Eagle syndrome

Ea·gle syndrome

pain (usually pharyngeal) and inflammation (usually tonsillar) due to overlong styloid process or calcification about the stylohyoid ligament. Therapy is surgical.
[W.W. Eagle]
A rare condition in which an elongated styloid process— > 30mm—irritates adjacent anatomical structures, in particular the 11th cranial nerve. It is divided into the classic form—due to mechanics—and a vascular form in which the elongated styloid process compresses the extracranial internal carotid artery, when the head is turned, or the carotid artery dissects, evoking a transient ischaemic attack or stroke
Management Surgical—styloidectomy and carotid arterial repair if needed

However, in further discussion he reported long-term mild dysphagia complaints likely related to Eagle syndrome.
Eagle Syndrome was first described in 1937 by Eagle as elongation of the styloid process causing pharyngeal pain, (1) and it is now thought to be an assemblage of symptoms resulting from elongation of the styloid process or progressive calcification of the stylohyoid ligament.
2,3) The diagnosis of Eagle Syndrome is one of exclusion, and it can be confirmed on panoramic radiographs, lateral cervical films, or CT.
2,3) The exact pathophysiology of Eagle syndrome is unclear, although many theories exist.
The pain of Eagle syndrome is typically described as sharp or stabbing neuritic pain with radiation into the tonsillar fossa, temporomandiular joint, and/or base of the tongue.
Eagle syndrome is often a diagnosis of exclusion after other etiologies of pain are thoroughly investigated, and it can be determined via a physical examination and characteristic radiographic findings.
of the stylohyoid ligament, ruling out the possibility of Eagle syndrome.
Causes of symptomatic glossopharyngeal neuralgia include cerebellopontine angle tumors, nasopharyngeal carcinomas, carotid aneurysms, tonsillar abscesses, neurilemmomas of cranial nerve IX, multiple sclerosis, and Eagle syndrome.
We review the anatomy of the peristyloid structures and discuss the etiology, diagnosis, and treatment of Eagle syndrome.
Eagle syndrome comprises a constellation of symptoms which may include facial pain, ear pain, dysphagia, voice changes, and a globus sensation in the throat that prompts frequent swallowing--that occurs secondary to an elongation of the styloid process.
The transcervical surgical approach to resection in patients with elongated styloid processes and Eagle syndrome appears to be safe and effective, although the risk for transient marginal mandibular nerve weakness is notable.
Eagle syndrome represents a constellation of symptoms, most notably facial pain, that are believed to be related to an elongated styloid process.
