What does the stylomandibular ligament do?
The stylomandibular ligament (STML) arises from the styloid process of the temporal bone up to the posterior margin of the jaw or the jaw angle. It is considered a thickening of the deep cervical fascia (in particular of the parotid fascia). It serves to limit excessive protrusion of the jaw.
Where does stylomandibular ligament attach?
The stylomandibular ligament (STML) is a specialized dense, local concentration of deep cervical fascia extending from the apex of the styloid process. It is inserted medially into the angle and posterior border of the mandible with a 30° angle of inclination (Figure 5).
What is Ernest syndrome?
Ernest Syndrome is a condition affecting a tough, fibrous band of tissue that connects a pointed bone below the ear (the Styloid bone) to the lower curve of the jaw bone (mandible). This band of tissue stretching from the ear to jaw is called the Stylomandibular Ligament.
How is Eagle syndrome diagnosed?
Eagle syndrome is diagnosed based on a two-step process: Physical exam. The doctor will take the patient’s medical history, learn about his or her symptoms, and then examine the neck and inside the mouth. CT scan.
Why is it called Eagle syndrome?
The condition is named after an ear, nose and throat specialist called Watt Weems Eagle (Duke University in North Carolina, USA) who first described it in 1937. Another term used to describe the condition is stylohyoid syndrome.
Can you feel the styloid process?
It should be possible to feel an elongated styloid process by careful intraoral palpation, placing the index finger in the tonsillar fossa and applying gentle pressure. If pain is reproduced by palpation and either referred to the ear, face, or head, the diagnosis of an elongated styloid process is very likely.
How do you fix Eagle syndrome?
Medical therapy is first-line treatment for Eagle syndrome. Surgery with resection of the elongated styloid process is considered to be definitive treatment, however, surgery may be contraindicated in some cases or patients may decline operative intervention.
