Mylohyoid boutonniere cysts are rare, benign, fluid-filled sacs that can develop in or near the mylohyoid muscle—the thin sheet of muscle forming the floor of the mouth. Although these cysts are not common, understanding their anatomy, causes, symptoms, and treatment options is essential for proper diagnosis and management. In this guide, we break down the topic into easily digestible sections for patients, caregivers, and anyone interested in learning more about this condition.
Anatomy of the Mylohyoid and Boutonniere Cysts
A clear understanding of the anatomy is critical for recognizing and managing mylohyoid boutonniere cysts.
Structure and Location
-
Mylohyoid Muscle:
-
A thin, flat muscle that forms the floor of the mouth.
-
It stretches from the lower jaw (mandible) to the hyoid bone.
-
It acts like a sling supporting the tongue and assisting in several oral functions.
-
-
Boutonniere Cysts:
-
“Boutonniere” comes from the French word for “buttonhole” because of the small, rounded shape of the cyst.
-
These cysts appear as a localized swelling or lump in the submental (under the chin) or intraoral (inside the mouth) region, often near the mylohyoid muscle.
-
Origin and Insertion of the Mylohyoid
-
Origin:
-
The mylohyoid muscle originates from the mylohyoid line on the inner surface of the mandible (lower jaw).
-
-
Insertion:
-
It inserts into a midline fibrous raphe and attaches to the body of the hyoid bone.
-
Blood Supply
-
Primary Blood Vessels:
-
The muscle receives blood from branches such as the submental branch of the facial artery.
-
Adequate blood flow is essential for muscle function and healing in case of injury or surgery.
-
Nerve Supply
-
Nervous Innervation:
-
Innervated by the mylohyoid nerve, which is a branch of the inferior alveolar nerve (itself coming from the mandibular branch of the trigeminal nerve).
-
This nerve controls the movement and sensation of the muscle.
-
Key Functions of the Mylohyoid Muscle
-
Support: Provides structural support to the floor of the mouth.
-
Swallowing: Elevates the floor of the mouth during swallowing.
-
Speech: Assists in articulation by stabilizing the tongue.
-
Mastication: Plays a role in the movement required for chewing.
-
Oral Cavity Maintenance: Helps maintain the space and proper shape of the oral cavity.
-
Protection: Offers a protective barrier for deeper structures in the neck and throat.
Types of Mylohyoid Boutonniere Cysts
While not every cyst in the mylohyoid region is a boutonniere cyst, those that are defined by their button-like appearance and location can be categorized into several types:
-
Simple Cysts:
-
Small, fluid-filled sacs with a clear lining.
-
-
Complex Cysts:
-
Cysts with internal septations or multiple compartments.
-
-
Congenital Cysts:
-
Present at birth due to developmental anomalies.
-
-
Traumatic Cysts:
-
Arise following injury or repeated trauma to the area.
-
-
Infectious Cysts:
-
Form secondary to localized infection.
-
-
Inflammatory Cysts:
-
Develop due to chronic inflammation of the surrounding tissues.
-
Each type may differ slightly in appearance, behavior, and required treatment.
Causes of Mylohyoid Boutonniere Cysts
Understanding the possible causes can help with early detection and prevention. Here are 20 potential factors associated with the formation of these cysts:
-
Trauma: Injury to the submental region can trigger cyst formation.
-

Foreign Body Reaction: Reaction to debris or particles entering the tissue.
-
Systemic Infection: Spread of infection from another body area.
-
Iatrogenic Causes: Unintended results from medical or surgical procedures.
-
Mucous Retention: Blocked minor salivary glands causing cyst formation.
-
Ductal Ectasia: Widening of ducts leading to cystic change.
-
Inflammatory Bowel Diseases: Systemic inflammation can sometimes affect oral tissues.
-
Viral Infections: Some viruses may cause local tissue changes.
-
Allergic Reactions: Severe allergies leading to tissue edema and cyst formation.
-
Nutritional Deficiencies: Impact on tissue repair and integrity.
-
Hormonal Imbalances: Changes that may affect tissue health.
