Mylohyoid Boutonniere Atrophy is a condition that affects the mylohyoid muscle—a thin, flat muscle that forms the floor of your mouth. Although “boutonniere” usually refers to a deformity seen in fingers, in this context it describes a specific pattern of muscle wasting (atrophy) affecting the mylohyoid.
Anatomy of the Mylohyoid Muscle
Understanding the anatomy of the mylohyoid muscle is key to understanding the condition. Here’s what you need to know:
Location & Structure
Location:
The mylohyoid is located in the floor of the mouth. It runs from the lower jaw (mandible) to the hyoid bone, helping form a muscular sling under the tongue.Structure:
It is a thin, flat, triangular muscle that contributes to the shape and function of the mouth’s floor.
Origin and Insertion
Origin:
The mylohyoid originates along the mylohyoid line on the inner surface of the mandible (lower jaw).Insertion:
Its fibers insert into a central fibrous band called the mylohyoid raphe, which attaches to the hyoid bone.
Blood Supply and Nerve Supply
Blood Supply:
The muscle receives blood from small branches of the facial artery, specifically the submental branch.Nerve Supply:
The mylohyoid is primarily supplied by the mylohyoid nerve, a branch of the inferior alveolar nerve (which itself comes from the mandibular division of the trigeminal nerve, cranial nerve V).
Key Functions
Elevates the Floor of the Mouth:
Helps raise the floor during swallowing.Assists in Swallowing:
Plays a role in the initial stages of moving food to the throat.Supports the Tongue:
Provides a stable base for tongue movements.Aids in Speech:
Contributes to proper articulation by stabilizing the floor of the mouth.Helps in Chewing:
Works with other muscles to maintain the structure needed for effective chewing.Maintains Oral Posture:
Helps keep the mouth’s structure aligned, which is important for breathing and speech.
Types of Mylohyoid Boutonniere Atrophy
While the term “boutonniere” is more commonly linked with finger deformities, when applied to the mylohyoid muscle it can be used to describe patterns or subtypes of muscle atrophy. The condition may be classified into several types based on the underlying cause or severity. Here are a few possible classifications:
Primary Atrophy:
Direct muscle wasting due to disuse or aging without an underlying systemic disease.Secondary Atrophy:
Occurs as a consequence of nerve injury, trauma, or after surgical procedures in the oral or neck region.Localized Atrophy:
Affects only the mylohyoid muscle, often due to localized damage.Systemic Atrophy:
Part of a broader condition involving multiple muscles due to systemic illnesses or neuromuscular disorders.
Causes of Mylohyoid Boutonniere Atrophy
A range of factors can lead to the atrophy of the mylohyoid muscle. Here are 20 potential causes:
Aging:
Natural loss of muscle mass as part of the aging process.Disuse:
Lack of regular muscle use leading to weakening and atrophy.Nerve Injury:
Damage to the mylohyoid nerve from dental procedures or trauma.Trauma:
Physical injury to the head, neck, or jaw area.Surgical Complications:
Postoperative damage from surgeries in the oral or neck regions.Diabetes:
Poor blood sugar control can lead to muscle wasting.Nutritional Deficiencies:
Lack of essential nutrients like protein and vitamins.Radiation Therapy:

Conditions such as myositis where the body attacks its own muscles.Myopathies:
Inherited or acquired muscle disorders.Infections:
Infections in the oral cavity that spread to muscles.Inflammatory Conditions:
Chronic inflammation affecting muscle tissue.Neuromuscular Disorders:
Diseases like amyotrophic lateral sclerosis (ALS) that impair nerve function.Congenital Abnormalities:
Birth defects that affect muscle development.Overuse Injury:
Repeated strain or misuse of the muscle.Obstructive Sleep Apnea:
Altered muscle function due to disrupted sleep patterns.Temporomandibular Joint (TMJ) Disorders:
Issues with the jaw joint affecting muscle function.Post-Stroke Complications:
Stroke-induced nerve damage can lead to muscle atrophy.Medication Side Effects:
