Mylohyoid Boutonniere Tumors

Mylohyoid boutonniere tumors are a rare type of growth that occur in the area of the mylohyoid muscle—a thin, flat muscle forming the floor of the mouth. Although the term “boutonniere” is more commonly associated with a specific deformity in other body parts (like the finger), when used with “mylohyoid” it indicates a unique presentation or configuration of the tumor in that region. This guide covers every aspect of these tumors using evidence-based details and plain language. We explain the relevant anatomy, describe the types of tumors, list potential causes and symptoms, detail diagnostic tests and treatment options, and provide advice on prevention and when to seek help.

Anatomy of the Mylohyoid Region

Understanding the mylohyoid muscle and its surrounding anatomy is the first step in grasping the nature of these tumors.

Structure and Location

• Location: The mylohyoid muscle forms the floor of the mouth. It lies just above the jaw (mandible) and below the tongue.

• Significance: It supports the tongue and assists in important functions such as swallowing and speaking.

Origin and Insertion

• Origin: The muscle originates from the mylohyoid line on the inner surface of the mandible.

• Insertion: It stretches across the midline of the floor of the mouth and attaches to the hyoid bone through a fibrous structure called the mylohyoid raphe.

Blood Supply

• Key Vessels: The mylohyoid muscle is primarily supplied by branches of the submental artery (a branch of the facial artery) and possibly small branches from other nearby vessels. This rich blood supply helps maintain tissue health and supports healing.

Nerve Supply

• Innervation: The muscle is innervated by the mylohyoid nerve, which is a branch of the inferior alveolar nerve (itself part of the mandibular division of the trigeminal nerve, cranial nerve V).

Main Functions of the Mylohyoid

1. Forming the Floor of the Mouth: Provides structural support.

2. Aiding in Swallowing: Helps elevate the floor during the act of swallowing.

3. Supporting the Tongue: Maintains proper tongue position for speech and food manipulation.

4. Facilitating Mastication: Plays a minor role in chewing by stabilizing the floor of the mouth.

5. Assisting in Speech: Contributes to clear articulation by maintaining proper oral cavity shape.

6. Stabilizing the Hyoid Bone: Helps secure the hyoid bone, which is crucial for multiple neck and throat functions.

Types of Mylohyoid Boutonniere Tumors

Tumors in the mylohyoid region can be categorized in several ways. They may be benign (non-cancerous) or malignant (cancerous). Some common types include:

• Benign Tumors:

  • Lipomas: Soft, fatty tumors that are generally not harmful.

  • Fibromas: Firm, fibrous tissue growths.

  • Myoepitheliomas: Rare tumors arising from myoepithelial cells.

• Malignant Tumors:

  • Sarcomas: Cancerous tumors that may arise from muscle tissue.

  • Carcinomas: Tumors originating from epithelial cells in the adjacent tissues.

  • Other Rare Malignancies: Less common types that may involve the mylohyoid muscle.

Each tumor type has its own behavior, growth rate, and treatment requirements. Early detection is key, so understanding the signs and getting prompt evaluations can improve outcomes.
