Suprahyoid muscles are a group of muscles located above the hyoid bone in your neck. They play a vital role in swallowing, speaking, and moving the jaw. When these muscles become infected, it can lead to significant discomfort and complications.
Suprahyoid muscles infections are uncommon but important to recognize because they can impact breathing, swallowing, and overall neck function. Infections in this area may result from dental issues, trauma, or spread from nearby structures in the head and neck. Early diagnosis and appropriate treatment are essential to prevent further complications.
Anatomy of the Suprahyoid Muscles
Understanding the anatomy of the suprahyoid muscles is key to grasping how infections can affect them. Here’s a breakdown in simple terms:
Structure and Location
-
Location: These muscles are located above the hyoid bone, in the upper neck and floor of the mouth.
-
Main Muscles: The primary muscles include the digastric (with two bellies), mylohyoid, geniohyoid, and stylohyoid.
Origin and Insertion
-
Digastric Muscle:
-
Origin: The anterior belly originates from the digastric fossa of the mandible; the posterior belly originates from the mastoid notch of the temporal bone.
-
Insertion: Both bellies converge and attach to the hyoid bone via an intermediate tendon.
-
-
Mylohyoid Muscle:
-
Origin: Arises from the mylohyoid line on the inside of the mandible.
-
Insertion: Attaches to the hyoid bone.
-
-
Geniohyoid Muscle:
-
Origin: Begins at the inner surface of the mandible near the chin (genial tubercles).
-
Insertion: Inserts on the hyoid bone.
-
-
Stylohyoid Muscle:
-
Origin: Originates from the styloid process of the temporal bone.
-
Insertion: Inserts on the hyoid bone.
-
Blood Supply and Nerve Supply
-
Blood Supply:
-
These muscles receive blood from branches of the external carotid artery and facial artery.
-
-
Nerve Supply:
-
Digastric Muscle: The anterior belly is innervated by the mandibular branch of the trigeminal nerve, while the posterior belly is innervated by the facial nerve.
-
Mylohyoid and Geniohyoid Muscles: Typically supplied by the mylohyoid nerve (a branch of the mandibular nerve).
-
Stylohyoid Muscle: Innervated by the facial nerve.
-
Key Functions
-
Assisting Swallowing: They help elevate the hyoid bone during the swallowing process.
-
Jaw Movement: Aid in opening the jaw (mandibular depression).
-
Speech: Contribute to clear articulation by supporting the floor of the mouth.
-
Maintaining Oral Cavity Structure: Provide support for the tongue and other oral tissues.
-
Breathing: Help maintain airway patency during swallowing and speaking.
-
Lymphatic Drainage Support: Their movement assists in the proper drainage of lymph from the head and neck.
Types of Suprahyoid Muscles Infection
While infections in the suprahyoid region can vary, common types include:
-
Localized Abscess: A pocket of pus in one of the muscles.
-
Cellulitis: A diffuse infection of the soft tissues around the muscles.
-
Myositis: Inflammation of the muscle tissue.
-
Necrotizing Fasciitis: A rare but severe infection that destroys soft tissue.
