyoid Bone: Works together with other muscles to maintain the position of the hyoid bone during movement.
A mylohyoid boutonniere injury refers to damage that can occur in the mylohyoid muscle and its surrounding attachments. Such an injury may be the result of trauma, overuse, or other factors that cause strain, tearing, or dysfunction in the muscle. The term “boutonniere” suggests a pinched or buttonhole-like lesion, indicating a complex disruption in the normal muscle architecture.
Types of Mylohyoid Boutonniere Injuries
These injuries can vary based on how the muscle is affected. Common types include:
Strain or Overuse Injury: Caused by repetitive stress or excessive use.
Partial Tear: Only some fibers of the muscle are torn.
Complete Tear or Rupture: A more severe injury where the muscle fibers or tendon attachments are completely separated.
Contusion (Bruising): Resulting from a direct blow to the area.
Avulsion Injury: Where the muscle or its tendon is forcibly detached from its attachment.
Causes of Mylohyoid Boutonniere Injury
Here are twenty possible causes that can lead to a mylohyoid boutonniere injury:
Sports Trauma: Direct impact during contact sports.
Falls: Slipping or falling and landing on the jaw.
Motor Vehicle Accidents: Sudden force impacts.
Overuse: Repetitive motion during activities such as chewing or speaking.
Direct Blow: Impact to the chin or submental region.
Dental Procedures: Accidental injury during dental work.
Surgical Complications: Injury during surgeries around the jaw or mouth.
Infections: Infections in the mouth or neck can weaken muscle tissue.
Repetitive Strain: Continuous strain from activities like singing or prolonged speaking.
Insufficient Warm-Up: Lack of proper stretching before exercise.
Muscle Fatigue: Overexertion leading to weakened muscle integrity.
Poor Posture: Chronic poor alignment can strain the muscle.
Sudden Forceful Contraction: Quick, intense muscle contractions.
Degenerative Changes: Wear and tear with aging.
