What is suspended by stylohyoid ligament?

The hyoid bone lies in the midline at the front of the neck at the level of the fourth cervical vertebra (Badshah et al 2017). It is suspended from the styloid processes by the stylohyoid ligaments and gives attachment to the suprahyoid and infrahyoid groups of muscles.

What does the stylohyoid ligament do?

Structure. The stylohyoid ligament connects the lesser horn of hyoid bone to the styloid process of the temporal bone of the skull.

What causes calcification of stylohyoid ligament?

Calcified stylohyoid ligaments are thought to be the result of post-tonsillectomy or traumatic scarring. Elongated styloid processes develop from variations in embryological development. A styloid process is typically considered to be long when it is more than 30 mm.

Is Eagle syndrome serious?

In rare cases, the long styloid process can put pressure on the internal carotid arteries on either side of your neck. This pressure may cause a stroke. Get immediate emergency care if suddenly experience any of these symptoms: headache.

Can you feel stylohyoid muscle?

The stylohyoid muscle can be palpated by placing the fingers along the direction of the muscle fiber under the chin and superiorly to the hyoid bone. Palpation is done laterally from the hyoid bone towards the ear lobe along the anterior border of the sternocleidomastoid muscle.

Where is hyoid located?

neck
The hyoid bone (hyoid) is a small U-shaped (horseshoe-shaped) solitary bone, situated in the midline of the neck anteriorly at the base of the mandible and posteriorly at the fourth cervical vertebra. Its anatomical position is just superior to the thyroid cartilage.

What does the Stylohyoid muscle do?

The stylohyoid muscle extends between the temporal and hyoid bones. By acting on the hyoid, it facilitates tongue retraction, swallowing (deglutition) and keeps the airway open during inspiration.

What does Eagle syndrome feel like?

Eagle syndrome is characterized by recurrent pain in the middle part of the throat (oropharynx) and face. “Classic Eagle syndrome” is typically seen in patients after throat trauma or tonsillectomy. Symptoms include dull and persistent throat pain that may radiate to the ear and worsen with rotation of the head.

What is the stylohyoid ligament?

The stylohyoid ligament forms part of the styloid apparatus. The origin is at the styloid process of the temporal bone and it inserts into lesser horn of the hyoid bone. The stylohyoid ligament provides part of the origin for the middle pharyngeal constrictor muscle and styloglossus muscle. It develops from the 2 nd branchial arch 2,4.

What is Eagle’s syndrome of the styloid ligament?

Calcification or ossification of the stylohyoid ligament is a frequent, often incidental finding on radiographs, however when the source of pain is from the styloid process or calcified stylohyoid ligaments it is referred to as Eagle’s syndrome.

What causes calcified stylohyoid ligaments?

Calcified stylohyoid ligaments are thought to be the result of post-tonsillectomy or traumatic scarring. Elongated styloid processes develop from variations in embryological development. A styloid process is typically considered to be long when it is more than 30 mm.

What is stylohyoid complex syndrome?

Stylohyoid Complex Syndrome: A New Diagnostic Classification. Objective To describe stylohyoid complex syndrome (SHCS) as a new diagnostic classification of all lateral neck and/or facial pain conditions resulting from an elongated styloid process, ossified stylohyoid ligament, or elongated hyoid bone.
