A stylohyoid muscle sprain is an injury to a small but important muscle in your neck that runs from the base of your skull to the hyoid bone. This guide will help you understand everything—from the muscle’s anatomy and functions to the various causes, symptoms, and treatments.
Anatomy of the Stylohyoid Muscle
Structure & Location
-
Location: The stylohyoid muscle is a slender muscle located in the upper neck. It stretches from the temporal bone (specifically, the styloid process) at the base of the skull down to the hyoid bone, which is a small U-shaped bone in the front of the neck.
Origin & Insertion
-
Origin: The muscle begins at the styloid process, a pointed bony projection on the temporal bone.
-
Insertion: It attaches along the upper border of the hyoid bone.
Blood Supply
-
Arterial Supply: The muscle receives blood from small branches of arteries near the neck and skull, such as branches from the occipital or facial arteries.
Nerve Supply
-
Innervation: It is innervated by a branch of the facial nerve (cranial nerve VII), which helps control its movements.
Functions (Key Roles)
-
Elevation of the Hyoid Bone: Helps lift the hyoid bone during swallowing.
-
Assisting in Swallowing: Works together with other muscles to move food safely down the throat.
-
Speech Articulation: Contributes to the positioning of the hyoid bone, which is important for clear speech.
-
Stabilization: Helps maintain the position of the hyoid bone, providing support to the floor of the mouth.
-
Facilitation of Tongue Movement: Plays a minor role in adjusting the tongue’s position during eating and speaking.
-
Coordination with Other Neck Muscles: Works in concert with other suprahyoid muscles to maintain proper neck function.
Types of Stylohyoid Muscle Sprain
While sprains are more commonly discussed in larger joints, a sprain in a small muscle like the stylohyoid can be categorized based on the severity of the injury:
-
Grade I (Mild):
-
Description: Minor stretching with little to no loss of strength.
-
Symptoms: Slight discomfort and minimal swelling.
-
-
Grade II (Moderate):
-
Description: Partial tearing of muscle fibers.
-
Symptoms: Noticeable pain, swelling, and some limitation in movement.
-
-
Grade III (Severe):
-
Description: Complete rupture of the muscle fibers.
-
Symptoms: Severe pain, significant swelling, and loss of function in the affected area.
-
Additionally, the sprain can be classified as either acute (sudden injury) or chronic (repeated minor injuries that accumulate over time).
