Suprahyoid muscles are a group of muscles located above the hyoid bone in the neck. They play a key role in actions such as swallowing, speaking, and jaw movement.
Suprahyoid muscle injuries can result from various causes—from a minor strain during sports or dental work to more severe trauma. These injuries might lead to pain, difficulty swallowing, and restricted movement of the jaw. Because the suprahyoid muscles are integral to several everyday functions, understanding their structure and how to care for them is essential. This guide aims to present clear and evidence-based details about the injury, its underlying anatomy, potential causes and symptoms, diagnostic methods, treatments, and preventive steps. Whether you are a patient seeking information or a caregiver looking for guidance, this article covers everything you need to know.
Anatomy of the Suprahyoid Muscles
A solid understanding of the anatomy of the suprahyoid muscles is the first step in grasping how injuries can affect their function.
Structure and Location
-
Location: The suprahyoid muscles are located above the hyoid bone, a small, U-shaped bone in the neck. They form the floor of the mouth and are essential in linking the jaw to the neck.
-
Muscles Included: The main muscles in this group include:
-
Digastric (anterior and posterior bellies)
-
Mylohyoid
-
Geniohyoid
-
Stylohyoid
-
Origin and Insertion
-
Digastric Muscle:
-
Origin: The anterior belly originates from the digastric fossa of the mandible (lower jaw), while the posterior belly arises from the mastoid notch of the temporal bone.
-
Insertion: Both bellies join at an intermediate tendon, which attaches to the hyoid bone.
-
-
Mylohyoid Muscle:
-
Origin: Arises from the mylohyoid line on the inside of the mandible.
-
Insertion: Inserts along the midline at the body of the hyoid bone, forming a muscular floor of the mouth.
-
-
Geniohyoid Muscle:
-
Origin: Starts from the inferior mental spine of the mandible.
-
Insertion: Inserts onto the body of the hyoid bone.
-
-
Stylohyoid Muscle:
-
Origin: Begins at the styloid process of the temporal bone.
-
Insertion: Attaches to the hyoid bone near its upper border.
-
Blood Supply
-
Arterial Supply:
-
The suprahyoid muscles receive blood mainly from branches of the external carotid artery.
-
Smaller vessels from the facial and lingual arteries also contribute to the blood supply.
-
Nerve Supply
-
Innervation:
-
The muscles are primarily supplied by cranial nerves and cervical nerves. For example, the mylohyoid and anterior belly of the digastric are innervated by the mylohyoid nerve, a branch of the mandibular division of the trigeminal nerve (CN V3).
-
Other muscles receive nerve supply from branches of the facial nerve (CN VII) and hypoglossal nerve (CN XII), ensuring proper muscle coordination for swallowing and speech.
-
Key Functions of the Suprahyoid Muscles
-
Elevation of the Hyoid Bone: Essential for swallowing, these muscles lift the hyoid bone during the act of swallowing.
-
Depression of the Mandible: They help open the jaw, allowing for the intake of food and air.
-
Stabilization of the Floor of the Mouth: They provide support to the mouth’s base during speech and swallowing.
-
Assistance in Tongue Movement: By influencing the position of the hyoid, they indirectly aid in proper tongue movement.
-
Facilitating Breathing: Their coordination helps maintain an open airway during various activities.
-
Contributing to Facial Expressions: They can influence the tension in the lower face during expressions and speech.
Types of Suprahyoid Muscle Injuries
Though injuries to the suprahyoid muscles are less common than those in larger muscle groups, several types have been identified:
-
Acute Strain: A sudden stretch or minor tear from overuse or direct trauma.
-
Chronic Overuse Injury: Repeated minor injuries due to continuous overexertion (common in professions such as singing or in people with bruxism).
-
Contusion (Bruise): Caused by a blunt force injury that results in bleeding and swelling within the muscle.
-
Partial Tear: A more significant injury where only some muscle fibers are torn.
-
Complete Rupture: A severe injury with full tearing of the muscle, which may require surgical intervention.
