Mylohyoid muscle fibrosis is a condition where the mylohyoid muscle—a key muscle located in the floor of your mouth—develops an abnormal buildup of fibrous tissue. This change can cause the muscle to become stiff and less flexible, affecting its normal function.
Anatomy of the Mylohyoid Muscle
Structure & Location
What is it?
The mylohyoid muscle is a thin, flat muscle that forms the floor of the mouth.Location:
It runs across the lower jaw (mandible) from one side to the other.
Origin & Insertion
Origin:
The muscle begins at the inner surface of the mandible (jawbone).Insertion:
It attaches to a midline structure in the neck, supporting the tongue and floor of the mouth.
Blood Supply & Nerve Supply
Blood Supply:
The mylohyoid muscle is supplied by small blood vessels that branch off from the facial and lingual arteries.Nerve Supply:
It is innervated by nerves from the mandibular branch of the trigeminal nerve, which helps control its movement.
Functions (Key Functions)
Swallowing: Helps raise the floor of the mouth during swallowing.
Speech: Supports proper tongue movement and articulation.
Chewing: Assists in positioning the tongue during mastication.
Stabilization: Provides support to the jaw and floor of the mouth.
Breathing: Plays a minor role in maintaining an open airway.
Oral Hygiene: Aids in the overall movement of oral structures during functions like licking or cleaning the mouth.
Types of Mylohyoid Muscle Fibrosis
While mylohyoid fibrosis is generally categorized by the nature of the fibrous tissue development, types may include:
Localized Fibrosis:
A small, well-defined area of fibrosis that affects only a portion of the muscle.Diffuse Fibrosis:
Widespread scarring throughout the muscle, which may result in more severe symptoms.Post-Traumatic Fibrosis:
Fibrosis that develops after an injury, surgery, or radiation therapy affecting the mylohyoid area.
Causes of Mylohyoid Muscle Fibrosis
Trauma or Injury: Direct impact or accidental injury to the mouth or jaw.
Surgical Procedures: Post-operative scarring after surgeries in the oral or neck region.
Radiation Therapy: Treatment for head and neck cancers can lead to fibrosis.
Infection: Severe infections in the oral cavity may trigger inflammation and subsequent fibrosis.
Inflammatory Conditions: Conditions such as myositis that cause muscle inflammation.
Overuse Injuries: Repeated strain from activities like excessive chewing or grinding.
Muscle Strain: Sudden or chronic overexertion of the muscle.
Idiopathic Causes: Cases where no clear cause is identified.
Autoimmune Disorders: The body’s immune system attacking its own tissues.
Genetic Predisposition: Family history may play a role.
Metabolic Disorders: Conditions like diabetes can contribute to abnormal tissue repair.
Chronic Inflammation: Ongoing low-grade inflammation leading to scar tissue buildup.
Chemical Exposure: Exposure to certain toxins may damage muscle tissue.
Nutritional Deficiencies: Lack of essential nutrients affecting tissue repair.
Stress: Physical or emotional stress that impacts muscle function.
Poor Oral Hygiene: Can lead to infections and subsequent tissue changes.
Smoking: Tobacco use negatively affects tissue healing.
Alcohol Abuse: Excessive alcohol intake can impair muscle repair.
Bruxism: Teeth grinding can indirectly strain the mylohyoid muscle.
Malocclusion: Misaligned teeth may lead to uneven stress on the muscle.
