Mylohyoid muscle neuralgia is a condition involving pain related to the mylohyoid muscle—a small, thin muscle that forms part of the floor of your mouth. When the nerve supply to this muscle is irritated or injured, it can cause sharp or dull pain.
Anatomy of the Mylohyoid Muscle
Understanding the anatomy of the mylohyoid muscle is the first step in grasping the cause and management of its neuralgia.
Structure and Location
-
What It Is: The mylohyoid muscle is a flat, triangular muscle.
-
Where It Is Located: It forms the floor of the mouth, stretching from one side of the jaw to the other.
-
Role in the Mouth: This muscle helps support the tongue and aids in swallowing.
Origin and Insertion
-
Origin: The mylohyoid muscle originates from the mylohyoid line on the inner surface of the mandible (lower jaw).
-
Insertion: It inserts into a midline raphe (a fibrous seam) on the underside of the tongue and hyoid bone, which is a small bone in the neck.
Blood Supply
-
Main Arteries: The muscle receives blood from small branches of the submental and facial arteries.
-
Function of Blood Supply: This blood flow helps deliver oxygen and nutrients to the muscle, ensuring its proper function.
Nerve Supply
-
Primary Nerve: The mylohyoid nerve, a branch of the inferior alveolar nerve (itself a branch of the mandibular division of the trigeminal nerve), supplies the muscle.
-
Role of the Nerve: This nerve controls the muscle’s movement and relays sensory information, which means any irritation can result in pain (neuralgia).
Functions of the Mylohyoid Muscle
-
Swallowing: Helps elevate the floor of the mouth during swallowing.
-
Speech: Contributes to articulation by supporting tongue movement.
-
Chewing: Stabilizes the tongue and assists in moving food.
-
Maintaining Oral Posture: Helps support the position of the tongue at rest.
-
Assisting in Breathing: Plays a minor role in maintaining an open airway.
-
Facilitating Saliva Movement: Aids in the natural movement and flow of saliva within the mouth.
Mylohyoid muscle neuralgia is pain that occurs when the nerve (mylohyoid nerve) supplying the muscle is irritated or injured. This neuralgia can cause sharp, shooting, or burning pain that may affect the lower jaw, floor of the mouth, and even radiate to nearby areas.
Types of Mylohyoid Muscle Neuralgia
While research on mylohyoid muscle neuralgia is still growing, the condition can generally be classified into a few types based on its cause and presentation:
-
Primary Neuralgia: Occurs without any clear external cause. It may be due to nerve degeneration or idiopathic (unknown) factors.
-
Secondary Neuralgia: Develops as a result of another condition, such as trauma, infection, dental procedures, or systemic diseases.
-
Chronic Neuralgia: A long-lasting form where pain persists for months or even years.
-
Acute Neuralgia: Pain that begins suddenly and is of short duration.
-
Recurrent Neuralgia: Episodes of pain that occur repeatedly over time.
Causes of Mylohyoid Muscle Neuralgia
Below are 20 potential causes that may contribute to this type of neuralgia:
-
Dental Procedures: Invasive dental work can irritate the nerve.
-
Trauma: Injury to the jaw or face can damage the nerve.
