Although rare, Eagle syndrome should be always considered in the differential diagnosis in patients with chronic orofacial pain refractory to conventional treatments. Treatment is surgery and exeresis of the styloid process via a transoral or cervical approach depending on clinical and radiological features.

An elongated styloid process (ESP) is present in 4% of the general population. It is sometimes found incidentally by panoramic radiography or computed tomography in the clinical setting. Few detailed morphometric studies of this phenomenon have been performed, however, especially regarding its histologic aspects. During anatomic dissection of a 71-year-old man who had died from cardiac failure and whose body had been donated to our department for medical student training, an ESP was found while disconnecting the stylohyoid muscle from the hyoid bone...

OBJECTIVE: The calcification of the stylohyoid chain (SHC), elongated styloid process (SP), larger SP' angle and its shortened distance of cervical internal carotid artery (CICA) are risk factors for bony compression and the stylocarotid syndrome. METHODS: 3D-CTAs of 125 patients were analyzed in terms of the SP length, its angulations, type of the SHC and relationships of its proximity to the CICA. RESULTS: Elongated SP was observed frequently both in females (47%) and males (55%)...

A 60-year-old man presented with a 10-month history of of stereotypical spells characterized by vertigo, tinnitus, blurred vision, left hemibody numbness, and occasional syncope, precipitated by turning his head leftwards. Cerebral angiography and CT angiography of the head and neck with provocative maneuvers did not demonstrate vertebral artery narrowing. However, there was narrowing of the left internal jugular vein due to extrinsic compression from the sternocleidomastoid with leftward head rotation in the setting of hypoplasia of the right internal jugular vein...

Background There are only four previous pediatric reports of the glossopharyngeal neuralgic form of the stylohyoid complex syndrome. Stylohyoid complex has merely been described as cases of glossopharyngeal neuralgia in children. Case Report A 12-year-old boy came to our hospital because of recurrent episodes of severe cranial pain (9/10) lasting for 5 to 15 minutes. Pain affected the right tonsillar fossa, ear, and mastoid region. Since the start at the age of 9 years, the frequency of painful episodes has progressively increased: when admitted to our clinics 3 years later, the child was having up to five episodes daily in spite of analgesic, antiepileptic, and antidepressant drugs; he had abandoned school and leisure...

As classically described, Eagle syndrome is an entity where patients develop pain or neurologic manifestations arising from an elongated styloid process and/or an ossified stylohyoid ligament irritating or compressing adjacent cranial nerves or the carotid arteries. Over the past few years, there have been reports of actual injury to the internal carotid artery with dissection, occlusion and strokes. We present three cases identified after blunt trauma-one due to carotid compression and two due to actual injury to the internal carotid artery...

The styloid process arising from the temporal bone is normally about 2.5 cm in length. For various reasons, including trauma and inflammation, it may become elongated. This elongated styloid process, when symptomatic with clinical signs and symptoms suggestive of local compression or neuropathic pain, is termed Eagle syndrome. Glossopharyngeal neuralgia is characterized by intermittent shooting sharp pain in the jaw, throat, tongue, and ear. Conservative management includes anticonvulsants, tricyclic antidepressants, and anti-inflammatory agents...

AIM: Eagle syndrome is a rare entity that causes recurrent throat pain, neck pain, dysphagia, or facial pain by elongated styloid process or calcified stylohyoid ligament. Clinical findings related to the lower cranial nerves compression have also been reported. In some cases it is reported that carotid artery compression or dissection can be seen due to elongated styloid process and it is called carotid artery syndrome. Carotid artery compression causes flow reduction and carotidynia or neurological symptoms can be seen...

INTRODUCTION: Clinical presentation of Eagle syndrome (ES) is very variable and non-specific, making its diagnosis difficult. It is usually limited to pain. Transient neurological manifestations are exceptional. We report one case in which the diagnosis of ES has been made based on neurological events occurring during left anterolateral head bending, without pain. OBSERVATION: A 47-year-old man presented with transient neurological events progressing since two years, half-right body paresthesia and reduced field of vision on the left side type, triggered by left anterolateral head flexion and regressive in neutral position...

The objective of this study was to determine the precise departure points of the articular branches innervating the distal radio-ulnar joint from the anterior and posterior interosseous nerves. The study sample consisted of 116 upper limbs from adult human cadavers. The articular branches were prepared under the dissection microscope to take measurements using the radial styloid process as point of reference. The articular branch departed from the anterior interosseous nerve at a mean distance of 2.9 cm proximal to the styloid for a radius length of 20...

PURPOSE: The tongue is a highly muscular organ, and the extrinsic muscles of the tongue overlap one another, which makes their configuration intricate. The aim was to clarify their spatial interrelationships. METHODS: The extrinsic muscles of the tongue were gross anatomically investigated in 42 cadavers. RESULTS: The hyoglossus consisted of two parts arising from the hyoid body and the greater horn, respectively. They ascended to the tongue external to the genioglossus...

Eagle syndrome is a rare condition resulting from elongation of the temporal styloid process or calcification of its associated stylohyoid ligaments. Although usually presenting with pain or odynophagia, Eagle syndrome has been reported to cause a multitude of neurologic symptoms or vascular complications, some of which can be life-threatening. We present a case in which an endovascularly placed internal carotid artery stent in close proximity to a calcified stylohyoid ligament resulted in stent fracture with subsequent stent and vessel occlusion...

Eagle syndrome is a well-known disease caused by elongation of the styloid process and/or calcification of the stylohyoid ligament, which interferes with adjacent anatomical structures, giving rise to acute cerebrovascular syndrome(ACVS)and/or pain. Although hyoid bone is also a stylohyoid complex, its association with ACVS is not well known. Thus, we investigated the anatomical relationship between the internal carotid artery(ICA)and the hyoid bone. Between January 2014 and December 2015, three-dimensional computed tomographic angiography(3D-CTA)of the neck was performed for 218 patients...
